Carrot (boiled): GI, GL, Carbs & Blood Sugar Impact

Glycemic index of carrots (39 cooked, ~16 raw), glycemic load, carbs per serving, and why the 'carrots are high sugar' myth is wrong.

39 Glycemic Index Low

4.7 g Fiber per 1 cup sliced, boiled (156 g)

Do Carrots Raise Blood Sugar?

Despite the old myth, carrots are not a sugar bomb. A cup of cooked carrot slices has about 13 g of carbohydrate and a published GI around 39 (raw carrots test much lower, near 16). The GL of a normal serving is very low.

How to Eat It

Raw or cooked, carrots are a safe, fiber-carrying vegetable for most people. The GI of other root vegetables is a separate story — see the potato page.

Estimated Glycemic Load

GL ≈ 3.2 per 1 cup sliced, boiled (156 g).

Calculation: GI (39) × available carbohydrate per serving (8.1 g = 8.2 g − 3 g fiber) ÷ 100. Calculated by DMSafeHaven; formula per standard published GL methodology.

Diabetes consideration: Despite the old myth, carrots are not 'high sugar' - a normal serving has a very low GL.
What can change the impact?
  • Raw vs. cooked
  • Portion size

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.
