Coconut Glycemic Index

Coconut flesh has a low glycemic index of about 35–45, depending on the source and preparation. The GI is low because coconut is high in fiber and fat and low in net carbohydrates. Coconut water has a higher GI (50–55) due to its natural sugar content. This is general nutrition information — individual responses may vary.

Coconut flesh is a diabetes-friendly food in typical portions. It is low in net carbs, high in fiber, and contains healthy fats that help stabilize blood sugar. Coconut water, however, contains more sugar and should be consumed in moderation. People with diabetes should discuss portion sizes with their care team — this is not medical advice.

Coconut flesh has minimal effect on blood sugar due to its low net carb content and high fiber and fat. A one-cup serving of shredded coconut contains only about 5 g of net carbs. Coconut water can raise blood sugar moderately because it contains natural sugars. The GI of coconut flesh is low (35–45), meaning it causes a slow, small rise in blood glucose.

Coconut water can be consumed by people with diabetes in moderation. One cup (240 ml) contains about 6 g of sugar and has a moderate GI of 50–55. It is lower in sugar than most fruit juices but higher than plain water. People with diabetes should limit portions to one cup and consider it part of their daily carbohydrate intake.

Coconut is botanically a fruit (drupe) but is often grouped with nuts and seeds for nutritional purposes. It is lower in net carbs than most nuts (almonds, walnuts) and higher in saturated fat. Its GI (35–45) is similar to that of almonds (GI ~15) and walnuts (GI ~15), all of which are low. Coconut's high fiber content makes it particularly blood-sugar-friendly.

Yes, coconut is a staple of keto diets because it is low in net carbs and high in healthy fats. One cup of shredded coconut has about 5 g of net carbs and 27 g of fat, making it ideal for maintaining ketosis. Coconut oil and coconut milk are also keto-friendly. Coconut water is not keto-friendly due to its sugar content.

Glycemic load accounts for both the glycemic index and the actual carbohydrate amount in a serving, giving a more realistic picture of blood sugar impact. Coconut flesh has a glycemic load of roughly 2 to 4 per typical serving, considered low, because even though its GI is moderate (35-45), a serving contains very few net carbs (about 5 g per cup). Coconut water has a higher glycemic load (around 3 to 6 per cup) due to its natural sugar content, though it remains in the low-to-moderate range. This is general nutrition information; individual responses vary.

Coconut oil has no meaningful glycemic index because it contains virtually no carbohydrates — it's pure fat. The glycemic index measures blood sugar response to carbohydrate-containing foods, and pure fats like coconut oil don't raise blood glucose directly. This makes coconut oil carbohydrate-neutral for blood sugar purposes, though it's calorie-dense and should still be used in moderation as part of an overall diet, especially for anyone managing weight or diabetes.

Canned coconut milk, used in cooking, has a low glycemic index similar to coconut flesh (roughly 35-45) because it's high in fat and low in carbohydrates. A typical serving contains only a few grams of net carbs, so both its GI and glycemic load are low. This differs from coconut water, which has a higher GI (50-55) due to its natural sugar content. Always check whether a recipe uses canned coconut milk or coconut water, since their blood sugar impact differs.

Processing coconut — whether dried, shredded, or in flakes — doesn't meaningfully change its glycemic index, since the fiber and fat content that keep the GI low stay largely intact. Dried, unsweetened shredded coconut remains in the same low GI range (roughly 35-45) as fresh coconut flesh. The main caveat is added sugar: some packaged shredded or flaked coconut products include added sugar, which does raise the glycemic load, so check the label for 'unsweetened' versions to keep the GI low.
