Cat, a very thoughtful and thought-provoking response; thank you!
Personally, I have my own theory about why there is so much obesity nowdays (the spell check doesn’t like that word, but tough!). Part of it is the fast food phenomenon, but there’s this little ingredient that’s been in a lot of our food since 1975, called HFCS - High fructose corn syrup. Back when I was growing up, there was ONE obese person during all my years in school, K-12. ONE! There were some “chubby” people, but nothing to the extent of the problem now. You had to work at it to be obese!
The corn industry will tell you differently, but there is research that shows that little artificial molecule does things in our brains - it turns off the natural appetite suppressant leptin so that no matter how many calories we eat, we don’t feel satisfied. That mechanism alone is enough to cause people to eat far more calories than they can ever burn off in a day. Personally, I believe that some people are very susceptible to the effects of HFCS and these are the ones who gain ENORMOUS amounts of weight, somewhat like what happened to Native Americans when the settlers gave them alcohol (meaning they had bad effects, not that they gained weight!).
Yes, our lives are somewhat more sedentary, but we also have more leisure time available for all sorts of activities and sports. I just don’t see that as being the cause for this epidemic of obesity. I think we’ve been playing with our brain chemistry to make foods so sweet and the high intake of this particular molecule has been VERY destructive. I can tell you that in our household, I’ve seen my husband’s use of ketchup go down a LOT since I stopped buying the stuff with HFCS in it. We used to drink soda, back in the day, but it was made from cane sugar, not HFCS. And we stopped when we had one! Not 32 oz. per serving! Natural foods just work in our brains. Artificial stuff tricks your brain.
Well, that’s TRJ’s nutritional and food science lesson for the day, kids. Get rid of HFCS and I would be willing to bet my car (which I love a lot) that the obesity rate will start to go down on its own.
