They grew up eating junk food, processed foods, fast food. My sons are 40 and 42 and have no chronic health issues, but they grew up on home cooked mostly from scratch foods, and I watched their sugar intake at home. Their children are a whole different situation, they range from 14 to 3 and neither wives cook. So they eat junk food, processed foods, and fast food. I pray for them, but no one listens to me about food.
As you state, nobody listens though. Nobody wants to listen because that would mean getting off the living couch and then spending an hour or two in the kitchen making something healthy.
It's easier to just "heat and serve."
