I have never been a drinker nor smoker. Always fit and watched my diet.
(Although it was high in grains and carbohydrates (fruits) not much meat).
I
was diagnosed with Mild UC after a bug infection. Now it seems under
control, but I am eating more meat (fish, chicken, red meat) less fruit
and
more vegetables and staying of any processed foods. For me it may have
been
an over response to a bug, but this has not been proven so I'm sticking
with
a diet change.

1) If something like CD decreases successful procreation it would
decrease in time. Note the “in time” part, that could take
generations. And some cases of CD strike in the mid to late 40s, a
time when many people have already had children.
2) Not everyone considers it an autoimmune disease. From my reading
the current mainstream opinion is that it is an immune dysfunction
disease.
3) At its simplest, evolution is survival of the fittest, that is,
those who are fittest for their environment have more offspring. If
the environment changes, the the genes most fit for the population
can change. It is possible that IBD is caused by an aggressive immune
repose to some trigger. If this is true, then for much of humanity's
history, it may have conferred a benefit on those carrying the
genes. The “hygiene hypothesis” suggests several immune diseases may
be a result of modern hygiene (not enough parasites to keep our immune
systems busy).
4) CD could be increasing due to more people moving into modern
living conditions, if something in those conditions triggers it. A
better understanding of the disease and better methods for detecting
it could lead to what looks like an increase but is just better
diagnostic techniques. Better medical care might explain the increase
too; people that would have died young without children get care and
go on to have children of their own.
