To the Editor In their study of the effect of resveratrol on mortality, Semba and colleagues1 found that the alcohol intake of those who were alive after the 9-year study was only slightly higher (and not statistically significant) than the alcohol intake of those who died during the 9 years of the study. Similarly, the total urinary resveratrol metabolites were not significantly higher in the group who were alive.
