This study explored the use of protein meals with ginger (not specified) for the treatment of delayed nausea from chemotherapy. Twenty-eight patients with cancer receiving chemotherapy for the first time were assigned to one of three groups. For 3 days, beginning the day after their chemotherapy, control group patients continued with their normal diet, protein group patients consumed a protein drink and ginger twice daily, and high-protein group patients consumed a protein drink with additional protein and ginger twice daily. Patients recorded in a diary each day whether they had experienced nausea, whether their nausea had been frequent, whether their nausea had been bothersome, and whether they had needed any antiemetic medication. Gastric myoelectrical activity was assessed in five patients before and after ingestion of a high-protein meal and ginger. Reports of nausea, frequent nausea, and bothersome nausea were significantly less common among high-protein group patients than among control and protein group patients. Furthermore, significantly fewer patients in the high-protein group used antiemetic medication. Differences between the protein and control groups were not statistically significant. In the five patients who had tests of gastric myoelectrical activity performed, a significant decrease in gastric dysrhythmia occurred after ingestion of the protein and ginger.
