Let us consider an ongoing experiment in discovering the relationship between a vegetarian and/or near vegetarian diet and type 2 diabetes, India. In urban areas the rate is 9 percent and rural 3 percent, with an over all rate of about 4 percent, and growing in India. In the US, mostly urban, it is about 5 percent. The rate of pre diabetes is also higher. Clearly there is something other then simply vegetarian vs. not vegetarian diet that is at hand. See: http://www.diabetesindia.com/diabetes/itfdci.htm from the page: In keeping with the scenario of most developing countries, India has long passed the stage of a diabetes epidemic. The problem has now reached, in scientific language, "pandemic" proportions. To put it simply, it has crossed the dividing line in which it is a problem associated with individuals, no matter how large this number may be, and is now a very large public health problem, growing astronomically year after year.
