Blood Sugar

Sugary foods, such as white bread, fruit juice, soda and ice cream, cause a spike in blood sugar. While your body can handle occasional influxes of glucose, over time this can lead to insulin resistance, which can go on to become type 2 diabetes. Complex carbohydrates, such as whole grain bread, oatmeal and brown rice, cause a slow release of sugar into the bloodstream, which helps regulate blood sugar.
