Diabetes relates to a persistent elevation in blood glucose levels. Many factors influence the development and management of diabetes including genetics, weight, predisposing medical conditions and diet. A healthy diet that is rich in lean protein, healthy grains, fruits and vegetables have a beneficial impact on stabilizing blood sugar levels. Foods that are high in starch, sugar and saturated fat can cause spikes in blood glucose levels and contribute to weight gain. Excess weight is a risk factor in the development of diabetes and people trying to manage their blood sugar levels should take steps to manage their weight.
