Regulate Blood Sugar

Both the beneficial fats and proteins found in sardines work to reduce the blood sugar absorption process. Sardines and other high-protein, high-fat foods can block the release of glucose (sugar) into the bloodstream, reducing the risk of blood sugar rises and crashes. People with diabetes, metabolic syndrome, or other illnesses linked to insulin resistance should pay particular attention to their intake of foods that contain the necessary fats and proteins.

Researchers fed the mice casein, protein sardine with high fructose protein, or sardine without high fructose in a trial on rats that were fed high fructose. Finally, they discovered that patients with metabolic syndrome may benefit from the diet (sardine protein), which avoided and reversed insulin resistance and oxidative stress.
