I see; thank you !
So the idea is to meet guidelines? Or maybe because sugar is more likely to be hidden in a childs diet. I was wondering if the idea was that adults need more “sugar” than children, or that by limiting sugar early you might effect their future choices. Now I’m wondering if there are parallel guidelines regarding sugar for adults, but they probably don’t specify sugar.
ETA Here are some recommendations for “added sugar” from the American Heart Association. Interestingly it does not differentiate between refined and other added “sugars”.
Here’s USDA which mentions “the dreaded” school meals and “grain based deserts” like breakfast bars.
One more! ADA
I guess these are better on the “healthier” thread.
