Try adding more foods to your diet for more variety and more nutrients. There are endless healthy options you can make when you have access to many different types of foods. variety keeps you from getting bored with your diet and also prevents you from turning to unhealthy food options.
You should not totally avoid red meat. While it is generally higher in saturated fat, you can cut this by removing its skin. Opt for leaner cuts of red meat such as beef, pork and chicken. They still contain a vast amount of protein and as long as they are skin-free, the fat is removed or reduced, and nothing unhealthy is added to them, they make healthy additions to any diet.
Try to eat more white meat in your diet everyday. Most protein comes from animal fat and this kind provides the least amount versus red meat. You can find tasty white meat in turkey, chicken and even pork. Add these to items such as sandwiches, salads, stews, soups, etc; the possibilities are endless.
