Want to cut that extra flab? Drinking green tea can help reduce obesity as well as inflammation in the gut, finds a study.

The findings, published in the Journal of Nutritional Biochemistry, showed that mice fed a high-fat diet supplemented with green tea gained about 20 per cent less weight and had lower insulin resistance than mice fed an otherwise identical diet without tea.

Mice fed a diet of two per cent green tea extract had an improved gut health including more beneficial microbes in the intestines and less permeability in the intestinal wall — a condition called “leaky gut” — than those that ate a diet without it.

Leaky gut is a problem in humans that contributes to widespread low-grade inflammation.

“This study provides evidence that green tea encourages the growth of good gut bacteria, and that leads to a series of benefits that significantly lower the risk of obesity,” said lead author Richard Bruno, Professor at the Ohio State University.

For eight weeks, the team fed half of the male mice a high-fat diet that causes obesity and half were fed a regular diet. In each of those groups, half ate green tea extract mixed with their food.

Female mice were not included as they are resistant to diet-induced obesity and insulin resistance.

Green tea also protected against the movement of endotoxin — the toxic bacterial component — out of their guts and into the bloodstream.

“Consuming a little throughout the course of a day with food might be better,” Bruno said.

Research suggests that regular tea drinkers have better organised brain regions and this is associated with healthy cognitive function as compared to non-tea drinkers.

“Our results offer the first evidence of positive contribution of tea drinking to brain structure, and suggest that drinking tea regularly has a protective effect against age-related decline in brain organisation,” according to a study authored by Feng Lei, Assistant Professor from the National University of Singapore.

Previous researchers have demonstrated that tea intake is beneficial to human health and the positive effects include mood improvement and cardiovascular disease prevention.

For the study published in the journal Aging, the research team recruited 36 adults aged 60 and above and gathered data about their health, lifestyle and psychological well-being.

The elderly participants also had to undergo neuropsychological tests and magnetic resonance imaging (MRI).

The study was carried out from 2015 to 2018.

Upon analysing the participants’ cognitive performance and imaging results, the research team found that individuals who consumed either green tea, oolong tea, or black tea at least four times a week for about 25 years had brain regions that were interconnected in a more efficient way.

“We have shown in our previous studies that tea drinkers had better cognitive function as compared to non-tea drinkers,” Lei said.

“Our current results relating to brain network indirectly support our previous findings by showing that the positive effects of regular tea drinking are the result of improved brain organisation brought about by preventing disruption to interregional connections,” he added. (IANS)
