If you’re trying to help manage blood sugar levels, foods that are high in fiber, protein, healthy fats, and minimally processed carbohydrates can help slow digestion and reduce sharp blood sugar spikes. No single food can “cure” high blood sugar, but these choices can support better glucose control.
10+ Foods That May Help Support Healthy Blood Sugar
- Leafy green vegetables
- Examples: spinach, kale, lettuce, collard greens
- Low in carbohydrates and rich in fiber and nutrients.
- Beans and lentils
- Examples: chickpeas, black beans, kidney beans, lentils
- High in fiber and plant protein, which can help slow glucose absorption.
- Oats
- Especially steel-cut or old-fashioned oats
- Contain soluble fiber (beta-glucan), which may help improve blood sugar response.
- Nuts
- Examples: almonds, walnuts, pistachios
- Provide healthy fats, fiber, and protein that can help with fullness and steadier glucose levels.
- Fatty fish
- Examples: salmon, sardines, mackerel
- Rich in omega-3 fats that support heart health, which is especially important for people with diabetes.
- Eggs
- A protein-rich food with very few carbohydrates.
- Greek yogurt (unsweetened)
- Provides protein and can be a lower-sugar option compared with sweetened yogurts.
- Berries
- Examples: strawberries, blueberries, raspberries
- Generally lower in sugar than many other fruits and high in fiber.
- Avocado
- High in healthy fats and fiber, which can help slow the rise of blood sugar after meals.
- Chia seeds and flaxseeds
- Rich in fiber and healthy fats; can be added to yogurt, oats, or smoothies.
- Whole grains (in appropriate portions)
- Examples: quinoa, barley, whole-grain breads
- Often cause a slower blood sugar rise than refined grains.
- Cinnamon (as a flavoring)
- Some studies suggest it may have a small effect on blood sugar control, but it should not replace prescribed treatment.
Helpful eating habits
- Pair carbohydrates with protein or healthy fats (for example, fruit with nuts or yogurt).
- Choose whole foods more often than sugary drinks and refined snacks.
- Watch portion sizes—even healthy carbohydrates can raise blood sugar if eaten in large amounts.
- Regular activity, sleep, and taking prescribed medications (if needed) are also important.
If you have diabetes, prediabetes, or high fasting blood sugar, the best food choices can vary depending on your medications, kidney health, and goals.
