Dairy and prostate cancer: Conflicting information

Posted by rice @rice, Apr 18, 2024

Hi! I am 73 and have 6 prostate cancer that is being watched. I drink a lot of milk and eat a lot of cheese I have read some studies that say whole milk was associated with prostate cancer and to drink fat free milk. Then I read another study saying that skim milk was associated with prostate cancer, but high fat milk was ok to drink. Then I read another study that says no association between dairy and Prostate cancer. Kind of confusing ! does anyone have an opinion on this

Interested in more discussions like this? Go to the Prostate Cancer Support Group.

Hey Jacko, are you sure that’s Ripple MILK and not Ripple WINE? 😁
Remember that stuff?
Your diet sounds like a sane, well balanced one so stay on it. What always gets me when “experts” say to avoid dairy is that milk - good organic milk - contains estrogens!
So they tell you that milk may cause or enhance the chance of PCa but then they put you ON ADT when you get PCa!! Do you see a totally f****d up mixed message here?
Don’t eat dairy - it contains estrogen hormones!! You have prostate cancer - we’re putting you on estrogen-like hormones!!
Maybe a better treatment should consist of 35% heavy cream since it contains the highest amount of estrogen/progesterone and would be a great and tasty substitute for ADT?
My suggestion is, of course, absurd; but so are the many boilerplate dictums handed out like candy by these “experts”.
Maybe estrogen sensitive breast cancer might be affected by dairy for obvious reasons, but much more actual research needs to be done for PCa.

Back in my day it was Boone’s Farm Apple wine and
Mogen David. I recently read some other prostate related suggestions. First, a study was done that showed white mushroom supplements had an effect on slowing PC. Second, some food suggestions to reduce glucose: berries, Greek Yogurt(doesn’t it have dairy?) and dark chocolate. I gave up chocolate but recently found a plant based dark chocolate called JoJo’s. It has cashews, almonds and cranberries in small chocolate squares. It was created by a mother who had cancer and was looking for an alternative to satisfy her sweet tooth. I bought some at Costco. Low carbs, very little sugar and pretty good taste. No doubt we all have our dietary beliefs. Hope all is well. PS. Stay off of that Wine!

Aren't all chocolates plant based? Chocolate comes from the cacao tree after all.

Note that some of these are studies and some are lit reviews (skimming other studies), and none does more than identify a correlation.

It could turn out that one or more of these foods has a direct causal effect on prostate cancer, but that would be a long way off. It could also turn out (and probably will, in most cases) that the kind of men who eat a lot of meat, eggs, etc are the kind of men who are more likely to get advanced prostate cancer because of some shared unknown factor, which wouldn't go away if they stopped eating them. In Dr Walsh's book, the one food that seemed to be accumulating enough evidence for a definite go-light recommendation was processed meats (bologna, hot dogs, etc). Again, not never, but go really easy them.

FWIW, I've been vegetarian since 1997, and was still diagnosed with de-novo stage 4 prostate cancer in 2021. Using moderation with high-cholesterol foods like meat, eggs, and full-fat dairy is a good health choice regardless, and we do know that obesity appears to have a strong correlation with many cancers, but I don't think we can control our own cancer destinies by cherry-picking isolated studies and lit reviews and chasing them. Our best bet is to eat a healthy balanced diet, stay active, and stick to our treatment (getting second and third opinions when necessary).

Well yeah, I have been at many meeting where correlations are used and some correlations are really strong when data is mapped out and statisticians come in. What do you want somebody to hit you on the head, just kidding of course but I don't think what we are looking at is cherry picking either. Obviously we should do whatever we want, and that is the way medicine should go, patient decides path, but sometimes correlations help (and not just fire engines at fires). I chose Tulsa Pro 1.5 years ago, but no docs are advising Tulsa just yet till something hits them in the head and gives them the machines and training. Things take time on all these things, but we make our own paths. I have really bad inherited cholesterol, so maybe I inherit one source of the problems that contribute, yet eating plant food since start of the year and I have the best cholesterol in 30 years+. So maybe things help and correlations are pretty good too. Maybe you inherit a whole bunch of other things and it isn't related to fats or foods for you but some other gene, or radon gas you were exposed to as a kid, or who knows? I don't, we just work with data as we see for ourselves.

Chocolate is plant-based, but many cheaper "chocolate" products contain more dairy products (like whey powder) than actual cocoa.

Many have milk fat or butter in them. Nestles milk chocolate chips have both butter and milk fat, for example.

Hey BJ, are you on a statin? I know several people who had zero success with plant based diet. When they finally relented, the statin brought their numbers down dramatically.

Not on statin and cholesterol now great. I did statin last year and tried all kinds of things doctors advised for decades, to be honest it didn't help with any of them (including advised exercise) on cholesterol, or at least not much. Maybe statins are better than nothing but not by much for me. Those high dose niacin pills that make you flush did work somewhat for me, and did that for a long time till it became unpopular amongst doctors who now advise against that route. I am sure I could go back to statin but it doesn't really do anything for me. Plant based diet did real good job on my cholesterol, only thing that I tried ever that worked on cholesterol. In the game changers movie you see it had that effect on others in the movie, as well as other things. Hoping it does more for me, but it sure does a job on cholesterol.
