Dairy

[Spaceman210]

Do milk, cheese, yogurt, etc. from goats or sheep happen to have any less tendency to fuel PCa than dairy from cows?

I don't know the answer to your question but, as far as liquid milk is concerned, other alternatives include soy milk and almond milk. Maybe someone else in the forum can chime in on this.

It depends on what you imagine the culprit is, if there is one. I've read opinions that it's the calcium, the butterfat, the casein, estrogen (from pregnant cows),lactose, leucine (an amino acid that is part of whey). Or it may simply be that the near universal use of refrigeration in the 20th century has caused us to consume far larger quantities of dairy products over our lifetime than our bodies have evolved to accommodate. Since there is no evidence that cutting consumption of anything but whole milk now has any benefit, I think it's prudent to limit dairy consumption, but there is no evidence that going overboard will accomplish anything.

Thanks as always, Allen. It sounds as though you're persuaded, to a degree, by evidence that cutting whole milk has a benefit?

I drink 1% milk - for my waistline and my heart.

TA's list omits IGF-I (insulin-like growth factor-I).

IGF-I is a growth hormone. Bovine (cow), ursine (sheep) & caprine (goat) IGF-I are each bio-identical to human IGF-I.

It's crazy to ingest a human growth factor when one has cancer of any type, but IGF-I is a particular problem for men with PCa.

PubMed has 522 hits for <prostate "IGF-I">.

From 2016 [1]:

"... we pooled individual participant data from 17 prospective and two cross-sectional studies, including up to 10,554 prostate cancer cases and 13,618 control participants."

"Our collaborative study represents the largest pooled analysis of the relationship between prostate cancer risk and circulating concentrations of IGF-I, providing strong evidence that IGF-I is highly likely to be involved in prostate cancer development."

While I do understand that association does not prove causality, we are hardly likely to get the kind of study that would convince the purist. Who would agree to be in the IGF-I arm?

The only advice I got from 2 MOs including Dr. Morgans at Northwestern was eat heart healthy.

Well, if the sheep and goats are antibiotic/IGF-free, they at least have that going for products made from their milk. But in the end, it seems to me that dairy is dairy, regardless of the source. And humans are still the only animal species that continues to consume milk from other animals after weening off our mother's milk?

Unfortunately, the research for dairy and PCa is all over the map, with some studies indicating that whole milk is worse and others that non-fat skim milk is the culprit. Still others show a benefit for dairy?. The bottom-line is that, like most all nutrition research, it is difficult, if not impossible, to isolate one nutrient or food source and control all the multitude of other dietary/lifestyle factors that might also affect outcomes. So much for the value of reductive reasoning when it comes to what we eat, so we all are tasked with doing our own research and making our own dietary/lifestyle choices. Michael Pollan may have it right when he says that the best route is to pick a traditional diet, like the Mediterranean, since if it was not supportive of good health, the people following it would have died out hundreds of years ago.

The following article from The Atlantic sheds some light on the topic. (In particular the last quote from it sums up the topic quite well):

"I think Bertrand Russell nailed it," Katz told me, "when he said that the whole problem with the world is that fools and fanatics are so sure, and wise people always have doubts. Something like that."

That was Doc Myer's perspective.

His logic was based on consumption of corn

Sheep and goats don't ever eat corn. Apparently corn and animals that eat corn end up increasing your arachnoidic acid levels. Which promotes prostate cancer growth.

Somehow this doesn't apply to chickens.

But this issue is grass fed is always better.

During my six month chemo-hormone therapy trial, absolutely zero dairy products of any kind were my instructions. I followed my MO’s instructions.
