Answer: Cactus pears fit the keto diet in moderation.
Each serving of cactus pears (1 cup) contains 8.9 g of net carbs. That's on the high side, but you can still squeeze in small amounts if you've got a strong craving for this tasty fruit.
Consider limiting yourself to half a portion per day to avoid going over your carb limits.
Cactus pears contain 23% of your daily value of vitamin C, an essential antioxidant that can help prevent cardiovascular disease.
