Agave nectar syrup is basically high-fructose corn syrup masquerading as a health food.Agave nectar is an amber-colored liquid that pours more easily than honey and is considerably sweeter than sugar. The health-food crowd loves it because it is gluten-free and suitable for vegan diets -- and, most especially, because it's low glycemic. Largely because of its very low glycemic impact, Agave nectar is marketed as "diabetic friendly".What's not to like?
As it turns out, quite a lot. Agave nectar has a low-glycemic index for one reason only: It's largely made of fructose, which although it has a low-glycemic index, is now known to be a very damaging form of sugar when used as a sweetener.
Agave nectar has the highest fructose content of any commercial sweetener (with the exception of pure liquid fructose).All sugar -- from table sugar to high fructose corn syrup to honey -- contains some mixture of fructose and glucose. Table sugar is 50/50, HFCS is 55/45. Agave nectar is a whopping 90 percent fructose
, almost -- but not quite -- twice as high as HFCS.Fructose -- the sugar found naturally in fruit -- is perfectly fine when you get it from whole foods like apples (about 7 percent fructose). It comes with a host of vitamins, antioxidants and fiber. But when it's commercially extracted from fruit, concentrated and made into a sweetener, it exacts a considerable metabolic price.Rest of the story here.
