You can eat egg whites or egg substitute. You should stick to baking your own cakes and cookies at home so that you do not eat sweets and baked goods that are commercially made. Commercially baked goods contain many things that homemade goods do not, such as cholesterol and a lot more sugar. Try to eat only sherbet and sorbet instead of ice cream. You could also eat frozen yogurt.
Ice cream contains a lot of cholesterol.
You should only use unsaturated oils and butters when cooking and eating. Using excess saturated fats lead to heart disease. By following these recommendations, you can be assured that you are greatly reducing your risk of getting heart disease. Just take the changes slowly. You do not have to do anything drastic, changes will not occur overnight, just take a couple of weeks to get used to your new style of eating.
