Background: Prostate cancer (PCa) in men is, to date, the number one cause of death from cancer worldwide. PCa has been associated with a large number of lifestyle factors, including unhealthy dietary habits. In particular, diet and nutrition have been shown to play pivotal roles in PCa, and the habitual consumption of certain specific foods like meat cooked at very high temperatures has been implicated. However, this has not been documented among Black men. The aim of this study was to determine the association between dietary patterns and their association with the occurrence of prostate cancer. Method: This is a longitudinal multisite Prostate Cancer Transatlantic Consortium (CaPTC) familial cohort phase 2 study. Participants were Nigerian Black men between 35 and 70 years old who were willing to participate in the study over a 10-year period. For the food variety score, a score of 1 was given for each food item eaten weekly, and the aggregate food variety score was totaled and categorized as ≥54% very good, 45%–53% was good, 36%–44% fair, 18%–35% poor and &lt;18% was very poor. Data were analyzed using descriptive statistics, such as frequency analyses. Chi-square analysis was used to evaluate dichotomous variables to compare groups based on demographic factors and the occurrence of PCa. Multivariate logistic regression was used to determine the specific predictors of the diagnosis of PCa with potential adjustment for the other demographic variables. P-values &lt; 0.05 was set as significant. Results: A total of 780 participants were recruited, with 72.6% reporting no history of cancer. The median age was 47.00 (range: 21-97),16.5% have been diagnosed with Pca, and 1.5% were diagnosed with other Cancers. Age of cancer diagnosis showed that 21% were diagnosed at about 50 years. Participants’ fruit consumption showed that 28.4%, 29%,  39.5%, 23%, 31%, 28.7%, and 39.2, ate apples, mango, citrus, papaya, green banana, tomatoes, and watermelon, weekly, respectively. Fish was the most consumed protein source of animal origin irrespective of the cooking methods categories, such as boiling, frying, grilling, and smoking. The median food variety score was 20 (0-67), with 8.5%, 3.8%,49.3%, and  26.8% classified as good, very good, poor, and very poor, respectively. Multivariate analysis showed that the category of food variety score (P=0.0009), age (P&lt;0.0001), and grilled fish consumption (P=0.0333) were found to be associated with Pca occurrence. Conclusions: The study showed that food variety score, age, and fish consumption were the correlates of prostate cancer occurrence in the population studied.
