I've actually had this discussion with by brother the other day.
I don't think the problem is how things are listed on labels or how big the font is, the problem is lack of education. I remember my bro and I were at ikea and he bought one of those chocolate bar blocks. He told me to guess how many calories and how many carbs/sugars are in it without me looking at the nutrition panel, obviously. I got the calories exactly spot on, and I think I was off on the carb content by 2 grams. That's what nutrition education does, it gives you the knowledge of how many calories/macros you're consuming. But the general public has no idea. They can't estimate caloric intake to save their life. And when they say "I eat 2000 calories" that could easily mean 4000 calories. My solution to this is very simple. Put nutrition classes into high school curriculum. When I was in grade 7 we had home ec, I don't think that's even offered anymore. There are two things high schools should be teaching people at the very minimum: nutrition, and how to file taxes. Those are the essentials for ANY adult. They need to know how to cook and they need to know how not to get fucked by the government come tax season.
