The best foods for high-protein diets are fish, seafood, chicken and other poultry, cheese, eggs and plant-based proteins, but monitor the amount of carbohydrates found in these foods, recommends the American Diabetes Association. Carbohydrates, found in breaded meats, beans and soy, convert to sugars, raising blood glucose levels.
Plant-based proteins are healthier options, but read the product package for a breakdown of the nutritional content. Foods, such as tempeh, tofu, nuts, nut spreads and edamame, are plant-based but vary in fat content, carbohydrate content and fiber. Hummus, falafel, lentils and peas may also increase blood sugar levels, explains the American Diabetes Association.
Eat fish and seafood at least twice a week for a high-protein diet, suggest the American Diabetes Association. Some fish are high in omega-3 fatty acids, such as salmon, sardines, rainbow trout, albacore tuna and mackerel. Other fish, such as tilapia, orange roughy, catfish, cod and flounder are also good sources of protein. Shellfish, such as clams, crabs, shrimp, scallops and lobster contribute protein to the diet, but breading and fat content may disturb blood glucose levels.
Include 2 to 5 ounces of meat as a part of a high-protein diet. Meats, such as beef, beef jerky, lamb, organ meats and veal, may contain fat but do not contain carbohydrates unless they are breaded. Limit the portion of protein to a one-quarter section of the plate and choose lean cuts of meat, advises the American Diabetes Association.
