When we talk about what to eat, we must first realize who, or rather what, is eating. In fact, we, ourselves, are not really doing the eating. It is our cells that eat. When we put food in our mouth, that is just a continuation of the transport of food from the farms to the grocery store then into our mouth; the food is then transported to our cells by our bloodstream. It is our cells that really do the eating and that need the fuel and the parts to regenerate themselves. And cells can only eat two kinds of food for fuel. They can eat sugar or they can eat fat, and their health and your health will be determined by the primary fuel that they burn.
I have been asked to summarize in a single sentence what would best promote health. It is this: Health and lifespan is determined by the proportion of fat versus sugar people burn throughout their lifetime. The more fat that one burns as fuel, the healthier the person will be, and the more likely they will live a long time. The more sugar a person burns, the more disease ridden and the shorter a lifespan a person is likely to have.
