Researchers have found that if ingested in particular, it affects the brain healthy With beneficial nutrients, the probability of suffering from Alzheimer's disease will be 40% lower than that of normal people. Researchers at Columbia University in New York studied 2,148 healthy people over the age of 65.

　　They were required to provide a daily diet list, undergo Alzheimer's testing every one and a half years, and were followed for an average of four years. Of these, 253 developed Alzheimer's disease during the study period. Research results show that people who are less susceptible to the disease tend to consume more salad dressings made with olive oil, nuts, fish, tomato , poultry, cruciferous vegetables, fruits, and dark leafy green vegetables； They eat less red meat, organ meats or high-fat dairy products.

　　Researchers say there may be two reasons why this eating habit works.
