Dr. Weeks’ Comment: Strike the root by remedying the inflammation. Stop Dairy. It is not good for you
“... Men who reported the highest daily consumption of whole-fat milk had a 74% increased odds of high-aggressive prostate cancer compared with non-whole-fat milk drinkers…”

Background: Calcium and dairy product intakes have been positively associated with prostate cancer risk. An imbalance in concentrations of calcium and magnesium has been associated with multiple chronic diseases, although few studies have examined the relation with prostate cancer aggressiveness. Objective: The goal of this study was to examine the association between dietary intakes of calcium and magnesium, the calcium-to-magnesium ratio (Ca:Mg), and dairy products and prostate cancer aggressiveness. Design: Dietary intake was assessed with the use of an interviewer-administered modified National Cancer Institute Diet History Questionnaire in 996 African American and 1064 European American men with a recent histologically confirmed diagnosis of prostate cancer from the North Carolina-Louisiana Prostate Cancer Project (PCaP). High-aggressive disease was defined as Gleason sum ≥8, or prostate-specific antigen (PSA) >20 ng/mL, or Gleason score ≥7 and clinical stage T3-T4. The comparison group was all other prostate cancer cases. Logistic regression was used to determine the adjusted ORs and 95% CIs for high-aggressive prostate cancer by tertile of diet and supplement exposures.
Results: There was a positive association across tertiles of dietary Ca:Mg intake, with odds of high-aggressive prostate cancer in the upper tertiles as follows-OR for tertile 2 compared with tertile 1: 1.38 (95% CI: 1.01, 1.88); OR for tertile 3 compared with tertile 1: 1.46 (95% CI: 1.06, 2.02). When stratified by race, the positive association was more pronounced in African American men (OR for tertile 3 compared with tertile 2: 1.62; 95% CI: 1.04, 2.53). Men who reported the highest daily consumption of whole-fat milk had a 74% increased odds of high-aggressive prostate cancer compared with non-whole-fat milk drinkers, which was attenuated after adjustment for potential mediating factors, such as saturated fat and Ca:Mg intake. Conclusions: Among both African American and European American men diagnosed with prostate cancer, a higher Ca:Mg and whole-milk intake were associated with higher odds of high-aggressive prostate cancer.

Inflammatory potential of diet and risk of pancreatic cancer in he Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial: DII and pancreatic cancer risk in the PLCO study
Article International Journal of Cancer 142(12) · January 2018
Inflammation plays a central role in pancreatic cancer etiology and can be modulated by diet.
We aimed to examine the association between the inflammatory potential of diet, assessed with the Dietary Inflammatory Index (DII®), and pancreatic cancer risk in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial prospective cohort. Our study included 101,449 participants aged 52 to 78 years at baseline who completed both baseline questionnaire and a diet history questionnaire.
Energy-adjusted DII (E-DII) scores were computed based on food and supplement intake. Cox proportional hazards models and time dependent Cox models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) with participants in the lowest E-DII quintile (most anti-inflammatory scores) as referent.
After a median 8.5 years of follow-up, 328 pancreatic cancer cases were identified. E-DII scores were not associated with pancreatic cancer risk in the multivariable model (HRQ5vsQ1 =0.94; 95% CI=0.66-1.35; P-trend=0.43). Time significantly modified the association (P-interaction=0.01). During follow up <4 years, there was suggestive evidence of an inverse association between E-DII and pancreatic cancer (HRQ5vsQ1=0.60; 95% CI=0.35-1.02; P-trend=0.20) while there was a significant positive trend in the follow up ≥4 years (HRQ5vsQ1 =1.31; 95% CI=0.83-2.08; P-trend=0.03). Similar results were observed for E-DII from food only. Our study does not support an association between inflammatory potential of diet and pancreatic cancer risk; however, heterogeneous results were obtained with different follow-up times. These divergent associations may result from the influences of undetected disease in the short-term.
