We're WAY too hung up on reading labels. I rarely do. Simply put, if you're having to read labels all the time, you're eating way too much processed food.
I buy canned goods ~ but they're generally limited to three categories: broths, diced and stewed tomatoes, and beans. The only food items I buy in a box are oatmeal and pasta. Because I buy these items frequently, I pretty much know what's in them.
Calculating all that stuff, along with grams of fat, cholesterol and carbs makes eating pure works ~like taking a life-long math class! The reality is that many of those who so diligently do that by day, end up raiding the cupboards and refrigerator for the bad stuff at night. If you're not eating enough fruits, nuts and vegetables ~ you're body simply isn't every nurtitionally satisfied!
To make life easier, and eating more enjoyable, eat more fresh stuff than processed, packaged food ~ and move around more. And make it a practice to ask yourself what you are really hungry for when those cravings hit.
Maybe it's not food, at all!
