Is Agave Nectar Good for People With Diabetes?

Agave syrup

Agave nectar (or syrup) is made from the agave plant and is commonly used by people with diabetes and others that are interested in health and nutrition as an alternative sweetener. The agave plant is indigenous to Mexico and comes in many varieties. The blue agave plant is what tequila is made from. The least manipulated commercial form of agave nectar is made from extracts of the Salmiana agave plant and processed with enzymes derived from the mold Aspergillus niger (a process "generally recognized as safe" by the FDA).


Why Do People Use Agave?

Many people use it because they believe it has a lower glycemic index, which means it raises blood sugars at a slower pace. It is commonly used to sweeten beverages such as tea, or mixed into yogurt and hot cereal, like oatmeal.

Agave is 90% fructose and has lower glycemic index compared to most sweeteners, such as sugar, but its use comes with some caution.  When fructose is metabolized, most of it goes to the liver, instead of the bloodstream, where it could raise blood sugar. But, while it may not raise blood sugars as quickly, increased intake can elevate triglycerides, a type of fat in your blood that is associated with an increased risk of diabetes, metabolic syndrome, and heart disease. Therefore, if you already have high triglycerides or other risks of heart disease (which many people with Type 2 diabetes do), it is probably wise to choose a different alternative sweetener.

Also, if you are someone that likes to avoid high fructose corn syrup, you probably want to avoid agave syrup too, since it is almost 100% fructose.  

Additional Calories in the Form of Sugar Can Cause Weight Gain

When using sweeteners, one must always remember that additional calories can cause weight gain, which is an independent risk factor for diabetes and heart disease.

One teaspoon of agave nectar contains 5 grams of carbohydrate and 20 calories. If you use 1 tablespoon (the equivalent of three teaspoons), you are consuming 60 calories and 15 grams of carbohydrate - the same amount of carbohydrate in one serving of fruit or one piece of bread, without the added benefits of fiber and vitamins and minerals. If you have diabetes and are looking to lose weight, it is best to remove all calories from sugar, including sugary beverages and condiments, like agave, table sugar, maple syrup. If you must use sweeteners, you may want to use sugar substitutes instead. Studies have shown that reducing intake of sugars (which lowers calorie intake and promotes weight loss) can improve blood sugar and weight control.

What Is the Bottom Line?

Agave nectar isn't necessarily a better alternative to table sugar and other sweeteners. When it comes to weight and blood sugar control, all sugars should be taken into consideration. Weight loss can improve your blood sugars and lower your chance of heart disease. If you must use sweeteners, you may want to try alternative sweeteners that contain zero calories. If, on the other hand, you decide to use agave or other types of sweeteners, practice portion control.

The American Heart Association recommends that men limit their daily intake of added sugars to 150 calories, and women limit their daily intake of added sugars to about 100 calories per day.
