What tea to drink to prevent cancer
1. The anti-cancer effect of green tea some studies at home and abroad have proved that no matter what kind of tea, it has different degrees of prevention and treatment effect on chemical carcinogenesis or metastatic tumor of experimental animals. Both endogenous and exogenous free radicals have carcinogenic effects, but natural antioxidants can scavenge free radicals, so the anti-cancer and anti-cancer effects of natural antioxidants have attracted people's attention. Green tea is rich in "tea polyphenols" and other natural antioxidants. When you drink it before or after meals, many antioxidants will work together to eliminate free radicals, which can show the anti-cancer and anti-cancer effects of green tea.
2. The anti-cancer effect of Pu'er tea after comparing the efficacy of many kinds of green tea, it was found that Pu'er tea had a strong effect on killing and reducing cancer cells. After long-term drinking of Pu'er tea, cancer cells contracted and became round, pseudopodia reduced, lost the ability of attachment and walking, even fell off and floated; The remnant also became smaller, rounded, condensed, nuclear pyknosis, chromatin condensation or disappearance, vacuoles appeared in nucleus and plasma, nucleolus pyknosis or fragmentation disappeared, chromosome spasm or mutual condensation, ribosome decreased, mitochondria and endoplasmic class expanded; RNA synthesis decreased, nuclear division stopped. These changes show that cancer cells tend to die from degeneration under the pharmacological action of Pu'er tea.
Drinking green tea can prevent skin cancer. Researchers at Dartmouth Medical School in New Hampshire found that drinking a few cups of tea a day can reduce the risk of two common skin cancers. After studying the eating habits and health of 2200 adults, a team led by Judy Reese of the college found that tea drinkers had a lower risk of developing squamous cell carcinoma and basal cell carcinoma, two common skin cancers, Reuters reported. People who drink more than one cup of tea a day are 20% to 30% less likely to develop both cancers than people who don't drink tea. Studies have shown that tea contains an antioxidant called EGCG, which can limit the damage to skin caused by ultraviolet radiation. The effect is even more pronounced in people who have been drinking tea for decades and at least two cups a day.
matters needing attention
According to recent studies, whether drinking black tea or green tea, can prevent prostate cancer, but also help lower cholesterol, reduce cell damage caused by smoking, and even prevent heart disease. Foreign researchers investigated 20 male patients with prostate cancer. They drank five cups of green tea and black tea every day before the operation. After the operation, they analyzed their blood samples and prostate tissue and found that the content of phenols in their tissue samples was higher. After adding black tea, green tea or soda into the culture medium of cancer cells, they found that the growth rate of cancer cells was significantly slowed down.
