There are many manufactured ingredients found in processed food, but these three are at or near the top of the list in terms of quantity:
- High-fructose corn syrup (HFCS)
Here are the numbers:
The average American consumes almost 152 pounds of sugar in one year. 
In 2019, the average American consumed about 37 pounds of HFCS. 
In 2021, the average US resident consumed about 130 pounds of flour. 
The winner is sugar. If you want to know who the loser is, here’s something to think about: Americans on average consume a total of 320 pounds of sugar, high fructose corn syrup, and flour every year, which is pretty close to a pound a day. And excess amounts of these particular ingredients are stored in the body as fat.
