Their math is seriously flawed.
A full can of soda is 160 calories, which is 10 teaspoons of sugar.
That works out to 76 cups of sugar a year for 365 cans. Not 50 pounds, closer to 38 pounds. That’s for the FULL can.
Most soda manufacturers consider a 12 ounce can 2 servings.
Half that (18.93 lbs) is what 365 servings of soda/year works out to.
In other words, they are exaggerating by OVER 2 1/2 times the amount of sugar consumed by drinking soda.
IF they exaggerate so badly on such a minor thing, who could possibly take anything they say seriously?
Maybe they are using bigger cans............
