However, studies have revealed that increased consumption and increased portion sizes may be the reason that we and our children are ingesting far too much sugar. Between the late 1970s and the late 1990s, a 123% increase in soft drink consumption among children and adolescents was reported in the US.
Some naturally occurring sugars are not as sweet as sugar: fructooligosaccharides (FOS) are also used as sweeterers, they exhibit sweetness levels between 30 and 50 percent of sugar and they are excellent substitutes for sugar and fat.
Banana has been indicated as a good source of fructooligosaccharides. In a full-ripe stage, 1-kestose, a fructooligosaccharide, was accumulated in all tested bananas with amounts between 297 and 1600 µg/g of dry matter.
