DHA contained in fish mainly exists in brain, retina and nerve in human body. DHA can maintain the normal function of retina, especially for infants, and promote the sound development of vision. DHA is also very helpful to the development of human brain and intelligence, and it is also an indispensable nutrient for the growth of nervous system.
2. Walnut, walnut is a good food for nourishing the brain, and is known as "brain gold". Because it is rich in unsaturated fatty acids, it is recognized as a traditional brain-nourishing and intelligence-improving food in China. It is advisable to eat 2-3 walnuts every day, and persevere in order to replenish the brain, enhance memory and eliminate brain fatigue.
3. Peanut is a traditional food that people like to eat in our country, which has certain medicinal value and health care function. Containing 7% polyphenols, its antioxidant capacity is 50 times that of vitamin E, which can effectively delay aging and improve intelligence. Known by the ancients as "ginseng fruit", it is recognized as one of the three intellectual nuts in the world.
Peanut is rich in lecithin and cephalin, which is an important substance needed by nervous system. It can delay the decline of brain function, inhibit platelet aggregation and prevent cerebral thrombosis. Experiments show that eating peanuts regularly can improve blood circulation, enhance memory and delay aging, which is a veritable "longevity fruit".
4. Kiwifruit is the most abundant and comprehensive. The content of vc, mg and trace elements in kiwifruit is the highest, and it is an important nutritional component to maintain cardiovascular health. Among the top three fruits with low sodium and high potassium, kiwifruit ranks first because it is more fragrant and citrus has higher potassium content.
Kiwifruit is rich in vitamin C, which can relieve depression.
Vitamin C also plays a role in the synthesis of neurotransmitters in the brain, which can relieve depression. The ingredients rich in vitamin C are citrus, strawberry, kiwi fruit, guava, bitter gourd and fresh jujube. Milk is an excellent source of high-quality protein, riboflavin, potassium, calcium, phosphorus, vitamin B 12 and vitamin D, which can provide various nutrients for the brain.
Extended data:
Turning the eyeball, British researchers found that turning the eyeball left and right can effectively improve memory. If you want to recall something quickly, just roll your eyes back and forth for 30 seconds, which will produce good results. Researchers believe that the horizontal rotation of the eyeball can make the left and right hemispheres of the brain communicate with each other, which is very important for recalling people's memories. The researchers also found that turning left eye can stimulate the right brain, and turning right eye can stimulate the left brain. The eyeball turns back and forth from left to right, which can improve the correlation between the left and right brains, which is the key to improve memory.
Breathe fresh air. Researchers at the University of Michigan recently found that breathing fresh air outdoors or walking in parks and suburbs can help improve memory. The results show that people who walk in the suburbs have improved their short-term memory by 20%. Researchers believe that the noise and entertainment in the city will stimulate people and affect their memory and attention. Nature can calm people down and help them concentrate.
High-fives and kicks every day, as the saying goes, "High-fives and kicks every day will never make you old", which does have medical basis. The foot is considered as the "second heart" of human beings, with a large number of nerve endings. Therefore, regular kicking can not only help the blood circulation of lower limbs, but also regulate nerve activity, delay aging and improve memory. Methods: Recumbent kicking is more conducive to promoting blood circulation. Hook the foot first, then the calf will feel tight, then straighten the foot, and then the instep will feel sore. Do it alternately for two or three minutes.
Eat more blueberries. Researchers in the United States and Canada recently reported that eating more blueberries rich in anthocyanins can help the elderly improve their memory. The researchers conducted a 12-week study on two groups of elderly people with slightly decreased memory over 70 years old. One group of elderly people drank two to two and a half cups of blueberry juice every day, while the other group drank a placebo drink. After the study, the performance of the old people who drank blueberry juice in learning and memory tests improved significantly, but the control group did not change.
The above research shows that eating more blueberries can slow down nerve degeneration and improve memory. There are blueberry drinks on the market, and the elderly with poor memory can choose them appropriately. Have a good breakfast. A study in Toronto, Canada, found that among men and women aged 6 1~79, people who eat breakfast can get higher scores in the memory score test. Moreover, children who have eaten breakfast do better in exams.
