The glycemic index (GI) refers to impact of the ingestion of carbohydrate-containing foods on blood sugar concentrations. High-GI foods increase blood glucose levels more and for a longer time, than those with low GIs. It appears that those who adopt a low-GI diet have a reduced risk of heart disease, type 2 diabetes mellitus, and obesity. Carbohydrate-containing foods on a low-GI diet include ...

Evidence suggests that neurobiological preferences to consume highly hedonic foods translate (via implicit processes) into poor eating choices, unless overturned by inhibitory mechanisms or interrupted by explicit processes. The primary aim of the current study was t...
