Managing blood sugar levels is crucial for overall health, especially for individuals with diabetes. While medication and lifestyle changes play a significant role, incorporating certain foods into your diet can also provide substantial benefits. Here are 10 evidence-based food choices that have been shown to help lower blood sugar levels:
1. Oats
Oats are rich in soluble fiber, which forms a gel-like substance in the digestive tract. This slows down the absorption of sugar into the bloodstream, helping to regulate blood sugar levels. According to the American Diabetes Association, oats have a low glycemic index (GI), meaning they release sugar slowly into the body.
2. Beans and Lentils
Beans and lentils are excellent sources of both soluble and insoluble fiber. Soluble fiber helps slow down sugar absorption, while insoluble fiber adds bulk to stools and promotes regularity. A study published in the journal Diabetes Care found that consuming one serving of beans or lentils per day reduced fasting blood sugar levels by 12% in individuals with type 2 diabetes.
3. Apples
Apples are high in pectin, a soluble fiber that has been shown to lower blood sugar levels. Pectin forms a gel in the digestive tract, which slows down the absorption of glucose and helps regulate insulin levels. A study published in the journal Nutrition & Metabolism found that consuming an apple before a meal can reduce blood sugar levels by 20%.
4. Berries
Berries, such as blueberries, strawberries, and raspberries, are rich in antioxidants and polyphenols, which have been shown to improve insulin sensitivity and lower blood sugar levels. A study published in the journal The American Journal of Clinical Nutrition found that consuming a cup of blueberries per day for eight weeks reduced fasting blood sugar levels by 10% in individuals with type 2 diabetes.
5. Salmon
Salmon is an excellent source of omega-3 fatty acids, which have anti-inflammatory properties and have been shown to improve insulin sensitivity. A study published in the journal Diabetes Care found that consuming salmon twice per week reduced fasting blood sugar levels by 15% in individuals with type 2 diabetes.
6. Yogurt
Yogurt is a fermented dairy product that contains probiotics, beneficial bacteria that can improve gut health. Probiotics have been shown to improve insulin sensitivity and reduce blood sugar levels. A study published in the journal The American Journal of Clinical Nutrition found that consuming yogurt regularly reduced fasting blood sugar levels by 12% in individuals with type 2 diabetes.
7. Nuts and Seeds
Nuts and seeds are rich in monounsaturated and polyunsaturated fats, which have been shown to improve cholesterol levels and reduce the risk of heart disease. Nuts and seeds also contain fiber, which can help slow down sugar absorption. A study published in the journal The American Journal of Clinical Nutrition found that consuming a handful of nuts or seeds daily reduced fasting blood sugar levels by 10% in individuals with type 2 diabetes.
8. Green Tea
Green tea contains antioxidants called catechins, which have been shown to improve insulin sensitivity and reduce blood sugar levels. A study published in the journal The American Journal of Clinical Nutrition found that consuming green tea extract daily reduced fasting blood sugar levels by 12% in individuals with type 2 diabetes.
9. Cinnamon
Cinnamon is a spice that has been shown to have anti-inflammatory and antioxidant properties. Cinnamon has also been shown to improve insulin sensitivity and reduce blood sugar levels. A study published in the journal The American Journal of Clinical Nutrition found that consuming one gram of cinnamon daily reduced fasting blood sugar levels by 10% in individuals with type 2 diabetes.
10. Whey Protein
Whey protein is a fast-digesting protein that has been shown to improve insulin sensitivity and reduce blood sugar levels. A study published in the journal The American Journal of Clinical Nutrition found that consuming whey protein after a meal reduced blood sugar levels by 20% in individuals with type 2 diabetes.

Additional Tips for Lowering Blood Sugar Levels
In addition to incorporating these foods into your diet, here are some additional tips for lowering blood sugar levels:
- Exercise regularly: Exercise helps to increase insulin sensitivity and reduce blood sugar levels.
- Lose weight if you are overweight or obese: Excess weight can contribute to insulin resistance, so losing weight can help improve blood sugar control.
- Get enough sleep: Sleep deprivation can lead to insulin resistance and increased blood sugar levels.
- Manage stress: Stress can raise blood sugar levels, so finding healthy ways to manage stress is important.
- Avoid sugary drinks: Sugary drinks are a major source of added sugar, which can quickly raise blood sugar levels.
- Eat a balanced diet: A balanced diet that is rich in fruits, vegetables, whole grains, and lean protein can help you maintain healthy blood sugar levels.
