When people get old, their immunity will decline and they will suffer from various diseases, among which Alzheimer's disease is a disease that needs attention. Alzheimer's disease is not only painful, but also brings trouble to children. Therefore, it is particularly important to prevent Alzheimer's disease every day, especially when dementia symptoms appear. So what food can help prevent Alzheimer's disease? Here I will introduce four kinds of foods to help prevent Alzheimer's disease and alleviate the occurrence of dementia.

The first kind of walnut

Walnut is a nutritious food for many middle-aged and elderly people, because it is rich in unsaturated fatty acids, also called linoleic acid, which can be absorbed by the human body and become a component of brain cells. It is a good helper to keep the brain young and help to prevent Alzheimer's disease. Usually you can eat more walnuts, or you can use walnuts to cook porridge and grind soybean milk.

The second kind of pumpkin

Pumpkin is rich in antioxidant components such as β-carotene, vitamin C, vitamin E, and also rich in dietary fiber, which helps the human body to improve immunity, delay aging, and is of great benefit to cerebrovascular diseases. Moreover, pumpkin also contains more zinc, which can keep people's memory, help people develop their brains and make it difficult for people to forget things. These are all good things to fight against Alzheimer's disease.

The third kind of corn

Corn germ is rich in unsaturated fatty acids such as linoleic acid, which can protect cerebral vessels, reduce blood lipids and help promote brain cell metabolism. Eating some corn, especially fresh corn, has the function of strengthening the brain. Corn also contains more glutamic acid and vitamin B6. Glutamate can promote the metabolism of brain cells and prevent memory loss. Vitamin B6 can improve neurological function and reduce the occurrence of Alzheimer's disease. Moreover, the cellulose in corn can adsorb and promote the excretion of carcinogens from the intestine. Eating corn often has many benefits.

The fourth kind of kelp

Kelp is not only easy to obtain and buy, but also rich in nutrition. In addition to the well-known mineral iodine, it also contains unsaturated fatty acids, which helps to prevent memory loss. If eaten in moderation, it will be good for the brain. Kelp is very common to people in coastal areas. Usually kelp silk can be eaten cold or stewed with kelp, and the effect is very good.

In addition, as you get older, you should avoid excessive drinking and smoking. Excessive drinking can lead to liver dysfunction and abnormal brain operation. Moreover, smoking can also lead to cerebrovascular dementia, which is also the main cause of dangerous diseases such as myocardial infarction.
