hi ph,

my mom is old school korean and makes her own soy sauce from scratch. when it's fermenting, the soy looks and smells really bad. ha, my non asian friends in high school made fun of me b/c it looks like little towers of dried poo.

anyhow, would this be acceptable under paleo?

i do avoid the store stuff... that's not realy soy sauce!

I don't think he's going to make soy sauce his staple.

The phytic acid and enzyme inhibitors go away with fermentation. In fact, soy sauce is traditionally brewed with myco-cultures that aid in protein digestion. Check it out: http://en.wikipedia.org/wiki/Soy_sauce#Traditional

Phytic acid is not the only problem with soy.

Is the paleo blanket ban on soy rooted in reality? Nope. Homemade fermented soy sauce sounds wonderful.

Check out this beautiful graph of phytic acid levels going down as the soy gets soaked, boiled, steamed, fermented, & more fermented http://foodgraphs.net/food/phytic-acid.html

Update: Here is another paper which contradicts the above on how fermentation affects antinutrients such as Trypsin Inhibitors, Phytic Acid, Saponins and Isoflavones. The conclusion: "With the exception of the trypsin inhibitors, the compounds reviewed here generally are stable to processing of soybeans as practiced today"

I personally add organic white miso (another form of fermented soy) as a dressing & soup base quite frequently. Don't think my taste buds will ever go back to tempeh after this.

If it contains soya then it's not Paleo in my book, but this being Paleo-hacks, feel free to define Paleo in any arbitrary way that suits your diet:

"[Soya] has many problems, like its phytic acid, lectin, phytoestrogen, and enzyme inhibitor content, and the fact that most soy is genetically modified"

etc, etc, etc

Being pragmatic, if you have to choose, home made towers of dried poo are always going to be better than mass produced towers of dried poo. But they will always be towers of dried poo, no matter how you dress them up.

Great question. If it is fermented and wheat free, AKA tamari, it is OK in my book but strictly speaking it is not Paleo.

I would avoid whole soybeans, soy milk, soy additives (because you don't know what's been done to them) etc... Soy shouldn't be a staple.

That said if you want a bowl of miso with your sushi and do some wheat-free soy on your sushi a couple times a week? No prob. Your shampoo probably has more xenoestrogens then the soy sauce.

My MIL is old school Korean and if she ever bothered to make me homemade soy sauce, I'd definitely eat it. I'd also make her do it far, far away from my house because cooking soy sauce smells awful.

But it's not by definition "Paleo", but it's probably better than storebought.
