茶多酚EGCG

很多人都知道茶叶可防癌，

茶多酚中的主要成分EGCG

几乎是很多癌症的“克星”，

特别是对子宫癌、皮肤癌、肺癌、结肠癌、

前列腺癌、肝癌、肾癌、乳腺癌等有独特疗效。

但不同的茶类，

抗癌效果也大相径庭。

科学家曾用1.25g绿茶加100mL沸水的茶汤作为小鼠的唯一饮料，可使化学致癌物诱导的小鼠肺肿瘤减少36%～44%，使肿瘤的繁殖降低44%～60%。红茶也具有同样效果。

此外，用绿茶或红茶处理动物可使实验动物的食道癌、胃癌或皮肤癌减少70%。

茶叶的品种不同，抗癌防癌的效果也是大相径庭的，有研究表明，发酵类的茶比不发酵的茶具有更多的抗癌防癌的效果。

茶为什能抗癌？

首先，茶多酚中的EGCG具有抗氧化的活性。

其次，EGCG抑制对肿瘤具有促发作用的酶类的活性。这些酶类包括蛋白质激酶C、鸟氨酸脱羧酶、环氧合酶和脂氧合酶等。

第三，茶多酚可促进具抗癌活性的酶的活性。这些酶类包括过氧化氢酶、谷胱甘肽-S转移酶等。

第四，可以抵抗肿瘤增殖的活性。

第五，经常饮茶的人可以增强免疫性。

Many people know that tea can prevent cancer,

The main component of tea polyphenols is EGCG

Almost the "nemesis" of many cancers,

Especially for uterine cancer, skin cancer, lung cancer, colon cancer,

Prostate cancer, liver cancer, kidney cancer, breast cancer, etc. have unique curative effect.

But different types of tea,

Anticancer effects also vary widely.

Scientists have used 1.25g of green tea plus 100mL of boiling water as the only beverage for mice, which can reduce lung tumors induced by chemical carcinogens by 36% to 44%, and reduce tumor reproduction by 44% to 60%. Black tea has the same effect.

In addition, treating animals with green or black tea reduced esophageal, gastric or skin cancers by 70 percent in laboratory animals.

Different varieties of tea have different anti-cancer and anti-cancer effects. Studies have shown that fermented tea has more anti-cancer and anti-cancer effects than non-fermented tea.

Why can tea fight cancer?

First, EGCG in tea polyphenols has antioxidant activity.

Second, EGCG inhibits the activity of enzymes that are tumor-promoting. These enzymes include protein kinase C, ornithine decarboxylase, cyclooxygenase, and lipoxygenase, among others.

Third, tea polyphenols can promote the activity of enzymes with anticancer activity. These enzymes include catalase, glutathione-S transferase, and the like.

Fourth, the activity against tumor proliferation.

Fifth, people who drink tea regularly can enhance immunity.
