I am an Electrical Engineer, not a chemistry major. But, I blame Corn Syrup. Why? When Coke was sweetened with cane sugar, it satisfies but you only can drink 1-2 bottles a day. Drink more and you WILL be sick
Eat too much ice cream made with real sugar, and you will puke. But you can eat gallons of ice cream sweetened with corn syrup and drink a case of Coke a day. In fact, you crave more of it, as you eat it. Unlike food made with cane sugar, which satisfies and warns you to stop.
You can trace the rise in weight gain and Diabetes to the US Govts dictate to use Corn Syrup in place of Cane Sugar without (or in spite of) safety research as to what it does do humans.
It stands to reason poor people are overweight due to consumption of cheaper, less healthy, processed foods.
I have worked to limit my consumption of HFCS and processed foods. Very hard to avoid completely.
Back in the 1950s, a kid would get a bottle of sugar sweetened Coke and the standard size was 12oz.
Now, it’s sweetened with HFCS and it’s what, 32oz?
The corn lobby is also why we have mandates for ethanol in gasoline, which has been a great destroyer of engine components.
