I grew up with my brother and two sisters. We always were hungry and if you didn't want to eat, one of my siblings would take care of the problem. If there was something new on the table we hadn't seen before (happened quite a lot) we tried it anyway because if we didn't there wouldn't be any left.
I always thought kids would eat if they got hungry. Then, my youngest had a baby. My grandson was diagnosed with "failure to thrive" which is doctorese for "we have no idea." He wouldn't eat. He was never hungry. He was tube fed and seems to have gotten a little better but, remains a picky eater.
What the hell is the difference in our environment between now and when I grew up? It seems like every other kid today has some kind of allergy or food intolerance today. Lactose intolerance is very common. When I was little, there was exactly one kid in the entire school who was lactose intolerant. I always tried to sit next to him to get an extra milk.
Interesting story.
Failure to thrive, LOL. Gee, you don't think there could be environmental factors contributing to whacky conditions like this?
I agree though, in another few hundred years we're going to be a sick, obese, pill popping society if this keeps up. We're taking the wrong approach with our technology. The answers are in our heritage. Trying to fix everything with a pill isn't going to work.
It reminds me a lot of commercial agriculture, actually. Why try and fight millions of years of evolution? It works so much better when you use those millions of years of evolution to your advantage, see: permaculture, food forests, etc.
