NEW YORK (AP) — Sugar is the latest nutritional enemy, but saying how much of it Americans are consuming is complicated.

Government data shows the amount is down from its high in 1999, and a big reason for the decline is the drop in soda consumption, which is sweetened with high-fructose corn syrup. Government figures are estimates, so it’s an inexact science.

But the data and industry trends indicate we’ve actually made progress in cutting back. On average, Americans’ total consumption of caloric sweeteners like refined cane sugar and high-fructose corn syrup is down 15 percent from its peak in 1999.

Soda consumption started falling around the same time, and is down 24 percent since 1998. That’s according to industry tracker Beverage Digest.
