People with high blood sugar can generally consume yacon, but should do so in moderation. Yacon is a root vegetable rich in nutritional value, containing significant amounts of water-soluble fiber, fructooligosaccharides, various amino acids, and trace elements such as calcium, iron, and zinc. These components give yacon properties that help clear internal heat, detoxify the blood, promote metabolism, and enhance immunity.

Yacon has a low glycemic index, meaning it releases sugars slowly during digestion and may not cause rapid spikes in blood glucose levels. Additionally, yacon is rich in dietary fiber, which benefits intestinal health and delays carbohydrate absorption, potentially aiding in blood sugar control. Moreover, the dietary fiber in yacon may help individuals with diabetes feel fuller for longer, assisting in the management of both blood glucose and lipid levels.

Although yacon contains relatively low amounts of sugar, excessive consumption by individuals with high blood sugar could lead to excessive sugar intake, thereby affecting blood glucose stability. Patients with hyperglycemia should control their intake of yacon in daily life and avoid eating too much. At the same time, they should regularly monitor their blood glucose levels and follow medical advice for treatment.
