Why not? Pitaya is extremely low in calories and rich in plant protein. Fruit and vegetable fiber is also full, which can increase gastric motility. The only bad thing is that pitaya has the word fire. Actually, it is really cool fruit. Therefore, people with bad stomachs should eat less, or they will have diarrhea once. Although the detoxification effect is good, it will not be cool to run the toilet six or seven times a day. In addition, pitaya has a high vitamin content, which is very suitable for supplementing vitamin C lacking after fitness. I usually drink protein powder and a glass of dragon juice for half an hour after fitness. But pitaya is too expensive to eat. One in the north is nearly ten yuan. So I only buy it occasionally when the rotten skin is on sale. It's not bad to eat an apple after fitness. In short, eat a fruit after fitness. Pitaya tastes better.
