What I would do for cultured dairy.  All you As, Bs & ABs rejoice; yogurt is really good for you.

heal the gut :)

What about Amande yogurt?  I think I spelled that right..... it's a yogurt made with almonds?

check ingredients

if there are gums or additives, make your own best

You can get some of the benefits from  lacto fermented veggies as an O .

Interesting enough they are talking here in DK  about that all babies born after a c section should get probiotic after birth = less problems with allergy and infections.

sorry, are you talking about soy yogurt or milk yogurt?

Interesting that the comany's web site doesn't tell you the exact ingredients in their products.  They are "fruit juice sweetened."

From THE COMPLETE BLOOD TYPE ENCYCLOPEDIA Page 266

In the large intestine, the emphasis is on elimination, thought a bit of assimilation does take place-principally electrolytes like sodium and potassium and a few  vitamins.  Large quantities of ABO blood group antigens are found in the gastrointestinal mucosa.

Blood group is an important influence on the growth of particular strains of bacteria in the large intestine.  Many bacteria consume blood group antigens, and blood groups are extensively expressed in the human large intestine.  The upper colon contains very large amounts of blood group antigens, which gradually diminish to nothing at the end of the colon.  This probably reflects their use as a food source by the colon bacteria; as debris passes through the colon, fewer and fewer nutrients can be found in it.  The depletion of blood group antigens is just another aspect of this phenomenon.

The composition of the normal flora varies somewhat from individual to individual.  Some bacterial species may be carried only transiently.  Most are fairly permanent-- animal experiments have shown that it can be extremely difficult to alter the composition of the normal flora of the gut in a healthy person.  Many of the common bacteria choose to live in the colon of one blood group or another(18).  Sometimes this is because the bacteria can mimic the blood group of their host, and so are viewed as "self" by the host's immune system.  In other circumstances, certain bacteria have a taste for one particular ABO antigen over others and prefer to nibble mucus containing that particular blood group antigen(19).  Some bacteria more easily adhere to the mucus on one blood group over others because they themselves make lectins which they use to attach to the walls of the colon, (remember, lectins are nature's glue) and these lectins are usually specific for one blood group(20).

The difference in colon bacteria and the presence of blood group antigens in the colon are among the reasons that different blood groups seem to do better on  different types of fiber.  A sign that you are taking the wrong fiber is gas, or flatulence.

This is why some here are recommending fermented veggies for O's (from the individual's superfood or beneficial list) or making your own almond yogurt (to ensure there are no gums or added avoids) is because not all probiotic's are good for all blood types.

Sharing with the best of intentions.

Yogurt made from almonds.

As O gatherer I am allowed Quark.. I think it is time to make my own.. Yogurt is not on my food list but .. quark seems to be.
