Hi guys, while this isn't a primal or paleo questions I have gotten to know some of you and trust your advice. Plus your recipes would match my food choices.

So do you ferment your own or buy them? Is this something everyone should do? It seems to make logical sense from what i have read to be healthy. My other thoughts are is it necessary to buy cultures each and every time? I remember my grandma had "friendly fruit" a tub of fermented fruit in the fridge that was off limits to us kids they said it was alcoholic.

I am completely new to this and have a billion questions like how to get started which led me to this video, "buy our stuff" http://healthylivinghowto.com/1/post/2014/03/a-beginners-guide-how-to-ferment-vegetables.html

Will my kids destroy the batch if the stick their fingers in it? So you really have to wash, then vinegar every thing your using. Is it dangerous to make your own?(if your breeding good bacteria what about the bad)

Anyway I have been thinking about this for a few weeks and reading and am almost ready to take the plunge, (especially a salsa) or something I can put on my eggs. Do you eat your pro-biotic/fermented food daily, 2x daily, is their a safe limit or can you eat as much as you want?

Sorry if this was a bit vague and all over the place just trying to understand this process, and why people do it, as well as how to do it, if it is indeed as beneficial to gut health as it seems. I have a wife with IBS, and a son who has a ton of GI problems and has been under the care of specialist for over 5 years, who keep coming up with nothing helpful next is surgery (not until he goes grain/dairy free for 100% for 3 months). My wife has already seen improvement with here IBS with primal eating, now my son is 100% primal with limited dairy (max 2 servings per 2 hrs) dr's orders.

Thanks for your experience, recipes and options, they are truly appreciated.
