Why are minorities more likely to be obese and have diseases?

[sethnintendo]

I was just pondering this question.  It is pretty obvious and clear that the minority population in the USA is the most obese and most prone to disease (diabetes, overweight problems, etc).  I will not make this that much of an op for now but if you really want I can bring up countless study after study that easily shows these problems are more prevalent in the minority population.  I was wondering why this was?  Is it diet related?  Did they become too Americanized?   Sure there are plenty diseased overweight white people but there are even more in the minority population.  I see a health care crisis (already happened) striking the USA especially with high concentration of obese and diabetic Hispanics.  I am not racist; I am merely stating facts.  So tell me why is this the case...
