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.
