grape juiceA double-blind, placebo-controlled study, published in Oncology Nursing Forum (2010; 37(2): 213-21); it looked at the effect consuming grape juice had on nausea and vomiting in chemotherapy patients. The subjects were 77 cancer patients undergoing chemotherapy who were randomly assigned to receive either a placebo or 4 oz. of grape juice prior to meals following each of four chemotherapy cycle. The subjects receiving the grape juice vomited less frequently and experienced less nausea and distress than the subjects in the placebo group.
