The good news is that type 2 diabetes can be prevented by eating healthy foods. Insulin-resistance happens over time if you eat too many processed carbohydrates, such as bread, pasta, cereal, cookies, and French fries. Anything that is high in sugar or carbohydrates has the potential to make you insulin resistance. You can still eat carbohydrates, but you should just be careful with the type of carbohydrates you consume.
Rather than cereal for breakfast, have eggs. Eat almonds for a snack instead of popcorn. Skip the sandwich at lunch for salad with olive oil vinaigrette dressing. Have sweet potato instead of French fries or white potatoes.
The key to preventing diabetes is to eat a variety of real foods, including real protein, vegetable carbohydrates, and healthy fats.
