“吃各种各样的食物”，或饮食多样性，是一个被广泛接受的建议，以促进健康，营养充足的饮食和减少主要慢性疾病的风险。然而，最近来自观察性研究的证据表明，更大的饮食多样性与次优饮食模式有关，即加工食品，精制谷物和含糖饮料的摄入量较高，而最低加工食品（如鱼，水果和蔬菜）的摄入量较低，并且可能与成年人的体重增加和肥胖有关。这份美国心脏协会科学咨询总结了饮食多样性的定义，并回顾了其与肥胖结果，饮食行为和基于食物的饮食质量指标之间关系的现有证据。目前的数据不支持更大的饮食多样性作为促进健康饮食模式和健康体重的有效策略。鉴于目前关于饮食多样性的科学状况，以及没有足够的数据为可能有益于或有害于健康体重的饮食多样性的具体方面提供建议，促进健康的饮食模式是适当的，这种饮食模式强调摄入足够的植物性食物，蛋白质来源，低脂乳制品，植物油和坚果，并限制甜食，含糖饮料，和红肉。
“Eat a variety of foods,” or dietary diversity, is a widely accepted recommendation to promote a healthy, nutritionally adequate diet and to reduce the risk of major chronic diseases. However, recent evidence from observational studies suggests that greater dietary diversity is associated with suboptimal eating patterns, that is, higher intakes of processed foods, refined grains, and sugar-sweetened beverages and lower intakes of minimally processed foods, such as fish, fruits, and vegetables, and may be associated with weight gain and obesity in adult populations. This American Heart Association science advisory summarizes definitions for dietary diversity and reviews current evidence on its relationship with obesity outcomes, eating behavior, and food-based diet quality measures. Current data do not support greater dietary diversity as an effective strategy to promote healthy eating patterns and healthy body weight. Given the current state of the science on dietary diversity and the insufficient data to inform recommendations on specific aspects of dietary diversity that may be beneficial or detrimental to healthy weight, it is appropriate to promote a healthy eating pattern that emphasizes adequate intake of plant foods, protein sources, low-fat dairy products, vegetable oils, and nuts and limits consumption of sweets, sugar-sweetened beverages, and red meats.
