I've heard the argument that it really doesn't matter what you eat as long as it's filling. Really? If that were the case, then by far the best and cheapest route would be to shred some pasteboard, sprinkle it with some salt and sugar, then eat to our heart's content. BUT WAIT! Much of our processed food is little more than that. We would never fuel our car with water and expect it to run well; since our bodies are much more complex organisms than a car we can't it expect to fuel them with food void of nutrition and achieve optimal performance.
What our bodies need is nutrition, not volume. Nutrient dense food is a little harder to find, but well worth the search, and the price. Why? It's what our bodies want and need. My physician, Dr. Ben Edwards, calls it "God Food." Many authors in the health debate/literature are now calling it "real food."
So, what is real food? It's food that is in the form closest to what it looked like when harvested. It's food that is raised with zero or minimal chemical inputs (e.g., pesticides, herbicides, fungicides, antibiotics, hormones, etc.). It's food that hasn't been sliced, diced, mushed, crushed, frozen, boxed, waxed, and/or colored. It's food that has been raised in healthy, living, vibrant soil.
Moreover, we're learning now that we should probably consume about half of that real food in raw form, if we're seeking maximum nutrition. Real, nutrient-dense food is pretty much all we need to live long and healthy lives.
Come on in, the water's fine...
