Acidic and Alkaline Food List
below categorizes a food as either acidic or alkaline based on the
effect consumption of the food has on urine pH. For
example, if a food tends to increase the acidity of urine after it
is ingested, it is classified as an acid forming food. Conversely,
if a food increases the alkalinity of urine after it has been ingested,
it is classified it as an alkaline forming food. The effect foods
have on urine pH may be quite different than the pH of the foods themselves.
For example, orange juice is a highly acidic food due to its high
citrus acid content, but after being metabolized it will cause urine
to become alkaline.
Most of the information
below is based on information from my large collection of nutrition books,
including a chart from a Mayo Clinic diet manual, and also
from personal observations. The books I have sometimes vary significantly
in how they categorize the pH of different foods, so it can be hard to
tell which ones are correct. With this in mind, take the chart
below as a general guide that most likely will contain some errors.
status can be impacted by the acid-base balance in the body. Researchers
in Germany found that "acid-base status affects renal magnesium
losses, irrespectively of magnesium intake." This means that,
besides not eating enough foods high in magnesium, acid load in the
body could be another factor that contributes to a magnesium deficiency

from people saying distilled water is not acidic or that it is very healthy
for you to drink. According to the Environmental Protection web site,
"Pure distilled water would have tested neutral, but pure distilled
water is not easily obtained because carbon dioxide in the air around
us mixes, or dissolves, in the water, making it somewhat acidic. The pH of distilled water is between 5.6 and 7." The pH of distilled
water I have bought from stores and tested myself at home has always tested
out to be acidic.
Very Acidic Foods and Supplements Include
other organ meats
from bones or other animal parts
with active cultures
including buttermilk pancakes and biscuits
- Most fermented foods and
vitamin supplements (or foods supplemented with B vitamins) can make
your stomach more acid
Please note that fermented
foods like yogurt, buttermilk and sour cream seem to become more acidic
in the body if they contain some
types of active cultures of helpful bacteria.
Food Substances That Can Make Urine Acidic
- These are supplements that contain "helpful
bacteria". At least some types of beneficial bacteria help
to create an acidic environment in the digestive tract. Probiotics
are often used after taking antibiotics and may help some cases of
bladder infections, irritable bowel syndrome and diarrhea. My friends
and family have noticed that if we take excess amounts of probiotics
it may cause heart burn and/or high blood pressure. (See my related
section on diet treatment for irritable bowel
water - Soft water is water that is low in minerals. This type
of water tends to be more acidic.
- Most fruits, except as
- Most vegetables, except
as noted above
that some foods, such as citrus fruits, have an acid pH before they
are consumed and but can leave an alkaline residue in the body
after they have been metabolized. Sorry to spell this out twice,
but I get a lot of emails on this topic.
Food Substances That Can Make Urine Alkaline
- antibiotics destroy both the bad and the helpful bacteria in the
intestinal tract. Some of the helpful bacteria work to create an acidic
environment in the human body. When these bacteria are eliminated
by antibiotics, urine may become more alkaline. I think this is one
reason why women will frequently get bladder infections after taking
I have some old nutrition text books, and in the era before wide spread
antibiotic use, health care professionals often advised people suffering
from urinary tract infections to eat a lot of meat and other acid
forming foods. Many allopathic doctors of today think acid-base balance
is a lot of malarkey, but thirty years ago you could actually find
this type of knowledge in some college nutrition text books.
mineral supplements - especially calcium, potassium, iron and
magnesium. Calcium and magnesium are common ingredients in antacids
as they neutralize stomach acid. Some people get upset stomachs (gas,
bloating, diarrhea, malabsorption) from these types of mineral supplements,
especially if they suffer from hypochloridia (low stomach acid).
- Antacids, which often contain magnesium or calcium supplements,
may cause an increase in the alkalinity of the urine, which can lead
to bladder infections as bacteria tend to thrive in alkaline environments.
Water - Hard water is just the opposite of soft water. It is water
that has a high
mineral content, and as a result tends to be more alkaline. Some
studies have shown that people have less heart attacks where the water
is hard, presumably because the disolved minerals that make the water
hard are important for nutrition.
Clinic Diet Manual, Seventh Edition categorizes the following foods
as neutral foods:
- Plain candies
Many other books on pH balance
have conflicting information to the neutral foods listed above. Most alternative
health books I own state that coffee, tea, sugar (and anything with sugar),
and corn make the urine more acid.
