Is Yacon Syrup Safe for People with Diabetes?

Yacon syrup is a natural sweetener derived from the roots of the yacon plant (Smallanthus sonchifolius), a tuber native to the Andes mountains in South America. Known for its mild, sweet taste and low-calorie content, yacon syrup has gained popularity as a potential alternative to sugar and other high-calorie sweeteners. Its unique composition of fructooligosaccharides (FOS)—a type of natural sugar that the body cannot fully digest—makes it particularly interesting for those looking to manage blood sugar levels, especially individuals with diabetes.

Diabetes is a condition characterized by elevated blood sugar levels, which can lead to serious health complications if not properly managed. People with diabetes often need to be careful about their intake of sugar and carbohydrates, as these can cause spikes in blood sugar. With the rise of natural sugar alternatives, many people are curious about whether yacon syrup is a safe option for managing blood sugar levels and if it can offer any health benefits.

In this article, we will explore what makes yacon syrup unique, its potential benefits for people with diabetes, and any safety concerns associated with its use.

What Is Yacon Syrup?

Yacon syrup is made by extracting the juice from the yacon root and then concentrating it into a thick, sweet syrup. The taste of yacon syrup is often compared to that of molasses or caramel, and it is commonly used as a sweetener in beverages, baked goods, or as a topping for yogurt or oatmeal.

What makes yacon syrup different from other sweeteners is its high content of fructooligosaccharides (FOS), a type of prebiotic sugar that the human body is unable to fully digest. FOS acts as a fiber, passing through the digestive system without being broken down into simple sugars, which means it has little to no effect on blood glucose levels. This characteristic has led to the belief that yacon syrup might be a good option for people with diabetes.

In addition to FOS, yacon syrup contains inulin, a form of soluble fiber that further supports digestive health and may help regulate blood sugar levels. The syrup is also low in calories, containing about 20 calories per tablespoon, compared to 60 calories in the same amount of traditional sugar.

Can Yacon Syrup Help People with Diabetes?

Yacon syrup has gained attention as a potential diabetes-friendly sweetener due to its low glycemic index and its ability to promote better blood sugar control. Here are a few key reasons why yacon syrup might be beneficial for people with diabetes:

1. Low Glycemic Index

The glycemic index (GI) measures how quickly a food raises blood sugar levels after consumption. Foods with a high GI cause rapid spikes in blood glucose, while those with a low GI have a slower, more gradual impact. Yacon syrup is considered a low glycemic index sweetener, meaning it is less likely to cause rapid blood sugar spikes compared to regular sugar or high-fructose corn syrup.

Since yacon syrup is composed primarily of fructooligosaccharides, which are not fully digested, its impact on blood sugar is minimal. This makes it a potentially safer sweetener option for people with diabetes who are trying to avoid blood sugar fluctuations.

2. Fructooligosaccharides (FOS) and Blood Sugar Regulation

The main active component of yacon syrup, fructooligosaccharides (FOS), behaves differently from regular sugars like glucose or sucrose. Because FOS is not absorbed into the bloodstream, it does not contribute to a rise in blood sugar levels. Instead, FOS functions as a prebiotic, feeding the beneficial bacteria in the gut, which can have positive effects on digestion and metabolic health.

Studies have shown that FOS can help improve insulin sensitivity, making the body more efficient at using insulin to regulate blood sugar levels. This may be particularly beneficial for individuals with type 2 diabetes, who often struggle with insulin resistance.

3. Potential for Weight Management

Weight management is a crucial aspect of diabetes control, as excess body weight can exacerbate insulin resistance and lead to further complications. Yacon syrup has been studied for its potential role in weight loss due to its low calorie content and ability to promote feelings of fullness.

In one study, overweight women who consumed yacon syrup experienced significant weight loss, reduced waist circumference, and improved insulin sensitivity over a period of time. While more research is needed to confirm these effects in larger populations, the findings suggest that yacon syrup could support weight management—a key factor in controlling diabetes.

4. Digestive Health Benefits

Yacon syrup’s high content of fructooligosaccharides and inulin not only supports gut health but may also help regulate blood sugar levels indirectly. FOS acts as a prebiotic, feeding the beneficial gut bacteria that help maintain a healthy digestive system. A balanced gut microbiome has been shown to play a role in regulating glucose metabolism and improving insulin sensitivity, both of which are important for diabetes management.

In addition to promoting a healthy gut, yacon syrup can help alleviate constipation, which is a common issue for people with diabetes, due to its mild laxative effect.

Safety Considerations for People with Diabetes

While yacon syrup offers several potential benefits for people with diabetes, there are a few considerations to keep in mind when using it as a sweetener.

1. Moderation Is Key

Although yacon syrup is lower in calories and has a lower glycemic index than sugar, it is still important to use it in moderation. Overconsumption of yacon syrup, especially in large quantities, can lead to digestive issues such as bloating, gas, and diarrhea due to its prebiotic content. For individuals with diabetes, managing portion sizes is crucial to ensure that blood sugar levels remain stable.

2. Impact on Digestive Health

As yacon syrup contains FOS, it acts as a natural fiber that can promote digestion. However, for some individuals, particularly those with irritable bowel syndrome (IBS) or sensitive digestive systems, the fiber content may cause discomfort if consumed in large amounts. It’s recommended to start with small amounts of yacon syrup and gradually increase the dosage to see how your body reacts.

3. Potential Interactions with Medications

If you are taking medications for diabetes, it’s important to monitor your blood sugar levels when incorporating yacon syrup into your diet. While yacon syrup has a low impact on blood sugar, it’s still essential to consult with your healthcare provider before making any changes to your diet, especially if you are on insulin or other diabetes medications.

4. Not a Complete Substitute for a Healthy Diet

Yacon syrup, like other sugar substitutes, should not be seen as a miracle cure for diabetes. While it may help manage blood sugar levels and reduce calorie intake, it’s important to maintain a balanced diet rich in whole foods, lean proteins, healthy fats, and fiber. Using yacon syrup as part of a healthy diet can contribute to better overall blood sugar control, but it’s not a replacement for proper medical care and lifestyle changes.


For people with diabetes, yacon syrup can be a safe and potentially beneficial alternative to traditional sugar and high-glycemic sweeteners. Its low glycemic index, high content of fructooligosaccharides (FOS), and ability to promote digestive health make it an appealing option for those looking to manage blood sugar levels and support overall metabolic health.

While yacon syrup offers several potential benefits, including improved insulin sensitivity, weight management, and gut health, it’s essential to use it in moderation to avoid digestive discomfort. As with any dietary change, it’s recommended to consult with a healthcare professional before incorporating yacon syrup into your diabetes management plan, especially if you are taking medication or have specific health concerns.

Incorporating yacon syrup into a balanced, diabetes-friendly diet may help you enjoy sweet treats while keeping your blood sugar in check and supporting your overall health.
