Key Points
- Skipping or not optimizing breakfast can impact blood sugar levels.
- A breakfast rich in fiber, protein and healthy fats can help stabilize blood sugar.
- Balanced breakfasts, like overnight oats, provide blood-sugar-stabilizing nutrients.
If you are one of the 40 million people in the US living with diabetes or one of the 115.2 million people with prediabetes, you probably know that what you eat directly impacts your blood sugar levels. One meal that’s often skipped or overlooked is breakfast—yet it’s essential for stable blood sugar. If you find yourself scratching your head over what to eat, don’t fret. Breakfast foods don’t need to be complicated. “A healthy and balanced breakfast can be delicious, practical and easy to prepare,” says Vandana Sheth, RDN, CDCES, FAND. From whole-wheat toast with nut butter and berries to overnight oats, these stress-free options provide the nutrients you need to keep your blood sugar in check.
How Breakfast Helps Blood Sugar
Regularly eating breakfast can “reduce sharp rises and falls in blood sugars, improve insulin sensitivity, prevent excess hunger and overeating later on, and stabilize energy and metabolism, which maintains blood sugar balance,” says Maria Fraga, RD, CDCES.. When choosing a diabetes-appropriate breakfast, dietitians recommend high-fiber options. The American Diabetes Association recommends a goal of 14 grams of fiber per 1,000 calories consumed. So, if you eat a 2,000-calorie diet, you should eat at least 28 grams of fiber daily.
While there is no universal prescription for fiber needs at breakfast, “Aim to consume roughly 8 to 10 grams of fiber at breakfast to help you feel full and maintain steady blood sugar levels,” recommends Fraga.
Other nutrients that help promote healthy blood sugar levels include protein and heart-healthy fats because, along with fiber, they help slow digestion and prevent high blood sugar spikes. Each breakfast choice below provides a mix of fiber, protein and healthy fats, while remaining low in added sugar and saturated fat.
1. Tofu Scramble with Avocado & Greens
In addition to supporting blood sugar control, protein helps you feel fuller for longer. When it comes to high-protein breakfast foods, eggs are often top of mind. And while they’re certainly a nutritious option, plant-based proteins, like tofu, deserve just as much attention. Research has shown that plant-forward eating patterns are associated with a lower risk of developing type 2 diabetes and can improve body weight and blood sugar control in those already living with the condition. Plus, if you love scrambled eggs, you’ll probably enjoy a well-seasoned tofu scramble—it offers similar texture and versatility with the added benefits of plant-based protein.
Tofu scramble pairs well with avocados and dark leafy greens, which are rich in blood-sugar-stabilizing nutrients. Avocados are rich in heart-healthy fat and fiber. In fact, one avocado contains almost 14 grams of fiber. Dark leafy greens like spinach, kale or collards also contain fiber, plus they are high in vitamins and minerals.
2. Whole-Grain Toast with Almond Butter, Berries & Chia Seeds
Looking for something with natural sweetness? Consider a whole-grain, high-fiber bread with a smear of nut butter and antioxidant-packed berries. While any nut butter and fruit works well with toast, Sheth recommends it with almond butter, berries and chia seeds. When choosing a bread, dietitians recommend one with at least 3 grams of fiber per slice. As mentioned above, “Fiber slows down the conversion and absorption of glucose and helps with gut health,” notes Sheth.
Your toast isn’t the only source of fiber here—berries and chia seeds add even more, with 1 cup of blueberries providing 4 grams and 1 tablespoon of chia seeds delivering nearly 5 grams.
3. Greek Yogurt Parfait with Cinnamon
Strained (Greek-style) yogurt is another protein-rich option for a filling breakfast. “Protein supports a feeling of satiety and helps prevent blood sugar spikes,” says Sheth. In addition to protein, strained (Greek-style) yogurt contains probiotics, calcium and vitamin D (fortified). When managing diabetes, it’s generally best to choose a plain nonfat or low-fat option. Higher intakes of saturated fat can increase the risk of heart disease, a condition that’s more likely to develop in people with diabetes.
Add a serving of fibrous fruit, chopped nuts and seeds, or a dollop of nut butter to make it extra filling and flavorful. Sheth loves pairing strained (Greek-style) or Icelandic skyr yogurt with diced pear, chopped nuts and cinnamon. You can use fresh or frozen fruit for your convenience. Cinnamon has been studied for its therapeutic effects, from helping lower blood sugar and cholesterol to reducing inflammation. One small study found that taking about 4 grams (roughly 1 teaspoon) of cinnamon daily for four weeks helped lower blood sugar levels in people with prediabetes (the precursor to diabetes). However, more research is needed to confirm these benefits. If you take medicine to manage your blood sugar, talk to your health care provider before using cinnamon daily since it can interact with your medication.
4. Overnight Oats
Overnight oats are a winner when it comes to an easy grab-and-go breakfast. Plus, you can simplify your routine and make several servings for the week. “My go-to is overnight oats for steady energy and balanced blood sugar,” says Lila Cornelio, M.P.H., RDN. Oats are a source of complex carbohydrates and contain a soluble fiber called beta-glucan. Beta-glucan has various health benefits, including helping lower insulin resistance, reducing blood sugar and cholesterol and supporting your gut. Increased intake of whole grains, like oats, is also linked to reduced risk of developing diabetes.
Get creative with overnight oats. You can use ingredients like fresh fruit, including cherries, apples, blackberries and blueberries, and seeds, like pumpkin, flax, hemp or chia and plant-based milks. Fraga recommends steel-cut oats with flaxseed, chopped peaches or strawberries, and cinnamon.
5. Veggie Bowl
For a savory twist, make a veggie bowl with your favorite foods. Vegetables are rich in fiber, vitamins, minerals and antioxidants. They’re also low in calories, which can support weight management—an important factor in improving your blood sugar levels.
When making a veggie bowl, you can easily incorporate the plate method—a tool to create balanced meals. The plate method encourages you to fill half of your plate with non-starchy vegetables such as kale, onions, peppers, mushrooms, leeks, scallions and tomatoes. Then, make one-quarter of your plate lean protein (think eggs or low-fat cottage cheese) and the other quarter fiber-rich carbohydrates, such as whole grains or starchy vegetables. Drizzling olive oil on top adds extra flavor and healthy fats.
Our Expert Take
If you’re looking for breakfast choices that support blood sugar levels, focus on fiber, protein and healthy fats. Foods like fruit, vegetables, whole grains, nuts, seeds, strained (Greek-style) yogurt and avocado can help you create a breakfast that’s both sustainable and nutritious. Keep in mind that there’s no one-size-fits-all approach to managing diabetes, so it’s always best to work with your primary care provider for personalized guidance.
