The former British colonies/territories may be known for a lot of things, but in the nutrition world, I'm going to go out on a limb here and state that the Glycemic Index - GI - is the trifecta.
In Canada, David Jenkins pioneered the concept, for applications in diabetes treatment. This caused was picked up and concurrently championed in Australia by Janette (Jenny) Brand-Miller. A little late to the party, in one of the original Thirteen, David Ludwig took up the cause in the USofA. Are these the men and woman who made us fat?
Yes, that's pretty silly ... but no moreso than Adele Hite and others like her who in the same breath decry the error in equating correlation with causation as they point to plots like the one above to indict the low fat diet.
