1 spinach
Spinach has a strong antioxidant capacity, which helps to slow down the cognitive impairment and central nervous system damage caused by age. Spinach is a leader in containing antioxidants vitamin C and vitamin E, which is especially beneficial to the elderly. Scientists at the Nutrition Research Center for the Elderly in Boston, USA, recently administered spinach extract to eight elderly women. The results show that the extract has "strong antioxidant activity", which can improve their antioxidant capacity by 20%, equivalent to taking 65,438+250 mg of vitamin C.
Dark green leafy vegetables
The metabolism of food in protein will produce a substance called cysteine, which is harmless to the body, but if the content is too high, it will cause cognitive impairment and heart disease. Moreover, once cysteine is oxidized, it will have toxic and side effects on the arterial wall. Vitamin B6 or B 12 can prevent cysteine-like oxidation, and the vitamin content in dark green leafy vegetables is the highest.
Three salmon
Fish fat contains omega-3 fatty acids, which can protect the nervous system and help strengthen the brain. Studies show that people who eat fish at least once a week, especially salmon, sardines and herring, have a much lower incidence of Alzheimer's disease than those who seldom eat fish. Eating fish also helps to strengthen the activity of nerve cells, thus improving the ability of learning and memory.
Grape juice or wine
Drinking grape juice often is good for prolonging life. Drinking wine properly has the same effect, but because alcohol can paralyze the nerves, grape juice is a better choice. The antioxidant content of grape juice is higher than that of any other fruits and vegetables, and it can improve the transmission ability of nervous system. Besides prolonging life, grape juice can also improve memory in a short time.
5 cups of hot cocoa
Hot cocoa can not only warm the body, but also be effective for strengthening the brain. The content of antioxidants in drinks made of two teaspoons of pure cocoa powder is almost twice that of red wine, three to four times that of green tea and four to five times that of black tea. Antioxidants in cocoa can protect brain cells and prevent neurological disorders.
6 Whole wheat products and brown rice
The best way to enhance the body's nutrient absorption capacity is to eat brown rice. Brown rice contains a variety of vitamins, which is very important for maintaining cognitive ability. Among them, vitamin B6 is the most effective for reducing cysteine level. Americans seldom eat "coarse grains", which is one of the reasons for their insufficient intake of vitamin B6.
