Like lemons, limes are a great way to boost the flavor of a dish for very little carbohydrate.

Carbohydrate and Fiber Counts for Limes

Since we usually don't eat limes, but instead use the juice, I have provided information on fresh lime juice.

• 1 Tablespoon fresh lime juice: 1 gram effective (net) carbohydrate plus 0 grams fiber and 4 calories.
• Juice of 1 medium lime (a little over 1.5 oz): 4 grams effective (net) carbohydrate plus 0 grams fiber and 11 calories.

Glycemic Index for Limes

There is no scientific study of the glycemic index of lime juice, probably because it is usually consumed in such small amounts.

Health Benefits of Limes

To get a significant amount of nutrients from lime juice, you'd have to use more juice than usual. Still, ¼ cup of lime juice is a very good source of vitamin C, and there are a number of healthful phytonutrients in limes as well.
