Seafood
Seafood is full of healthy fats, vitamins, minerals, protein, and antioxidants that can assist in lowering blood sugar levels. Protein helps prevent postmeal spikes in blood sugar levels, slows digestion, and enhances the feeling of being full. Regularly eating fatty fish such as sardines and salmon can also enhance blood sugar regulation. One study involving 68 obese subjects revealed that eating 750 grams of fatty fish weekly was linked to improved postmeal sugar levels in comparison to those who ate lean fish instead.
