That sounds like a tough one! So - a question for you - Is the allergy triggered by natural fructose, like you'd find in fresh fruit or is it more the added fructose syrup that seems to be in pretty everything sweetened, these days?I called it "fructose intolerance" only because it's easier to equate it to lactose intolerance, but the proper name is "fructose malabsorption."
It's when the cells in the intestines are not able to digest or absorb fructose properly, and causes much the same symptoms as lactose intolerance.
"Fructose intolerance," on the other hand, is a rare genetic condition where the body lacks the enzyme aldolase B, which is needed to break down fructose in some crucial metabolic pathways.
It is much more serious and can lead to liver failure or death.
