New study associates intake of dairy milk with greater risk of prostate cancer

Men with higher intakes of dairy foods, especially milk, face a significantly higher risk of prostate cancer compared to men with lower intakes, according to a new study. The study found no such associations between increased prostate cancer risk and intake of non-dairy calcium, suggesting substances other than calcium play a role in the risk dairy foods poses for prostate cancer.

The study's results reveal that men who consumed about 430 grams of dairy per day (1 ¾ cups of milk) faced a 25% increased risk of prostate cancer compared to men who consumed only 20.2 grams of dairy per day (1/2 cup of milk per week). Also, men who consumed about 430 grams of dairy per day faced an even greater increase in risk when compared to men with zero dairy intake in their diets.

"Most of the continuing increase in risk is done with by the time you get to 150 grams, about two-thirds of a cup of milk per day," Fraser said. "It's almost as if some biological or biochemical pathway is saturated at about two-thirds of a cup of milk per day."

Fraser said the possible reasons for these associations between prostate cancer and dairy milk might be the sex hormone content of dairy milk. Up to 75% of lactating dairy cows are pregnant, and prostate cancer is a hormone-responsive cancer. Further, prior reports have associated intake of dairy and other animal proteins with higher blood levels of a hormone, insulin-like growth factor-1 (IGF-1), which is thought to promote certain cancers, including prostate.

A prior study from Adventist Health Study-2 about the effects of dairy on breast cancer risk in women reported similar results both in the non-uniform risk with increased consumption levels and in the magnitude of risk, Fraser said.

I can see how both the sex hormone and the IGF-1 could be problematic, but my wife and I like our milk products, so cutting these down will be difficult.

I am not a calf and don’t drink cow milk.

[BipolarBob]

Fair Life milk is a good choice if you like milk. Ultra purified. Tastes better and lasts longer.

[jimtorr]

I would investigate any links between the sponsors of this study and any anti-dairy products groups. Science seems to become more mercenary every year.

[ProtectOurFreedom]

I’d need to cut my milk consumption by 99.3%? Are they nuts?

Bull CRAP!!!!!!

Two things of note, one of which I failed to include in the excerpt:

“Fraser noted that the results had minimal variation when comparing intake of full fat versus reduced or nonfat milks; there were no important associations reported with cheese and yogurt.”

From another study:

Results: Each 400 g increment in daily dairy intake was associated with 16.8 µg/L (95% CI 6.9, 26.7) higher IGF-1 concentrations. Each 200 g increment in milk per day was associated with 10.0 µg/L (95% CI 4.2, 15.8) higher IGF-1. In contrast, we observed no association between cheese or yogurt intake and IGF-1 concentrations.

Cheese and yogurt created no IGF-1 problems in either study! Only normal milk products did.

Now, it's just left to the possible sex hormone issue.

I drink raw cow A2 and goat milk. Not worried about prostate cancer. Maybe industrial milk but I’ll keep guzzling raw

[LilFarmer]

Don’t worry, Gates and his BIOMILQ will replace all dairy. 😳

[ConservativeMind]

It was performed alongside an Adventists hospital, but do note the study agreed with another study I posted above that described cheese and yogurt as not affecting IGF-1 levels.

[Revel]

Recently there was a study that said that Cheese was really good for the heart. These people are all clowns.

I use lactose free milk. I’ve had Fairlife, and it’s good. I’ve been wanting to try oat milk, I’ll just have to spend the money for it. It’s all expensive, anymore.
I gotta have my milk😛!

[Mount Athos]

I’m willing to die earlier for milk products

[telescope115]

At almost 68 yrs, my pleasures are not as plentiful as they were when I was younger. If drinking milk is going to shorten my life span, I will drink it happily!
The way I see it, I have already cheated death two, if not three times. I probably wouldn’t be here now, if not for God looking out for me.
Bring on the milk!!

[Parmy]

You just can’t believe all of this. It is just another money grabbing scam to get grants and scare people who like to be scared.

[Restless]

How long for another study to come out that says the exact opposite?

[Graybeard58]

I’ve been drinking one to two gallons a week of whole milk and/or Half and Half for as long as I can remember.

I hope that this doesn’t mean that I will die young. I’m only 77.

Ha....just been through the prostate exam thingy

Probed with an ultrasonic dildo....several index fingers....and a consultation with a Surgeon whose specialty is Urology.

My PSA is 5.4

Dr said....."you have a great Prostate for a 60 year old"

Thanks doc....but I was 60.... 20 years ago.

I drink a lot of milk, yogurt and eat several eggs a day...exercise with weights and lap swim half a mile every week.

[SaveFerris]

I love Vitamin D Whole milk
