It is an established fact that if you want to eat healthy and be fit, you should do your own cooking. No restaurant really cares for your health. Even food sold at a premium as "healthy food" is bad for you. So if you don't cook, start doing it immediately. And while you are at it, here are a few tips that will make your food healthier. 1. Increase the content of vegetables in your food and reduce the content of meat, especially red meat. 2. Buy whole wheat bread or multi grain bread instead of eating white bread.
