| because it is needed for hydrolysis reactions in digestion, with one water molecule needed for each residue of a protein, polysaccharide, or triglyceride you could eat pure salt, but i?m not sure if that really cles as food. i see you've never eaten the "french fries" in the greek restaurant i've just been to is water a foodstuff? salt might count? otherwise, pretty much nothing. everything you eat for calories is either carbs (carbon hexagons) , fats (hydrocarbon chains), or protein (complicated carbon chains) various minerals - salt is probably the most common thing i can thing of. water bentonite and kaolinite are edible clays that are used to stabilize and bulk out medications. :) unless |
