Additionally, mice fed the green tea supplement showed a nearly 30 percent increase in lipid excretion, suggesting that the EGCG was limiting fat absorption by inhibiting pancreatic lipase.To design this research work, scientists handed out questionnaires to nearly 14,000 respondents aged 65 or older. The participants answered questions about general diet, green tea consumption and lifestyle.
