Salmon, sardines, mackerel, albacore tuna and other fatty fish boast high levels of omega-3 fats, which have been found to lower blood sugar levels and increase insulin sensitivity. Frequent fish intake has been linked to a decreased risk of chronic disease as well as improved mental health. Aim to consume at least two 3-ounce servings of fatty fish weekly. One serving of cucumbers (1/2 cup of sliced cucumbers) has just 2 grams of carbohydrates.
