What is Food Intolerance?
Food Intolerance can be easily confused with food allergy or even some autoimmune disorder, as coeliac disease. Although food intolerance involves physical reactions and some of the same signs and symptoms as the others two disordens, symptoms are generally less serious and often limited to digestive problems. The symptoms may also last for several hours or days. In some cases of food intolerance, you may be able to eat small amounts of the offending food without trouble. But not all intolrances are treatable easily. The list of food intolerance can be huge, but the most commun are dairy products, grains and foods that cause intestinal gas buildup, such as beans and cabbage.

If the alcohol molecule cannot be effectively dealt with by the body, it can cause unusual symptoms to occur.
Fructose, fructan and other fructo-oligosaccharide intolerances
This intolerances are caused by a natural sources of sugar found in fruit, honey, and syrups as well as in table sugar and many processed foods and beverages. Those sugar are fermented by the flora in the lower bowel resulting in the formation of gas and chemical substances, such as short-chain fatty acids.
