When plants undergo photosynthesis, they break the oxygen off the CO2 molecule and create carbohydrates. At this point, the CO2 molecule ceases to be. So to say that there is CO2 in food is incorrect. Our bodies recreate the CO2 when recovering energy from those carbohydrates.
I said food was made from carbon dioxide and water, and repeatedly explained the process I was referring to. I never once said carbon dioxide was "in" food, although even if I did I don't think it is this easy to misunderstand what I'm saying.
You said it’s made “of” carbon dioxide, not “from” carbon dioxide. Different prepositions carry very different meanings in this context.
I’m glad we agree on the process. Your initial statement was imprecise and led to confusion.
