This little blog post actually did a pretty good job of parsing the information. There is a lot of estrogen in a lot of foods.
To add; soy gets a bad rap because it’s heavy in isoflavones. Those are precursors to all sorts of hormonal responses in people (& animals). But in a “normal” diet there is no harmful affects for most people or animals. Effective diet control can be summed up by “Eat food. Not so much. Mostly plants.” Micheal Pollan
Actual chemical residue in commercial food in the USA is really not an issue to be worried about. From personal and professional experience, be more worried about fungal, viral and bacterial contamination …
I can also guarantee that if commercial grain products fed to our livestock was a problem, there’d be howling so loud it’d block the sun.
Side note and questions to anyone worried about chemical residue in foodstuffs—
What is in your water?
Do you test?
Do you request test results from your municipal supply?
Do you filter your tap water?
Do you clean/sterilize all water supply equipment on a schedule?
If you collect rain- does it collect from a sterile/clean surface?
Do you store it correctly?
There is a whole lot in our water supply that should get much more attention.
And, if you and your animals aren’t drinking reverse osmosis water, well, you’re drinking all sorts of drugs/hormones, chemical run off, bacteria, funguses and viruses.
Watch out for that di-hydrogen monoxide poisoning.
