Foods that can soften blood vessels include oat, black sesame, sweet potato, garlic, onion, Chinese cabbage, tofu, tremella, soybean milk, celery, cucumber, chrysanthemum tea and so on. The following experts from Lanzhou Ruijing Diabetes Hospital introduce several kinds in detail: Yam: Mucin contained in yam can prevent the fat deposition of cardiovascular diseases, protect the elasticity of blood vessels and prevent the premature occurrence of atherosclerosis. Auricularia auricula: China's average life expectancy has been in the forefront of the world, and there are auricularia auricula in the chief health diet. Lecithin contained in Auricularia auricula has good emulsification, which can prevent cholesterol from depositing on the inner wall of blood vessels and remove some deposits, and has the function of preventing cardiovascular diseases. Auricularia auricula is often eaten with garlic and onion, which can relieve coronary atherosclerosis. Contains auricularia auricula polysaccharide, which has antithrombotic effect and protects normal blood vessels. Carrots: Folic acid in carrots can reduce the risk factors of coronary heart disease when ingested into human body. Carrots contain β-carotene, which has important physiological significance, can prevent arteriosclerosis, thrombosis and tumor, and can improve human immunity. Carrots contain calcium pectate, which reacts with bile acid and is excreted from feces. If the human body wants to produce bile acids, it will inevitably use cholesterol in the blood, thus promoting the reduction of cholesterol levels in the blood. Carrots contain dermatan, which can improve microvascular function, increase coronary blood flow, reduce blood lipid, lower blood pressure and strengthen heart. American scientists have confirmed that eating three carrots a day can help prevent heart disease and tumors. Wine: proanthocyanidins pectin in wine can lower blood cholesterol; Wine can increase the concentration of high density lipoprotein in blood and help prevent arteriosclerosis; Wine is rich in vitamin P and flavonoids, which can reduce the brittleness and permeability of capillaries and maintain their normal elasticity and physiological functions. Green tea: Green tea is one of the "top ten healthy foods" evaluated by nutrition experts. Flavonols in tea can obviously reduce the contents of total blood lipids, cholesterol and phospholipids in animals. It can make the range of arteriosclerosis smaller and the thickness thinner. Vitamin E and selenium contained in tea have the effects of scavenging free radicals and resisting lipid peroxidation. Selenium can stimulate the repair speed of damaged blood vessels and destroy cholesterol deposited on the damaged inner wall of arterial blood vessels. Corn: The world calls it "medicine bead". Contains linoleic acid and vitamin E, which can prevent arteriosclerosis; Its unsaturated fatty acids (50% of which are linoleic acid) can reduce serum cholesterol; Vitamin e in corn can block the chain reaction of free radicals; Selenium in corn has the functions of scavenging free radicals, resisting lipid oxidation and preventing arteriosclerosis. Soybean: Soybean is one of the healthy foods announced by the World Health Organization. Phospholipids in soybean can remove cholesterol attached to blood vessel wall and maintain blood vessel softening; Unsaturated fatty acids of soybean can reduce the deposition of cholesterol on arteries and develop atherosclerosis; Soybean contains flavonoids, which can regulate the fragility and permeability of capillaries and protect blood vessels. However, moderate consumption of soybeans is beneficial, while excessive consumption is counterproductive. In the health food published by the World Health Organization, kiwi fruit, watermelon, strawberry, orange, orange, walnut, pine nuts, etc. are selected, and these fruits have the function of softening blood vessels. In addition, hawthorn, Rosa roxburghii, apple, banana, lemon, peach, grape, sweet orange, grapefruit, ginkgo, lotus seed and Rosa laevigata all have the function of softening blood vessels. There are also foods with homology of medicine and food, such as Polygonatum sibiricum, jujube, hemp seed, cassia seed, Sophora japonica, Gardenia, mulberry leaves and malt. I hope my answer can help you.
