What is the glycemic index and glycemic load of the most common American foods? Ever since the “Revised International Table of Glycemic Index (GI) and Glycemic Load (GL)” was published in the July 2002 issue of The American Journal of Clinical Nutrition and on my Web site, this has been one of the questions most commonly asked.
Carbohydrate content is the greater determinant of GL…
Until the editor of my forthcoming book asked me, I had begged off answering the question. But since he is paying me for the answer, his request was persuasive and you get the benefit of it.
Actually, the original list that I prepared for the book covered only the glycemic indexes of about 50 of the foods that Americans eat the most. They are divided into low, medium, and high, just like my editor requested.
It wasn’t until one of my faithful readers asked that I expanded this page to include glycemic load values as well. I thought at first that I would be able to simply combine the glycemic index and glycemic load values into one table.
But that turned out to be complicated. That’s because showing low, medium, and high index and load values in the same table requires all of nine separate divisions. A correspondent, Jon Landenburger, saw that the divisions would work much better as a two-dimensional table. He sent it to me, and I am pleased to include it in place of the one-dimension table I had originally prepared. The numbers after each food are its glycemic load and glycemic index respectively.
Roger Miller contributed a PDF version of the table. ’I wanted to print it without the rest of the page,’ he wrote. ’So I copied it into Word and simplified it to print better on my printer.” You can use his version at http://www.mendosa.com/gi_by_gl.pdf
This leaves the question of which is the more important—the amount of carbohydrate in a food or its glycemic index? It is an obvious question, because the glycemic load of a food is determined by multiplying its glycemic index by its available carbohydrate content per serving.
