I am also thinking that there is a lot more processed sugars in our diet. Even bread these days has high fructose corn syrup in it.
I think we need to be looking at foods and going after the manufacturers. I believe we’re seeing so much obesity because of HFCS and MSG. I and my friends ate a ton of crap in high school and were couch potatoes. None of us were fat. I had one obese peer in my graduating class. My teen-ager eats a fair amount of junk, but it’s highly screened by me for plain sugar and no MSG. She’s a complete nerd, couch potato and skinny as a rail. We have scientists studying obesity using “MSG-mice.” That might be a bit of a “buy a clue, people.”
