Answer: Fructose is a natural sugar present in fruits, fruit juices, certain vegetables, and honey. In these forms, fructose sugars can be part of a nutritious diet.
However, fructose is also a component of high fructose corn syrup, which manufacturers make from corn starch and add to foods such as sodas and candies. These foods are less nutritious, but a person can eat them in moderation.
Researchers are studying the links between high fructose foods and obesity, diabetes, and even some cancers. However, some evidence indicates that fructose is not necessarily a public health concern when a person consumes it in moderation.
