According to a new study by the Harvard School of Public Health, Americans who ate more white rice had a moderately increased risk of diabetes, but Americans who ate brown rice had a slightly lower risk. Given the glycemic load of white rice, this is hardly surprising. Just because you aren’t eating a candy bar, doesn’t mean what you’re eating doesn’t spike your blood sugar and insulin with all the attendant effects!
What I’d like to see is a study that asked the next logical question. That is, what about a diet that eliminates grains all together, but which still includes plenty of the fiber via vegetables, etc, that some are now getting from whole grains? That’s the Paleo approach at least.
