I agree. People need to be educated , so they understand why they need to eat differently. Part of this is because of a lot of misinformation or product labels that make "healthy" claims that aren't true. It's hard to know what is true if you don't dig a bit.
I just know that since I've adjusted the kinds of food I eat, I actually eat more food and weigh less. It's not that people gain weight and develop certain health conditions because they are just greedy or something. It's impossible to stop when you have a bad diet.
The food is chemically engineered these days and our bodies do not recognize what we are putting into it. Body confusion and “healthy” labels usually are not healthy. However, people do not want to do the work of research and educating themselves these days.
