What should the elderly eat to strengthen their brains?

When people reach middle age, they will find that their physical strength has declined significantly, their thinking activities are not as agile as before, and brain aging begins.

How does aging happen? Sclerosis of any blood vessels in the brain is the cause of aging. Blood vessels are the pathways that carry nutrients such as glucose and oxygen to the brain. Once they are blocked or ruptured, nutrients cannot be transported to the brain, and Alzheimer's disease and other phenomena will occur.

Cerebral blood vessel occlusion is also called cerebral infarction, and cerebral blood vessel rupture is cerebral hemorrhage, also called stroke. They are all acute cerebrovascular diseases. Generally speaking, acute cerebrovascular diseases are caused by improper diet. In order to prevent these diseases, attention should be paid to the intake of appropriate foods to ensure sufficient and balanced nutrients.

Foods rich in calcium are beneficial to the brain. Calcium calms the mind and dilates blood vessels. Middle-aged and elderly people should eat more milk and dairy products, soybeans and soy products, and seaweed foods, which have a good effect on brain health. B vitamins play an extremely important role in maintaining the normal function of nerves and many enzymes.

Foods rich in B vitamins include: peanuts, tofu, mushrooms, brown rice, green leafy vegetables, wheat germ, etc. Vitamin E is known as a vitamin that prevents and treats aging. It is an important substance that scavenges free radicals in the body and prevents the oxidation of polyunsaturated fatty acids. Free radicals are an important cause of human aging, and vitamin E can remove these "junk".

The oxidation of polyunsaturated fatty acids is also one of the factors that causes cell damage and ultimately leads to aging. Vitamin E can protect polyunsaturated fatty acids from oxidative damage, thereby preventing cell aging. Walnuts, peanuts, animal livers, etc. are rich in vitamin E. In addition, fungi, alkaline foods and fermented foods are also good for brain health.
