Randomized Controlled Trial
Price and maternal obesity influence purchasing of low- and high-energy-dense foods.
Price can influence food purchases, which can influence consumption. Limited laboratory research has assessed the effect of price changes on food purchases, and no research on individual differences that may interact with price to influence purchases exists. ⋯ These results show the relevance of considering price change as a way to influence food purchases of LED compared with HED foods and the possibility that individual differences may influence the own-price elasticity of HED foods and substitution of LED for HED foods.

Findings of the effect of dietary glycemic index (GI) and glycemic load (GL) on the risk of incident diabetes are inconsistent. ⋯ The proposed protective effect of low-dietary GI and GL diets on diabetes risk could not be confirmed in this study.
