Those with diets high in a number of vitamins as well as omega 3 fatty acids are not as likely to get the brain shrinkage linked to Alzheimer’s disease than those whose diets aren’t high in these nutrients. According to the research, elderly people with higher amounts of a number of vitamins as well as omega 3 fatty acids within their blood had much better results on mental acuity tests and also less of the brain shrinkage found in Alzheimer’s disease – whereas “junk food” diets resulted in exactly the opposite.
These omega 3 fatty acids as well as vitamin D are found mainly in fish. The B vitamins as well as antioxidants C and E are found mainly in vegetables and fruit. The research also revealed that those that had diets that were high in trans fats were more prone to have brain shrinkage as well as lower scores with the memory and thinking tests than those that had diets that were low in trans fats. Baked goods, prepackaged food, fast food, fried food and also margarine spreads are the main foods that trans fats are found in.
The research involved 104 individuals with an average age of 87 with very few memory and thinking problem risk factors. Blood tests had been made use of to ascertain the amounts of various nutrients within the blood of each person. Each of the participants also took memory and thinking skill tests. Forty two of the people had MRI scans to determine their brain volume.
On the whole, they had good nutritional status, but 7 % were vitamin B12 deficient and 25 % were vitamin D deficient .
The nutrient levels within the blood accounted for a lot of the variation in both brain volume as well as memory and thinking scores. The levels of nutrients accounted for 17% of the score variations for the memory and thinking tests. Other factors like age, amount of years of education as well as hypertension accounted for 46 % of the variation. The levels of nutrients accounted for 37% of the variation for brain volume. The potential to help stop brain shrinkage just by adjusting diet is exciting.
