High Carb, High Fiber, No Dairy: All Linked To Lower Prostate Cancer Risk

ProstateGraphic2Here are three abstracts from this year’s American Urological Association meeting. All of them provide evidence for eating a whole food, plant-based diet to reduce the risk for prostate cancer.

(To read the abstract, visit the  abstract search page and enter the PD number in the “Publication Number” field.)

1. Carbohydrate Intake, Glycemic Index, And Prostate Cancer Risk, Abstract PD31-11.

This study analyzed data from 430 veterans’ medical records. Those eating the most carbohydrate had up to a 75% lower risk for prostate cancer compared with those eating the least. High fiber intake was also associated with a significant reduction in prostate cancer. Interestingly, these researchers conducted this study because they thought that a high-carbohydrate diet was a risk factor for prostate cancer. They found the opposite.

“Conclusions: Among men consuming a Western diet, our findings suggest higher carbohydrate intake and thereby lower intake of other macronutrients (i.e. protein and fat) may be associated with reduced risk of overall [prostate cancer] and both low- and high-grade [prostate cancer]. … When examining the [glycemic index] of the diet, there was no association.”

2. Dairy Intake And Prostate Cancer Risk: Results From The California Collaborative Prostate Cancer Study, Abstract PD31-06

Data from 2953 cases and controls were analyzed. From MedPageToday: “Compared with men who reported rarely or never drinking milk, low intake was associated with a 33% increase in the odds of advanced prostate cancer, increasing to 43% among men reporting high intake (P=0.037 for trend).”

“Conclusions: These finding suggest that even though most of the putative effect of dairy products on [prostate cancer] risk seems to be explained by calcium, among men with overall low levels of calcium from diet and supplements, high intake of dairy products seems to have a separate effect, suggesting additional components in dairy that may contribute to prostate cancer development.”

3. Metabolic Syndrome Components And Prostate Cancer Risk: Results From The REDUCE Study, Abstract PD31-01

This study analyzed data from 6,426 men who took part in the REDUCE trial (Avodart/dutasteride vs. placebo, Avodart is used for BPH). Men with two components of the Metabolic Syndrome had a 35% increased risk for prostate cancer; men with 3 or more components had a 94% increased risk.

Metabolic Syndrome consists of these 5 components. Having 3 or more means you likely have Metabolic Syndrome, and now, apparently, a higher risk for prostate cancer:

  • Abdominal obesity (high waist circumference)
  • Elevated blood pressure
  • Elevated triglycerides
  • Low HDL cholesterol
  • Elevated fasting glucose

“Conclusions: Men with multiple [Metabolic Syndrome] components may be at higher risk of being diagnosed specifically with high-grade [prostate cancer].”

If the claims made by low-carb enthusiasts are true … that eating a low-carbohydrate, high-fat, high-protein, high animal food diet lowers the risk for cancer, why do so many studies point to the opposite?
