Title should be edited to include the date (2015), I wondered why it was being announced as something we didn't already know.

A study I read had two groups each eating a bowl of white rice (a high glycemic load food), except one group ate an apple fifteen minutes before the rice. Each group ate the same serving of rice, so the apple group was getting more carbs, more sugar, more calories. They found the apple group experienced less of a blood sugar spike from the rice. This changed the way I think about food and diet maybe more than anything other single food study.
