I think that is great advice, Grace. As a diabetic, I really like sugar substitutes, even with the potential long-term health risks. For typically healthy people, the natural sugars would be better for their bodies, but for diabetics sugar is sugar.
I should slowly wean myself from the sugar substitutes. Gosh, although I don't have a sweet tooth, per se, I do love sweetness in my food and cooking. I'm finding that as I age, however, my body is beginning to show signs of a lifetime's worth of not-so-great diet and exercise (or lack of!)
