First, eat more foods rich in carrots. Eating foods rich in carotene in daily life is helpful to enhance the ovulation function of ovaries. Common carotene foods include spinach, carrots, leeks, rapeseed, shepherd's purse, Malantou and so on. Studies have shown that women who often eat carrots are 50% less likely to develop ovarian cancer than ordinary women, which shows the efficacy of carotene. Therefore, women who need to delay aging and maintain their ovaries should eat more foods rich in carotene. Second, eat more foods rich in vitamin C and vitamin E. If the human body supplements 90 mg of vitamin C and 30 mg of vitamin E every day, its ovarian lesion rate can be reduced by 50%. Therefore, we should eat more foods rich in vitamin C and vitamin E in our daily diet, such as green peppers, cucumbers, tomatoes, Chinese cabbage, fresh dates, oranges, broccoli, orange juice, strawberries, etc., which can not only supplement the nutrients needed by the human body, but also play the role of ovarian maintenance. However, it is far from enough to take it simply through food. People who lack such nutrients in the body should be supplemented with vitamin C and vitamin E health care products, so as to achieve the goal of maintaining ovaries quickly and effectively. Third, eating more foods rich in folic acid will help reduce the incidence of ovarian cancer in women. The study found that women who often eat foods rich in folic acid have a 74% lower risk of ovarian cancer than women who seldom eat folic acid. Common foods rich in folic acid are orange juice, walnuts, peanuts, liver, kidney, eggs, beans, etc., which should be eaten for a long time for women who need to maintain their ovaries, so as to play the role of ovarian maintenance. 4. Eating more foods rich in high-quality protein and high-quality protein is the key to maintaining ovaries. Eating foods rich in protein in daily diet can reduce the incidence of ovarian cancer. Everyday common foods such as milk, goat's milk, mare's milk, beef, mutton, pork and dog meat are rich in high-quality protein, which should be taken properly.
