Green Tea: How does it help, and for whom is it beneficial?
Green tea is composed of a high concentration of polyphenols, a majority of which include flavanols. Flavanols are widely called catechins, the most active catechin being the epigallocatechin-3-gallate (EGCG). Within the world of nutrition, green tea is time and again touted as a nutritional supplement with a surfeit of health benefits. These benefits are sweeping and particular roles of green tea have been acknowledged to perk up the signs or reverse the disease damage amongst individuals with cancer, autoimmune disorder, heart problems, smoking impediments, liver disorders, chronic inflammation, and much more. Over and over again, the roles of green tea often extend beyond and while green tea intake is significant for those with various health conditions, green tea when taken by healthy people may be integral in the deterrence of a majority of following disorders.
Together with helping to regulate the chronic inflammatory processes linked to the most autoimmune disorders, EGCG has been revealed to restrain the multiplication of the auto-reactive T cells. These cells work against the body, giving rise to several forms of autoimmune conditions. In addition, EGCG may help to control the balance of T-helper cells, which may cut the pathogenesis of arthritic disorders, particularly rheumatoid arthritis.
Heart Disease & Stroke Risk
It is also seen that people who took green tea supplements on a daily basis had a 14% lower risk of heart problems and stroke. The research on green tea and stroke risk comes on the wake of manifold studies presenting relationships between green tea and cardiovascular health. Manifold studies observed the intake of green tea has been related to a lower risk of death from heart attacks by 26% as well as a lower risk of coronary artery disease by 28%.
The aforesaid anti-carcinogenic effects of Green tea may play a key role in checking the incidence of liver disorders. Active polyphenols detoxify the reactive oxygen species, avoiding the destruction of the liver cells from oxygen free radicals and resulting in an oxidative DNA damage. A number of studies have shown that, most probably through this method, green tea intake can ease liver disorders or liver cancer.
Chronic Inflammatory Disease
EGCG may be most imperative flavanol when it comes to inflammation regulation. EGCG has been known to considerably curb the production of cytokines, pro-inflammatory mediators. Suppressing cytokines reduces the chronic inflammation and has been seen to recover the inflammation-linked signs in arthritis models.
Type 2 Diabetes Risk
Type 2 Diabetes is sweeping all over the world, and food manufacture practices, affordability, as well as availability are making it more difficult for individuals to access healthy alternatives. The simplicity of accessing and affording noxious foods is enhancing the risk of diabetes among populations. Green tea, in addition to coffee, has been associated with lowering the risk of type 2 diabetes, though the mechanism is unidentified and the data contradictory. On the other hand, in a study of 40,000 plus individuals followed for 10 years, researchers observed that everyday intake of green tea supplements may lower the risk of type 2 diabetes.
The Polyphenols in green tea have been known to counteract carcinogens, whilst the antioxidant effects may undo the endothelial dysfunction in healthy smokers. The setback of endothelial dysfunction in smokers is significant as it plays a key role in the pathogenesis of atherosclerosis as well as cardiovascular disorder.
Cancer & Tumour Growth
Cancer is a principal cause of death these days, after heart disorders. Green tea has by now revealed to be favourable in averting the principal cause of deaths; now research studies have demonstrated that the EGCG may have an effect on distorted cells by restraining the growth of particular cell lines, inducing apoptosis, as well as modifying the gene expression to avoid distorted cells from becoming cancerous.
Weight Loss & Weight Maintenance
The effects of green tea on weight loss may be attributable to two constituents: caffeine as well as EGCG. Caffeine alone does play considerable role in augmenting the energy expenditure, but when taken along with EGCG, the combination promotes the energy expenditure and fat oxidation to a higher degree. This may activate weight loss, and further data reveals that frequent green tea intake can further assist to maintain weight.
In shaping whether or not green tea is for you, the answer is possibly a yes. While there are risks by way of over intake, one capsule a day has been shown to be helpful for the all-around healthy individuals in preventing disease and for the people experiencing various diseases or ailments.
