Continuing with the topic of the blood type diet, the claim
has been made that lectins are important regarding health.

Here is a research abstract about a kind of lectin that appears
to protect cancer cells:

Aren't lectins natural and thus all good for you?
So no matter what your blood type is then I guess you should stay away from
lectins? Or only if you are type A?
I don't see anything in the article mentioning eat for your blood type or
blood type even mentioned. They sound like ignorant doctors not knowing
about eating for your blood type.

Yeah, anything natural is good. Like:
The natural products of Clostridium botulinum.
Or maybe, tobacco. That is natural
Nightshade extract (Mmmmm, atropine).
Lecitins are basically phospholipids (PI, PC, PE), so yeah generally no
harm. I think they are used as an emulsifier in foods. Some recent research
(see last months Journal of Lipid Research), shows that soy lecithin can
reduce cholesterol levels and improve HDL to LDL ratio. Even though these
were human trials (which means small numbers for short durations with lousy
control--that is the nature of the beast with humans), much more works needs
to be done for any real conclusions.

Snake venom is also natural. Is it good for you?

lectin (lec·tin) (lek¢tin) any of a group of hemagglutinating proteins
found primarily in plant seeds, which bind specifically to the branching
sugar molecules of glycoproteins and glycolipids on the surface of cells.
Certain lectins selectively cause agglutination of erythrocytes of certain
blood groups and of malignant cells but not their normal counterparts;
others stimulate the proliferation of lymphocytes.

phosphatidylcholine (phos·pha·ti·dyl·cho·line)
(fos²f[schwa]-ti²d[schwa]l-ko¢l[emacr]n) a phospholipid in which choline is
attached to the phosphate group of phosphatidic acid by an ester linkage; it
is a major component of cell membrane and is localized preferentially in the
outer surface of the plasma membrane. Abbreviated PC. Also called lecithin.

In clinical practice A1 Lectins (Dolichos biflorus) are used in typing blood
for the A1 blood type. Those patients that are A1 negative and or type A2
and other subtypes of A will not react with that lectin. 22-35% of Type A2B
individuals have an anti-A1 antibody.

PC is quantitated in amniocentesis fluid in determining fetal lung maturity.

Nature has given us this for our use. Russels vipor venom is used to test
for lupus anticoagulant in clinical practice.
Reptilase, venom of the pit vipor Bothrops atrox, is used in a clot based
test system for neutralizing heparin effects.

Cobra snake venom reduces significantly tissue nucleic acid levels in human
breast cancer.

Jokhio R, Ansari AF.

Department of Pliysilogy, University of Sindh, Jamshoro.

OBJECTIVE: To look into the feasibility of using cobra snake venom in
suppressing breast cancer tissue through inhibition of nucleic acid
synthesis. METHODS: Samples of breast cancerous tissue, obtained from Atomic
Energy Medical Center, LMCH, Jamshoro, incubated with varying concentrations
of venom and without venom (as controls) were assayed for macromolecular
(RNA and DNA) levels RESULTS: No. change in the control samples while a
prominent and significant fall in nucleic acid contents has been noted in
venom treated tissues. Also, maximum effect was observed with 25ug/ml dose.
CONCLUSION: Snake venom strongly inhibited the formation of nucleic acids in
the breast cancerous tissues. It may bring a fall in cell proliferation,
thus there is hope that venom could be used as an anti-cancerous drug in the
future.

Yeah, sorry I thought the lecitin was a typo (the study I referred to was
lecithins, of course.). That is an outdated name for the phospholipids, but
you still see it used (mostly in the natural food industry).

Nature has given us stressor substances (such as fish oil) and
anti-stressor substances (for example, antioxidants). Our powers of
reason should allow us to determine which should be used under specific
conditions, but that does not always happen, for example, because there
is money to be made in selling "supplements." I recently posted a
paper about the atherogenic qualities of peanut lectins. Generally,
lectins have stressor qualities, so I avoid them, especially in
legumes. I do eat a bit of soy tempeh, because it is fermented and the
lectins are no longer a major problem.

With regard to the OP:

When it is said that something is "anti-cancer," that is not saying
much. Killing cancer cells sounds good, but if the healthy cells die
too, what have you accomplished? What you want to do is to enhance
your body's natural defences against cancer, but this has been
obliterated in Western societies because high omega 6 polyunsaturate
consumption leads to excess PGE2 and LOX5 metabolization from AA, and
this sets up a perfect situation for cancer. You need to get the AA
out of your body first and foremost, and while doing that, you should
eat antioxidant rich foods and avoid polyunsaturates and oxidized
cholesterol, and make sure you aren't getting too much iron, even from
your cookware.

The point that has been made elsewhere is that
the immune system normally attacks cancer cells.
However those lectins were preventing that.

At some point in the pathway that is called "cancer," lectins might
have "good" qualities, but at another point, they may have "bad"
qualities. The key is to avoid stressors as much as possible. In
general, lectins seem to intefere with improtant processes in animals,
and so should be largely avoided.

Don't mix lecithin and lectins.

Unboiled seeds of several types of beans, especially wild ones,
contain lections that may even turn fatal.

Here is one on mung beans. Jerusalem artichokes also contains lectins.

You have to avoid all food otherwise your red cells will agglutinate.

That's the problem around D'Adamo. He never has proven that.
It is not correct.

But then nobody has ever proven that food makes you full either. Can you
show some sites or cites of that?

So what? Other people have. Look on PubMed.

Alf,

The last time I had a look about the blood group diet in PubMed all the few
published studies were in Norwegian (no abstracts in English). I would like
to know if you have ever had a look at them and what is your opinion of
those studies.

Who searches PubMed for diets? You should search for "lectins".

I do. Interesting studies about whole dietary patterns have been made.

I have done that search also. However, the existence of lectins does not
prove the blood group diet.

Don't you remember that lectins agglutinate your red cells and should be
avoided?
I mean those with Type A blood types.
