Agave is also fermented to make tequila.

It’s easy to see why agave nectar appears to be a smart alternative to table sugar, as it’s lower on the glycemic index (GI)—one indication of how a given carbohydrate is likely to affect the levels of glucose (sugar) in the blood.

However, this assessment isn’t as cut-and-dried as it may seem. If you have diabetes, you’ll want to understand how agave sugar really stacks up to sugar before working it into your diet or that of someone with the disease you care for.

Agave Nectar vs. Table Sugar

The differences between agave nectar and table sugar are negligible when it comes to calories, carbs and total grams of sugar. They diverge in terms oftypeof sugar and where each ranks of the glycemic index. It is these two factors that make agave nectar a questionable alternative to sugar.

Fructose

Fructose is a simple sugar (monosaccharide) found naturally in fruits and vegetables. It is relatively low on the glycemic index. However, when fructose is highly processed—as is the case with agave nectar—it can become problematic if consumed in excessive amounts.

Fructose is metabolized in the liver, which turns excess fructose into triglycerides—a type of fat—some of which can become trapped and lead to any of a number of chronic medical conditions. For example, large amounts of high-fructose corn syrup have been linked tonon-alcoholic fatty liver disease, insulin resistance, metabolic syndrome, obesity, and type 2 diabetes.

However, there is some controversy regarding the usefulness of the GI for controlling blood sugar. This is because the index doesn’t account for portion sizes of foods. What’s more, many of the factors that determine a food’s GI score (how the food is prepared, for example, or the laboratory in which it is measured) can be inconsistent.In other words, the fact that agave nectar is a highly processed sweetener containing a high percentage of fructose, paired with the possible inaccuracy of the Gi for determining a foods true potential affects on glucose levels, makes it a less viable alternative sweetener for people with diabetes than it appears to be at first glance.Ups and Downs of Blood Sugar in DiabetesA Word From VerywellIf you have diabetes, it is advisable to reduce your intake of all types of sugar, including agave.
