I don't have a view one way or another on the scientific accuracy of the report. Anecdotally though I live in Europe and gluten intolerance seems just a fraction of the issue it is in the USA. Just look at the gluten-free section in any supermarket, or ask in any restaurant for a gluten-free dish.
This topic surely deserves an extensive scientific investigation to 1) identify any statistically significant difference in gluten-free intolerance, 2) what root causes can explain the difference.
