Yesterday's Fipny egg incident broke out, causing people to panic. However, don't stop eating eggs because of this. We can choose eggs with marked origin and valid tracking codes; at the same time, we can maintain a diversified diet and avoid relying on one food source for a long time to reduce the risk of ingestion; if we are worried about inadvertently ingesting residues, we should increase our daily water intake to strengthen kidney metabolism.

Eggs are a very nutritious protein food. Recent studies have found that eating "eggs" in moderation can reduce the risk of Alzheimer's disease by about 47%!

This study is the latest study of the "Memory and Aging Project" funded by the National Institutes of Health and published in The Journal of Nutrition. The project conducted a long-term survey of older adults in the Chicago area and conducted an in-depth analysis of the brain structure of 578 deceased people to evaluate the relationship between their eating habits and Alzheimer's disease.

The study divided participants into four groups according to the frequency of egg intake: less than once a month, 1 to 3 times a month, once a week, and more than 2 times a week. The results showed that those who ate eggs at least once a week had a significantly reduced risk of Alzheimer's disease by 47%.

During brain anatomy analysis, it was also found that the brain lesions related to Alzheimer's disease, such as amyloid deposition and tau protein accumulation, were significantly less in the brains of regular egg eaters.

Researchers speculate that the key reason why eating eggs is related to cognitive health is that eggs are rich in "choline", a nutrient that is extremely important for brain nerve conduction and cell structure maintenance.

Studies have pointed out that subjects who consume more choline can maintain cognitive ability as high as 40%. In addition, the Omega-3 fatty acids in eggs also help inhibit cellular inflammation and further protect brain health.

However, the study also cautioned that although there is a positive association between eggs and the maintenance of cognitive abilities, it is not yet directly proven that eggs can "prevent Alzheimer's disease." The research questionnaire was only conducted once, and it focused on "whole egg intake" and did not mention consumption of other egg dishes. Therefore, it is impossible to know whether eggs prepared in other ways are beneficial.

Researchers suggest that incorporating eggs into your daily diet will not only help improve cognitive performance in language tests, but may also reduce the risk of Alzheimer's-related lesions. It can be said to be the simplest, cheapest and most affordable way to care for your brain.

However, if you develop suspected abnormal symptoms after eating eggs, such as persistent and unknown abdominal pain, vomiting, dizziness, etc., you should seek medical advice as soon as possible and inform the doctor of possible background conditions.
