Wild blueberries are rich in antioxidant vitamins and β-carotene, which can protect body tissues from free radicals and thus slow down aging. ?
2. Improve eyesight and memory.
Wild blueberries, because of their deep and full color, represent high antioxidant content, which is good for memory and eye health.
Blueberry anthocyanin can promote the synthesis of rhodopsin on retina, thus enhancing vision. Blueberries can also promote eye blood flow, improve circulation, relax peripheral nerves and muscles, and eliminate eye fatigue. While promoting blood microcirculation, more nutrients are fully supplied to the eyes, so as to avoid the problems of eye structure deformation and atrophy caused by insufficient blood supply and achieve the purpose of protecting the eyes.
3. Improve insulin sensitivity
Sweet and sour blueberry juice is helpful to improve the sensitivity of insulin, which is beneficial to the health of adults who are overweight and have higher blood sugar than normal (called pre-diabetes). ?
4. Prevention of hypertension
Blueberries are rich in anthocyanins, which belong to flavonoids and have the effect of lowering blood pressure. It is found that people can ingest flavonoids from different sources, but blueberry rich in anthocyanins has the most significant antihypertensive effect, and strawberry rich in anthocyanins also has a good antihypertensive effect. ?
5. Relieve postpartum depression
Protein called MAO-A will increase in women's brain after delivery, which can decompose three pleasant chemicals-serotonin, norepinephrine and dopamine, making people feel depressed. The level of MAO-A reached the highest on the 5th day after delivery, and it was at this time that the new mother's mood was the lowest. Blueberries contain a lot of tryptophan and tyrosine, which can make up for this problem.
6. Strengthen and replenish the brain
Blueberries are rich in antioxidant and anti-inflammatory components, and the chemicals in blueberries help to increase brain blood flow, thereby increasing oxygen input to the brain and enhancing brain function.
Extended data:
Eat blueberries in moderation: Researchers at Kansas State University found that fruits and vegetables such as sweet potatoes, blueberries and broccoli have obvious antioxidant effects, but excessive consumption is harmful to muscle health.
Sweet potato, blueberry, cauliflower and other fruits and vegetables are called "super food" because of their obvious antioxidant effect, which is favored by people. However, the latest research in the United States shows that even the best food should not be eaten in excess, otherwise it will have a negative impact on health. The results of this study are published in the monthly journal of applied physiology.
Harmful to muscles
Researchers at Kansas State University in the United States found that patients who used antioxidant therapy to treat heart disease would find it difficult to walk and their muscles were sore and stiff. This situation also exists in some healthy people. The researchers tested antioxidants on animals. The results show that excessive intake of antioxidants is harmful to muscle function.
"Now we know that antioxidants will consume naturally occurring vasodilators, destroy the body's ability to deliver oxygen to muscles, and make muscles unable to work normally," the British "Daily Mail" quoted researcher Steven Kopp as saying on the 28th.
The experimental results show that excessive intake of antioxidants may destroy the delicate nutritional balance of human body. Because excessive antioxidants will lead to insufficient pro-oxidants. The role of antioxidants is to slow down the loss of muscles and other organs caused by oxidation reaction, while the role of promoting oxidation is the opposite.
Therefore, although nutritionists believe that dementia patients should eat more antioxidant foods, for the elderly, if they eat too many antioxidants, they will "remove" substances that help blood vessels dilate and hinder the flow of blood cells, thus causing breathing problems and making them unable to stay healthy through physical exercise.
