You can not eat greasy hamburgers with cheese and french fries. For one thing the high temperatures destroys foods nutrition and second you have to consume all that grease.
If you bake fries you got something good to eat. If you bake meat you can cook the fat out of it. It's not only what you eat, but how you prepare it.
I can take sausage and boil it till I boil a lot of the fat out of it and it tastes a lot better.
People should eat more raw veggies like broccoli, cauliflower, tomatoes, cucumbers. Cooking food at high temperatures for long periods of time cooks all the nutrtion out of it.
Also, cooking in a microwave oven heats the food too high and destroys the nutriton and rips the molecules apart and you end up having to eat twice as much food to get enough nutrition. They say people started getting fat when microwave ovens were created.
