> the average American now consumes about as much added sugar as the average American did in 1970--yet their waistlines are not remotely comparable.

But people don't become obese overnight. People ate much more sugar in 2000-2010, and those people, if not dead now, are still contributing to the obese rate today.

Also this graph shows people are still eating more sugar in 2021 than in 1970. Just not as much as in 2000.

No one says sugar is the only reason causing obesity. But this graph doesn't debunk the correlation between sugar and obsesity either.
