An elementary way to keep the brain healthy into old age

The benefits of seafood, we were told more than once. It seems we hear from childhood: "Eat more fish, it is incredibly useful." Well, specifics lovers can get accurate data. A few days ago, researchers discovered how fish affects our brain.

Everyone has heard that fish is good for the brain. This was known at least 100 years ago, a well-known novelist Pelham Woodhouse, Author of a series of Jeeves and Wooster, wrote:

- How many cans of sardines you eat, Jeeves?

- No one, sir. I do not like sardines.

- So you came up with this striking, ambitious, brilliant plan, is not stimulating your brain by eating fish?

- Yes, sir.

A hundred years ago people did not have even a little convincing evidence that fish is good for the brain. Researchers have tried to find him, but all the evidence were ambiguous even if eating seafood and good for the brain, the mercury content in some fish may have backfire.

A new study, published last week confirmed that the fish is really good for the brain. More precisely, consumption of fish reduces the risk of developing Alzheimer's disease.

Author on March Claire Morris (Martha Clare Morris) of Chicago Medical Center drew attention to the people who have been involved in a long process of study, aging and died in the last 10 years. Scientists have studied the brains of deceased investigated amyloid (senile) plaques, which are hallmarks of the disease Alzheimer's, and used the survey data to determine the diet of these people and learn how they fish ate. Yes, the way imperfect, but it is often only possible.

Here's what the researchers found that people who ate seafood at least once a week had a lower level of development once three different signs of Alzheimer's disease. It looks like a fish counter this genetic mutation.

Bad news for the manufacturers of fish oil supplements, and on its basis... Research has shown that fish oil is of no benefit. You need to have is fish.

This is not the first study, which revealed a positive effect of the use of fish. The authors refer to 13 papers published earlier. All they talk about the appearance of a defense mechanism for those who include in the diet of seafood and polyunsaturated fatty acids: suspended development of cognitive impairment and dementia.

However, only new studies evaluated mercury poisoning risks contained in the fish. Apparently, the overall effect is still positive: you get a lot more good than harm.

The authors also pointed out that when we age, the amount of docosahexaenoic acid, an essential substance for our brain, is reduced. Therefore, older people simply have to eat seafood.

It turns out that 100 years ago, Woodhouse was right: a fish really is food for the brain.
