As per the expectations of the Canadian Cancer Society, the graph of prostate cancer would continue to rise, and more than 23,000 people would have it by 2020.
A large number of studies target diet as the major risk factor among others for the growth of prostate cancer. Several health conditions like obesity, cardiovascular diseases, and diabetes center point also lie in a poor diet plan.
Analyzing Three Types of Diet against Prostate Cancer
A research team of Professor Marie-Élise Parent of Institut national de la recherche scientifique (INRS), analyzed the study from 2005 to 2012 taken in Montreal to prove the link between diet and prognosis of prostate cancer.
His study, “Dietary Patterns Are Associated with Risk of Prostate Cancer in a Population-Based Case-Control Study in Montreal, Canada,” became public in June in the journal Nutrients.
Karine Trudeau, the lead author, and INRS Ph.D. student, evaluated the results on a salty Standard American Diet (SAD) with alcohol, a healthy diet, and a high sugar content American Diet with beverages – three major categories of nutrient profiling.
The first profile includes a major portion of meat and beverages like beer or wine. The healthy diet mainly comprises of vegetables, fruits, nuts, tofu, and other plant proteins. The last profile is all about unhealthy carbohydrate-rich food like pizza, pasta, sweet dish, and carbonated drinks.
To get fair results, the researchers took records of race, family history, education, the last ultrasound scan for prostate cancer, and age. Marie-Élise Parent and Karine Trudeau found that healthy eating has the potency to reduce the chances of prostate cancer.
Meanwhile, the third nutrient profile was linked to an increased risk of prostate cancer. Also, it was found to trigger other aggressive forms of cancer. Surprisingly, the first dietary profile did not have any clear connection with the development of prostate cancer.
Focus on One Nutrient or the Whole Diet – What is better?
Other than the participation of INRS faculty and students Marie-Élise Parent, Ilona Csizmadi (Cumming School of Medicine), Karine Trudeau, Christine Barul, and Marie-Claude Rousseau took part in the prostate cancer research.
Researchers did not opt for a typical approach to study the link and focused on only one group or nutrient. Instead, this time they studied dietary profiles on a broader scale.
Ms. Trudeau highlights how difficult it is to solely isolate and focus on the effects of one dietary nutrient. For example, vitamin C in citrus fruits works best for increasing iron absorption. Also, dairy products rich in vitamin D have a high content of calcium for stronger bones.

It would help produce results that are more meaningful and could be used by the public health sector for recommendations. The researchers point out that people should consider an allover diet for their health rather than only one nutrient.
Professor Parent says that even though, they knew that diet plays a critical role in the progress of prostate cancer. It was hard for them to identify specific factors. The study holds immense importance in the field of control and prevention of diseases as it looks at diet on the whole.
This study might open new windows to control diseases. Most importantly, they have found evidence that might help in planning strategies to keep prostate cancer at bay. Not to forget, prostate cancer is the most widely spread form of cancer in Canada and many countries.
The Canadian Cancer Society (CCS), , Fonds de la recherche du Québec—Santé (FRQS), Ministère de l’Économie et de l’Innovation (MEI), and the Cancer Research Society (CRS) took part by sending large funds for the progress of the study.
