Invert Sugar values
are Neutral for type A secretors, and Tier I Avoid for all other
types.
Avocado
Oil: is Neutral for type A. Note: since avocado can be
problematic for the other blood groups, they should consider this item
a Tier I Avoid, no different from avocado. Until further elaboration,
this Avoid status should be observed by group O nonsecretors as well.
Lecithin
is not given a specific value in LR4YT. It is Neutral for
all types. For type Bs, egg lecithin is slightly preferred over
soy lecithin, but either is OK.
