Food influence the mental capacity of the elderly

Elderly people whose blood has higher levels of certain vitamins and omega 3 fatty acids maintain their mental capacity and memory longer, a study released on Wednesday.

It found that older people who consume these vitamins and omega 3 fatty acids do not experience a reduction in the volume of his brain, a phenomenon typically observed in people suffering from Alzheimer's.

Published in the Nov. 28 issue of Neurology, the study determined that high levels of vitamin B, C, D and E, as well as omega 3, found mainly in fish, have positive effects on mental health and the rest of the body .

"This approach shows clearly the biological and neurological effects, good and bad, linked to different levels of nutrients in the blood," said Maret Traber, Linus Pauling Institute at Oregon State University, in the northwestern United States.

"The vitamins and nutrients you would get by eating a wide variety of fruits, vegetables and fish can be measured with the aid of blood biomarkers. I am convinced that these nutrients have a great potential to protect the brain and make it work better, "said Traber.

The survey also reveals that the study participants with diets rich in trans fats and acids, abundant in dairy products and fried foods, the results were worse on the cognitive test and showed significant reduction of the brain.

The researchers analyzed 104 individuals with mean age of 87 years, tested with 30 biomarkers of nutrients in the blood. Of this total, 42 also underwent magnetic resonance imaging to measure the volume of their brains.

Healthy diet to maintain brain function and prevent Alzheimer's

Problems with brain function and memory development are closely related to the risk of Alzheimer's disease. Recently, researchers have found a link between a healthy diet with a lower level risk of Alzheimer's disease due to lower levels of brain chemicals and reduces the risk of memory problems.

The study published in Archives of Neurology, aims to determine the effects of a healthy diet on biomarker (chemical indicators) for Alzheimer's disease in the brain. The study explains that a healthy diet for adults without cognitive impairment could eliminate Alzheimer's biomarkers by looking in the disease pre-symptomatic level. While a low fat and wholegrain could prevent Alzheimer's disease for those at risk of Alzheimer's, such as obesity. In addition, the low fat and low glycemic also good for memory performance.

Low saturated fat and low glycemic foods are includes fruit, vegetables but not potatoes, and whole grains like steel cut oats or brown rice. And avoid foods with high saturated fat such as red meat, butter and cheese. Also avoid high glycemic foods such as biscuits, white bread, cakes, white rice, table sugar and soft drinks.
