Food for Senior Three Students to Improve Memory
60% of brain cells are composed of unsaturated fatty acids, the most important of which is dha. DHA is an important component of brain neurons. it is very important for the conduction of brain neuronal components and the growth of synapses. DHA can enhance brain intelligence, memory and concentration.
DHA is almost zero in terrestrial meat and vegetables, and only exists in marine meat, among which deep-sea fish are the most abundant, especially in eye socket fat and skin. However, large deep-sea fishes are located in the upper layer of the food chain. They accumulate too much heavy metals in their bodies. They are not suitable for overconsumption. On the contrary, the autumn saury with higher DHA content than salmon is more suitable.
Compared with fat meat, lean meat has less fat and higher protein content, so its nutritional value is higher. In addition to rich protein, lean meat is also rich in vitamins b, e, and minerals iron and phosphorus. Iron is an important component of hemoglobin in red blood cells. Hemoglobin is a tool for the human body to transport and exchange oxygen. It can keep the brain active. Iron deficiency can cause anemia, mental distraction and memory loss. Phosphorus is a key substance involved in nerve fiber conduction, energy generation and storage, and an indispensable element for brain operation.
The main component of monosodium glutamate is sodium glutamate, which can be converted into glutamate under the action of gastric acid. Glutamic acid is the only amino acid involved in human brain metabolism, which can promote intellectual development, maintain and improve brain function. Regular ingestion of monosodium glutamate is helpful to improve mental retardation and memory impairment. Because monosodium glutamate can increase acetylcholine in the brain, it has a certain effect on neurasthenia.
The vitamin B 1 and B2 in millet were 1.5 and 1 times higher than that in rice, respectively. The protein of millet contained more tryptophan and methionine. Clinical observation found that eating millet can prevent aging. If you often eat millet porridge and millet rice, it will benefit the health of the brain.
Recent studies have found that a large amount of lecithin in tofu is the raw material of acetylcholine to complete brain information transmission. Acetylcholine deficiency is a leading cause of brain retardation and dementia in the elderly.
Eat 1 to 2 meals of tofu per week. Or often drink soymilk.
Soybean contains a lot of plant protein, but it is not very good to digest and absorb. Only when it is made into tofu, the absorptivity can rise to more than 90%.
