医生劝你少吃辣？新研究说：常吃辣的人老得慢

Group 1 - The core finding of the study indicates that consuming spicy food may be associated with a slower biological aging process, particularly in metabolic and renal systems [2][9][11] - The research involved 7,874 participants with an average age of 51.7 years, predominantly Han ethnicity and male [4][18] - Participants were categorized based on their frequency of spicy food consumption, revealing that those who consumed spicy food 3-5 times a week showed a biological age reduction of 0.76 years in metabolic systems and 1.89 years in renal systems compared to non-consumers [2][16][19] Group 2 - The study suggests that consuming spicy food 3-5 times a week is optimal for anti-aging benefits, as higher frequencies do not yield significantly greater effects [13][15][30] - The analysis showed that women benefited more from spicy food consumption, with a biological age reduction of 1.14 years for those eating spicy food 3-5 times a week, nearly double that of men [19][20] - The study also found that Han participants experienced a more significant reduction in biological age compared to non-Han participants, with reductions of 0.79 years versus 0.39 years, respectively [20][21] Group 3 - The potential anti-aging effects of spicy food are attributed to capsaicin, the active component in chili peppers, which may improve vascular function and metabolic processes [21][25] - The study highlights that excessive consumption of spicy food may not provide additional benefits, possibly due to saturation of active components [28][30] - Recommendations suggest that to maximize benefits, individuals should consume fresh chili peppers rather than processed spicy condiments, which may contain unhealthy levels of salt and oil [32][34]
