Green tea continues to be a preferred food plan and health pattern, whose proponents take into account it a ‘superfood’ for its marketed well being advantages equivalent to weight reduction, improved coronary heart well being, and antioxidant content material. It seems a big part of individuals consider their weight reduction journey is incomplete with out at the least three cups of inexperienced tea day by day. Typically folks additionally sweeten it with honey, making it unsuitable for weight reduction. There isn’t any doubt that it is a superb supply of catechins like epigallocatechin gallate or EGCG that act as antioxidants and are linked to quite a few well being advantages. However, inexperienced tea alone can not ship the specified end result and extreme consumption can even trigger critical negative effects.
The advantages of ECGC in inexperienced tea have been extensively studied, however the outcomes up to now have failed to provide sufficient sound proof that it really works to detoxify your physique, deal with illnesses and promote longevity. Well being and longevity are decided by a number of components, together with a various food plan that inexperienced tea could possibly be part of.

Proof of inexperienced tea’s advantages
Inexperienced tea comprises antioxidants which are helpful to general well being. There may be, nonetheless, a must critically consider the particular claims of it enabling weight reduction and wholesome ageing, stopping most cancers and bettering mind perform.
Inexperienced tea is closely promoted for its results on burning fats and enhancing metabolism. The proposition relies on the observation that catechins in tea forestall weight problems by rising thermogenesis. However, scientific trials haven’t examined this speculation. Nearly all commercially obtainable ‘fats burners’ comprise inexperienced tea extract as an ingredient. These ‘fats burners’ have harmful side effects as properly.
Inexperienced tea can also be related to a decreased threat of diabetes. One meta-analysis studied 17 randomised managed trials (RCTs) and concluded that inexperienced tea decreased fasting glucose and glycated haemoglobin — two biomarkers of sort 2 diabetes. Comparable outcomes have been noticed in a retrospective cohort study from Japan involving 17,413 members. Nevertheless, the constraints embody self-reported diabetes and lack of consideration for different dietary components.
Researchers have discovered an affiliation between ECGC and a decrease threat of cancers equivalent to breast most cancers, prostate most cancers, lung most cancers. Most evidence, nonetheless, is epidemiological, observational, or based mostly on a mouse mannequin. There isn’t any RCT with important proof to determine the impact of ECGC in stopping cancers. Likewise, there are multiple mechanistic knowledge suggesting that inexperienced tea polyphenols like ECGC, theaflavins and catechins would possibly forestall the neurodegenerative results of illnesses equivalent to Alzheimer’s or Parkinson’s. Nevertheless, scientific research on people are nonetheless not obtainable to help this declare.
The proof doesn’t help inexperienced tea as a “superfood” to remedy all illnesses. All kinds of different meals can be found with glorious antioxidant profiles and vitamins that will present comparable well being advantages.

Don’t drink an excessive amount of
An excessive amount of of all the pieces is dangerous. In a 2007 research, researcher M Nathaniel Mead mentioned that animal-based analysis on inexperienced tea polyphenols was discovered to trigger liver, kidney, and gastrointestinal injury. There are a number of case experiences available on people demonstrating that enormous consumption of inexperienced tea extract would possibly trigger liver damage. Individuals with liver dysfunction should seek the advice of their doctor earlier than beginning to eat any drugs that comprise the extract. Tannin, current in teas, together with inexperienced tea, is linked to poor iron absorption and the onset of anaemia. In a case report, a 48-year-old man, who consumed six cups of inexperienced tea each weekday for seven years, was discovered to have developed anaemia. An excessive amount of caffeine can even lead to anxiousness, sleep disturbance, and an upset abdomen.
How a lot is an excessive amount of? It’s a million-dollar query for the reason that pointers aren’t very clear about inexperienced tea consumption. To start with, not everybody ought to drink inexperienced tea. A radical medical historical past must be taken earlier than consumption. It’s also unclear if inexperienced tea is secure past a sure consumption. America Nationwide Centre for Complementary and Integrative Well being recommends eight cups of inexperienced tea per day. Nevertheless, it’s best to verify the label to find out how a lot caffeine is within the product. To keep away from hostile results, I like to recommend ingesting not more than two to 3 cups a day.

Different antioxidant meals and drinks
For my part, no single meals or drink can present essentially the most beneficial well being end result. Total, well being advantages are decided by the composition of a food plan. Regardless of this, if you’re too dedicated to having inexperienced tea on daily basis, know that there are quite a few different alternate options which are low cost, handy, and stuffed with vitamins. A few of these choices are espresso, pomegranate, strawberries, blueberries, blackberries, amla, and citrus fruits. Even supposing espresso has more antioxidants than inexperienced tea, increased caffeine consumption must be prevented to forestall sleep disturbances. Espresso has additionally been linked to well being advantages equivalent to weight reduction, decreased threat of colorectal and liver most cancers, and preventive results on neurodegenerative illnesses. Drinks are naturally most popular over meals to make sure day by day antioxidant consumption as ingesting a number of cups of espresso is less complicated than consuming a bowl of berries.
A plate stuffed with recent inexperienced greens and antioxidant-rich fruits is nutritionally superior to a cup of tea or espresso. Complete vegatables and fruits are excessive in pure polyphenols in addition to fibre and micronutrients. With nuts and seeds added to this salad bowl, the dietary profile may be enhanced additional.
