Debunking The Blue Agave Myth

Posted: 02/15/10 12:50 PM ET

Agave syrup (nectar) is basically high-fructose corn syrup masquerading as a health food.

Sorry. Don't kill the messenger.

It's easy to understand how agave syrup got its great reputation. Even the word "Agave" has a fine pedigree, coming from the Greek word for noble. The blue agave species- considered the best for the making agave nectar -- flourishes in rich volcanic soil. (It's also the only variety permitted to be used for the making of tequila.) And extracts from the agave plant have been shown to have anti-inflammatory and antioxidant properties.

Unfortunately there's zero evidence that any of those compounds are present in the commercially made syrup.

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 (we'll get to that in a moment). 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 probably the single most damaging form of sugar when used as a sweetener. With the exception of pure liquid fructose, agave nectar has the highest fructose content of any commercial sweetener.

All sugar -- from table sugar to HFCS (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.

Research shows that it's the fructose part of sweeteners that's the most dangerous. Fructose causes insulin resistance and significantly raises triglycerides (a risk factor for heart disease). It also increases fat around the middle which in turn puts you at greater risk for diabetes, heart disease and Metabolic Syndrome (AKA pre-diabetes) .

And fructose has been linked to non-alcoholic, fatty-liver disease. Rats that were given high fructose diets developed a number of undesirable metabolic abnormalities including elevated triglycerides, weight gain and extra abdominal fat.

In the agave plant, most of the sweetness comes from a particular kind of fructose called inulin, which actually has some health benefits -- it's considered a fiber. But there's not much inulin left in the actual syrup. In the manufacturing process, enzymes are added to the inulin to break it down into digestible sugar (fructose), resulting in a syrup that has a fructose content that is, at best, 57 percent and -- much more commonly -- as high as 90 percent.

"Agave syrup is almost all fructose, highly processed sugar with great marketing," said Dr. Ingrid Kohlstadt, a fellow of the American College of Nutrition and an associate faculty member at Johns Hopkins School of Public Health. "Fructose interferes with healthy metabolism when (consumed) at higher doses", she told me. "Many people have fructose intolerance like lactose intolerance. They get acne or worse diabetes symptoms even though their blood [sugar] is OK".

Agave nectar syrup is a triumph of marketing over science. True, it has a low-glycemic index, but so does gasoline -- that doesn't mean it's good for you.

If you simply must have some sweets, a small amount of agave nectar every once in a while isn't going to kill you. Just don't buy into the idea that it's any better for you than plain old sugar or HFCS.

In some ways, it may even be slightly worse.

A few that are out there that are pretty yummy are:
palm sugar, still low glycemic,
powdered stevia now foods makes a great non bitter powder.
lo han
powdered dehydrated dates
lucuma (milder)

and plus it's still a much healthier alternative than a refined sugar, or true HFCS, or the splendas and aspartame driven sweetners for sure. Molecularly there's a little more wiggle room, not much, but a little.

Sometimes when it comes to sweet stuff it's not a matter of just ideal harmlessness, but more a matter of harm reduction for sweetner choices and uses.

I'd much rather see a diabetic using agave and cinnamon in their drinks than refined sugar any day.
Preferably I'd love to see them with massive amounts of amaylase and hemp protein as well to even out their insulin, but that's ideal. And ideal isn't always the starting place for people who have had a chronically poor diet and dietary choices.

I think what matters is how much of any type of sugar a person is eating on a daily basis. I eat less than 1 Tablespoon of agave a day. I think I'm quite safe in doing so.

I've always thought most health food were scams, how about "sugar in the raw", remember when that was supposed to be good for you, what a joke. The only diet anyone needs is 80% fresh or frozen veggies and meat as a seasoning. Drink V8, yeah I know there's an ocean of salt but the benefits of 8 boiled vegetables far out weighs the detriment unless you have a current heart condition. That's another point, don't diet for a disease you don't have or don't have a likely-hood of getting. Keep your calories under 2000 a day and you'll be fine, way better than many health food "junkies". My qualifications are I'm a 52 year old guy and I don't even take aspirin cause I'm healthy as a horse.

Peer-reviewed studies please.
10:37 AM on 02/17/2010
I should add that I think everyone should eliminate HFCS from their diet.
02:16 PM on 02/17/2010
Do you mean the health food people or the doctor who wrote this. Anytime a health food supplement has a peer review study done it's proven to be snake oil. Anyone for a ginko tab?

Agave "nectar" is a scam. Its not nectar. Its basically the same thing as HFCS, only worse.

The health food industry is run by morons. They totally fell for this crap.

Glad to see this information getting more play. I researched it last year and decided it was a marketing ploy but no one else agreed. I'm glad this is coming out. I've been using stevia for years and love it.

Well, so much for that, then. What I wonder is: what does Dr. Bowden use as (a) sweetener(s)?
01:17 AM on 02/17/2010
For what? Except for iced tea, I sweeten nothing. I like black coffee and what else is there to sweeten? (Stevia is an excellent choice for sweetening. One local cafe now provides it next to the toxin, splenda.)

Thats exactly right.

Eat less than 25 grams daily.
03:59 PM on 02/18/2010
No - too much of any kind of sugar is bad. There's some form of sugar in almost everything we eat that is also good for us. Fruits are good for you, but not too much fruit.

The best revenge is shopping for fresh non packaged foods. More natural fruits and vegetables. Americans do not eat enough salads and raw fruits and vegetables. Eat fruit for breakfast instead of high sugar cereals. You'll be surprised at your morning energy level. In addition, fruit is nature's cleanser.

Everything you say agrees with what I learned in my biochem courses. It makes complete sense. Thanks

I've found that Stevia is the only totally natural no glycemic sweetener for me to use. I bake with it and its fine.

i was JUST talking about this last night. I hate all sweeteners but i always knew agave was no good. Plus it's probably mostly sourced from the tequila industry run by Mexican drug cartels. Great article, I'll stick with apples and bananas.
