The skin of dragon fruit contains very valuable nutrients - anthocyanins, which is a powerful antioxidant and immune-boosting substances, can be preserved in the human bloodstream for 75 hours of activity, more than 10 times the antioxidant capacity of carotene. Through the bloodstream, it is transported throughout the body to play the role of antioxidant, anti-free radical, anti-aging, and inhibit Alzheimer's disease.

When eating dragon fruit, you can use a knife to scrape off the inner purple peel - they can be eaten raw, cold, or juiced with a little sugar and refrigerated for better flavor. The peel should not be eaten in tea, soup or steamed, high temperatures can lead to partial degradation of anthocyanins, thus reducing their nutritional value.
