Because fish oil is originally extracted from seafood, fish oil appears in the form of health care products, while seafood appears in the form of food. And there is no scientific basis for fish oil to replenish the brain. The following are excerpts from scientific research:

This paper, published in Journal of American Medical Association, has undergone five years of clinical research. According to the National Institutes of Health, which funded this research, it is the largest and longest-lasting research in this field.

"Contrary to what most people generally believe, we have not seen that omega-3 fatty acids can alleviate the cognitive decline of the elderly." Emily Chew, the author of the above paper and the clinical deputy director of the National Institute of Eye Health, said.

Fish oil contains omega-3 fatty acids. According to experience, people who often eat fish, such as salmon and tuna, can have better eyesight and better heart and brain health than the average person.

However, eating more fish is one thing, and eating fish oil medicine extracted from fish is another. A study on 20 1 1 shows that fish oil nutrition sold over the counter can not improve the brain health of the elderly with congenital heart disease.

The current research involves a common visual loss, called age-related macular degeneration. The average age of the participants was 72 years old, and 58% of them were women.

They were randomly divided into two groups. One group took a placebo and the other group took pills containing omega-3 fatty acids, and then their memory and cognitive abilities were tested before, 2 years after and 4 years after the experiment. The results show that the cognitive ability of the two groups of elderly people has declined to a similar extent after a period of time, which means that taking fish oil has not brought any improvement to the health of the elderly.
