A 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.
