妈妈饮食习惯可能改变宝宝代谢基因

Core Insights - The study reveals that the scents of high-fat foods, such as bacon, experienced by mothers during pregnancy and lactation can influence the metabolic health of their offspring, potentially increasing obesity risk [1][2] - The research emphasizes that maternal diet impacts not only the nutritional intake but also the "odor language" that communicates with the fetus through amniotic fluid and breast milk [1] Group 1: Research Findings - The experiment involved pregnant and lactating mice being given two types of diets: one with bacon scent and one standard diet, showing no weight difference in mothers or fetuses but distinct metabolic outcomes in offspring [1] - Offspring exposed to bacon scent during early life showed increased body fat accumulation, insulin resistance, and lower energy expenditure compared to the control group, indicating a predisposition to obesity and metabolic disorders [2] Group 2: Implications - The study suggests that early sensory experiences, such as food scents, create a "metabolic memory" in the brain, affecting future responses to food and energy usage [2] - While the research is based on mice, it highlights the potential importance of maternal dietary scents in shaping the health trajectory of future generations, suggesting a new avenue for obesity and metabolic disease prevention [2]
