Healthy diet protects against prostate cancer

The Canadian Cancer Society estimates that more than 23,000 Canadians will be diagnosed with prostate cancer in 2020. Among other risk factors, more and more studies point to diet as a major factor in the development of prostate cancer, as it is for cardiovascular disease, diabetes, and obesity.

Using data from a study conducted in Montreal between 2005 and 2012, a research team has shown a connection between diet and prostate cancer.

Three dietary profiles analyzed

The analysis was based on three main dietary profiles: healthy diet, a salty Western diet including alcohol, and a sugar-rich Western diet with beverages.

The first diet profile leans heavily towards fruits, vegetables and plant proteins like tofu and nuts. The salty Western diet with alcohol includes more meat and beverages such as beer and wine. The third profile is rich in pasta, pizza, desserts, and sugary carbonated drinks.

The study took age, ethnicity, education, family history, and date of last prostate cancer screening into account.

The researchers found a link between a healthy diet and a lower risk of prostate cancer. Conversely, a Western diet with sweets and beverages was associated with a higher risk and seemed to be a factor in more aggressive forms of cancer. The study did not show any clear link between a Western diet with salt and alcohol and the risk of developing the disease. 

For a long time researchers have suspected that diet plays a role in the development of prostate cancer, but it was difficult to pinpoint the specific factors involved. This study is significant because it looks at dietary habits as a whole, rather than single foods or nutrients.

However, it was not a randomized controlled trial and therefor does not prove that a healthy diet lowers the risk of developing prostate cancer; it found an association only.
