Study results show there are epigenetic changes in women consuming tea, but not in men. Interestingly, many of these epigenetic changes were found in genes involved in cancer and estrogen metabolism. Previous studies have shown that tea consumption reduces estrogen levels which highlights a potential difference between the biological response to tea in men and women.
The metabolites produced by the bacteria in the stomach chemically communicate with cells, including cells far beyond the colon, to dictate gene expression and health in its host.
The impact of any diet is likely dependent on the genetic composition of the individual eating the diet, meaning that different individuals have different optimal diets.
Almost all of our genes may be influenced by the food we eat.
