Whether artificial sweeteners are the answer is less clear, given lack of evidence that increased use of artificial sweeteners leads to reduced sugar consumption.
But if you're not, or can't... well. Simple lack of availability will be a major hurdle.
And to make use of all that production, they make sugar out of it. High-fructose corn syrup to be exact. And then they put it EVERYWHERE because it's so cheap - because of the overproduction.
