Where does one find mechanically produced vegetable oils? I'm piqued, thanks in advance.

Olive oil is the most obvious one

As someone who has had to do IVF for our child and go through the challenge of figuring our what to do to try and improve sperm quality, I can tell you once you start looking into it, basically everything about modern life is bad for sperm. Heat, radiation, plastic, micro plastics, soya, tap water, Teflon, antibacterial soap, underpants, western diet. It’s a perfect storm. If you’re going though it though I offer a r…

Weight loss and proper exercise will probably deliver 99% of the improvements for 99% of the people. Stressing about heat, radiation, micro plastics, or other random stuff seems like extra stress for not that much benefit. Most people in Western world are either out of shape, or straight up obese. It makes sense that, that will have huge negative effects on fertility.

We tried for several months but after starting and following a workout regimen for a few weeks... it just happened!

It's amazing what a little exercise can do for your body!

Big mechanical squishers squishing olives.

In my experience, Teflon will always be scratched. Yes, in theory you could "use it correctly", but nobody ever does. So it's better to simply not have them.

Whats a good alternative? The ceramic ones?

Stainless steel for most things (can't make eggs/pancakes though, they'll stick). Preheat the pan before using. After cooking, warm up some water in it and scrap away the stuck bits with a wooden spoon (or make a pan sauce).

Cast Iron or High-Carbon steel for steaks, eggs/pancakes, stir-fries (wok). You will have to maintain a non-stick seasoning and that has a learning curve, most people don't get it right at first. Make sure to always dry them as they can rust.

You can look at enamel or copper if you have the $$$.

Look for “expeller pressed” on seed oils (canola, etc).

Now I see why they’re advertising the method of extraction...

Good parenting is forcing your boy children to take cold baths because you need their sperm to carry on your legacy.

Good parenting is adopting rather than creating new life. Birthing a child is the single worst thing a couple can do to the environment.

Then the intelligent people who should be having kids are not. We need smart people to fix problems, especially related to the environment. If all the low IQ people keep pumping out babies you can kiss the precious environment goodbye.

Soy isn't that easy: https://www.health.harvard.edu/newsletter_article/Medical-me... There was one study with 99 participants. A counter argument is Asia, where men eat a lot more soy and don't have reduced sperm count.

They've also eaten soy for much longer than others, literally thousands of years(1) at this point. That's more than long enough to evolve countermeasures if it did have an effect. They also eat soy differently, mainly in products which are fermented. 1) https://en.wikipedia.org/wiki/Soybean#History

They also ferment a great deal of the soy they consume.

Based on random website I found googling, it starts to break down and release PFOA around 300F, which is easy to achieve if the pan is not filled with water.

Do you have your units mixed up? Wikipedia seems to have a different range: >While PTFE is stable and nontoxic at lower temperatures, it begins to deteriorate after the temperature of cookware reaches about 260 °C (500 °F), https://en.wikipedia.org/wiki/Polytetrafluoroethylene

I used a different source than the one you link. 500F is not difficult for a frying pan to reach either.

The same Wikipedia page also reads:

>Pyrolysis of PTFE is detectable at 200 °C (392 °F), and it evolves several fluorocarbon gases and a sublimate.

My completely unscientific, unsubstantiated guess, based purely on obsessively researching food safety for years, is that it begins to leach at a much lower temperature.

Some time ago I realized that modern life wasn't that good for your health so last year I bought a farm on the country side with my gf and now we are trying to grow our own food and make our way into a more self-sustainable life.

Why do you think the solution is farm life and not something more primitive?

Absolutely agree that being generally healthy will make a difference.

But what if you aren’t over weight and already fairly healthy, like I was?

Then you have to look at other things too.
