The redder the tomato, the more ripe it is. The most effective anti-cancer dish is

. When it comes to tomatoes, many people think of lycopene. The research found that the ability of scavenging free radicals of this phytochemical far exceeds that of vitamin C, carotene and vitamin E. it can effectively protect the body from the damage of oxygen free radicals, and to a certain extent, it can prevent cancer, protect cardiovascular health, delay aging and protect skin. Let’s have a look at it.

tomato varieties, color, size differences, taste, nutritional quality are different, which lycopene content is high? The content of carotene in orange tomato was higher than that in pink tomato. Light yellow tomatoes contain a small amount of carotene, almost no lycopene. Generally speaking, the redder the color of tomato, the higher the maturity, the higher the lycopene content, and the stronger the anticancer activity.

Eat ripe tomatoes in winter to protect your cardiovascular system.

the red, sour and sweet tomatoes are served with golden eggs. This red and yellow home cooked dish is a regular guest on the common people’s table, Tomato is also an indispensable health Guardian all year round.

tomato is rich in vitamins, carotene, calcium, potassium and other minerals. Lycopene is the main pigment of mature tomato, with strong antioxidant activity.

Studies have also shown that eating tomatoes often can prevent prostate cancer, men can eat more.

generally speaking, the higher the maturity of tomato, the higher the lycopene content, and mainly distributed in the water-insoluble part and skin of tomato, accounting for 72% ~ 92% of the total lycopene content in tomato. When eating tomatoes, it’s best to wash them and cook them with skin. In addition, the content of lycopene in guava, watermelon, grapefruit and other fruits was also higher.

Eat 5 kinds of recognized anti-cancer vegetables

asparagus & mdash& mdash; Asparagus is rich in tissue protein, folic acid, nucleic acid and selenium. It ranks first among 30 kinds of anticancer plants and is recognized as an anticancer drug by the world. Asparagus enters the lung meridian and kidney meridian to treat lung cancer, renal cell carcinoma, skin cancer, bladder cancer and lymphatic cancer.

Carrot & mdash& mdash; The incidence rate of cancer is 2 times higher than that of normal people due to vitamin A deficiency. Carotene contained in carrot can be transformed into a large amount of vitamin A, therefore, it can effectively prevent the occurrence of lung cancer, and even has the effect of preventing the progress or reversing the transformation of cancer cells. Carrot is rich in folic acid, which is a kind of vitamin B and has anti-cancer effect; The lignin in carrot can also improve the body’s anti-cancer immunity and indirectly kill cancer cells. For long-term smokers, if you can drink half a cup of carrot juice every day, it can also protect the lung.

Spinach & mdash& mdash; Spinach contains a lot of plant crude fiber, which can promote intestinal peristalsis, help defecate and reduce the residence time of carcinogens in the intestine. Moreover, eating spinach can reduce the damage of carcinogens in cooked meat to human cells, reducing the risk of intestinal cancer by half, from 58% to 32%. In addition, spinach is rich in anti cancer beta; Carotene and folic acid. However, due to the high content of oxalic acid in spinach, patients with kidney stones should not eat a lot.

shepherd’s purse & mdash& mdash; Capsella bursa pastoris is rich in protein, fat, food fiber, organic acid, malic acid, minerals, potassium, calcium, magnesium, iron, vitamin C, nicotinic acid and B vitamins. Dithiolone in mustard has anticancer effect; Also rich in vitamin C, is a good anti-cancer food.

corn & mdash& mdash; Selenium and magnesium contained in corn have anti-cancer and anti-cancer effects. Selenium can accelerate the decomposition of peroxides in the body, so that malignant tumors can not get the supply of molecular oxygen and be inhibited. On the one hand, magnesium can inhibit the development of cancer cells, on the other hand, it can promote the excretion of wastes from the body. Corn also contains a & lt; Glutathione & quot; The anti-cancer factor.

Eat four kinds of food to prevent cancer for life

there are more than 100 kinds of common anti-cancer food, which are mainly divided into four categories& ldquo; Eating more anti-cancer food can add to the cake& rdquo; Ma Guansheng, deputy director of the Institute of nutrition and food safety of the Chinese Center for Disease Control and prevention, said.

fresh fruits and vegetables. The antioxidants, carotenoids, vitamin C, flavonoids and other active ingredients in it have anticancer effect. Yang Binghui, a famous health education expert in China and chief physician of internal medicine of Zhongshan Hospital Affiliated to Fudan University, is full of praise for the anti-cancer effect of fruits and vegetables; The risk of gastric cancer can be reduced by 50% if the daily vegetable intake per person is increased from 50g to 300g& rdquo; Asparagus, cabbage, tomato, sweet potato, konjac, kiwi, radish and carrot are all good anti-cancer food.

bean products. Tofu and soybean milk are rich in soy isoflavones. Regular consumption of soy products can reduce the risk of breast cancer, colon cancer and prostate cancer.

fungi. About 96% of the fungi have anti-cancer effect, such as mushroom, Lentinus edodes, Flammulina velutipes, Auricularia auricula and other polysaccharides, which can enhance human immunity and prevent gastric cancer and lung cancer. At present, lentinan has been used as an anticancer drug in the treatment of cancer patients.

green tea. Green tea is rich in tea polyphenols, which can combine with carcinogens to decompose and inhibit the growth of cancer cells. Develop the habit of drinking 2 ~ 3 cups of green tea every day, can prevent gastric cancer, liver cancer and lung cancer, but we must pay attention to, tea is not too thick.

Scientific Cooking: prevention of cancer; Three minus & quot;

after understanding the principles of choosing food materials, it is equally important to learn scientific cooking methods for diet cancer prevention. Even good food can produce a lot of chemical carcinogens after unreasonable cooking, so it’s best to master & lt; Three minus & quot; principle.

to reduce pesticide residues. Chemical fertilizers, pesticides and other residual chemicals are closely related to cancer. In addition to urging the relevant departments to strengthen supervision, we should also pay attention to the following aspects in daily life: prevention of cancer; Slow & quot;

chew slowly to reduce carcinogens. Professor Yang Li of China Academy of Chinese medicine said that human saliva contained peroxidase, catalase and vitamin C, which not only had antioxidant effects, but also could break down entrance carcinogens and effectively reduce the incidence rate of cancer. Studies in the United States have confirmed that when strong carcinogens such as nitrite compounds and aflatoxin encounter saliva, the cellular variability will be completely lost in 30 seconds. From this point of view, the pace of meals should not be too fast, chew slowly to help saliva play anti-cancer effect, a mouthful of food chew 30 times and then swallow the best.

to prevent esophageal cancer. Xun Xiaolin pointed out that people who eat too fast and too fast tend to eat too hot. Over time, the stimulation of high-temperature diet will cause frequent damage of oral mucosa, esophagus and gastric mucosa, and even ulceration and bleeding, thus inducing cancer. Data show that in patients with esophageal cancer, usually like hot food, hot drink accounted for more than 90%. Therefore, eat must slow down, wait for the food to cool down, it is best to 40 degrees Celsius when eating.

controlling food intake can also prevent cancer& ldquo; Only when you eat slowly can you feel the disappearance of hunger and the gradual fullness in your stomach. Then you can put down your chopsticks in time to ensure that you are full& rdquo; Fan Zhihong, associate professor of School of food science and Nutritional Engineering, China Agricultural University, said that if you see a good food, it’s like eating a big meal. It’s often easy to overeat, which brings huge digestive pressure to the gastrointestinal tract. Japanese studies have shown that always eating too much will reduce the activity of inhibiting cancer factors and increase the risk of cancer. So stick to & lt; Slow & quot; The principle of “anti-cancer” is of great benefit to the prevention of cancer.
