Answer: Cranberries fit the keto diet in moderation.
Each serving of cranberries (1 cup, chopped) contains 9.2 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.
Though fresh cranberries fit the keto diet, canned or dried cranberries do not. Packaged cranberries contain tons of added sugar that manufacturers use as a preservative.
Cranberries contain 17% of your daily value of vitamin C, an essential antioxidant that can help prevent cardiovascular disease.
