Foods, nutrients and prostate cancer: a case–control study in Uruguay

A case-control study of diet and prostate cancer was conducted in Montevideo, Uruguay involving 175 cases and 233 controls. When the highest quartile of intake was compared with the lowest, positive findings were obtained for red meat intake (OR 2.0, 95% CI 1.1-3.8), desserts (OR 1.8, 95% CI 0.9-3.3), total energy (OR 1.9, 95% CI 1.0-3.4) and total fat intake (OR 1.8, 95% CI 0.9-3.4). On the other hand, vegetables and fruits (OR 0.5, 95% CI 0.3-0.9), vitamin C (OR 0.4, 95% 0.2-0.8) and vitamin E (OR 0.6, 95% CI 0.3-1.1) were associated with reduced risks of prostate cancer. Possible mechanisms are discussed.
