Disease analysis: People with low white blood cells after chemotherapy should also eat more foods rich in vitamins in their daily lives, such as various fresh vegetables and fruits. This vitamin-rich food can not only help patients effectively enhance their immunity, but also increase their appetite. Suggestion: Although patients after chemotherapy should eat less cold food, fruits and vegetables should be treated as appropriate. Especially in the early stage of chemotherapy, patients should eat more vegetable juice and a small amount of digestible fruit, and pay attention to a small amount of meals.
