To far oversimplify the question, yes, fruit is primarily a carbohydrate-rich food group. But that isn't a bad thing.
They also contain fiber, which is technically a carbohydrate, and one that offers numerous health benefits including satiety (keepin' you full), powerful risk-reduction of many chronic diseases like heart disease.
So while fruit may be rich in carbs, it's also rich in nutrients, and shouldn't be avoided.
On the lower-carb end, there are fruits like strawberries, raspberries, blueberries, blackberries, watermelon, pineapple, papayas, coconut, honeydew, cantaloupe, lemon and avocado (which yes, is technically a fruit).
