1, pomegranate juice
It contains a large number of polyphenol flavane compounds, which have antioxidant and anti-atherosclerosis effects. Epidemiological studies show that the intake of fruits and vegetables rich in phenolic compounds is related to the low cancer mortality. Pomegranate juice is a product rich in antioxidants, and the laboratory has been committed to studying its potential to prevent prostate cancer. Because part of tannic acid is extracted from pericarp during industrial processing, commercial pomegranate juice is rich in flavonoids, so it is beneficial to eat pomegranate juice, especially pomegranate juice processed from pericarp.
2. tea
Tea is a widely consumed beverage in the world after water. Green tea, oolong tea and black tea are all made from the leaves of tea trees, because the chemical composition and flavor are different due to different processes. Green tea contains some polyphenol compounds, including several polyphenols and EGCG, which can be safely drunk. A study of 49 patients with solid tumors found that drinking 3.5 ~ 4 cups of green tea three times a day for at least 6 months is easy to tolerate and safe. Epidemiological studies have found that the incidence of prostate cancer in men who often drink green tea is low. Another study found that the incidence of prostate cancer in Asian men who drink a lot of green tea is lower than that in western men.
Step 3: beans
The function of beans and the preventive effect of phytoestrogens contained in them on prostate cancer have always been the focus of research. Most research focuses on two kinds of isoflavones, especially 5,7,45-trihydroxyisoflavones and isoflavone glycosides. Epidemiological studies have found that people whose diet is rich in soy products have a lower incidence of prostate cancer. It is reported that the incidence of prostate cancer among men in China and Japan is lower than that of men born in the United States, and the incidence of prostate cancer among Asian immigrants in the United States is the same as that of Americans. The intake of soy products in the diet may be the reason for the above differences, because the survey found that the average content of soy products in the diet of Asians is 10 times that of the standard American diet, and the intake of isoflavones in Asians is 50mg/d, while that of Americans is only 2 ~ 3 mg/d. According to the survey on the eating habits of American explorers 12395, it was found that they drink more than/kloc every day.
4. Spinach
Spinach has many health functions, such as protecting eyesight and preventing prostate cancer, colon cancer and breast cancer. Prevention of heart disease, stroke and dementia; Lowering blood pressure, resisting infection and promoting bone health. Fresh spinach should be a frequent visitor at the table.
Step 5: carrots
A diet rich in carotenoids can reduce the risk of bladder cancer, cervical cancer, prostate cancer, laryngeal cancer and esophageal cancer. In addition to cancer prevention, the nutrients of carrots can also enhance immunity and promote the health of ears, eyes and stomach.
6. onions (last name)
People who often eat onions have lower mortality rates of prostate cancer, esophageal cancer and coronary heart disease. Onions also contain sulfides that can lower cholesterol and blood pressure and peptides that prevent bone loss. The natural antihistamine quercetin contained in onion can reduce infection and relieve allergic symptoms.
7. Foods rich in boron
Boron is an element widely found in fruits and nuts. Men can reduce the risk of prostate cancer by taking enough boron in their diet. The researchers compared the eating habits of 76 men diagnosed with prostate cancer and 77,565,438+0 healthy men. The results show that the richer boron content in food and drink, the greater the risk of prostate cancer. This protective effect of boron is not affected by other risk factors such as age, smoking, obesity and race. Foods rich in boron include peanuts, apricots, grapes, dried fruits, avocados, red wine and grape juice.
8, tomatoes
Prostate cancer is related to DNA oxidative damage caused by free radicals. Men eat a pot of spaghetti made of tomato sauce every day for more than three weeks, which can greatly reduce the DNA damage and prostate specific antigen (PSA) level in the body. Researchers believe that tomatoes are rich in lycopene, which can counteract the effect of free radicals. The antioxidant activity of lycopene is the strongest among natural carotenoids, which has the functions of protecting genetic material DNA, inhibiting cancer cell proliferation and regulating hormone status. Its anti-prostate cancer effect has been confirmed by a large number of studies. In fact, some plant compounds in a large number of fruits and vegetables have anti-cancer effects, among which lycopene is an important carotenoid, which exists in fruits and vegetables we eat every day. Tomatoes, apricots, guava, watermelon, papaya and red grapes all contain more lycopene, especially in tomatoes. An adult eating 100-200 grams of tomatoes every day can meet the human body's need for lycopene, and cooked tomatoes are more easily absorbed by the human body.
9. a diet rich in vitamin D.
Vitamin d can prevent prostate cancer. Prostate epithelial cells contain vitamin D receptors, and normal vitamin D content in blood can inhibit cancer cells from continuing to differentiate. Therefore, vitamin D deficiency will lead to an increased risk of prostate cancer. As long as the intake of vitamin D in the diet reaches or approaches the recommended level, the risk of prostate cancer is normal. A large number of studies have shown that when the intake of vitamin D exceeds the recommended level, the risk of prostate cancer will not decrease.
