1. Fruits and vegetables Fruits and vegetables (especially tomatoes) can help reduce the risk of prostate cancer. Studies have found that consumption of tomatoes and tomato products can also reduce the incidence of prostate cancer. The main component of tomatoes is lycopene, which is a highly unsaturated fatty acid isomer of beta carotene, the predominant carotenoid in human plasma, with anti-cancer properties. It is one of the most powerful and effective antioxidants, with two times the antioxidant capacity of beta-carotene and 10 times that of vitamin E. To consume more lycopene, it is recommended that you choose cooked or pureed tomatoes. Other foods that contain lycopene include: carrots, watermelon, apricots, guava, papaya and pink grapefruit. Studies have found that those who eat more cruciferous vegetables can reduce the prevalence of prostate cancer. The phytoestrogens in the diet are mainly isoflavones and lignans, which can inhibit the conversion of testosterone to the more biologically active dihydrotestosterone, so phytoestrogen-rich foods can reduce the incidence of prostate cancer by lowering circulating androgen levels. Phytoestrogen-rich and protective foods include legumes, nuts, cereals, berries, such as soybeans, peas, beans, lentils, walnuts, melons, apples, pomegranates, onions, etc. 3, green tea green tea contains a variety of antioxidants, the main component is the role of tea polyphenols and catechin compounds. The antioxidant components of green tea have significant inhibitory effects on a variety of carcinogens, including aflatoxins, benzo(a)pyrene, cigarette carcinogens, amino acid cleavage products and other induced malignant transformation of cells, which help stabilize cell structure and reduce cell damage, which can cause cell carcinogenesis. Therefore, in order to prevent prostate cancer, it is recommended to drink 2 to 3 cups of green tea daily, but it must be noted that the tea should not be too strong. 4. Selenium and vitamin E Supplementation of both selenium and vitamin E can reduce the risk of prostate cancer. Selenium is an important antioxidant that has anti-cancer effects and can reduce the incidence of prostate cancer by up to 70%, so more intake can be appropriate. Dietary selenium is mainly found in foods such as seafood, cereals, mushrooms, nuts and asparagus. Vitamin E is a family of natural fat-soluble vitamins whose main role is to act as an antioxidant in cell membranes. The most active form of vitamin E is alpha tocopherol, which can be responsible for a 32% reduction in the incidence of prostate cancer. Foods rich in vitamin E are: cereals, nuts, vegetable oils, cod liver oil and green leafy vegetables such as soybeans, peanuts, walnuts, melon seeds, sesame seeds, walnuts, eggs, peanut rice, egg yolks, corn and yellow green vegetables (lettuce, cabbage, etc.). 5, red wine The resveratrol in red wine has anti-cancer effects, resveratrol is a natural grape skin and red wine contains plant antibiotics, with antioxidant, anti-platelet agglutination, anti-atherosclerosis, immunomodulation, estrogen-like growth promotion and other effects for tumor prevention. Studies have found that: each additional glass of red wine per week can reduce the relative risk of prostate cancer by 6%, so it is recommended to drink red wine in moderation.
