Fructooligosaccharides (FOS) are oligosaccharides (polymers that contain a small number of simple sugars known as monosaccharides) that occur specifically in fruits and vegetables including onions, garlic and bananas. We also often consume them as artificial plant-based sweeteners in drinks and desserts.
Fructooligosaccharides are used in the body as prebiotics, supporting the growth of healthy bacteria, and they may also protect the body against unhealthy bacteria. They have been linked with decreasing cholesterol levels and they are also a good source of fiber. On the flip side, an excess of Fructooligosaccharides can lead to abdominal problems such as bloating, gas and diarrhea.
