Does Peach Raise Blood Sugar?

A medium peach has only about 14 g of carbohydrate and a published GI around 42. Fresh peaches are gentle on blood glucose; the canned-in-syrup version is a different food entirely.

How to Eat It

Fresh and plain, or with a little yogurt. If buying canned, choose no-added-sugar versions.

Estimated Glycemic Load

GL ≈ 5.0 per 1 medium peach (150 g).

Calculation: GI (42) × available carbohydrate per serving (12.0 g = 9.5 g − 1.5 g fiber) ÷ 100. Calculated by DMSafeHaven; formula per standard published GL methodology.

Diabetes consideration: Fresh peaches are low in carbohydrate and generally gentle on blood glucose.
What can change the impact?
  • Fresh vs. canned in syrup
  • Ripeness

GI values can vary with variety, ripeness, preparation and testing conditions. The value above is a typical published figure, not a universal prediction for every individual or every serving.
