Impact of Food Pricing on Improving Dietary Consumption
2017
While food pricing is a promising strategy to improve diet, the prospective impact of food pricing on diet has not been systematically quantified. This analysis quantified the prospective effect of changes in food prices on dietary consumption through a systematic review of interventional or prospective observational studies of price change and diet.
In general, results supported the efficacy of subsidies to increase consumption of healthful foods, and taxation to reduce intake of unhealthful beverages and foods. In pooled analyses, a 10% decrease in price increased consumption of healthful foods by 12% whereas a 10% increase price decreased consumption of unhealthful foods by 6%. By food group, subsidies increased intake of fruits and vegetables by 14% and other healthful foods, by 16%, without significant effects on more healthful beverages. Each 10% price increase reduced sugar-sweetened beverage intake by 7%, fast foods, by 3%, and other unhealthful foods, by 9%.
