Matcha helps prevent cancer due to the presence of EGCG which has chemopreventive properties. Multiple studies have shown that polyphenols present in this tea prevent the proliferation of malignant cancerous cells, and promotes induction of apoptosis. It also assists in reducing the risk of developing various cancers including bladder, colorectal, breast and prostate cancer.
The free radicals created in the body are responsible for corroding the body in various ways, one of which we see as the signs of aging and its related symptoms. Antioxidant-rich green tea neutralizes the oxidants or free radicals present in the body. The catechin polyphenols present in it are hugely responsible for its antioxidizing effects, the most powerful among them being the epigallocatechin gallate. Therefore, regular consumption of green tea can effectively delay the signs and symptoms of aging.
If not taken with sugar, the alkaline nature of green tea helps reduce the blood glucose level. Moreover, the antioxidant and astringent qualities of green tea ensure good health and better functioning of the pancreas. Improving the function of the pancreas means a more efficient and regulated secretion of insulin and the subsequent improvement in decomposing and absorbing of sugar. This increase in effective functions can help prevent the onset of diabetes.
“Specific detox teas offer added benefits in the additional ingredients,” says Villacorta. Herbs like lemongrass, ginger, dandelion, and milk thistle all contain properties said to support a healthy liver, one of those organs in charge of your natural detoxifying process. Ginger has also been proven to alleviate oxidative stress within the liver, which indirectly helps the organ perform its cleaning task more efficiently, he says.
Generally, the leaves undergo an oxidation (often termed "fermentation" in common tea processing terminology). This process produces the distinctive reddish-brown colour of rooibos and enhances the flavour. Unoxidised "green" rooibos is also produced, but the more demanding production process for green rooibos (similar to the method by which green tea is produced) makes it more expensive than traditional rooibos. It carries a malty and slightly grassy flavour somewhat different from its red counterpart.
Flavan-3-ols, the type of flavonoids found in green tea and other teas, provide many of the anti-aging effects of green tea. Catechins in various types of teas are the polyphenols that seem to have the most potent antioxidant effects, according to Natural Standard, the leading and most respected reviewer of herbal compounds. Specific flavan-3-ols found in green tea include monomers (catechins) called:
Grown under shade for three weeks prior to plucking, gyokuro is one of the most exclusive varieties of tea produced in Japan. The shading technique imparts a sweeter flavor, and produces a particularly rich color thanks to the higher amounts of chlorophyll in the shaded leaf. Gyokuro tea is associated with the Uji region, the first tea-growing region in Japan. It is often made using smaller-leaf cultivars of the tea plant.
