'What is "protein" when a "carbon" "element" does not exist?' Literally none of the compounds "science" claims to be in food is in the form which is "discovered" by a lab process, zero. Compounds like: lectins, peptides, protein, caffeine, vitamins, bioflavonoid, salicilates, alkaloids, etc... Nobody knows what's in food by way of science, nobody! The food–calorie model is wrong. We imbibe and integrate the food we eat as-is into our bodies; there is no food to energy conversion. ATP molecule is science fiction. "An average cell...uses about 10 million ATP molecules per second" Just make up the science. https://www.verywellhealth.com/atp-6374347 The article says ATP can make DNA and RNA, can be neurotransmitter, send messages (what does means at the cell level?), muscle contraction, protein synthesis. Basically everything-another holy molecule, just like the DNA. Spin science molecules forever. Digestion is a myth - a jigsaw puzzle breaking apart, with you incorporating the pieces into your puzzle, is more like it. It is based on assumption.
