According to research, nutrition experts point out that, white-collar workers should pay special attention to their diets. Then what foods are the best for white-collars? Let's look at the following five kinds of food, which can invigorate the brain.

1. Peanut
Peanut contains a large number of lecithin and cephalin, which is an important material for the nervous system. It can delay the declining of brain function, inhibit platelet aggregation, and prevent cerebral thrombosis. The experiment proves that, often eating peanuts can improve blood circulation, enhance memory, as well as delay ageing. As a result, it is really a "longevity food".

2. Milk
Milk is a nearly a perfect drink. It is rich in protein, calcium, and a variety of essential amino acids needed by brain. The calcium contained in milk is the most easily absorbed by human body, and it is also an important and indispensable nutrient for the metabolism of brain. In addition, it also contains vitamin B1, which is very beneficial to nerve cells. If the white-collars always suffer from insomnia after heavy work, they can drink a glass of hot milk before going to bed, which can greatly improve their sleep quality.

3. Fish
Fish can provide high-quality protein and calcium to the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which will not cause sclerosis vascularis and has no harm on cerebral artery vessels. Instead, they can even protect the blood vessels of brain, and can promote the activity of brain cells.

4. Corn
Corn germ contains many kinds of unsaturated fatty acids, such as linoleic acid, which has the effect of protecting cerebrovascular and lowering the level of blood fat. What's more, corn is especially rich in glutamic acid, which can promote the metabolism of brain cells. As a result, often eating some corns, especially fresh corns, can greatly improve the function of brain.

5. Pineapple
Pineapple contains a large number of vitamin C and trace element manganese. What's more, it is low in calories. Often eating pineapple can promote the secretion of saliva or body fluid, as well as refresh the brain. As a result, it is one of the best foods for those white-collar workers.

What's more, other foods such as egg, spinach, millet, chili, orange, etc, are also very beneficial to the health of brain. As a result, white-collar workers can eat more of these foods in their daily diets.
