No. As previously mentioned, I don't know enough about traditional foods there to make a judgment one way on the other. I am actually arguing that what my kids eat is an "upgrade" over McD and I assumed that if you think McD is no worse than diet of Bangladeshis then it is either the same or better since, possibly wrongly, I assume that parents universally want to improve their kids life.
Just to make more interesting. In the old country, the diet is heavy in fats of all kinds ( partially due to history of the location and, well, cold weather ). Despite its flaws, I would argue its still better than McD on most days.
