Yikes! Maybe it's time I switch to using fresh tomatoes when making red sauce. It's not that hard to skin tomatoes anyways so maybe it makes sense to go in that direction, especially when they're adding that much sugar.
The cans each say 2.5 servings (to be clear, above I've done the math for the entire can), and I think for many foods, it will be the case that less than 1/2 the can is a serving. So there is something iffy about the comparison in the article (and 20 or 30 calories of sugar in a meal is not a huge concern for most people).
