PNAS的研究将肥胖症与加工食品摄入比与缺乏锻炼更紧密地联系起来。 Study in PNAS links obesity more to processed food intake than lack of exercise.

最近对全国住户抽样调查的一项研究对缺乏锻炼是肥胖的主要原因这一观念提出了质疑,相反却指出了饮食问题,特别是超处理食品的消费问题。 A recent study in PNAS challenges the notion that lack of exercise is the main cause of obesity, instead pointing to diet, particularly the consumption of ultraprocessed foods. 研究人员分析了来自34个国家4 000多人的数据,发现能源支出没有因经济发展而大幅减少。 Researchers analyzed data from over 4,000 people across 34 countries and found that energy expenditure did not significantly decrease with economic development. 研究表明,高卡路里摄入量,特别是加工食品摄入量,与肥胖比减少体力活动更密切相关。 The study suggests that higher calorie intake, especially from processed foods, is more closely linked to obesity than reduced physical activity.
