If seafood appears on your table at least twice a week, you are not only satisfying your appetite and taste, but increasing the mental capacity as well. Specifically, people who eat at least one serving of seafood a week are less likely to develop dementia later in life. Dementia comes from the death of nerve cells and subsequent loss of brain function. The researchers found that highly educated people have figured out that puzzle long time ago.

The researchers analyzed diets of 1,672 dementia-free senior citizens over the course of seven years checking up on the subjects' mental capacities. The study concluded that people who ate at least one serving of fish a week had a 30 percent lower risk of developing dementian than those who followed a diet relatively low in fish.

This may be due to the fact that polyunsaturated fatty acids in fish reduce inflammation in the brain and may aid neural regeneration. Scientists also discovered that dementia occurs less often among highly educated people. The interesting theory here is that exercising brain with complicated tasks practiced by educated people is not the only reason; more highly educated people tend to eat more fish, both because they can afford it and because they are more likely to follow dietary recommendations.

In addition to the list of fishy benefits, a number of respectable studies indicate that eating several servings of fish each week may strengthen your immune system response, assist in blood clot formation and hormone production, balance your cholesterol levels, support healthy brain and nerve function, minimize the risk of cardiovascular disease and stroke, lessen chances of depression, reduce joint and muscle pain associated with physical activity and age, and, of course, add delicious variability to your menu.
