Lean meats are an excellent source of protein and can be a great addition to your diabetes-friendly diet. Lean meats such as chicken, turkey and lean ground beef are packed with essential nutrients like vitamin B12, zinc and iron, and are lower in saturated fat, making them a good choice for people with diabetes. Lean meats are also a good source of essential amino acids, which help keep your blood sugar levels stable and provide energy to your body. When incorporating lean meats into your diet, be sure to pick lean cuts, remove any visible fat and choose lean ground meats. Lean meats are also a great way to add variety to your meals while still keeping your diabetes under control.
