Harvesting seaweed must be handled carefully and transported with environmentally friendly non-motorized fishing boats.
The terms "seaweeds" and "sea vegetables" are used interchangeably herein and refer to the large, visible macroalgae growing attached to each other, rocks, and the seafloor in the intertidal zone and shallow seawater. Microalgae, phytoplankton, cyanobacteria (blue-green algae) and eel grasses are not included. The term "sea herbs" is not used and not recommended since it compromises the true cryptogamic identity and phylogenetic classification of the macroalgae, even though it is used affectionately by herbalists. The term "seaweed" is a bit misleading: with a few notable exceptions, seaweeds are actually saltwater-tolerant, land-dependent plants growing almost exclusively at the narrow interface where land and sea meet. Most must be firmly attached to something to stay in the "photic zone", where they can receive sufficient sunlight.

All seaweeds are photosynthetic. The best-known truly "pelagic" seaweed (pelagic means living and growing at sea, independent of land) is Sargasso weed, a prolific brown seaweed of the genus Sargassum. This lush plant covers an area of 7000 square miles near the Bermuda Triangle, with a floating layer 1-2 feet thick; modest wave action sorts it out into long even rows that resemble a carefully-planted field on land. After several days of slowly chugging through the Sargasso Sea while taking transatlantic transect vertical plankton tows, I experienced a common visual hallucination and urge to jump off the boat and walk around on the Sargasso weed as had many mariners before me. The urge was compelling. I nearly had to be restrained.


Sea vegetables
have been consumed regularly by all coastal peoples since the first days.
Seaweeds are best used as regular components of a wise diet. Sea vegetables have been consumed regularly by all coastal peoples since the first days. Special harvesting, processing, storage, and eating rituals evolved to meet local needs. The ease of drying sea vegetables in full sunlight, and, their innate long-term stability when kept completely dry permits safe long-term storage and facilitates both personal and commercial transport, And, an almost indefinite shelf-life when stored completely dry and away from light.

Worldwide post-industrial healthy living consciousness has in the most recent score of years initiated a very deliberate increase in overt human dietary seaweed consumption, especially in the more-developed postindustrial nations where voluntary vegetarian and macrobiotic diets are increasingly popular. Most east Asian populations (Japan, Korea, china) continue to eat large amounts of seaweed per capita. Japan has the highest per capita dietary


Japan has the highest per capita dietary sea vegetable consumption (and, correspondingly, the highest per capita dietary iodine consumption, and, an extremely low incidence of breast cancer).
sea vegetable consumption (and, correspondingly, the highest per capita dietary iodine consumption, and, an extremely low incidence of breast cancer). In the most developed countries, covert sea vegetable product consumption by the average person probably far exceeds overt consumption. This results from the widespread use of several phycocolloids as food additives for both bulking foods with cheap water (carageenan from the red algae Chondrus crispus, Irish moss, and Gigartina spp., grapestone) where the clathritic capacity of the phycocolloid to control large amounts of water in a semisolid gel makes for an even texture and distribution of favor and clobbering, as in cheap frozen semi-dairy confections; and, for stabilizing semisolid structure, as in ice cream, where about one pound of the brown seaweed extract algin is used to stabilize a ton of ice cream.

Malnutrition affecting '3m in UK'

Malnourishment costs £13bn a year in health costs
People suffering from malnutrition - or at risk of it - in the UK stands at three million, experts believe.
It is the clearest idea yet of the scale of the problem after those in the community as well as hospitals and care homes were included in the count.
The British Association for Parenteral and Enteral Nutrition said the problem was costing £13bn a year to treat and urged GPs to do more.
But GPs said that it was already being taken seriously.
BAPEN's report looked at previous research on the extent of malnutrition in a range of settings from hospitals and mental health units to sheltered housing and care homes.
Researchers estimated that of the three million either malnourished or at risk of malnutrition, 93% were living at home or in sheltered accommodation, 5% were in care homes and 3% in hospitals and other NHS settings.
The emphasis must now be on prevention and that means spotting it in the community
Professor Marinos Elia, report author
Viewpoint: Malnutrition matters
They said elderly people, particularly those with long-term conditions, were most at risk, although isolation and poverty also played key roles.
The association, together with a range of charities, have been campaigning about nutrition for years.
The pressure has resulted in a number of improvements, including more screening and better food in hospitals and care homes.
But BAPEN said it was now time for GPs to do more.
Under guidelines, they are meant to use the official malnutrition screening checklist, which measures weight, height and any recent weight loss to give a malnutrition risk score, when they believe someone might be at risk.
But the association said this was still not being done routinely and urged ministers to include more incentives in the GP contract.
Cost
The report said the health cost of the problem was also likely to be in the region of £13bn - twice as high as some previous estimates.
Malnourished people stay in hospital longer, succumb to infection more often and visit their GP more frequently.
Professor Marinos Elia, one of the lead authors of the report and a former chair of BAPEN, said: "The evidence is clear and the time is right.
"The emphasis must now be on prevention and that means spotting it in the community."
As well as GPs, he said pharmacists could get involved in community screening, while transport planners could do more to ensure people had good links to supermarkets.
Pamela Holmes, of Help the Aged, said: "Malnutrition in the community is drastically overlooked.
"Social workers, community nurses, GPs and other health professionals need to be educated and trained to spot and treat the signs of malnutrition."
Professor Steve Field, of the Royal College of GPs, said: "It is a very important issue, but I think it is something GPs are already taking seriously.
"We routinely weigh and measure patients so I don't think it is necessary to change the GP contract."
Government response
But the Department of Health in England said despite the problems being reported overall people were getting healthier.
A spokeswoman said: "The Department recognises that good diet and nutrition are important for everyone.
"Sustained investment in tackling health inequalities has paid off. Life expectancy in England is the highest it has ever been, including in disadvantaged areas.
"We are committed to reducing health inequalities further, and have put in place the most comprehensive programme ever in this country to address them."
She also pointed out the Nutrition Action Plan published in Autumn 2007 specifically aimed to address the issue of malnutrition in care homes and hospitals by encouraging screening and staff training as well as issuing guidance.

asthma

Pregnant women who suffer from stress are more likely to have a child with asthma, according to research from Children of the 90s study.
Researchers working with about 6,000 families in Bristol found anxious mums-to-be were 60% more likely to have a baby who would develop the illness.
The findings show 16% of asthmatic children had mothers who reported high anxiety while pregnant.
Mothers-to-be who were less stressed had a lower incidence rate.
Key findings
Professor John Henderson, from the Children of the 90s team, said: "Perhaps the natural response to stress which produces a variety of hormones in the body may have an influence on the developing infant and their developing immune system that manifests itself later on."
The Children of the 90s study - carried out by the University of Bristol - has been following 14,000 children.
They are regularly tested and monitored to see how different lifestyles affect growth, intelligence and health.
The aim is to identify ways to optimise the health and development of children.
Key findings to come out of the project include left-handed children do less well in tests than their right-handed peers and women who eat oily fish while pregnant have children with better visual development.

biofuel debate favourite arguments of climate-change deniers.

Natural mechanism for medieval warming discovered


Europe basked in unusually warm weather in medieval times, but why has been open to debate. Now the natural climate mechanism that caused the mild spell seems to have been pinpointed.
The finding is significant today because, according to Valerie Trouet at the Swiss Federal Institute for Forest, Snow, and Landscape Research in Birmensdorf, the mechanism that caused the warm spell in Europe – and meant wine could be produced in England as it is now – cannot explain current warming. It means the medieval warm period was mainly a regional phenomenon caused by altered heat distribution rather than a global phenomenon.
The finding scuppers one of the favourite arguments of climate-change deniers. If Europe had temperature increases before we started emitting large amounts of greenhouse gases, their argument goes, then maybe the current global warming isn't caused by humans, either.
To work out what the global climate was doing 1000 years ago during the so-called "Medieval Warm Period", Trouet and colleagues started by looking at the annual growth rings of Moroccan Atlas cedar trees and of a stalagmite that grew in a Scottish cave beneath a peat bog. This revealed how dry or wet it has been in those regions over the last 1000 years.
The weather in Scotland is highly influenced by a semi-permanent pressure system called the Icelandic Low, and that in Morocco by another called the Azores High. "So by combining our data, which showed a very wet medieval Scotland and very dry Morocco, we could work out how big the pressure difference between those areas was during that time," says Trouet.

Warm blast

This pressure difference in turn revealed that the medieval period must have experienced a strongly positive North Atlantic Oscillation (NAO) – the ocean current that drives winds from the Atlantic over Europe. The more positive the NAO is, the more warm air is blown towards the continent.
The idea to use growth rings to work out past climate change is not new, but Trouet's team is the first to look back beyond 1400 in the European record. They found that the strongly positive NAO lasted for about 350 years from 1050 to 1400.
By combining their data with information from other regions of the world during medieval times and plugging it into different models, the researchers have also come up with a hypothesis of what made the warm winds so persistent.
"It turns out that in the tropical Pacific, the El Niño system was in a negative La Niña mode, meaning it was colder than normal," says Trouet.

Climate loop

El Niño and the NAO are connected by a process called thermohaline circulation, which drives the "ocean conveyor belt" that shuttles sea water of different density around the world's oceans.
According to Trouet, a Pacific La Niña mode and a positive NAO mode could have reinforced each other in a positive feedback loop – and this could explain the stability of the medieval climate anomaly.
Trouet thinks external forces like abrupt changes in solar output or volcanism must have started and stopped the cycle, and hopes to pinpoint the most likely candidates in a workshop with other climatologists in May.

'Profound implications'

Michael Mann at Pennsylvania State University says that based on the analyses and modelling that he has done, increased solar output and a reduction in volcanoes spouting cooling ash into the atmosphere could have not only kicked off the medieval warming, but might also have maintained it directly.
Mann is also concerned that the dominance of medieval La Niña conditions now indicated by Trouet's work might make it more likely that the current man-made warming could also put the El Niño system back into a La Niña mode, although most climate models so far had predicted the opposite.
"If this happens, then the implications are profound, because regions that are already suffering from increased droughts as a result of climate warming, like western North America, will become even drier if La Niña prevails in the future", he says.

Oh! really what a surprise, surprise

Homeless need mental health help

Homeless man
The number of homeless is expected to rise this year

Homeless people need more help to deal with mental health problems, leading charities are warning.

Experts have already predicted that the recession could lead to a rise in homeless people.

And now Crisis and St Mungo's have called for improved access to specialist services because of the high rates of problems being reported.

Research shows that a third of people in hostels have severe mental health problems such as personality disorders.

Once other conditions, including depression and anxiety, are taken into account as many as eight in 10 are affected.

The link between homelessness and mental health problems is well known
Leslie Morphy, of Crisis

But the charities, which run homelessness services including hostels, said most are given no help.

One of the key reasons why homeless people struggle to access services when they want to is that they are often not registered with a local GP.

The campaigners called for mental health specialists to run outreach clinics in hostels as well as greater access to drop-in centres.

They are now planning to hold discussions over the next 10 weeks with other homeless services, NHS experts and social services to see what can be achieved, before publishing a full report in the summer.

While the number of rough sleepers has been falling in recent years, there are still estimated to be about 800 people on the streets of the UK at any one time.

On top of that there are more than 40,000 people living temporarily in shelters and hostels.

Rise

And many believe these figures will rise in the coming months as people struggle to cope in the current financial climate.

St Mungo's chief executive Charles Fraser said: "These are often the individuals with the most intractable problems, who need the most determined help and it is reprehensible they are not getting it."

And Leslie Morphy, the head of Crisis, added: "The link between homelessness and mental health problems is well known.

"Yet, despite all the evidence, we still do not have the right services and support in place to address what is both such a common cause and consequence of homelessness."

But the Department of Health said funding for mental health services had been increasing and local health bosses were investing some of this into care for homeless people.

"Many trusts now have successful community outreach teams that work with hard to reach people such as the homeless."

Warning of food price hike crisis

Sausages
The price of pork sausages has gone up 51% in the past year

A crisis is unfolding in the UK as people in poverty struggle with rising food prices and the recession, the Save the Children charity has warned.

It comes as new figures from The Grocer magazine show food prices rose by more than 18% over the last year.

On Monday, the charity will launch a crisis grant scheme to help families.

The government says it believes food prices have peaked and it is tackling child poverty through increased child benefits and child tax credits.

'More unequal'

Colette Marshall, of Save the Children, said: "We are facing a crisis. Benefits simply haven't been enough and with rising food costs it means that families cannot afford to give children proper decent food.

"We think we are heading towards malnutrition here in the UK."

Pensioner on her struggle with food costs

She is calling on the government to meet its target of halving child poverty by 2010 by putting £3bn in the Budget.

Penny Greenhough, a single mother of two young children, said the family was struggling on a food budget of £3 per head per day.

"I am having to compromise on a daily basis on quality and quantity. I used to manage, but it's getting harder and harder," she told BBC News.

"Once you get into the supermarket then you have got to start looking for the cheapest of everything, every type of commodity you want, whether it is soap powder, some meat or bread or anything else, it's always the cheapest variety," said pensioner Rita Young.

"We have to go for the cheapest of everything and it's just not doing us any good. Too much salt, too much fat, too much sugar - cheap, cheap, cheap, just isn't good enough."

ANNUAL FOOD PRICE RISES
Rice - up 81%
Pork sausages - up 51%
Mince - up 22%
Milk - up 14%
Source: The Grocer

Kate Green, of the Child Poverty Action Group, said that many families were buying less fresh fruit, vegetables, meat and fish, and consuming more affordable tinned and packet food that was often higher in sugar, salt and fat.

Government efforts had lifted 600,000 children out of poverty in the last 10 years, but one in three still lived below the poverty line, she said.

"Part of the problem is... many people have seen their prosperity improve over the last 10 years, so we have become a much more unequal country," she said.

"That is very damaging for the people who just haven't kept up, and it really is quite wrong morally, and it's economically very stupid actually, not to make sure that we share the resources more equally and protect those who have least."

According to The Grocer, a typical basket of 33 items of food cost £48 a year ago. That has now risen to £57.50.

Seasonal produce has caused a small drop in monthly figures, but the cost of basic essentials remains high.

Extra benefits

James Ball, from the magazine, told the BBC: "It is the staples that have really gone up and that's tough for people who buy the cheapest food.

"Rice costs double what it did last year, baked beans are up more than a third. Lots of everyday items cost a lot more than they used to."

As the UK imports about 40% of its food, the weak pound has driven up prices. Unpredictable world harvests and a spike in oil prices last year have also played a part.

However, as British produce comes into season, prices are expected to drop.

Treasury minister Stephen Timms said a raft of benefits due to come in on Monday would help struggling families.

"Extra help on child benefit, child tax credit, the state pension, and pension credits is going to assist children, families and older people who are feeling the pinch at the moment.

"Of course we always look at the time of the budget to see if there is more that can be done but I think people will appreciate the help that is being provided."

Polypill 'could become a reality'

Heart pill
The polypill has been hailed as the magic bullet to heart problems

A cheap five-in-one pill can guard against heart attacks and stroke, research suggests.

The concept of a polypill for everyone over 55 to cut heart disease by up to 80% was mooted over five years ago, but slow progress has been made since.

Now a trial in India shows such a pill has the desired effects and is safe and well-tolerated by those who take it.

Although The Lancet study is proof of concept, experts still question the ethics of a pill for lifestyle issues.

There is a danger that lifestyle factors could be overlooked in favour of 'popping a pill'
Mike Rich of UK charity the Blood Pressure Association

Q&A: The Polypill

Critics say the problems of high blood pressure and cholesterol should be tackled with diet and exercise rather than by popping a pill.

The polypill used in the latest study combines five active pharmacological ingredients widely available separately - aspirin, a statin to lower cholesterol and three blood pressure-lowering drugs - as well as folic acid.

Does what it says on the tin

Trials on 2,053 healthy individuals free of cardiovascular disease, but with a risk factor such as high blood pressure or a long-term smoker, showed combining the drugs into one tablet delivered a similar effect to each drug separately.

Reductions were seen in both blood pressure and cholesterol without any major side effects.

WHAT'S IN IT?
Aspirin to thin the blood
A statin drug to lower cholesterol
Three blood pressure-lowering drugs:
ACE inhibitor
Diuretic
Beta-blocker
Folic acid to reduce the level of homocysteine in the blood which is another risk factor for heart disease

The researchers believe that the combined action of all the components in their "Polycap" capsule made by Cadila Pharmaceuticals, could potentially halve strokes and heart attacks in average, middle-aged people.

On a global scale, this would save tens of millions of lives.

The study, led by Dr Salim Yusuf, from McMaster University in Ontario, Canada, took in people at 50 centres across India.

A spokeswoman for the British Heart Foundation said: "The results suggest that the polypill has the potential to reduce the incidence of cardiovascular disease.

The polypill does exactly what it should, but no more
UK researcher Professor Simon Thom

"We now need further research to examine whether the polypill actually reduces mortality."

A UK team led by Professor Simon Thom of Imperial College London is hoping to do just this.

They have been testing a four-in-one polypill called the Red Heart Pill, with the backing of the Wellcome Trust and the British Heart Foundation, which could cost as little as 15 euros per person per year.

Professor Thom said it would be at least five years before there was enough data to convince drug regulators to approve a polypill.

"Mounting evidence shows the polypill does exactly what it should, but no more, whereas exercise has wide reaching effects on health and wellbeing. So a polypill is an addition rather than a replacement for lifestyle interventions."

FROM THE TODAY PROGRAMME

More from Today programme

Mike Rich of UK charity the Blood Pressure Association said: "This study further stimulates the debate over whether a 'magic bullet' is the answer to the prevention of heart disease and strokes.

"Eating healthily and taking regular exercise are proven ways to lower high blood pressure - and have many other health benefits too - and there is a danger that these lifestyle factors could be overlooked in favour of 'popping a pill'."

Joanne Murphy of The Stroke Association said: "By combining these medications in one pill, it will make it easier for people to take their medication. However, it is important that more research and investigation is done into this pill to ensure its safety."

One GP, Dr Sarah Jarvis, said the pill should not be viewed as an alternative to improving lifestyles through diet and exercise.

"What we need to bear in mind is that this may well cut the likelihood of dying of heart disease dramatically. Fantastic. But it's not going to stop you getting arthritis, it's not going to stop you get lung disease," she said

common infections

How infection may spark leukaemia

Leukaemia cells
Common infections may trigger cancer cell growth

Scientists have shown how common infections might trigger childhood leukaemia.

They have identified a molecule, TGF, produced by the body in response to infection that stimulates development of the disease.

It triggers multiplication of pre-cancerous stem cells at the expense of healthy counterparts.

The Institute of Cancer Research study appears in the Journal of Clinical Investigation.

While infection is clearly only one factor in triggering progression, this study greatly increases the strength of evidence for its role in the commonest form of childhood leukaemia
Dr Shabih Syed
Leukaemia Research

Leukaemia occurs when large numbers of white blood cells take over the bone marrow, leaving the body unable to produce enough normal blood cells.

The researchers had already identified a genetic mutation - a fusion of two genes - occurring in the womb that creates pre-leukaemic cells.

These cells then grow in the bone marrow, effectively acting as a silent time bomb that can stay in the body for up to 15 years.

Evidence suggests the mutation may be present in as many as one in 100 newborn babies, but only about one in 100 of these children then go on to develop leukaemia.

This suggests that the cells will only complete the transformation to fully-fledged cancer cells if they exposed to an independent trigger.

The latest study suggests production of TGF in response to an infection could be that trigger.

Because the molecule hugely increases the rate at which the pre-leukaemic cells multiply, this significantly raises the the chance that some will become even further damaged in a way that results in the child developing leukaemia.

Preventative measures

Researcher Professor Mel Greaves said: "Identifying this step means we can determine how an unusual immune response to infection may trigger the development of the full leukaemia and eventually perhaps develop preventative measures such as a vaccine."

Dr Shabih Syed, scientific director at the charity Leukaemia Research, said: "Before this study, there had been only circumstantial evidence to implicate infections in the progression from a child carrying pre-leukaemic cells to actually having leukaemia.

"There was no evidence of the mechanism by which this might happen.

"While infection is clearly only one factor in triggering progression, this study greatly increases the strength of evidence for its role in the commonest form of childhood leukaemia."

Shopping sprees linked to periods

Sarah Jessica Parker, as Carrie Bradshaw, in Sex and The City
Sex and the City character Carrie Bradshaw loves to shop

Women may be able to blame impulse buys and extravagant shopping on their time of the month, research suggests.

In the 10 days before their periods began women were more likely to go on a spending spree, a study found.

Psychologists believe shopping could be a way for premenstrual women to deal with the negative emotions created by their hormonal changes.

Professor Karen Pine will present her work to a British Psychological Society meeting in Brighton later this week.

She asked 443 women aged 18 to 50 about their spending habits.

The spending behaviour tends to be a reaction to intense emotions
Professor Pine

Almost two-thirds of the 153 women studied who were in the later stages of their menstrual cycle - known as the luteal phase - admitted they had bought something on an impulse and more than half said they had overspent by more than £25.

A handful of the women said they had overspent by more than £250.

And many felt remorse later.

Professor Pine, of the University of Hertfordshire, said: "Spending was less controlled, more impulsive and more excessive for women in the luteal phase.

"The spending behaviour tends to be a reaction to intense emotions. They are feeling stressed or depressed and are more likely to go shopping to cheer themselves up and using it to regulate their emotions."

Hormonal

She said much of this could be explained by hormonal changes during the menstrual cycle. And the findings were exaggerated in the women with severe PMT.

"We are getting surges and fluctuations in hormones which affect the part of the brain linked to emotions and inhibitory control. So the behaviour we found is not surprising."

Another explanation might be that women are buying items to make themselves feel more attractive - coinciding with the time of the month when they are most fertile.

Most of the purchases made by the women were for adornment, including jewellery, make-up and high heels.

Professor Pine said: "Other researchers have found there is an ornamental effect around the time of ovulation."

Researchers have found women tend to dress to impress during their fertile days.

Professor Pine, author of the book Sheconomics, said if women were worried about their spending behaviour they might avoid going shopping in the week before their period was due.

Africa facing major cancer blight

Africa facing major cancer blight

Breast cancer cell
The rise in cancer is a consequence of people living longer
A major conference is taking place in London to raise awareness about the cancer threat to Africa. The meeting, which is being attended by health ministers from across the continent, will examine the need for cancer programmes across the region.
Cancer is often thought of as a disease of the western world but that is changing fast.
The World Health Organisation says that cancer kills more than HIV/Aids, tuberculosis and malaria combined.
And the International Agency for Research on Cancer calculates annual new cases of cancer are expected to rise from 11m in 2000 to 16m in 2020, of which which some 70% will be in developing countries.
Increased incidence
Speaking before the conference began, the former British health minister Alan Milburn, who is chairing the conference, said the geography of cancer was indeed changing and that a new cancer epidemic was facing Africa.
"In Africa, literally every day, hundreds, possibly thousands of people die needlessly in pain from cancer for want of pain relief that could cost literally pennies rather than pounds.
"The basic infrastructure and resources to cope with the new health epidemic is basically not there and we have to do something about it. We know that there is a steam train that is coming down the track and we have a choice - we can wither, build some new track or we can wait for the train to hit us."
In some parts of Africa, the increased incidence of cancer is a consequence of economic development and populations that are living longer.
But in other parts, where HIV/Aids is slashing longevity, cancer rates may be rising directly as a result of the HIV/Aids epidemic with cancers such as Kaposi's sarcoma, tumours which appear under the surface of the skin or on mucous membranes, becoming increasingly common.
"HIV/Aids lowers the immunity of a patient and you know that throughout your lifetime the immunity keeps things in balance," Dr Mompati Malane, the head of clinical services in Botswana, told the BBC.
"You know you've got those bad cells that will go wrong and then they get eliminated by the immune system.
"But now with with HIV and immunity lowered, these cells are not killed that quickly and therefore it means that the the abnormal cells will multiply and cause cancer. We are seeing a lot of Karposi sarcomas which was not common in the past and this is mainly due to HIV/Aids."
Of course one of the main problems for Africa is funding for treatments.
For example, radiotherapy is only available in 21 countries in Africa.
But what the delegates were keen to stress as the conference began was that batting cancer is not just about expensive facilities.
Screening, early diagnosis and the uptake of inexpensive drugs were equally important, they said.

NHS and social services in England are failing to meet the health needs of people with learning disabilities, investigators say.

The Health Service and Local Government Ombudsmen said the standard of care was an "indictment of our society" after reviewing the deaths of six people.

They found one man died as a result of failings in his care, while a second death could have been avoided.

The government said it was taking steps to address the problems.

The ombudsmen investigated the cases after they were highlighted by the charity Mencap.

CARE LINKED TO DEATH
Mark Cannon - The 30-year-old died eight weeks after being admitted to hospital with a broken leg. He waited three days to see a pain team and developed an infection. Complaints were upheld against the hospital and council - he was in a care home when he was first injured. The ombudsmen ruled care contributed to death.
Martin Ryan - Died several weeks after having stroke. While in hospital, the 43-year-old went 26 days without being fed. The hospital was criticised: death could have been avoided if care had been better.

They looked into complaints made by the families of the six people who died between 2003 and 2005.

The report found failings by hospitals, local health bosses, the official NHS regulator and social care services provided by councils, although none of the complaints against GPs were upheld.

It linked the care of two of the six - Mark Cannon, 30, from Romford, east London, and Martin Ryan, 43, from Richmond, west London - to their eventual deaths.

It also said the failings in the care of two more - Tom Wakefield, 20, from Cheltenham, Gloucestershire, and Ted Hughes, 61, from High Wycombe, Buckinghamshire - was partly due to the fact that they had learning disabilities.

In the final two cases - those of Emma Kemp, 26, from Newbury, Berkshire, and Warren Cox, 30, from St Leonards, East Sussex - the complaints were not upheld, although some aspects of their care were criticised.

The ombudsmen also ruled that investigation of their complaints was flawed, although at different stages in the process.

The investigtors said there was enough evidence to suggest problems were endemic across the services.

'Inadequate care'

Ann Abraham, the Health Service Ombudsman, said: "The recurrence of complaints across different agencies leads us to believe that the quality of care in the NHS and social services for people with learning disabilities is at best patchy and at worst an indictment of our society."

Allan Cannon, father of Mark, said the family had to push at every stage to try to get better treatment.

He said no proper checks were done following Mark's surgery, and it was later discovered he had lost 40% of his blood.

"After the surgery, he was in an awful lot of pain and it just continued. He was being neglected by staff, we were calling for help."

In total, the role played by 20 different bodies in the cases was investigated.

Hospitals were criticised for the inadequate care and treatment given to people with learning disabilities as well as the way they looked into complaints.

POOR CARE BECAUSE OF DISABILITY
Tom Wakefield - The 20-year-old had long history of stomach problems before dying of pneumonia and reflux problems. The council and the NHS were criticised for not planning and providing adequate care. The Healthcare Commission complaint handling was also found at fault.
Ted Hughes - After spending most of his life in care homes, the 61-year-old died the day after being released from hospital after an operation. Discharge arrangements by the hospital were found to be inadequate.

Councils were attacked for failing to provide or secure adequate levels of health care, while local health managers working for primary care trusts were said to be struggling to plan services properly.

The Healthcare Commission, the NHS regulator, was even ruled to have not handled complaints properly in some of the cases.

The ombudsmen said there was sufficient policy and guidance available, but agencies were not following it and, as a result, were in breach of human rights and disability discrimination laws.

They recommended all agencies review the systems they have in place for making sure the needs of people with learning disabilities were met.

Communication

In particular, they said staff needed to improve communication with the patients and their families, and social care and NHS teams had to work together better to ensure discharge arrangements were good enough.

The ombudsmen's report comes after the government has already promised to improve training and carry out a full inquiry into premature deaths among people with learning disabilities.

POOR INVESTIGATION OF COMPLAINT
Emma Kemp - The 26-year-old died shortly after being diagnosed with cancer. Her mother complained she should have been diagnosed earlier and given chemotherapy treatment. The complaint not upheld, but the way it was handled was criticised
Warren Cox - Died 90 minutes after being admitted to hospital with stomach pains. The hospital was found to have acted correctly, but the Healthcare Commission failed to offer them proper review of case

Ministers made the announcements earlier this year after an independent inquiry last year into the deaths found significant failings.

Care services minister Phil Hope said: "Preventable deaths of people with learning disabilities are absolutely unacceptable.

"We are taking action to ensure that people with learning disabilities get the equal access to the health care that they deserve."

But Mencap chief executive Mark Goldring said the findings were "damning".

He said: "We would have liked to see individuals held accountable where they have not met required standards.

"We will continue to fight for justice for the families and, with them, consider referring the individual doctors who failed in their duty of care to the General Medical Council."

Oxford research

 CONCLUSIONS AND RECOMMENDATIONS: Overweight/obesity increases the risk for cancers of the oesophagus (adenocarcinoma), colorectum, breast (postmenopausal), endometrium and kidney; body weight should be maintained in the body mass index range of 18.5-25 kg/m(2), and weight gain in adulthood avoided. Alcohol causes cancers of the oral cavity, pharynx, oesophagus and liver, and a small increase in the risk for breast cancer; if consumed, alcohol intake should not exceed 2 units/d. Aflatoxin in foods causes liver cancer, although its importance in the absence of hepatitis virus infections is not clear; exposure to aflatoxin in foods should be minimised. Chinese-style salted fish increases the risk for nasopharyngeal cancer, particularly if eaten during childhood, and should be eaten only in moderation. Fruits and vegetables probably reduce the risk for cancers of the oral cavity, oesophagus, stomach and colorectum, and diets should include at least 400 g/d of total fruits and vegetables. Preserved meat and red meat probably increase the risk for colorectal cancer; if eaten, consumption of these foods should be moderate. Salt preserved foods and high salt intake probably increase the risk for stomach cancer; overall consumption of salt preserved foods and salt should be moderate. Very hot drinks and foods probably increase the risk for cancers of the oral cavity, pharynx and oesophagus; drinks and foods should not be consumed when they are scalding hot. Physical activity, the main determinant of energy expenditure, reduces the risk for colorectal cancer and probably reduces the risk for breast cancer; regular physical activity should be taken

Eating more vegetables and soya-based products may be as effective at reducing cholesterol as medication.

Researchers in Canada have developed a vegetarian combination diet which they say cuts cholesterol by almost a third in just one month.

The diet includes vegetables, such as broccoli and red peppers; soy milk and soy sausages; oat bran cereal and bread; and fruit and nuts.

The researchers believe the food programme could be a possible drug-free alternative to cutting cholesterol and protecting people from heart disease.

Coronary heart disease kills more than 110,000 people a year in England. A major cause is cholesterol circulating in the bloodstream.

Combination diet

It has been known for many years that individually soy protein, nuts and fibres like oats and barley can cut cholesterol by up to 7%.

Professor David Jenkins and colleagues at the University of Toronto decided to test whether the impact was stronger if these foods were combined.

They drew up a seven-day food plan using foods that are commonly available in supermarkets and health stores.

A typical day on the diet included:

  • A breakfast of soy milk, oat bran cereal with chopped fruit and almonds, oatmeal bread, vegetable-based margarine and jam;

  • a lunch of soy cold cuts, oat bran bread, bean soup and fruit; and

  • A stir-fry dinner with vegetables, tofu, fruit and almonds.

    The researchers put 13 people on the combination diet for a month. They found that their cholesterol levels had dropped by 29% by the end of the period.

    The researchers said the findings suggested the combination diet may be as effective as statins.

    These drugs have been used extensively for 15 years to treat patients with high levels of cholesterol.

    Professor Jenkins said further and larger studies are needed before the diet could be recommended to patients.

    He said: "The take home message right now is that there is hope for a drug-free treatment for some people with high cholesterol.

    "For us, the main feature now is to move this forward into longer-term studies."

    But he added: "This opens up the possibility that diet can be used much more widely to lower blood cholesterol and possibly spare some individuals from having to take drugs."

    The study is published in the journal Metabolism

    why old age abuse

    Care homes need to improve their approach to people with dementia, a report by a firm of health and social care analysts has concluded.

    Laing and Buisson found training was "fragmented and ad-hoc" with a third of homes failing to provide staff with specialist instruction.

    The survey of 6,000 UK care homes also questioned the care provided.

    It said only 57% of home residents affected by dementia were cared for in settings "dedicated" to the condition.

    The figure rose to two thirds once all those who ended up with dementia while in care homes were taken into account.

    The number of people in Britain with dementia is expected to more than double to 1.7m by 2051.

    Ministers have already pledged action, promising to improve services, including those in care homes, in their dementia strategy published earlier this year.

    Laing and Buisson said the care home sector had started to revamp its services, but there were still serious gaps in provision.

    Training was highlighted as a key area that needed addressing, with an estimated 248,000 people in care homes suffering from dementia.

    The research also suggested that the aim of reducing the use of anti-psychotic drugs to sedate dementia patients would increase the need for better services.

    Neil Hunt, chief executive of the Alzheimer's Society, said the findings were a "sad indictment of the current state of dementia care".

    "In less than 15 years there will be a million people living with dementia; we need to gear the whole of the care home sector to delivering good dementia care."

    Concern

    And Stephen Burke, chief executive of Counsel and Care, a charity which represents elderly people with caring needs, said: "This report should give cause for concern."

    He said the Care Quality Commission, the new health watchdog that was being launched in April, needed to make the issue a priority.

    Martin Green, chief executive of English Community Care Association, suggested NHS and social care chiefs were starving the sector of money.

    "Providers suffer from a lack of vision and innovation by commissioning bodies - who tend to commission block contracts at low cost for minimum services.

    "What we need is commissioning that understands the complexity inherent in supporting people with dementia and delivers the resources to develop intensive one-to-one bespoke services."

    Meanwhile, Prince Charles is set to call for more of a focus on dementia in a statement to open the the Alzheimer's Research Trust's annual conference in London later.

    He will say: "Sadly, dementia will have an even greater impact as, in the future, the risk of dementia increases as people live longer, and the emotional, social and economic burden we all will face if this threat is left unchecked will be catastrophic."

    Care services minister Phil Hope said he wanted to see care homes take a more active role in the management and care of people with dementia.

    "The national dementia strategy will improve the quality of care in care homes."

    same confusionmore on report

    A vegetarian diet may help to protect against cancer, a UK study suggests.

    Analysis of data from 52,700 men and women shows that those who did not eat meat had significantly fewer cancers overall than those who did.

    But surprisingly, the researchers also found a higher rate of colorectal cancer - a disease linked with eating red meat - among the vegetarians.

    Writing in the American Journal of Clinical Nutrition the team said the findings were worth looking into.

    Although it is widely recommended that people eat five portions of fruit and vegetables a day to reduce their risk of cancer and other diseases, there is very little evidence looking specifically at a vegetarian diet.

    In the latest study, researchers looked at men and women aged 20 to 89 recruited in the UK in the 1990s.

    They divided participants into meat-eaters, fish-eaters, vegetarians and vegans.

    During follow-up there were fewer cancers than would be expected in the general population - probably because they were a healthier than average group of people.

    But there was a significantly lower incidence of all cancers among the fish-eaters and vegetarians compared with the meat eaters.

    'Confusion'

    For colorectal cancer, however that trend was reversed with vegetarians having a significantly higher incidence of the condition than the other groups.

    The researchers were surprised at the finding, which contradicts previous evidence linking eating lots of red meat with the disease.

    Study leader Professor Tim Key, a Cancer Research UK epidemiologist at the University of Oxford, said no previous study had looked at diet in this way and there had been a lot of confusion about the issue.

    "It's interesting - it suggests there might be some reduction in cancers in vegetarians and fish-eaters and we need to look carefully at that."

    He added: "It doesn't support the idea that vegetarians would have lower rates of colorectal cancer and I think it means we need to think more carefully about how meat fits into it."

    More work is needed to unpick the links between diet and cancer but such studies are incredibly hard to do, he said.

    Dr Joanne Lunn, a senior nutrition scientist at the British Nutrition Foundation, said the findings highlight the fact that cancer is a complex disease and many different lifestyle factors play a part in determining a person's risk.

    "An interesting observation was that the vegetarians had a higher rate of colorectal cancer than the meat-eaters.

    "When you look at the detail of their diets, the meat-eaters, to which the vegetarians in this group were compared, are eating only moderate amounts of meat each day - well within the recommendations.

    "Both groups are also just about meeting the recommendation to eat at least 5 portions of fruits and vegetables a day."
