With reference to the recent studies carried out on neurology, it was published in the American academy of neurology that showed that eating better and healthy food could be of great help to reduce brain shrinkage that is commonly related to Alzheimer’s disease in elderly people.

“This approach clearly shows the biological and neurological activity that’s associated with actual nutrient levels, both good and bad,” said Maret Traber, a principal investigator at the Linus Pauling Institute and study co-author.

This study was conducted by the researchers at the institute Oregon State University along with scientists at the Oregon Health and Science University in Portland. This research and study was one of its kinds and completely systematic and informative.

The study, carried out among 104 people at an average age of 87, specifically measured a large series of blood nutrient levels instead of basing results on food questionnaires, which are less specific and not as much of trustworthy.

The nutrients and minerals that we get from eating a wide range of fruits, vegetables and fish can be measured in blood biomarkers and are well known for their strong potential to protect the brain and make them better in working.

Vitamins such as B,C,D and E along with other healthy oils that are mostly found in fish  have major  positive effects on the brain that makes the brain work quick in elderly people. On the other hand elderly people who consume Tran’s fats on a higher level such as fried foods, fast foods and other less healthy diet options did not perform better on the cognitive tests.

Researchers found that while age and education affected performance on the cognitive tests, nutrient status accounted for 17 percent of the variation in scores, and 37 percent of the differences in brain volume.

Of those who took part in the study, seven percent showed a vitamin B12 deficiency, and 25 percent did not have enough vitamin D in their systems.

Scientists tested 30 different nutrient biomarkers. In addition, 42 participants had MRI scans to measure their brain volume.

The entire research was based on the average diet of Americans.
