Processed foods challenge body processes (not all processed foods are challenging to the body, but the ones that are good for the body are in the minority). The foods being discussed here are the ones that contain the ingredients that are known to be harmful, but people eat them anyway.
These foods should be limited to never. Really!
Food is not the only damaging thing to people; emotional damage can be more harmful than eating toaster pastries. Nonetheless, the better the food we put into our bodies, the more chance of physical and emotional balance.
