Can a cup of green tea fix your gut and fight inflammation?

This study tested whether taking a green tea extract supplement for one month could improve gut health and reduce harmful inflammation in people with metabolic syndrome, a cluster of conditions like high blood pressure and high blood sugar. Forty-six participants, including some healthy adults for comparison, took either the green tea extract or a placebo for a month, then switched to the other treatment for another month. Researchers measured many blood and stool markers to see if the extract helped seal a 'leaky gut' and lower body-wide inflammation.
