澳大利亚的科学家对数百名参试者进行了长达1年的跟踪调查。其中一组人员食用高脂肪低碳水化合物饮食,另一组则主要吃碳水化合物低脂肪食物。参试者每月见1次营养师,以确保他们坚持某种饮食模式。研究人员在研究刚开始、8周后、24周后及1年后分别对参试者的抑郁、焦虑、愤怒及疲劳等情绪变化进行全过程跟踪记录。结果发现,虽然参试者摄入的热量一样,但情绪差 Australian scientists conducted a one-year follow-up survey of hundreds of participants. One group consumed a high-fat, low-carbohydrate diet, while the other group mainly consumed low-fat carbohydrate foods. The participants see nutritionists once a month to ensure that they adhere to a certain diet pattern. At the beginning, 8 weeks, 24 weeks, and 1 year after the study, researchers performed follow-up records of the participants’ depression, anxiety, anger, and fatigue. The results showed that although the participants had the same caloric intake, they had poor emotions.
