I'll check on occasion. But I rarely buy items that would require checking (which I believe would mostly be processed foods, like chips, cookies, crackers, frozen foods, drinks, etc.). I try to avoid having to worry about it buy purchasing organic cookies and such, but I still check with those the first time around, lol. Only for ingredients, I'm not a calorie/fat counter. I do look for sodium though, I can't handle overly salty foods, nor do I want to consume them anyway
