You can eat watermelon during chicken pox, and it is recommended that you eat more green leafy vegetables and fruits during chicken pox to replenish the vitamins your body needs, and also pay attention to water replenishment. The actual fact is that you will not be able to eat spicy food, such as onion, ginger, garlic, chili, mustard; avoid eating greasy food and hairy items, such as mutton, dog meat, fish, shrimp, crab, etc. These hairy items tend to aggravate the symptoms of chicken pox.
