    How many people were in the study? What co-existing disease/s and what stage/other treatment concurrently? Gender, ethnicity, age- i.e. What were the variables and how can we assess the validity of the information? Why powder and not real grapes? How often did the participants take the powder? Once a day, three times? In water or on food?
    Not enough information to consider this valid advice to anyone!
