Do you pump diesel into your petrol-run car? I hope not, that would go against the car’s “instruction manual” and destroy it!
Similarly, are you filling your body with foods that you need, as recommended by national dietary guidelines? The “dietary” instruction manual (aka national dietary guidelines) for your body to function properly is readily available, free for all. If you’d read the instruction and care manual before using a new washing machine, or putting new clothes to wash, why not do the same for your body?
Probably only because it seems we can get away with it. But are we really? While an overused washing machine may stop spinning, and a silk blouse may tear, our bodies undergo lots of wear before eventually shutting down. Think about the diseases that lead to death these days, such as stroke, diabetes, kidney disease, liver disease, and cancer. They’re different from the diseases that used to kill our ancestors—quick deaths from infections due to poor sanitation or lack of medical treatment.
