An overwhelming majority of what we eat is made from plants and animals. This means that composition of our almost entire food is chemicals from the realm of organic chemistry (carbon-based large molecules). Water and salt are two prominent examples of non-organic foodstuffs - which come from the realm of inorganic chemistry. Beside some medicines is there any more non-organic foods? Can we eat rocks, salts, metals, oxides… and I just don’t know that?
Compound is absolutely different than solution. That’s not a varying definition amongst scientists. Compounds have a meaning. There’s no ambiguity. Organic compounds have a very nebulous definition and there isn’t consensus. One such meaning does include most hydrogen carbon compounds. Others include carbon-carbon based compounds (but by definition, a compound requires more than one element, so diamond for example does not fit). You’re correct in pointing out nuance for the meaning of organic. You’re just digging a hole trying to defend the idea the other person’s statement could be interpreted as adding anything to water makes it organic.
