The USDA food pyramid is a joke.
Think people: how is it animals don’t need dentists?
How could it be that humans alone evolved with the first means of injesting sustenance—teeth—that are quickly destroyed by the very food they eat?
Unless we did not evolve to eat such food.
And if we’re eating food that rots our teeth, who knows what other damage it’s doing to our insides which are hidden from view.
Sugar and such “foods” as bread, pasta, dairy should all not be eaten.
My rule: if it comes in a bag or a box, it doesn’t go into my mouth.
Animals do get cavities. They also die younger than humans.
