I’m just messing around 
Because Americans allow it to be genetically modified
“Correct” according to who? Carbs and protein are macronutrients that are found in varying degrees in all food types, they are not food groups. Same with “fats and sugars”.
WHO, UK NHS
NHS defines food groups like basically every other government health organization, including the US FDA. See links for comparison. Anyway, I didn’t come here to argue about international nutrition guidelines so have a nice day!
Close but the eatwell is a guide, same crap as myplate, not a classification. I can’t be arsed to look for it again but I’m sure you can see there are big differences even between those 2 you linked.
Don’t get me wrong but I live long enough on this world to know if something is “American scientist” or “American research” or similar, it’s 99% nonsense. Same with Aussies.
like many other aspects the AI is sh*t… hopefully one day they’ll address these issues
