Whether red-hearted or white-hearted, there are three key points to picking a dragon fruit:
1. Look at the appearance. A sweet and delicious dragon fruit should have a vibrant color, a smooth skin, and no signs of rot. Typically, rounder ones are red dragon fruits, while more oval-shaped ones are white dragon fruits. Red dragon fruits generally have a better texture, higher anthocyanin content, and stronger antioxidant, free radical-scavenging, and anti-aging effects.
2. Look at the color. When choosing a dragon fruit, the redder the skin, the better, as this indicates its ripeness.
3. Feel the weight. The heavier the dragon fruit, the more juice and fleshier it is. Therefore, when buying, you should weigh it in your hand—the heavier, the better.
