Managing blood sugar starts with choosing foods that digest slowly, provide steady energy, and don’t spike glucose levels. The right choices help your body use insulin more effectively and can even reverse prediabetes over time.
This list covers 97 options across vegetables, proteins, grains, fruits, and healthy fats. You’ll find everything from leafy greens to lean meats to whole grains that fit naturally into your meals. All values are approximate. Unless stated otherwise, nutritional values are based on a cooked 1-cup (240ml) serving.

FAQs
The best breakfast for prediabetes combines protein, healthy fats, and fiber while limiting refined carbs. Good options include eggs with vegetables and whole grain toast, Greek yogurt with nuts and berries, or oatmeal topped with almond butter and chia seeds. These combinations help keep blood sugar stable throughout the morning.
Yes, fruit can be part of a prediabetes diet when eaten in moderation and paired with protein or healthy fats. Berries, apples, and pears are particularly good choices because they're high in fiber and lower on the glycemic index. Limit fruit juice and dried fruit, which can spike blood sugar more quickly.
Potatoes aren't necessarily bad, but they should be eaten in smaller portions and prepared in healthy ways. Sweet potatoes are a better choice than white potatoes due to their higher fiber content and lower glycemic impact. Pair any potato with protein and non-starchy vegetables, and avoid frying them.
The best snacks combine protein with fiber to prevent blood sugar spikes. Try options like apple slices with almond butter, raw vegetables with hummus, a handful of nuts, cheese with whole grain crackers, or hard-boiled eggs. Aim for snacks under 200 calories that keep you satisfied between meals.
Rice can be included in a prediabetes diet, but portion control matters and some types are better than others. Brown rice, wild rice, and cauliflower rice are better options than white rice because they have more fiber and nutrients. Stick to a half-cup serving and fill the rest of the plate with vegetables and lean protein.
Most people with prediabetes should aim for 20-30 grams of protein per meal to help stabilize blood sugar and maintain muscle mass. Good sources include fish, chicken, turkey, eggs, Greek yogurt, legumes, and tofu. Spreading protein throughout the day helps manage hunger and prevents blood sugar fluctuations.
Pasta can be enjoyed occasionally with some modifications to reduce its impact on blood sugar. Choose whole grain or legume-based pasta, limit portions to one cup cooked, and load up the dish with vegetables and lean protein. Al dente pasta has a slightly lower glycemic index than softer-cooked pasta.
Non-starchy vegetables are excellent for prediabetes and can be eaten liberally without worrying about blood sugar spikes. Leafy greens, broccoli, cauliflower, peppers, tomatoes, zucchini, and Brussels sprouts are all great choices packed with fiber and nutrients. Aim to fill half the plate with these vegetables at each meal.
