Dragon what? When I gave my classmates dragon fruit to eat one time, they were very confused by how it tasted. Then again, when most people first encounter dragon fruit they don't really know how to eat it, let alone what it tastes like. Most people have the expectation that since the fruit looks good, its taste is going to pack a punch which isn't always the case. The dragon fruit has a stunning fuchsia pink exterior, and in my opinion, it has a sweet taste just like longan. The dragon fruit has little carbohydrates and is rich in antioxidants like Vitamin C and B's. This helps boost the immune system and since the fruit has little carbohydrates, it makes it easier for digestion.
Similar to the longan, dragon fruit has a high content of fructose which means that it's unhealthy to consume this fruit in mass amounts, especially if you're diabetic
