Yes, you can eat meatballs on a diet. Like anything in life, moderation is key. While meatballs contain a lot of essential nutrients needed for health, eating too much of one type of food is not great for anyone. Here are some tips for eating meatballs on a diet.  The individual ingredients will determine the overall health of the meatball. Many store-bought varieties may contain a lot of sugar, salt, and preservatives so make the recipe at home when possible.  Look for recipes with lean ground meat like this one. Meatballs that are baked or grilled, contain herbs and spices, vegetables and other high-fiber ingredients also increase the nutrition of the meatball. The sauce you eat with also will have a bearing on the health of the meatball so balance your meatball with a healthy side such as steamed veggies, salad, whole grain veggie-based gluten-free pasta, and lean proteins.
