In today's society, more and more people begin to feel that their memory is getting worse and worse, they often forget things, often out of order, and they can't remember when they are interrupted. In this regard, some foods can play a tonic role.

The first is the ubiquitous milk. Milk is a nearly perfect nutrient. It is rich in protein, calcium and essential amino acids for the brain. Calcium in milk is most easily absorbed by people and is an indispensable and important substance for brain metabolism. In addition, it also contains vitamin B 1 and other elements that are very beneficial to nerve cells. Moreover, a cup of hot milk before going to bed helps to fall asleep and improve the quality of sleep.

The second is an egg. Brain activity function and memory intensity are closely related to acetylcholine content in the brain. Experiments have proved that the beauty of eating chicken is that when lecithin in egg yolk is decomposed by enzymes, it can produce rich acetylcholine, which can reach brain tissue quickly after entering the blood and enhance memory. Studies abroad have confirmed that eating 1 or 2 eggs a day can supply enough choline to the body, which is of great benefit to protecting the brain and improving memory.

The third kind is fish. Fish can provide high-quality protein and calcium for the brain. The fatty acids contained in freshwater fish are mostly unsaturated fatty acids, which will not cause arteriosclerosis and do no harm to cerebral arteries. On the contrary, it can protect cerebral vessels and promote brain cell activity. Fish is also a high-sodium food, which is beneficial to the balance of minerals in human body. Fish provide selenium, iodine and fluorine to human body in a natural way. So, don't worry about absorbing too many trace elements. Salmon contains the most selenium, while river fish contains less than half. Eating100g fish every day can meet the daily demand of human body for iodine, thus preventing thyroid diseases. Magnesium is also indispensable to human body. When magnesium is insufficient in human body, you will feel depressed. At this time, you can make up for the lack of magnesium by eating fish and improve your mood. For students, eating more fish can promote brain activity, learn knowledge quickly and remember it well.

Of course, if you want to keep your memory, remember to read more books, read more newspapers, eat less snacks, sleep more, study hard, think hard, order takeout and exercise well.
