Did you know that carrots are one of the “six friends in vegetable production?†The six friends in the vegetable include carrots, pumpkins, tomatoes, bitter gourds, garlic, and black fungus. Because carrots have many health care functions for the human body, Li Shizhen called it "the king of vegetables." The following describes the health benefits of carrots. 1. Good health and longevity: Carrots have the effect of lowering gas and expecting breath, removing phlegm, eliminating food and removing swelling. Experiments have shown that α-carotene is 10 times more potent than β-carotene in inhibiting tumor cells, and it is very effective in preventing abnormal changes in DNA (deoxyribonucleic acid). As early as ten years ago, studies have found that the higher the concentration of alpha-carotene in the blood, the lower the risk of heart disease in the subject. According to a 14-year follow-up survey by researchers at the US Centers for Disease Control and Prevention, it has been found that people with higher blood levels of α-carotene have a longer lifespan. The food with the highest content of α-carotene is carrot. In pumpkin, orange, and citrus, the content of α-carotene is also high. Alpha-carotene is not afraid of high-temperature cooking, put the carrot in the broth, as long as the soup can drink, it will not cause significant loss of α-carotene. On the contrary, cooked food is more beneficial to the absorption of various carotenoids, as long as a small amount of oil can achieve sufficient absorption. 2. To prevent vascular sclerosis, lower blood pressure and reduce heart disease: Carotene contains quercetin, kaempferol can increase coronary blood flow, lower blood lipids, promote the synthesis of adrenaline, which has the role of blood pressure heart. Carrots contain potassium succinate, which helps prevent hardening of the blood vessels, lowers cholesterol, and lowers blood pressure. Folate in carrots can reduce the incidence of coronary heart disease. High blood pressure drink carrot juice, there is a good antihypertensive effect. For those who eat more carrots, the number of heart attacks is almost 50% lower than those who eat fewer carrots. 3. Enhance immune function: Carotene can be converted into vitamin A in the body, which helps to enhance the body's immune function and plays an important role in the prevention of epithelial cell canceration. Lignin in carrots can also increase immunity and indirectly eliminate cancer cells. 4. Yigan Mingmu: Carrots contain vitamin A and beta carotene, which have the ability to promote the formation of photo Pigments in the eye, and can prevent night blindness, strengthen the ability of the eyes to identify color, but also reduce eye fatigue and dry eyes. 5. Contraint: Carrots contain plant fibers, strong water absorption, easy to expand in the intestinal tract, is the "filling material" in the intestine, can strengthen the peristalsis of the intestine, and thus prevent cancer. 6. Anti-allergic: Japanese scientists have found that beta-carotene in carrots can effectively prevent allergic diseases such as pollen allergies and allergic dermatitis, and beta-carotene can regulate intracellular balance, making the body less prone to allergic reactions. 7. Beautiful face: A German study showed that carrots contain the antioxidant carotene, and those with high concentrations of antioxidants in the skin have significantly fewer wrinkles than those with low concentrations of antioxidants in the skin. 8. Prevent colds: Carrots contain a highly immunogenic substance, lignin, which increases the ability of the body's macrophages to reduce colds.
