All food of animal origin contains hormones.

But most of our dietary exposure to hormones comes from dairy products.

By quantity, it's mostly prolactin, corticosteroids, and progesterone.

There are also a bunch of astrogens, which then concentrate further when you make other dairy products, like five times more concentrated in cream and cheese, 10 times more hormone

concentration in butter.

So when it comes to exposure to steroid hormones in the food supply,

about three-quarters of our exposure to ingested female sex steroids comes from dairy,

with the rest evenly split between eggs and meat and fish.

Eggs contribute about as much as all meat put together,

which makes a certain amount of sense since it comes straight

from my hen's ovary, right?

Among the various types of meat, you get as much from white meat, fish and poultry, as you

do from pork and beef.

And this is just from natural hormones, not added hormone injections like

bovine growth hormone. So for these, it doesn't matter if the meat's organic. Animals

produce hormones because they're animals, which understandably ends up in animal products.

But only about half of people surveyed seemed to know that, lacking basic knowledge,

like not realizing what milk is for.

Cows only give milk after having a calf.

So these researchers suggested we ought to inform the public about dairy production practices,

to which one journal of dairy production practices, to which one

journal of dairy science respondent wrote, you know, telling the public all our new technologies
