Errata and Clarifications

With a work of this size and depth, it is perhaps inevitable that a few confusions and typographic or editorial omissions will occur.  As they are identified, they will be addressed here.

A NOTE ON CERTAIN VALUE CHANGES

A small number of foods have had value changes since ER4YT. 

Virtually all of the changes are lectin-related (leeks, pinto beans, sunflower products for type O, changes to certain mushrooms for type A and AB, for example).  Many of these newer values are the result of determinations which are way beyond the level of sophistication that I was using back in the 1980's.  In particular, the molecular biology of lectins and cancer cells is still beyond my current capabilities, so we must rely on the literature for that research.  Many dietary lectins can have a mixed function; some effects good, other effects bad.  Sometimes we learn of one before the other.  Pinto beans, leeks and mushrooms are good examples of lectin containing foods with sophisticated and mixed biological effects.  Because knowledge of these relationships continues to expand (for example, the link between polyamine production and lectins was not understood well at the time of ER4YT) some begin to look better (mushrooms) while others begin to look worse (pinto beans).  The added criteria of nonsecretor reaction have generated a yet higher level of refinement in the food value arena.

UNLISTED FOODS

Can be considered NEUTRAL.

UNDERSTANDING THE TWO-TIER SYSTEM

Tier One is the basis of the diet for everyone.  

If you simply wish to maintain and enhance your current level of health, use Tier One as your staple foods, and choose freely from Tier Two and the Neutral Tier for added variety.  In this case, the "avoid" foods listed in Tier Two can be considered "neutral."

Tier Two values should be used as written if you are seeking to resolve an illness, heal from injury, lose weight, bear up under added stress, or to alleviate chronic fatigue or other health issues -- or if you are following the diet according to your status as one of the variants MM or A2.  Minimize your use of Neutral Tier foods.  This is the "turbo" version of the diet, designed to speed healing and provide added protection against disease.

·         Jam/Jelly (OK Ingredients) is Neutral for all. 

·         Rice Vinegar follows the values for Vinegar (Balsamic/white/ red) for all blood types.

·         On the second page of acknowledgements, the company's name should read "The Republic of Tea."

·         On p. 265 of the type B diet, the lines "Onions are also a powerful friend to Type B. They contain significant amounts of the antioxidant quercetin, a powerful antimutagen," and "Artichoke is quite beneficial to the liver and gallbladder, weak spots for Type B."  were mistakenly transcribed from type A diet.  Onions are generally Neutral for type B secretors, and Beneficial for type B nonsecretors.  Artichokes are a B-secretor Avoid and a B nonsecretor Neutral.

·         Broad Bean and Fava Bean have also been consolidated, as they are identical in common parlance.  The new listing is Fava (Broad) Bean, and its values are Beneficial for A secretors; Avoid for AB secretors and O nonsecretors; and Neutral for all others.

·         Green/Snap/String Bean is a consolidation of the separate items appearing in LR, and has the values Tier I Beneficial for all As, Neutral for all other types.  The separate values listed in LR4yT should be disregarded in favor of this combined value.

·         Under FRUITS, the serving frequency should read "per day" rather than "per week" for all types.

·         For type AB, on page 317, Blackberry/blackberry juice is listed as Beneficial  for AB secretors and Neutral for AB nonsecretors. This is backwards; it is NEUTRAL  for AB secretors, BENEFICIAL for AB nonsecretors.

·         Ezekiel Bread is upgraded to Tier I Beneficial for A and B secretors and AB nonsecretors.  

·         Oat/Oat Bran/Oatmeal is listed as Neutral for type A secretors; its status is Tier I Beneficial.

·         On p. 271 it says "Walnut oil and black currant seed oil are highly beneficial for type B secretors."  This should read "type B nonsecretors."

·         The values for Mustard (Prepared) have been refined for all types based upon four possible preparations:  with wheat and vinegar; with wheat, vinegar-free; wheat-free with vinegar; wheat- and vinegar-free.

·         In the type B diet, Salad Dressing should read "Salad Dressing/OK Ingredients" and the item Tamari should read "Tamari (Wheat-free)."

·         Worcestershire Sauce is changed to Avoid for type O secretors.

·         The value of Mustard, Dry in the type A Herb/Spice list has been upgraded to Beneficial for secretors and nonsecretors.  

·         Yeast (Brewers) includes Nutritional Yeast.  Its values are changed from Neutral to Beneficial for type AB nonsecretors.

·         The type A listing for Tea (Black Regular) should read Tea (Black Regular/Decaf). 

Deletions:

Several items have been removed from the food list:

·         Lox and Herring/Kippers.  These foods may or may not be smoked; and may include varying spices, vinegar, etc. which should be evaluated individually.  The item Herring remains, indicating the fresh fish, as does Salmon. 

·         Mollusks, Mint and Malt, due to redundancy.  Several types of mollusks and mints, as well as Barley Malt (to which "Malt" refers) are valued separately.

·         Red Bean, as it is a term commonly applied to several different kinds of beans.  

We are in the process of revamping the TYPEbase®, a searchable food value database by blood group, to display all updated values on all foods tested.  While further amendments will be few, this Errata and Clarifications Page will serve as our change log, showing any additions or modifications made relative to the food lists in Live Right 4 Your Type.
