I have four of Dr. Sears's books. Sometimes he suggests using fructose, granulated or liquid, as a sweetener. In the past couple of years, I have heard that fructose can be harmful and my favorite health food store, Earth Fare, stopped carrying the product. I'm confused. Please advise.

You might be confusing fructose with high fructose corn syrup. That sweetener is definitely bad!

I have not really researched plain fructose, but I think I have heard some scuttlebutt about some negative aspects of it. However, in the Zone, I find very little use for it, anyway!
