Haven't the British adapted a diet rich with curried foods due to their historical relationship to India? How would such a study reflect over there? Determining the impact of such spices when introduce to an Anglo-Saxon population would be very useful before drawing any sort of conclusion based upon this particular study.
Seems to me that this should have been the next step.
Unless of course, the media was trying to invent news. But they wouldn't do that, would they?!? ;P
