Eating high-protein foods before exams can enhance memory, such as fish, shrimp, meat, eggs, milk and other foods with high protein content, and eating more low-fat foods.

Soybeans and bean products contain about 40% high-quality protein, which is equivalent to eggs and milk. At the same time, they also contain more lecithin, calcium, iron, vitamin B 1, vitamin B2 and so on, and are ideal brain-nourishing foods.

Dietary taboo

1, people who are used to eating salty food will not only cause hypertension, arteriosclerosis and other symptoms, but also damage arterial blood vessels, affect the blood supply of brain tissue, and make brain cells in a state of ischemia and hypoxia for a long time, thus leading to mental retardation, memory decline and even premature aging.

2. Too high lead content in food will damage the brain and cause mental retardation. Foods include: popcorn and preserved eggs contain lead oxide and lead salt, and lead has strong permeability.

3, aluminum-containing food will lead to memory loss and slow thinking ability, so breakfast can not be based on fritters. Aluminum pot is often used in cooking, so we should pay attention to increasing aluminum intake when boiling water with aluminum pot.
