To ensure trial data accuracy and avoid potentially skewed results, participants also adhered to a diet that was low in polyphenols, which are
that are typically found in fruits, vegetables, spices, and teas. This helped researchers determine if the polyphenols found in green tea really did have an effect on participants.After measuring pro-inflammatory proteins in stool samples of the participants, researchers came to the conclusion that consuming green tea extract can help lower blood sugar levels and lessen gut inflammation.
"Based on what we know about the causal factors behind metabolic syndrome, there is potential for green tea to be acting at least in part at the gut level to alleviate the risk for either developing it or reversing it if you already have metabolic syndrome," he said.
