Nectarines and the Glycemic Index

The glycemic index ranks food on a scale of 0 to 100. How high and how quickly a particular food raises blood sugar levels determines where a food falls on the scale. The lower the ranking, the less impact the food has on blood sugar and insulin fluctuations. Following a diet that emphasizes lower glycemic-index foods can help diabetics control glucose levels and reduce insulin resistance, according to the University of Sydney. Lower glycemic-index foods can also be beneficial for weight loss.

Nectarines' Glycemic Ranking

Raw nectarines have a glycemic index rank of 43, according to the University of Sydney's website. The ranking is based on a serving of 120 grams, or approximately 4 ounces. Nectarines are low glycemic-index foods because, according to Self Magazine, any food with a glycemic index of 55 or below is considered low. Any ranking above 70 is high and will cause blood sugar levels to rise rapidly.
