Diet - Eggs or no eggs?

Posted by zooblio6 @zooblio6, Jan 28, 2025

I am just beginning ADT ( Gleason 7 4+3 T2a ) and see the oncologist tomorrow here in France to set out the RT plan. No dietary advice so far from eg urologist and guessing that tomorrow will only be a practical regime for the duration of the RT. Respected sources constantly recommend a plant-based diet ( already on this ) with little or no dairy products. However, the court seems to be out in the matter of eggs. This concerns me, since B12 is clearly important on all fronts and calcium is clearly an issue with risk of bone thinning whilst on ADT.

Has anyone here received advice for or against please?

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

That's interesting. However, I will go with a 2 egg omelette and throw in some mushrooms.

@johnwf The research says that a chemical ("choline") that appears in eggs also appears in elevated levels in the bloodstream for people with more-serious types of prostate cancer.

That's not proof that eggs are dangerous for prostate cancer, though, especially since the liver regulates choline levels, and can even synthesise some if it gets too low (choline is an essential nutrient; you'd die without it).

The main question is whether high levels of egg consumption cause prostate-cancer recurrence, or whether it's just an accidental correlation: after all, people who consumed a lot of eggs in those studies were also more likely to smoke, ate more red meat, and were more likely to be inactive. So far, none of this has been established in a proper clinical trial.

p.s. Beef liver is also a big source of choline.

@northoftheborder Even the researcher who did the study said possible ‘correlation’ does not mean ‘causation’.
Eggs are also full of so many other important minerals and protein. To limit eating them for a ‘possible but yet unproven’ link to PCa is premature IMHO.
Remember just one year ago eggs were considered deadly for coronary artery disease, then voila! now you can eat 7-10 eggs per week with NO risk to cardiac health.
And this, after 50 years of maligning nature’s complete wonderfood…

That information I posted about the number of eggs that was safe to eat was from the UCSF prostate cancer conference three weeks ago. I have seen other recent sessions where they said eating more than three eggs was problematic. It’s the yolk that’s the problem.

The latest information does seem to say that eggs are not great for prostate cancer patients.

@jeffmarc In the absence of more research, could it be more something like "we don't *know* if the statistical correlation with egg consumption is meaningful, so maybe limit yourself to ≤3/week if you want to stay on the safe side."?

It's mainly the difference between "may be" (caution) and "are" (a high degree of certainty). We tend to jump from the former to the latter a bit quickly in layperson discussions.

I split the difference and have two eggs on Wednesday and Saturday with an English muffin. No Canadian bacon Or hollandaise sauce.

I’ve been doing it for a long time and it doesn’t seem to affect my undetectable reading.

I wouldn’t eat any more.

Uh-oh, I’m in the habit of eating a dozen eggs a week (3 scrambled eggs Monday, Wednesday, and Friday, and one weekend day).

I suppose I should cut that back a little, but that was to replace my usual weekday breakfast of a small bowl of cereal (Cheerios, Wheaties, or Grape-Nuts) until my PCP blasted me for that (“There is no such thing as healthy breakfast cereal! They’re as bad as soda!”)

Hmmmm, where’s my third-stringer… “Yogurt! You’re up! Now get in there!”

@jeffmarc I believe that they posted that. However, one of the studies I read said that men who ate more than ONE EGG PER WEEK had a much higher chance of getting LETHAL prostate cancer…seriously - ONE FREAKIN EGG??
Sorry, Jeff, but I just can’t see how these informational retrospective studies carry any weight.
I mean, there was no double blind study, no 10 year strict follow up; there were only questions: “Sir, do you eat eggs? How many per week?”
That right there is a big false indicator since diets can vary from week to week and memory is not very reliable.
I simply cannot believe that a man who routinely has two eggs on a Saturday morning has doomed himself to die of prostate cancer.

This website has numerous articles debunking many myths about eggs - notably when eggs were implicated in causing prostate cancer because they were high in Omega3 fatty acids - totally FALSE because we know these fats are beneficial!
Also an article about eggs, choline and prostate cancer. Basically everything comes down to how a substance is metabolized in a ‘normal’ situation vs a ‘cancer’ environment.
I realize that this website is probably run by the egg lobby, but sometimes a lobby can be a good thing if there are widely disseminated anecdotal myths that somehow become facts, even within the scientific community. Best,

From my research, it may be advisable to stop eating eggs if you have prostate cancer. I've summarised it here on evidence.zone, a free resource that aims to catalogue the science on interventions for prostate cancer (particularly for active surveleillance). Please let me know if there's more recent research to consider:

I tried to write a reply to this but get a freeze when saving and then get access denied to all Mayo web sites.

It clears up after a few minutes.

Unsweetened cereals like you name are mostly harmless, in moderation.
They are NOT as bad as soda.
Yogurt is not perfect either, lol, since most are sweetened.
Moderation in all things.
