Greek Yogurt: High in protein and low in carbohydrates, Greek yogurt can be a satisfying snack or breakfast option that helps regulate blood sugar levels.

Incorporating Lean Proteins:

Include a serving of lean protein in each meal to promote satiety and stabilize blood sugar.
Choose baked, grilled, or steamed preparation methods to avoid adding unhealthy fats.
Combine lean protein with non-starchy vegetables and healthy fats for a balanced meal.

3. Healthy Fats: Enhancing Insulin Sensitivity and Reducing Inflammation

Healthy fats, such as monounsaturated and polyunsaturated fats, play a crucial role in blood sugar management. They improve insulin sensitivity, reduce inflammation, and support overall metabolic health.

Examples of healthy fat sources and their benefits:

Avocado: Rich in monounsaturated fats and fiber, avocado can help improve insulin sensitivity and promote satiety. A study in the Journal of the American Heart Association found that avocado consumption was associated with a lower risk of cardiovascular disease, which is often linked to blood sugar imbalances.
Nuts and Seeds (Almonds, Walnuts, Chia Seeds, Flaxseeds): These are excellent sources of healthy fats, fiber, and antioxidants. Almonds and walnuts have been shown to improve glycemic control and reduce the risk of type 2 diabetes. Chia seeds and flaxseeds are high in omega-3 fatty acids, which have anti-inflammatory and insulin-sensitizing effects.
Olive Oil: Primarily composed of monounsaturated fats, olive oil has been linked to improved insulin sensitivity and reduced inflammation. Using olive oil as a primary cooking oil can contribute to better blood sugar management.

Incorporating Healthy Fats:

Add avocado slices to salads or sandwiches.
Snack on a handful of nuts or seeds.
Use olive oil for cooking and salad dressings.
Incorporate chia seeds or flaxseeds into smoothies, yogurt, or oatmeal.

4. Whole Grains: Providing Sustained Energy and Fiber

Whole grains are a better choice than refined grains for blood sugar control. They contain more fiber, which slows down glucose absorption and provides sustained energy.

Examples of whole grains and their benefits:

Quinoa: A complete protein and a good source of fiber, quinoa has a lower glycemic index compared to other grains. This means it causes a slower and more gradual rise in blood sugar levels.
Oats: Rich in soluble fiber, oats can help lower cholesterol and stabilize blood sugar. Opt for steel-cut or rolled oats over instant oats for a lower glycemic response.
