Hereditary Fructose Intolerance (HFI) is inherited through autosomal recessive traits. [1]

HFI also called Fructose Intolerance (FI). It is said to be rare, but there are many indications that FI is more common than many sources indicate. At the end of this article you will find sources to various ways to diagnose fructose intolerance through the regular medical system as well as the naturopathic system.

Fructose intolerant people have difficulties in several areas: A. digestion, B. liver damage, C. kidney damage, and D. blood sugar irregularities, and it is not limited to those. At this present time, a cure is not known, and those with fructose intolerance need to work around it and remove fructose from their diets. Fructose comes in many forms. Primarily, fructose is the sugar found in fruit; however, it is found as an additive in many processed foods you will find in the regular grocery store such as soda pop, jams and jellies, syrups, and boxed food.

A. People with HFI/FI lack an enzyme called Aldolase B to break down fructose during digestive processes. [1] [17] The purpose of the enzyme Aldolase B is to digest fructose, but when the body is missing this enzyme, fructose builds up in the liver, causing damage, and additionally malabsorption results in the small intestines. [2]

Without proper digestive enzymes, toxic by-products and fermentation result, poisoning the entire body system.

One source which cited a scientific study based on the results of a hydrogen breath test to test for fructose intolerance states that up to 30% of Irritable Bowel Syndrome sufferers have fructose malabsorption and that many IBS patients had problems digesting fruit and other foods. [3] That's significant.
