Glutten intolerance is a very real thing and a serious issue for some people.
The incidence of true coeliac disease is between 1:1000 and 1:300 (depending on the country, as hereditary factors play a role). But the immune system and environmental factors also influence the disease.
The "gluten hype" does not make the diagnosis any easier, as recommendations are quickly made to avoid gluten. This delays the diagnosis of a possible coeliac disease, as the diagnosis is only possible with a gluten-containing diet.
The probability that both partners have a real coeliac disease at the same time is, in the worst case, (1/300*1/300)*100 = 0.001% (any question?)
