Fatty fish like salmon, mackerel, sardines, herring, anchovies, and trout are rich in omega-3 fatty acids. These fatty acids have anti-inflammatory properties and support heart health, which is critical for those with diabetes, as they’re at higher risk forcardiovascular issues. These fish are also high in protein, which helps stabilize blood sugar by slowing carbohydrate absorption. A seared salmon, or a salmon salad, is both nutritious and sumptuous.
