1, dietary fiber

Dietary fiber is a kind of polysaccharide, which can not be digested and absorbed by gastrointestinal tract and can not produce energy. Therefore, it was once considered as a "non-nutritive substance" and has not been paid enough attention for a long time. Studies by the Nutrition Society show that dietary fiber supplementation can actually play a great role in the human body. It can be described as an important element to clean up human excreta. Dietary fiber expands when it meets water, and its absorption is helpful to increase intestinal peristalsis, promote the excretion of toxins in the body, keep blood vessels clean, and play an important role in the recovery of varicose veins. For example, eating coarse grains and vegetables can supplement dietary fiber.

2. Selenium

Selenium is one of the essential trace elements for human body. Studies have shown that selenium has the functions of scavenging free radicals, eliminating toxins and resisting oxidation, and can effectively inhibit the production of lipid peroxides. Relying on its powerful antioxidant function, selenium can regulate cholesterol and triglycerides in the body, clear cholesterol, reduce blood viscosity, prevent thrombosis, protect blood vessels and prevent varicose veins.

If the selenium level in the body decreases, it will cause the deposition of harmful substances on the blood vessel wall to increase, the blood vessel elasticity to decrease, the blood flow speed to slow down, and it is easy to induce varicose veins. Therefore, seemingly insignificant selenium still has a strong effect on the recovery of varicose veins. To supplement selenium daily, you can eat more of these foods: black sesame, black beans, black peanuts, black rice, seafood, mushrooms, eggs, garlic, ginkgo and so on.
