What a minefield the diet is. We think we are doing the right thing using fructose (fruit sugar) instead of other refined sugars. But are we?
Sensitivity to sugars like lactose, fructose and sorbitol is largely undiagnosed, but responsible for stomach bloating and intestinal distress in millions. These substances are used extensively in manufactured foods due to sweetening power and low cost. The genetic pre-disposition plays a role and more so the quantities ingested in combination with other elements.
The difference between Fructose intolerance and malabsorption is this:
Hereditary Fructose intolerance (HFI) is a quite rare genetic condition where the enzyme for breaking down Fructose is not produced. With HFI it is vital to observe a strict Fructose-free diet. Otherwise there is risk of serious disease including liver failure (sometimes fatal).
Fructose Malabsorption on the other hand is much more common and affects about 30% of people. Certain special cells (epithelial cells) on the surface of the intestine are not available to assist the digestive process.
Did you know that in experiments they inserted a camera down someone`s esophagus at the same time as putting sugar down they`re to see what it would do? The result was inflammation. Imagine your mouth tissues are the same soft vulnerable tissue all the way through your digestive tract. Constant bombardment of sugars not in their natural context i.e. in fruit, vegetables. Not only does this cause some of the above mentioned symptoms but also can cause valuable nutrient absorption to be impaired. When we get down to it, it is a matter of what form of sugar we are ingesting and how often.
