Catechins, especially EGCG, have strong antioxidant activity and are notable for their ability to scavenge free radicals. Overall, the strongest evidence for the beneficial effects of tea catechins comes from laboratory and animal studies, with epidemiologic studies and randomized controlled trials being less conclusive.

In humans, many factors can interfere—genetic factors, dietary factors, other lifestyle factors. Human intervention studies, however, are a different story.

How Catechins Work The proposed mechanisms of green tea catechins include far more than antioxidant activity. For example, catechins can bind to specific regulatory proteins and enzymes, modulating specific signaling and metabolic pathways.

Both of these mechanisms can help prevent metabolic syndrome, type 2 diabetes, CVD, and cancer. This makes it difficult to attain a therapeutic dose, even when administered intravenously, and getting them to reach target tissues remains a challenge.

Intestinal microbes can degrade catechins, yet the resulting metabolites may have biological activity—an area that needs more research.

Although catechins have antioxidant properties, they also can become pro-oxidant, generating reactive oxygen species ROS , which include free radicals, although this may be more likely in an isolated cell culture than in living humans.

In other words, it appears that the proposed benefits of catechins may come from their ability to both generate and scavenge ROS. Recent systematic reviews and meta-analyses have found that green tea consumption was associated with reduced risk of breast and ovarian cancers,11,12 and both in vitro and in vivo studies have established chemoprotective effects, although with some inconsistencies between studies.

Kumar says some of the clinical trials evaluating green tea catechins for prostate cancer prevention are promising, but more research is needed. Cardiometabolic Disease So what avenues of research likely hold the most promise?

Indeed, large cohort studies in Japan have found an association between increased green tea consumption and decreased risk of CVD-related death, although consumption may have to meet or exceed seven cups per day.

Catechins may inhibit specific enzymes and modulate signaling pathways, helping to prevent type 2 diabetes and metabolic syndrome. This may be simply due to variation in study lengths and participant characteristics, but clearly more well-controlled, long-term studies are needed. Cognitive Health Oxidative stress and generation of free radicals play a role in neurodegenerative diseases, just as they do in cancer and CVD.

Both clinical and epidemiologic studies have shown that green tea consumption may have a protective effect against neurodegenerative diseases and cognitive impairment, but, again, at consumption levels far above average.

However, randomized controlled trials have been inconclusive. However, at this time there are few animal or human studies to support these theories. Viral Illnesses In in vitro studies, catechins minimize the propensity of the influenza virus to infect and proliferate, in part by inhibiting its ability to interact with the cell membrane when it invades a cell.

Epidemiologic studies and randomized controlled trials have found a significantly lower incidence of influenza in individuals with higher consumption of green tea or, in the case of the clinical trials, green tea capsules. How to Counsel Clients Researchers have observed beneficial effects on weight, metabolic syndrome, and type 2 diabetes with intake of three to four 8-oz cups of green tea per day, which supplies about to mg of catechins, but lower levels of intake would still add to the total intake of polyphenols in the diet.

He says that when catechin intake stops, people generally recover. Yang has been researching green tea for 30 years, and he says the research has become more mature, perhaps tempering the highs of early optimism. Green tea happens to have some beneficial health effects. References 1.

Moreover, researchers discovered that longer brewing time yielded higher concentrations of catechin, TPC, and antioxidant activity values—though the majority of phenolics were already extracted within two minutes of brewing—so again, aim for this brewing time at minimum.

Common Tea Formulations Modulate In Vitro Digestive Recovery of Green Tea Catechins. Rodney J. Green, Angus S. Murphy, Burkhard Schulz, Bruce A.

Watkins and Mario G. Epidemiological evidence suggests a role for tea catechins in reduction of chronic disease risk. However, stability of catechins under digestive conditions is poorly understood.

The objective of this study was to characterize the effect of common food additives on digestive recovery of tea catechins. Green tea water extracts were formulated in beverages providing 4.

Common commercial beverage additives; citric acid CA , BHT, EDTA, ascorbic acid AA , milk bovine, soy, and rice , and citrus juice orange, grapefruit, lemon, and lime were formulated into finished tea beverages at incremental dosages.

There are also related studies by Sergio Pérez-Burillo, et al [ 3 ] and Eun Sung Jung, et al [ 4 ] that study the effects of green tea supplementation on the human gut microbiome.

These studies showed that green tea stimulated the growth of beneficial bacteria and hindered the growth of detrimental ones. Besides improving gut health and blood glucose levels, green tea has plenty of other health benefits.

It is rich in antioxidants, which combat oxidative stress in our bodies. Oxidative stress occurs due to an excess level of free radicals, which damage cells and play a key role in age-related degenerative conditions such as cancer.

Green tea also benefits our cardiovascular health — it can lower blood pressure and cholesterol levels while reducing the risk of developing detrimental cardiovascular conditions. Some research has even shown that consuming 5 cups of green tea in a day lowers the mortality risk from a cardiovascular condition [ 5 ].

Moreover, green tea extract has been studied for its potential role in weight management and metabolic health. Research suggests that the catechins in green tea may enhance fat oxidation and thermogenesis, thereby aiding in weight loss and maintenance.

Additionally, green tea extract may help regulate lipid metabolism, leading to improvements in cholesterol levels. The caffeine in green tea stimulates the brain, allowing you to feel more alert and focused.
