Dear Hubby's (Type B) blood pressure and heart rate have been going down, down, down;  heart rate down below 50 most of the time, to the point he woke up in the middle of the night with the sound of blood rushing in his ears, took BP and found heart rate was 42!  Scary!  He had stopped his BP med (with Dr approval), but pulse was STILL very low.   So he asked if there was an herb he could take that was a heart stimulant.  Google-google ... we ended up him taking ONE YOHIMBE  pill.  Heart rate straightened up to 57 or so and continued great all day and on to next day (today).  Only "down side," from my point of view, was a bit of slightly "pressured speech" and just some little signs of a kind of "hyper" behavior he sometimes gets into, but has not been doing (much) for quite awhile now (probably thanks to Type B Diet).

ANYWAY, what with all the googling, this page has (at its bottom) a table of foods high in Tyramine which should NOT be eaten by people on MAOI's (DH ain't on MAOI's) (but maybe 'cause he's a Type B, it's LIKE he's on MAOI's???) and this chart has a whole lot of things on it that Type B's are not s'posed to eat according to BTD.

There's some kind of thing going on with

Tyramine is generally produced by decarboxylation of the amino acid tyrosine during fermentation of food products. All protein-rich foods which have been matured will contain more tyramine depending on the temperature and how long they have been stored.

Protein from such sources as meat, nuts and egg whites are broken down by the digestive system into amino acids such as l-tyrosine, a precursor to dopamine, which is in itself a precursor of norepinephrine.

As a stress hormone, norepinephrine affects parts of the brain where attention and responding actions are controlled. Along with epinephrine, norepinephrine also underlies the fight-or-flight response, directly increasing heart rate, triggering the release of glucose from energy stores, and increasing blood flow to skeletal muscle.

However, when norepinephrine acts as a drug it will increase blood pressure by its prominent increasing effects on the vascular tone from a-adrenergic receptor activation. The resulting increase in vascular resistance triggers a compensatory reflex that overcomes its direct stimulatory effects on the heart, called the baroreceptor reflex, which results in a drop in heart rate called reflex bradycardia.

You know, the more I read this kind of stuff, I wonder whether there might be a FOOD-related cause for "unrest" in the Middle East ... they eat a lot of fava beans over there, eh??  for instance ...

I would like to know if Type B's in general are sensitive to foods high in tyramine?

Glad to see your MD is aware of his heart rate. Wow that he  great that he is off his B/P meds.
Wearing a 24-48 hour holter monitor will elimninate a mechanical cause of the slow heart rate ( bradycardia).

Hawthorn :-/? or    NO?

Take a look and see what ya think.

Andrea, yes, he did the halter monitor thing three days ago.  

But one pill of yohimbe worked.  I'm kind of scared of the yohimbe being too strong, though,  maybe COQ10 would work, too?  There are quite a lot of "herbal-supplement" stimulants.  Today we broke one pill of yohimbe in HALF;  he only took half this a.m.  

And Andrea, THANKS for that link!!  It is quite complicated and I'm going to have to think about it and re-read it a couple of times;  but it is interesting that Type B's are differentiated from the rest of the population in ...:

the responsiveness of respiratory patients to nitric oxide (NO) therapy. Apparently, those types with a B antigen (types B and AB) have less success with this therapy.

and L-arginine is one of the two aminos that B's "deal with" from milk products (can't remember the other amino?) that there is a perfect balance of from the milk?

Aren't there a lot of Jewish Type B's?  and maybe high percentage of B's in Middle East?  (just a thought ... nitric oxide, eh?)  sometimes it seems like that area of the world is "on steroids," eh?  Or maybe "on norepinephrine!"

Also interesting about the nitric oxide function being behind the action of Viagra ... maybe yohimbe does something to nitric oxide function, too?

LR4YT, pg. 28 on nitric oxide function in Bs

also read the nomad monogramm.....
Metabolic Profile
Quoted Text
Their uncanny ability to control nitric oxide activity is at work with their ability to 'think' or visualize their way to better health. Nomads are the patients who get dramatic healing results from meditation and mental exercises. The ultimate example of a mind-body connection.
