A tablespoon of pure white sugar.

A Snickers bar.

A banana.

And a slice of whole wheat bread.

If I were to ask you which of the edible items above causes the greatest surge in blood sugar, which would you choose?

My guess is that most people would pick the Snickers bar.

It’s a candy bar, and candy bars are sugar bombs that lead to diabetes, right?

Yup, but…

The answer is actually the one you likely least expected — the slice of whole wheat bread.

I kid you not. If you take a look at the glycemic index (GI) — which measures how quickly blood sugar rises after eating particular foods — you’ll find that whole wheat bread has a GI of 71.

Sugar – 68. Snickers – 55. A banana – 54.

Whole wheat wins!

Or loses…
