It is possible that sugar (particularly the wrong sugars or in excessive 
amounts) can alter gut permeability and increase the risk of an allergy 
or intolerance.

There is a difference between allergy and intolerance. Excessive sugar 
(sucrose/glucose) intakes have depleting effects on vitamin B metabolism 
(according to my RD sister, I don't know the mechanism myself), and may 
be bad for us because of that. Intolerance is any type of bad effect 
from a food, whereas allergy has a specific mechanism caused by IgE 
activation against a food component, usually a protein.

Physiology is so complex, I just love it, but have a hard time keeping 
up. The literature on mechanisms of allergy is incredible in itself.

It's so nice to picture you as I read your words, Karin!
