fructo-oligosaccharides Saccharides are carbohydrates that include sugars (monosaccharides, disaccharides, oligosaccharides, and polysaccharides) FOS is a complex sugar that humans don't use directly as a nutrient (it is not broken down by digestive juices) But FOS does feed the GI tract's friendly bacteria, and the yeast can't eat it FOS is widely used in Japan in hundreds of food products, and studies there indicate that FOS can reduce high blood sugar and lower elevated cholesterol levels
Faint Object Spectrograph - - First Generation Spectrometer FOS was used to obtain spectra of very faint or far away sources FOS also had a polarimeter for the study of polarised light from these sources
