Was directed here to share my experiences in the fermented foods world... Here's a bunch of information from it. *grin*
Wild Fermentation is a great book. Wildfermentation.com is alive and kicking with additional information. *grin*
The Book of Miso and The Book of Tempeh are VERY informative and highly recommended.
Tempeh! Food of the Gods. *grin*
I make Tempeh according to the book of Tempeh and use various beans. Since all blood types can't eat soy, it helps to know which beans you can use for which people. *grin* (
Here's a list of foods and their compatibility with blood types)
Hint: Great Northern Beans are neutral for ALL blood types and makes a super delicious tempeh when fried with just olive oil. *grin* VERY tasty... heheh my 2yr old munches fried pieces for breakfast and loves it.
I've made Kidney bean tempeh for my "B" blood type wife... really needs to be cooked and then used in other foods as a filler. Not bad... just not that palatable to her. Digests really well though
Black bean tempeh! Oooohhhh my goodness! Sucks trying to remove the skins... but daymn is it ever tasty. *grin* A and O blood types only for black beans though... avoid for everyone else.
Soy beans are the easiest to de-hull and is compatible with A and AB blood types... O and B depend on their secretor status (another level of complexity for the blood type diet)
Depending on the bean... and the innoculant you're using... it can take between 24-36 hours to incubate fully. The northern bean creates a really heady alcoholic smell to it. Again... it's damn tasty. *grin*
Hardware stores sell a thermostat controlled outlet... handy when building a dehydrator or incubator. *grin*
Miso! Wow!
If you haven't had homemade miso... you're missing out. Most commercial products are poorly made and the majority of the flavor pressed out to make Shoyu or Soysauce... they sell it separate.
I have a 5 month northern bean miso in the fridge that's almost gone.... the complexity of the flavors are just divine. *grin*
Gonna be on commercial miso for months again. *sigh* My fault for not making more.
Miso is basically steamed rice innoculated with starter, incubated for 3 days and then mixed with steamed or boiled beans and salt. Packed in a crock, a cover and weight are placed on it and the top covered with paper or plastic wrap... fermented until done.
As with tempeh.... the blood type of the person determines the bean you can use with miso so they don't have issues. (Haven't tried kidney bean yet. LOL)
I stick with northern beans for the family, we have A, B and O in the house. LOL
I have yet to sample a black bean miso... can't wait though.
Depending on the amount of Koji (the cultured rice) and salt you add, the miso fermentation process can be as quick as 1 month or as long as 3+ years. The book of Miso author stated they had some 9 year old miso once.... can't even imagine how cool that would be. Imagine the flavor chains that would be created in that time. *grin*
Miso is a very alkaline food. During the fermentation process, the carbs and proteins and flavors are broken down into their base molecules... Drinking a cup of hot water with miso paste stirred into it is like instant nutrition for your body... no need to digest, just absorb! *grin* Better than a cup of coffee, when your diet is clean. *grin*
Saukraut! Kimchi!! Wow!!!
I love the stuff but it jacks my mucus secretions up so high it's outrageous. LOL Not compatible with the A Blood type or with O Non-secretors. Anyone else can eat all they want.

The store saurkraut is often made with a chemical process... anything in a can or jar is dead from the canning/jarring process and really isn't much more than flavor and texture. All the beneficials from the fermentation process that would aid digestion are dead. *shrug*
They're very easy to make, recipes abound. The more salt you put in the cabbage... the longer it will take and the more sour the end kraut/Kimchi will be. Too much salt though and nothing will ferment. *grin*
Anyone with health problems will do themselves a world of good by following the blood type food choices.. the more fermented foods, the better. The key is to achive an alkaline state in the body so that your immune system, blood and organs all work at optimum levels.
Tempeh supplies Vitamin B's and carbs/proteins that have been partially broken down already. Much easier to digest and the B vits really help with muscle soreness after a long strenuous day.
Miso, Saurkraut and Kimchi all supply salt resistant enzymes and yeasts that are beneficial for digestion... Not to mention divine flavors.
At the end of the day... I drink a glass or two of my wine or mead and I'm good.

LOL
End result of fermented foods and choosing my foods by blood type?
I'm 41 years old.
I've been following the blood type food choices, on and off, for 10 years.
In the last 2 years I've gotten more and more serious about being strict and in the last 6 months I've achieved it. No processed foods, no foods that are avoid for my blood type. (A secretor)
My digestion is stable and very predictable... 100% reversal from what it used to be.
I feel good after I eat... every time I eat.
I sleep between 4-5 hours a night and HAVE to get up as I have too much energy. Sleeping in is no longer something I can do... LOL
My waistline has dropped to around 27 or 28 inches... (been 28-34 my whole life) I need to buy new pants, I've added 4 notches to my belt, should find out what size I am in the next few weeks.
I live at 2 miles above sea level and can power walk... up and down hills without breaking a sweat. *grin*
I used to be sick at least 3-4 times a year... for a few weeks. I haven't been sick in over a year. LOL Yeah.. maybe the sniffles for a day or two, but nothing that slows me down or that I can really 'feel'. *grin*
My hair and nails are in wonderful condition... for the first time in my life. Started getting strong and healthy as soon as I eliminated all red meat... The A blood type can't handle it. Heh.
Yeah... I highly recommend fermented foods and the blood type food choices for everyone, especially anyone with health issues.
Can't guarantee that I'll be able to respond timely... but I'll definitely, eventually, answer any questions directed to me. lol
Happy Fermenting!
p.s. I tend to wander all over at times... apologies for any confusion. lol
