are acid foods? As noted in my section on alkaline
diets, almost every book I have with information
on acid and alkaline foods has somewhat conflicting
information on this subject. In general, most
meats, grains, cheeses, nuts and legumes produce
an acid ash after they are metabolized.
following foods are generally listed as having
an acid ash:
meat including bacon, beef, cottage cheese, cheddar
cheese, chicken, eggs, fish, ham, lamb, pork and
/ Peanuts (which are really a legume)
nuts, peanuts, peanut butter, and English walnuts.
(white, rye, whole wheat), cake, white rice, refined
flour, oatmeal, shredded wheat, puffed rice, cornflakes
and macaroni have an acid ash.
cheese and cheddar cheese
fruits and vegetables are alkaline except as noted
to the authors of the Mayo Clinic Diet
Manual (MCDM), cranberries, plums and prunes
have an acid ash. This is due to their benzoic
and quinic acid content that are excreted in the
urine as hippuric acid. Elson Haas, writing in
Staying Healthy with Nutrition notes that
pomegranates and strawberries have an acid ash.
to the authors of Nutrition Almanac, asparagus
and brussel sprouts have an acid ash. The MCDM
lists corn as having an acid ash. All other vegetables
are shown as listed form all my other books as
having an alkaline ash.
