The Science Supports a Mostly Plant-Based Diet for Prostate Cancer

systemic-review study shows a plant-based diet’s protective benefits for prostate cancer.

What’s the difference between a Systemic Review and a Meta-Analysis

You have heard me highlight meta-analysis and systemic review studies in the past. The difference between the two is the following:

  • A systemic review is an overview of most, if not all of the studies in a given topic using research methods to limit biases and find clinical significance.
  • A meta-analysis uses a statistical strategy for finding the results of several studies into one single conclusion.

In some cases, a study can be both a systemic review and meta-analysis. I love to collect information from these two methods of studies as it guides clinical therapies that may be most effective.

Medicine is an art as much as a science.

Here’s a summary of this newly published systemic review study:

  • Two highlighted lifestyle studies showed protective benefits from a lifestyle approach, including Exercise, stress management, some dietary supplements, and a plant-based diet. 
      • Dietary supplements included fish oil, vitamin E, selenium, and vitamin C
      • I think the magic is in all components of lifestyle, not only diet.
  • Another study showed increased PSA doubling time in subjects with increased consumption of plant-based foods and oily fish, reducing or eliminating land-animal-based protein (including dairy), and mindfulness training. 
      • Here, fish seems to be beneficial, which is a food I recommend.
  • Yet another study in men with biochemical recurrence after treatment for prostate cancer showed a slower rise or overall reductions in PSA levels in men who underwent a plant-based diet and stress-reduction intervention over six months. 
      • Men with more waist size reduction corresponded temporally with the PSA decreasing.
  • In Germany, vegetarians had a nearly 60% lower mortality due to prostate cancer, although it was not statistically significant.
      • In nine patients with metastatic prostate cancer who adopted a modified plant-based diet to varying degrees in addition to conventional, three patients in the plant-based diet group experienced long-term improvement or regression of bone lesions compared to no patients in the control group.

Here’s a simple way to look at diet for prostate cancer:

  • Eat real food. Mostly plants. Not too much – Michael Pollan 
  • Practice Intermittent fasting. 
      • The bigger problem is that people overeat too often, which might be a significant cancer promoter.
  • Eat organic when possible.
  • Stay away from non-organic fruits and vegetables most contaminated with carcinogenic chemicals, dirty dozen.
  • Never eat with guilt.
