Diabetics can eat a variety of foods daily, including non-starchy vegetables (like leafy greens, broccoli, and peppers), whole grains (such as quinoa, brown rice, and oats), lean proteins (like chicken, fish, tofu, and legumes), healthy fats (such as avocados, nuts, and olive oil), and low-glycemic fruits (like berries and apples). These foods help maintain stable blood sugar levels and provide essential nutrients for overall health.
