The power of older people affecting their mental
Posted: January 1, 2012 24:34 AM PST
Older people whose blood contains high levels of certain vitamins and omega 3 fatty acids have better memory and mental abilities than those eating foods with low nutritional value, according to a study published Wednesday, December 28 in the journal Neurology, the journal Medical American Academy of Neurology.
The study also shows that older people consuming these vitamins and omega 3 fatty acids did not know to reduce the volume of their brain, a typical phenomenon observed in people with Alzheimer's.
FRUITS, VEGETABLES AND FISH
This study, one of the first of its kind, specifically designed to measure blood levels of a wide range of nutrients instead of relying on the results of questionnaires on diet, less accurate and less reliable. The authors found that high levels of vitamins B, C, D and E and omega 3, found primarily in fish, had positive effects on mental health and the rest of the body.
"The vitamins and nutrients you get from eating a wide variety of fruits, vegetables and fish can be measured using biomarkers blood," she notes. "I am convinced that these nutrients have great potential to protect the brain and make it work better," said Maret Traber, Linus Pauling Institute at the University of Oregon.
The study also revealed that the small number of participants whose diet was rich in trans fatty acids, among other abundant in dairy products and fried foods, have performed less well on cognitive tests. In addition, the size of their brain was reduced further.
STOP THE BRAIN VOLUME REDUCTION
Overall, the 104 study subjects aged 87 years on average had a good nutritional diet, but 7% had a deficiency of vitamin B12 and 25% of vitamin D. The researchers tested a total of 30 biomarkers of nutrients in blood http://www.blogger.com/img/blank.gifle participants. In addition, 42 underwent an MRI (magnetic resonance imaging) to measure the volume of their brains. "The results of this study are based on ordinary people eating different diets common in the United States," said Maret Traber.
"The results of this study have yet to be confirmed by further research but it is very exciting to think that it is possible for people to stop potentially reducing the volume of their brains and stay cognitively fit by adjusting their diet food, "notes Gene Bowman of the University of Oregon as well.
Junk food seriously affects the brain

We already knew that eating too many hamburgers, French fries, donuts, chips or pizza rich in saturated fatty acids was not really ideal for the line (or sperm quality, by the way). But U.S. researchers now associate junk food to Alzheimer's disease. People who eat lots of saturated fatty acids are more likely to experience a dégénaration brain tissue.
The study published in the journal Neurology has addressed hundreds of people over 65. The goal? Analysis of unknown factors on the risk of dementia. Scientists have observed that the brains of subjects who have significant levels of trans fatty acids (a type of saturated acid) in the blood has shrunk. A phenomenon that leads to poor memory, attention problems and language.
By cons, people who follow diets rich in vitamins B, C, D and E have larger brains and better cognitive performance. Omega 3 also have a positive influence on the brain, they improve our ability to solve problems, plan and perform multiple tasks simultaneously. (CD)
