The five best foods for diabetics are lean proteins, low-glycemic carbohydrates, healthy fats, fiber-rich foods, and non-starchy vegetables. Lean proteins, such as chicken, turkey, fish, and eggs, are important for keeping blood sugar levels stable. Low-glycemic carbohydrates, such as legumes, whole grains, and certain fruits, are digested slowly and help to prevent spikes in blood sugar levels. Healthy fats, like olive oil, avocado, and nuts, provide essential nutrients and help to slow the absorption of carbohydrates. Fiber-rich foods, like beans, oats, and berries, help to maintain healthy blood sugar levels and also promote digestive health. Non-starchy vegetables, such as leafy greens, broccoli, and cauliflower, are low in calories and provide essential vitamins and minerals. Together, these five food groups can help diabetics to achieve balanced nutrition and better manage their blood sugar levels.
