Study: “Western Diet” High In Meat, Dairy, Refined Grains Increases Risk For Death From Prostate Cancer

WesternDiet2I just posted about a study which found that a higher intake of dairy foods increased death from prostate cancer for men who had been diagnosed. Here’s a study by the same group of authors, using the same cohort: 926 men from the Physicians’ Health Study.

Dietary Patterns after Prostate Cancer Diagnosis in Relation to Disease-Specific and Total Mortality, Cancer Prevention Research, June 2015

In this study, men who had been diagnosed with prostate cancer were 2.5 times more likely to die from it if they ate a “Western Diet” compared to a “Prudent Diet”:

Two post-diagnostic dietary patterns were identified:
– A Prudent pattern, characterized by higher intake of vegetables, fruits, fish, legumes, and whole grains.
– A Western pattern, characterized by higher intake of processed and red meats, high-fat dairy and refined grains.

Those eating the Western Diet also had a 67% increased risk for death from causes other than prostate cancer.

Conclusion: A post-diagnostic Western dietary pattern was associated with higher prostate cancer–specific and all-cause mortality, whereas a Prudent dietary pattern was related to lower all-cause mortality after prostate cancer diagnosis.

I just saw a quote by Dr. Greger on these findings:

“The results of this study are consistent with previous findings showing eggs and poultry consumption is associated with two to four times the risk of prostate cancer progression and linking dairy consumption to the development of prostate cancer in the first place. In contrast, a whole-food, plant-based diet and other healthy lifestyle changes have been shown to reverse the progression of prostate cancer in men with early stage disease.”

    A thought … these men with prostate cancer are all physicians. You would think they know what to eat, to reduce their risk of progression. You would think they know the science, have read the studies. No? Yes?

    What do they tell their patients with prostate cancer?
