At present, it is clear that oxidation is an important cause of human aging. In order to prevent the oxidation of bad cholesterol (LDL) and keep blood vessels young, we should pay attention to ingesting some foods with antioxidant effects in our daily life.
In the process of preventing the occurrence and development of arteriosclerosis, cerebral hemorrhage, cerebral infarction and heart disease, the most striking thing is that food contains polyphenols and other components with high antioxidant effect.
The following foods can be properly ingested, which is beneficial to health.
1. Red wine As we all know, red wine can prevent arteriosclerosis and dissolve thrombus, and it is rich in polyphenols, which plays a vital role. Red wine is made by crushing grapes with red and purple skins and fermenting them. The darker the color, the more polyphenols. Generally, drinking 1 ~ 2 small cups every day can play a health care role. But don't drink too much or too often.
2. Green tea Green tea contains catechins, which are also a kind of polyphenols. In addition to its high antioxidant effect, it also has the effect of inhibiting the increase of blood cholesterol.
Generally, about 2 grams of green tea is used to brew a cup of tea, and 50-60 mg of catechin can be extracted. Change tea frequently, drink about 8 cups a day, and it is estimated that 500 mg of catechin can achieve considerable results.
In foreign countries, besides drinking green tea, it is also popular to refine green tea into powdered green tea, make dishes, or make cakes and sushi.
3. Sesame Sesame is rich in vitamin E, sesamol and other substances, which has a strong antioxidant effect and can effectively inhibit the oxidation of bad cholesterol into lipid peroxide. It is recommended to take about 3-8 grams a day. Sesame should be taken in time after being fried and ground into powder, and it should not be left in the air for too long, otherwise it will be easy to oxidize and the effect will be obviously reduced. Japanese black sesame seeds imported from China are washed and dried, and processed into a bag of 50- 100g by machine, which is very popular and used in cold dishes and sushi.
4. Tomatoes are rich in nutrients, including β-carotene, vitamins C, E, B6 and potassium. It can increase the elasticity of blood vessels, lower cholesterol and lower blood pressure. The redder and riper tomatoes are, the richer lycopene is, and the antioxidant effect is higher than that of β-carotene. You can also choose a beverage made of tomatoes.
As we all know, selenium-rich seafood has strong antioxidant effect and can decompose lipid peroxide. In sardines, flounder, sea fans and other seafood, the content is relatively high.
When selenium is combined with vitamin E with the same effect, its synergistic effect can be maximized. More efforts should be made in cooking methods and ingredients collocation in the future. In addition, selenium can also prevent aging, such as preventing hair loss, menopausal disorders, cataracts and so on.
