There is absolutely no such thing as "chemical free". Water, lactic acid, casein, and so on, they're all chemicals, even if you have glorified them with a stamp that says "natural".
Your statement is true, but also useless, as in the true spirit of hacker culture, you're arguing semantics.
"Chemicals" when used in the context of food, means "artificial food additives".
You may disagree that such additives are bad for you health - but just how our early ancestors had low-lactose tolerance, we also have low tolerance for such additives. Maybe our children's children will be able to digest such foods better / more efficiently and without side-effects, but in the meantime there's a wealth of research showing strong links between food additives and increasing rates of cancer, obesity and diabetes.
