Inulin FOS (Fructooligosaccharides) is a type of prebiotic fiber that is not digested by the human body but instead serves as food for the beneficial bacteria in the gut. In general, inulin FOS is not expected to significantly increase blood sugar levels.

Although inulin FOS is a type of carbohydrate, it has a low glycemic index, which means it is digested and absorbed slowly by the body, resulting in a gradual and sustained release of glucose into the bloodstream. This slow and steady release of glucose is unlikely to cause a significant increase in blood sugar levels, especially when consumed in moderate amounts.

However, individual responses to inulin FOS can vary depending on several factors, including the amount consumed, individual tolerance, and existing medical conditions. Therefore, it is always a good idea to consult with a healthcare professional before incorporating inulin FOS into your diet, especially if you have diabetes or other blood sugar-related conditions.
