Health Effects of Grain Foods in Adults
This study will assess the effects of eating whole grain foods versus refined grain foods with different amounts of added sugar. It is hypothesized that a diet including grain products will have beneficial effects on taste hedonics, appetite, food/energy intake, body weight, blood pressure, acute and chronic glycemia and acute and chronic lipemia compared to customary diets controlling for added sugars, saturated fats and sodium.
