Consuming a diet that is reach in omega-3 like those found in oily fish like salmon may help protect you from memory problems and premature aging. This was according to a study recently published in Neurology, a journal of medicine.
Fish has been known to be a good brain food but the new study is the first research to link levels of omega-3 in the blood with the shrinkage of the brain, decline in brain function, and memory loss which sums up to a higher risk in acquiring Alzheimer’s and other forms of dementia.
The study involved 1,575 individuals who underwent several brain function tests, brain scans, and blood workup. Other factors were taken into consideration like age, education, gender, smoking, among others.
The human brain naturally declines in size and function with age but participants of the study who had lower levels of omega-3 had a brain volume which is similar to people who are two years older than them. The cognitive tests done with this group also resulted to scores showing that their brain function is similar to people who are three years older.
People with lower levels of omega-3 also showed higher amounts of white matter in their brains. The increased volume of white matter predisposes one to stroke and dementia.
The study though does not mean that we have to gobble up on fish and supplements with fish oil. The research was not designed to make clinical recommendations.
Government guidelines suggest around 8 ounces of seafood every week to help prevent heart problems. Walnuts and flax seeds are also great sources of omega-3.
Experts also want to point out that a good heart means a good brain.
