I just read in one of Dr. D's books that the milk sugar D-Galactose is also the blood type B surface antigen.

Along these lines, are there any foods that naturally contain the Type A antigen N-Acetyl-D-Galactose amine?  Would such a food be not reactive to Type A's?

Have you tried some google searches?

the A antigen is simply N acetyl Galactosamine...without the D.

blood type B surface antigen is D- Galactosamine.

check out page 19 of ERFYT.

The sugar that is on the end of the type A antigen is N-acetyl D-galactosamine. Eating a food or supplement with this sugar would be good for type A and AB, not reactive in a bad way.

Quoted from N-Acetyl-D-Galactosamine - Dietary Sources
http://www.chem-online.org/carbohydrate/acetylgalactosamine.htm

   * There is an abundance of N-acetylgalactosamine found in Bovine and Shark cartilages. However, Shark cartilage should not be consumed by those with diabetes or kidney disease.
   * It is also found in a red algae called Dumontiaceae, as a constituent of dextran sulphate; but, so far, this is available only from Japan.
   * Although Shiitake mushrooms contain N-acetylglucosamine, they do NOT contain N-acetylgalactosamine.
   * N-acetylgalactosamine is also constituent of Chondroitin sulfate, a useful sugar but not essential, which is often combined with Glucosamine in the treatment of osteoarthritis. When Chondroitin sulfate is used with Glucosamine sulfate, the absorption rates of both is dramatically increased.

Thanks, Lola.  Great picture, by the way.

Thanks, MoDon.  I had found that earlier, but I was hoping maybe there might be a more common food.  But knowing that a certain red algae contains the molecule is a good thing.  If it could be cultivated and brought to America like bladderwrack, might that not be a very favorable thing for A non-secretors?

thanks R.!

how' s your Spanish?

Although not a food, type As can get N-Acetyl-D-Galactosamine by buying Deflect A.

deflect is N acetyl D glucosamine Don, not galactosamine.

True, but N-acetylgalactosamine is also constituent of Chondroitin sulfate, which is in Deflect A.

yeah, and that s the reason O s are not advised to supplement with Chondroitin.

Quoted Text

Chondroitin sulfate is largely broken down into its repeating components, N-acetylgalactosamine and glucuronic acid.

Quoted Text

As you no doubt also remember, the terminal component of the A antigen is n-acetylgalactosamine; the same protein sugar that is a building block of chondroitin sulfate. Glucosamine on the other hand can be readily converted into galactosamine, the terminal residue of the B antigen.

Quoted Text

Well, since most lectins that are specifically detrimental to blood type A are bound and inactivated by N-acetylglalactosamine, this means that chondroitin sulfate is an excellent strategy for an A or and AB. But since blood type O and B are not impacted negatively from blood type A specific lectins and because O and B make antibodies against things that look like blood type A, chondroitin sulfate might not work as well for these people.

and last but not least:

Quoted Text

One of the simplest biochemical reactions that occurs to glucosamine results in the formation of galactosamine, a substance that with tend to protect B or AB from lectins with blood type B specificity. Glucosamine can also be acetylated to form N-acetylglucosamine, the protein sugar specific for binding the very disruptive lectin found in wheat. Since wheat seems to be particularly difficult on blood type O, binding this lectin is a good strategy for O's with arthritis. Giving N-acetylglucosamine directly would probably be an even better
strategy for O's.

Marine Red-Algae is simply phylum Rhodophyta....of which Dulse {Palmaria palmata} is a member. Irish Moss and Carrageenan are also. Here in UK there is also freshwater varieties {Lemanea spp.}. Red-Algae does not necessarily need to be red in colour.

Dumontiaceae sp. is of the order Gigartinales of the class Florideophyceae in Phylum Rhodophyta...

Apparently, there is some Waernia sp. of Dumontiaceae off the coast of northeastern North America. Gainia sp. and Blinksia sp. off the coast of California.

I thought Shiitake was N-Glucosamine?

---

There are various structural isomers of N-Acetylgalactosamine and N-Acetylglucosamine of which the stereoisomer N-Acetyl-D-Galactosamine is part of the B-type.
Intersestingly the variety of rare A-Types {A₁, A₂, anti-A, etc.} have differing numbers of galNAc and GlcNAc in the chain, but the ends are all the same...and as some A₂ can be mis-typed as Bs this would be a good indicator of various Lactose intolerance levels of individuals with an A  

oups...if so, MoDon why do I react with lactoseintolerance...not only because I'do have not the lactase enzyme !....I guess

Hi gang,

I've been using an MSM cream ... to take away the pain from some skin lesions.  It was very effective in doing this, but as well a high increase in diarrhea seems to have paralleled the use of this MSM cream.

In using MSM was I doing something similar to taking chondroitin?

John

D'Adamo says MSM is a type O avoid because it is a sulphur compound and the typical type O diet is already high in sulphur. However, MSM is a unique form of sulphur and probably is metabolized differently than other sulphur types. .....
so ........it s up to you.......thoughts?

If John is using it topically, it shouldn't be an avoid issue.

didn t think he is using it topically......since he asked about it being linked to chondroitin as an A.

This is what gives me the idea he is using it topically, on skin lesions.

right!  lol
thanks Victoria for pointing that out!

No problem, sister!

Lola also posted this link in another thread:

Stephen's post

Hi Victoria and Lola,

I am using this topically but MSM (like DMSO) may be unusual because of its ability to penetrate deeply, even if used topically.  DMSO is in fact so penetrating it is used as a 'carrier' to permit the topical penetration of substances that are usually blocked by the skin.  

Will have to see how long this persists.  Hopefully, it is out of my system by now.... yesterday was quite a day!

John

John, maybe you just overdid it.  If you got benefits from the MSM otherwise, you could try using it more sparingly after your digestion settles down.

That's a good point about the absorption, but I still believe the BTD issues come through the digestive tract.  But MSM on it's own may be laxative.  I know if I use too much orally, I can get gassy from it.

thanks R.!

how' s your Spanish?

Lola,

Considering that my ancestry is Spanish, Italian, and French, I should probably know more Spanish than I do... particularly when talking to hottie Spanish ladies.  

it s never too late to brush it up! lol
