Diet plays a role in modifying cancer risk. This study from Ericsson and colleagues provides new evidence suggesting that avocado intake could aid in cancer prevention. However, these effects were observed only in men, pointing to intriguing key differences by sex. Also, associations were only seen for some (colorectal, lung, and bladder cancers), but not all cancer types. Still, the number of avocado servings and ways to eat avocado to obtain these benefits remain to be determined. This brief commentary discusses the study and provides an opinion on the proposed role of avocados in reducing cancer risk. See related article by Ericsson et al., p. 211.
