The price of foods and beverages is a critical driver of food choice, particularly among families and households with limited food budgets. Policies targeting unhealthy food and beverage price promotions represent an untapped policy target for improving population diets and health. Here we review policy options for reducing the frequency and influence of price promotions on unhealthy foods and beverages (high in one or more of salt, sugar and saturated fat), and demonstrate their potential to complement other food policies and improve population diets.
Price promotions on unhealthy foods and beverages are ubiquitous in many settings globally and appear to be more common than price promotions for healthy food. Shoppers appear to be more responsive to price promotions on unhealthy foods and beverages compared to price promotions for healthier items, with evidence that discounts lead to impulse purchases, stockpiling and overconsumption. A range of policy options exist to reduce the influence of price promotions on unhealthy foods and beverages, but none have been tested in the real world, meaning the industry and consumer responses to such policies are unclear. Policies that reduce the prevalence and influence of unhealthy food and beverage price promotions should be considered as part of a comprehensive approach to improving population diets.
目的综述:食品和饮料的价格是影响食物选择的一个关键因素,尤其是对于那些食品预算有限的家庭和住户而言。针对不健康食品和饮料的价格促销活动进行干预,代表了改善人群饮食和健康的一个潜在政策目标。在这里,我们对降低不健康食品和饮料(高盐、高糖和高饱和脂肪中的一种或多种)的价格促销频率和影响力的政策选择进行了综述,并展示了它们对其他食品政策的补充作用和改善人群饮食的潜力。
最近的发现:在全球许多地方,不健康食品和饮料的价格促销活动无处不在,且似乎比健康食品的价格促销活动更为常见。与针对更健康产品的促销活动相比,消费者对不健康食品和饮料的促销活动似乎更敏感,有证据表明折扣会导致冲动购买、囤货和过度消费。存在一系列政策选择可以降低不健康食品和饮料价格促销活动的影响,但这些政策都没有在现实世界中进行过测试,因此,这些政策对行业和消费者的影响尚不清楚。减少不健康食品和饮料价格促销活动的流行程度和影响力的政策,应被视为改善人群饮食的综合方法的一部分。
