In a meta-analysis of 88 studies, we examined the association between soft drink consumption and nutrition and health outcomes. We found clear associations of soft drink intake with increased energy intake and body weight. Soft drink intake also was associated with lower intakes of milk, calcium, and other nutrients and with an increased risk of several medical problems (e.g., diabetes). Study design significantly influenced results: larger effect sizes were observed in studies with stronger methods (longitudinal and experimental vs cross-sectional studies). Several other factors also moderated effect sizes (e.g., gender, age, beverage type). Finally, studies funded by the food industry reported significantly smaller effects than did non-industry-funded studies. Recommendations to reduce population soft drink consumption are strongly supported by the available science.
在一项对88项研究的荟萃分析中,我们研究了软饮料消费与营养和健康结果之间的关联。我们发现软饮料摄入量与能量摄入增加和体重增加之间存在明显关联。软饮料摄入量还与牛奶、钙和其他营养素的摄入量较低以及多种医疗问题(如糖尿病)风险增加有关。研究设计对结果有显著影响:在方法更强的研究(纵向研究和实验研究与横断面研究)中观察到更大的效应量。其他几个因素也调节了效应量(如性别、年龄、饮料类型)。最后,由食品行业资助的研究报告的效应明显小于非行业资助的研究。现有科学有力支持减少人群软饮料消费的建议。
