Word of Caution: Despite all of these health benefits of rooibos tea, there can be a downside for some people. Since rooibos is so powerful, it can interfere with treatments for various conditions, including chemotherapy for cancer patients. Also, rooibos has shown estrogenic activities in certain studies, so it might not be a good idea to use if you have hormone-sensitive cancer like breast cancer.
Green Tea comes from Camellia sinensis leaves that are immediately steamed or pan-fired rather than being exposed to air so that no oxidation occurs. This special handling makes for a more delicate brew that is typically lower in caffeine than black and Oolong teas. Although amounts vary, green teas are highest in polyphenols known as EGCG, which is why so many make it part of their healthy lifestyle.
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.
Today, an estimated 2.5 million tons of tea leaves are produced each year throughout the world, with 20 percent of that being green tea. Green tea didn’t become popular or widely distributed outside of Asia until about the early 1900s. China, other countries in Asia, countries in North Africa, the United States and Europe currently consume the most green tea worldwide.
Neither red nor black tea is to be confused with Rooibos, often called “Red Bush Tea” or “Rea Tea” for short. Rooibos (Aspalathus linearis) is a South African plant that is a member of the legume family and is not related to the tea plant (Camellia sinensis). Rooibos has a very different taste and feel than red (or black!) tea, it is much sweeter and lighter than black tea, although it is often mixed with sugar and cream or a lemon as you might find heavy black tea drinking countries such as England or the United States.
In January 2015, we wrote about the rapid rise of matcha on the American beverage landscape and posed the question, “Have we reached maximum matcha saturation?” Three years later, we're living amid matcha croissants, matcha custard pie, matcha face masks, matcha lifestyle guides and $50 cups of matcha itself. Clearly, the answer was "No." But what is this powder we're whisking into green lattes, baking into doughnuts, blending into smoothies, and adding to our fish fillets?
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."
Red rooibos tea is an excellent thirst quencher and does wonders for athletes, hyperactive children, and those who travel often, whether for pleasure or business. Most people prefer to brew red rooibos loose leaf tea in its natural form without using any sweeteners. For those who simply want a refreshing drink, caffeine-free rooibos tea is an ideal choice.
The polyphenols in green tea, especially EGCG, have been shown to have a particularly powerful effect in supporting skin cells and cellular DNA in the presence of UV radiation from sunlight. May different clinical studies have shown EGCG to help skin defend against UVA and UVB rays. And because these polyphenols can accumulate in the skin, regularly drinking green tea or taking a green tea supplement with EGCG can act as all-day supplemental protection.
Yup, those samurai. The samurai were cultured, fearsome warriors who ranked highly in ancient Japanese caste society. Their identity was built on Zen Buddhism, practicing the principles of discipline, ritual, and purification. The tea ceremony developed into an art form and cultural tradition as the samurai added hundreds of detailed steps in the practice. Specific instructions for how to sit and how to prepare Matcha green tea, the proper hand movements and even the proper design for a tea room were recorded in detail.
Another benefit of green tea it’s is lower in caffeine than most other teas, so you may be able to drink the five cups a day that lowered psychological stress in a large group of Japanese people in a recent study done at Sendai’s Tohoku University Graduate School of Medicine. The researchers didn’t identify any particular component of green tea that might have been soothing, but animal studies suggest that one compound, EGCC, had both sedative and hypnotic effects that tamp down the body’s production of stress chemicals.
Some green tea varieties are better for weight loss than others. If you’re all about that green and on a weight-loss mission, you might want to choose Matcha green tea—the richest green tea source of nutrients and antioxidants. Registered dietitian Isabel K Smith explains why: “The whole leaf is ground and consumed as part of the beverage, as opposed to other (most) types of green tea where the leaves are steeped and then the tea is consumed.”
