On 17 June 2011, at Charles de Gaulle airport in Paris, France, radioactive cesium of 1,038 becquerels per kilogram was measured in tea leaves imported from Shizuoka Prefecture, Japan as a result of the Fukushima Daiichi nuclear disaster on 11 March, which was more than twice the restricted amount in the European Union of 500 becquerels per kilogram. The government of France announced that they rejected the leaves, which totaled 162 kilograms (357 lb).[34]
This best-selling detox tea has a loyal following, with thousands of reviewers claiming that it helped with excess bloating, daily digestive issues, and ultimately contributed to weight loss when consumed alongside a balanced diet and regular exercise. Made with green tea leaf, matcha green tea, and guarana seed, this tea blend is quite caffeinated — so don't sip it before bedtime. 
• In skin cancer studies, lab animals that were given green tea developed 1/10th as many tumors as animals that were given water. The EGCC in green tea inhibits the production of urokinase, an enzyme that cancer cells need in order to grow. It also seems to stimulate the process of programmed cell death, or apoptosis, in cancer cells. Pair your green tea with these 30 foods that help prevent cancer.
Still, there have been some interesting findings. A 2014 study looked at 25 randomized controlled trials on the link between tea and blood pressure and reported that when people drank tea—especially green tea—for 12 weeks, their blood pressure dropped significantly. A 2011 study reported that drinking green tea appeared to be linked with lower levels of bad LDL cholesterol, but more research is needed. Because matcha is a type of green tea, they may share similar benefits, but there’s not enough research to make that claim.
This is yet another powerful benefit of green tea. Astringent substances trigger contractions in muscles and tissues while toning up muscles and skin. Even if you do not wish to drink green tea, a simple, daily mouthwash with it can cause sufficient contraction in your gums to keep them firm and tight on the teeth, thus preventing loosening and loss of teeth. You can also wash your hair with green tea and feel it grow stronger and healthier every day.

Shade grown: All matcha is made from shade-grown tea leaves—a labor-intensive process where tea bushes are protected from the sun and light is filtered to the bushes in a very controlled manor. Shading boosts the chlorophyll production in the plant, giving the leaves a rich green color. The lack of sun reduces the plant’s photosynthesis of the leaves, which in turn alters the naturally occurring levels of caffeine, flavanols, sugars, antioxidants, and theanine. By controlling the sun exposure, tea producers can significantly alter the chemical make-up and flavor of the final tea leaves.
