Alzheimer's: Diet 'can stop brain shrinking'
By Helen Briggs Health editor, BBC News websiteA diet rich in vitamins and fish may protect the brain from ageing while junk food has the opposite effect, research suggests.
Elderly people with high blood levels of vitamins and omega 3 fatty acids had less brain shrinkage and better mental performance, a Neurology study found.
Trans fats found in fast foods were linked to lower scores in tests and more shrinkage typical of Alzheimer's.
A UK medical charity has called for more work into diet and dementia risk.
The best current advice is to eat a balanced diet with plenty of fruit and vegetables, not smoke, take regular exercise and keep blood pressure and cholesterol in check, said Alzheimer's Research UK.

The research looked at nutrients in blood, rather than relying on questionnaires to assess a person's diet.
US experts analysed blood samples from 104 healthy people with an average age of 87 who had few known risk factors for Alzheimer's.
They found those who had more vitamin B, C, D and E in their blood performed better in tests of memory and thinking skills. People with high levels of omega 3 fatty acids - found mainly in fish - also had high scores. The poorest scores were found in people who had more trans fats in their blood.
Trans fats are common in processed foods, including cakes, biscuits and fried foods.
The researchers, from Oregon Health and Science University, Portland; Portland VA Medical Center; and Oregon State University, Corvallis, then carried out brain scans on 42 of the participants.
They found individuals with high levels of vitamins and omega 3 in their blood were more likely to have a large brain volume; while those with high levels of trans fat had a smaller total brain volume.
Study author Gene Bowman of Oregon Health and Science University said: "These results need to be confirmed, but obviously it is very exciting to think that people could potentially stop their brains from shrinking and keep them sharp by adjusting their diet."
'Strong potential'Co-author Maret Traber of the Linus Pauling Institute at Oregon State University said: "The vitamins and nutrients you get from eating a wide range of fruits, vegetables and fish can be measured in blood biomarkers.
"I'm a firm believer these nutrients have strong potential to protect your brain and make it work better."
Commenting on the study, Dr Simon Ridley, head of research at Alzheimer's Research UK, said:
"One strength of this research is that it looked at nutrients in people's blood, rather than relying on answers to a questionnaire.
"It's important to note that this study looked at a small group of people with few risk factors for Alzheimer's disease, and did not investigate whether they went on to develop Alzheimer's at a later stage.
"There is a clear need for conclusive evidence about the effect of diet on our risk of Alzheimer's, which can only come from large-scale, long-term studies."

WARNING FROM RAEL: For those who don't use their intelligence at its full capacity, the label "selected by RAEL" on some articles does not mean that I agree with their content or support it. "Selected by RAEL" means that I believe it is important for the people of this planet to know about what people think or do, even when what they think or do is completely stupid and against our philosophy. When I selected articles in the past about stupid Christian fundamentalists in America praying for rain, I am sure no Rael-Science reader was stupid enough to believe that I was supporting praying to change the weather. So, when I select articles which are in favor of drugs, anti-semitic, anti-Jewish, racist, revisionist, or inciting hatred against any group or religion, or any other stupid article, it does not mean that I support them. It just means that it is important for all human beings to know about them. Common sense, which is usually very good among our readers, is good enough to understand that. When, like in the recent articles on drug decriminalization, it is necessary to make it clearer, I add a comment, which in this case was very clear: I support decriminalizing all drugs, as it is stupid to throw depressed and sad people (as only depressed and sad people use drugs) in prison and ruin their life with a criminal record. That does not mean that there is any change to the Message which says clearly that we must not use any drug except for medical purposes. The same applies to the freedom of expression which must be absolute. That does not mean again of course that I agree with anti-Jews, antisemites, racists of any kind or anti-Raelians. But by knowing your enemies or the enemies of your values, you are better equipped to fight them. With love and respect of course, and with the wonderful sentence of the French philosopher Voltaire in mind: "I disapprove of what you say, but I will defend to the death your right to say it".
