Seafood

Seafood, such as fish and shellfish, is an excellent source of protein, good fats, vitamins, minerals, and antioxidants, all of which may help in blood sugar control. Protein is necessary for blood sugar regulation. It helps digestion and prevents blood sugar spikes after meals, as well as increasing feelings of fullness. It may also aid in the prevention of overeating and the reduction of extra body fat, both of which are necessary for maintaining healthy blood sugar levels.

Fatty fish, such as salmon and sardines, have been demonstrated to help control blood sugar levels. A study of 68 overweight or obese people found that those who ate 26 ounces (750 grams) of fatty fish per week had significantly lower post-meal blood sugar levels than those who ate lean fish.
