The Alzheimer's Society commented that "this study adds to previous research that suggests green tea might help to reduce the risk of Alzheimer's disease. However, the researchers used a far higher dose of the active green tea chemical than would ever be found in the human body. More research is needed to see whether green tea is protective at a much lower dose, and to understand the mechanism involved."
All that being said, it should come as no surprise that I fell victim to the active marketing campaigns of one of the year’s biggest trends: fitness teas. You know what I’m talking about: stars and influencers like Kylie Jenner, Catherine Giudici Lowe, and Vanessa Hudgens are touting the successes of their respective experiences with fitness teas. These teas (by various brands) claim to eliminate bloat, cleanse your insides, and detoxify your organs. They claim to help you lose weight and curb cravings. Seriously? I thought as I scrolled through ad after ad. Sign. Me. Up.
We’re wary of any trend that involves detoxing with just a drink. By now, we’re all pretty aware that liquid diets can’t sustain our active bodies for very long, and most of the drinks celebrities swear by have little actual detoxifying effects. But a teatox, or tea detox or tea cleanse, is a gentler approach to the whole idea, namely because it involves adding a few herbal cups to your existing, healthy diet—instead of replacing meals entirely.
Every day, countless people throw away valuable antioxidants and minerals. While seemingly unimaginable, that’s exactly what happens when you brew a cup of green tea because water can only extract a fraction of green teas benefits. The majority actually remains unused, trapped in the tea leaves. In reality, the only way to truly take advantage of green teas full potential is to consume the entire leaf. But that doesn’t mean you need to start eating tea leaves. The simplest solution is to just enjoy a bowl of matcha. Because matcha is straight, stoneground tea leaves, matcha provides you with green teas powerful arsenal of vitamins, minerals, antioxidants, and amino acids in a way no other green tea can.
Although numerous claims have been made for the health benefits of green tea, human clinical research has not provided conclusive evidence of any effects. In 2011, a panel of scientists published a report on the claims for health effects at the request of the European Commission: in general they found that the claims made for green tea were not supported by sufficient scientific evidence. Although green tea may enhance mental alertness due to its caffeine content, there is only weak, inconclusive evidence that regular consumption of green tea affects the risk of cancer or cardiovascular diseases, and there is no evidence that it benefits weight loss.
Scientists at Tufts University compared the “ORAC” (Oxygen Radical Absorbance Capacity, a measurement of the total antioxidant power of foods and other chemical substances) of black and green tea and 22 fruits and vegetables, and found green tea brewed for five minutes outranked even so-called superfoods on the produce list. And EGCC, a catechin found in tea (and shows highest levels in green tea) has been shown to protect the DNA in cells from cancer-inducing changes. Antioxidants are essential for neutralizing and removing free radicals found in the bloodstream that can damage cells and cause disease. This antioxidant ability may be why one benefit of green tea is it’s believed to play a role in cancer prevention. Next, find out more health benefits of drinking any type of tea.
Like black and green tea, rooibos is rich in polyphenols, such as rutin and quercetin. Cell and animal studies, mostly from South Africa, have shown that rooibos extracts have antioxidant, immune-stimulating, and anti-cancer properties. But studies of rooibos tea in people are limited. There’s little or no evidence to back claims that it relieves constipation, headaches, eczema, asthma, insomnia, high blood pressure, mild depression, ulcers, diabetes, and so on.
