We have previously found a positive association between milk consumption and prostate cancer risk using meta-analysis to analyze published case-control studies. In the present study, further meta-analysis was conducted to estimate the summary relative risk (RR) between the consumption of milk and dairy products and prostate cancer from cohort studies published between 1966- 2006. We found 18 relevant articles and 13 independent studies were available for our analysis. The summary RR was 1.13 (95% confidence interval = 1.02-1.24) when comparing the highest with the lowest quantile of consumption. The summary RRs by study stratification showed a positive association. A dose-response relationship was identified when combining the studies that partitioned the consumption by quintiles. We also evaluated the effects of some limitations, such as dairy classification, prostate cancer stages and publication bias, in the present study. These findings, together with the previous study, suggest that the consumption of milk and dairy products increases the risk of prostate cancer. This is biologically plausible since milk contains considerable amounts of fat, hormones, and calcium that are associated with prostate cancer risk.
then...milk kefir is dangerous for men too?
Not likely for two reasons. Kefir is generally made with organic milk, which would have considerably less estrogen to begin with. Secondly, the bacteria in kefir are well known for breaking down estrogen metabolites, so they are likely to break down actual estrogens in the process of fermentation.
Yes, eggs also contain hormones. But again, they can be consumed in limited quantities.
Is it alright for a cancer patient to eat two eggs a day or is that too much? What is your recommendation for egg consumption?
A couple of eggs a day is not a problem. Especially if the diet contains a lot of plants since the plants contain phytoestrogens that antagonize estrogens.
