” American obesity is strongly related to carbs and sugar.”
A more correct explanation ...
” American obesity is strongly related to PIGGING OUT ON carbs and sugar.
In Italy where pasta and bread are a religion you don’t see a tenth of the obesity you see here.
Quantities and activity levels matter, and the Italians don’t look like the people of Walmart. The Italians also don’t have the same demographics we do.
Agree. But likely their bread and pasta is heavier whole grain.
That, and we have become sedentary.
