Food manufacturers have gotten so good at producing foods that we enjoy that we have a very hard time limiting how much we eat. Foods that are intensely rewarding, as many processed foods are, overpower our signal to stop eating. They trick our bodies into eating much more than we need.
Processed foods have a lot going for them. We like them so much that sometimes we even say we love them. They are inexpensive. They are convenient, requiring little if any preparation. You can find them just about anywhere. They are highly marketed and brightly packaged. There is no doubt that highly processed foods have become a staple for most Americans.
