Hello, Zenah! Grapeseed oil is still considered "unknown" since we have not yet tested it for ABO-reactivity. If you wish, you may use it as a "neutral." :-)

How is a green olive different from a spanish olive??? Doug

"Spanish olive" refers to the unripe and mold-susceptible green olive which has been pitted and stuffed with pimiento, then packed up with sodium alginate, calcium chloride and guar gum in salted water. "Green olive" is our term for a whole, unpitted and chemical-free green olive, preferably one bought from a reputable grocer (in other words, fresh & mold-free).

I have ordered the supplements from Dr. Dadamo for type A. Do these supplements take into account secretor status? I am type A non secretor. Thanks Lisa

Absolutely! They are designed to accommodate secretors and nonsecretors alike!

Heidi, how does one find out more information about their bloodtype, beyond what can be done with the home testing kit? Do regular labs do this? Maddy

Well, type As and ABs can get their A or B subtype (for purposes of the diets, only type A2 has some bearing). All of us can get our Lewis type, which usually corresponds to secretor status, as well as the MN subtype. There are some 20+ subtypes for which labs can test, but very few of these results have any relation to diet and lifestyle ~ and some of them are costly.

And yes, most labs are capable of performing these tests, but your doctor may not see any reason to order them. Southwest Naturopathic Medical Center have made things easier for us by designing a blood panel kit for collection and the requisition form to send with it to their lab ~ all you need is the blood draw. They are in Scottsdale, Arizona, phone number 602-970-0000 and fax 602-970-0003. Call or fax a request for their kit if you'd like to get the full panel. They test for ABO, A subtype, Rhesus, Lewis, and MN. :-)

We have purchased most of your books and would like to ask a question. It is: Any stukdies done showing the actual cholesterol (HDL/LDL)#'s that correspond to the 4 different types of blood? Thanks, Shirley

Hi, Shirley ~ blood type does not dictate cholesterol levels, so for example: one type A could have a far lower level than someone who's type B, and another type A could have a higher level than that type B. A person's cholesterol "set-point," or level beyond which dietary intervention is inefficacious, appears to be a hereditary trait quite separate from ABO type. In general, though, type Os can be "OK" with a slightly higher total cholesterol reading (say, 220) than type As (who might be far better off at 180 or under), for instance.

1. Is it a medical fact that different blood types have varying levels of acid in their digestive/elimation tact? What are the statistics for type A versus type O? 2. Is there medical proof that people with Blood Type A have more cancers in the digestive/elimation tact then other blood types? What are the statistics? Stephanie

Hello, Stephanie ~ Well, that would be a lot of statistics to type out here. May I suggest Live Right 4 Your Type's Appendix A (pp. 329-350), which is a list of scientific references for disease and digestive function as correlated with ABO type. Online, you can go to the homepage here (www.dadamo.com) and look in the lower right corner of the page. If you choose "Disease" there are eight links to more pages and more statistics & research. Then go back and choose "Physiology." Nine "modules" there. I think you'll find what you're seeking!! :-)

I went from overactive Thyroid (Radioactive Iodine) to underactive Thyroid function. After two years my medication is doing the job but I'm still not the same person. My body went into a menopasual state (at 35) and I am battling weight, poor libedo etc. What natural things can I take while I am on artificial thyroid (Armour 2g per day) to help w/moods, love life,etc. I should also mention that altho I am over weight I skate an average of 7-12 miles a day and I cannot get the weight under control(apx. 20 pounds over weight)I am working on the diet and odly enough that was the easy part.What am I doing wrong? Debbie

Debbie! I've tried to contact you via email without success. Could you write again and let me know your blood type? For now, investigate the supplement "maca," a Peruvian plant for which the root only is used to make a rather tasty powder ~ just take as suggested on the package. It is very helpful for hormone and libido issues, for both sexes. PennHerb sells a great-quality Maca ~ they're at www.pennherb.com. I'll wait on the blood type (and give me a basic rundown of your diet, too) to see if we can tweak the eating part of the plan at all. Thanks, dear!

Hi Heidi, thankyou so much for your informative column. I log on everyday to see whats new. Here in New Zealand more and more people are becoming convinced of the positive benefits of being "on the diet". I am a type O - non-secretor trying to be 100% compliant due to a myriad of long term health problems. Making great progress but don't want to mess up! My question is- when using aromatherapy oils, would using oils extracted from substances that are avoids eg cinnamon, orange, have a negative effect as they are absorbed through the skin and into the bloodstream. How about using them in a vapouriser? Thanks, Angela

That is great news about you Kiwis down there! ;-D and I am thrilled to hear you're seeing results from the O-non diet!! About the oils ~ The restrictions in the food lists apply only to ingested substances, i.e., stuff that passes through the digestive tract. Topical preparations and ambient scents don't count ~~ unless they produce noticeable symptoms like rash or breathing difficulties, lightheadedness, etc., they're fine for all types! :-) enjoy!!
