Abstract: Dietary intake has been implicated as one of the factors associated with prostate cancer. This study is aimed at assessing the role of high fat diet as a risk factor for prostate cancer. Articles were reviewed which included case control studies, cohort studies or randomized clinical controlled trials published between 1997 and 2017 that focused on the role of high fat diet as a risk factor for prostate cancer in humans. Ten (10) articles were then selected based on the relevance to the research topic and most recent of the articles. Out of the ten articles selected and reviewed, four were prospective cohort studies with sample sizes ranging from 525 to 10,564 participants, while six were case control studies with sample size ranging from 90 to 932 participants.
