As the population ages, the incidence of dementia and Alzheimer’s disease is increasing. Foreign studies have found that eating fish often can not only make you smarter, but also help to delay Alzheimer’s disease. Moreover, not only fish is good for the brain, almost all seafood is good, the key lies in Omega-3 fatty acids. On the other hand, the study also found that eating fish oil supplements did not have the same effect as eating seafood directly.
Study: Eating seafood 1-3 times a week can delay the course of dementia
The British “Daily Mail” (Daily Mail) reported that experts from Chicago’s Rush University Medical Center (Rush University Medical Center) conducted a study on the brains of 286 patients who recently died of Alzheimer’s disease and found that For people with the disease gene, if they eat seafood for 1-3 meals a week, the degree of brain damage following suffering from Alzheimer’s disease is relatively low. In other words, eating seafood at least once a week may help delay the course of Alzheimer’s disease and reduce the degree of damage to the brain.
Omega-3 fatty acids support brain health, just eat these fish
Researchers believe that Omega-3 fatty acids in seafood are the key. Experts from Alzheimer’s Research UK pointed out that Omega-3 fatty acids can maintain brain health and are an important part of a balanced diet. In terms of fish, mackerel, saury, salmon, tuna, etc. are rich in Omega-3 fatty acids.

On the other hand, the study also found that people who ate fish oil supplements instead of seafood did not get the same effect. There is currently insufficient evidence that fish oil supplements can prevent dementia. The study has been published in the Journal of the American Medical Association (JAMA).
Fresh mercury pollution hurts the brain?Selenium May Help Offset
In fact, researchers were worried that seafood would be bad for Alzheimer’s patients because seafood is easily contaminated with mercury, which might damage the brain’s nerves. But the new study found that people who regularly ate seafood had higher levels of mercury in their brains, but showed no signs of brain damage. Researchers believe that the toxicity of mercury may be reduced by the mineral “selenium” in seafood.
Maintain a healthy lifestyle and reduce the risk of dementia
The causes of dementia are quite complex, including factors such as age, genes, and lifestyle. The best known way to reduce the risk of dementia is to protect heart health, get enough exercise, eat a balanced diet, not smoke, and properly control blood pressure and cholesterol.
The results of the new study are encouraging for older adults with the Alzheimer’s gene, but the small size of the study warrants further investigation. In addition, whether the rule of “ingestion of seafood can reduce brain damage” is applicable to the general public still needs more research to confirm.
