Monitoring pH to encourage bone regrowthI am grateful to have found this newsgroup, with its high level discourse
and its unselfish sharing of quality information. It has been a great help
to me for the past 10 months.
What follows is an extensive case history, my treatment regimen, and a
request for your advice.
DIAGNOSIS
I am male, 68 years old, of Scandinavian descent, 6'3" tall (1.9 meters),
151 pounds (68 kg). BMI = 18.9. I live in northern California.
I am active for my age. My routine includes fifteen minutes of bends,
stretches and calisthenics in the morning. Before retiring in May 2007, I
used to walk 2 miles at lunchtime most days, and on the weekends I either
worked on our 40 acres or hiked the trails up into the hills behind the
house, easily climbing 400 ft in elevation or more.
As a retiree, I continue to get outside daily, lately making new trails.
With warmer weather, I will be clearing brush, cutting firewood, and doing
other chores in place of some of the hiking.
I had been found to be low on testosterone in 2006. This was certainly
showing up in libido, and I had been wondering if it would show up in my
skeleton as well. So in March 2007 I had a baseline DEXA scan, which showed
that I have severe osteoporosis of the spine and osteopenia of the femurs:
Spine: T-Score -4.1; Z-Score -3.5
Dual Femur (mean): T-Score -2.4; Z-Score -1.7.)
The diagnosis blindsided me. I had been getting in firewood for weeks, and
had just processed a 100-foot tall, 3 foot diameter Douglas fir. I'd been
chain-sawing the log on an awkward hillside, banging away on steel wedges
with my 12-pound maul to split the rounds down, wheel-barrowing 35 loads 250
ft to my woodshed, cutting and burning the slash. How could I have done all
that with fragile bones?
RESPONSE TO DIAGNOSIS
I became an osteoporotic cripple for a couple of weeks, until I decided that
perhaps my bones weren't about to crack, in spite of the diagnosis. Since
then I have carried on as usual, except that I am careful to hold the
railing when going down stairs. We haven't gone skiing yet this winter, and
I am not decided whether I want to. (Besides, we now have grandkids to
visit on the weekends.)
On a follow-up visit, my doc prescribed Fosamax and told me to eat cheese
and drink milk. By then I had done some research. I asked him about the
acidifying properties of milk and cheese. He was unaware of any connection.
I decided to ignore his dietary recommendations. Averse to medications and
unwilling to risk osteonecrosis, I also decided to forego the medication.
Instead, I gave myself one year to try to begin rebuilding bone by other
means.
I found a nutritionist nearby who claimed to have experience with people
with osteoporosis. She too appeared ignorant of acid/alkaline foods, and
ended up giving me her standard fact sheet with the same dietary
recommendations she gives to all her clients, except that she crossed off
the 60 gm of protein daily and said I should eat yogurt and cheese and get
75 gm of protein a day. I decided to ignore her recommendations as well.
I should say that my wife and I are very health conscious, and eat organic
food almost entirely. But these professionals just did not seem to be well
informed on osteoporosis.
I am trained as a chemist, and understand perfectly how the body would pull
calcium out of bones if it were needed to buffer the internal environment.
I decided to study the lists of acidifying and alkalinizing foods on the
Web, and modify my diet accordingly. I would also put an increased emphasis
on weight bearing exercise.
I studied labels on my multivitamin, and found that the tablets that I had
taken for years (Centrum Silver) contained only 400 IU of Vitamin D
(cholecalciferol). I have had a couple of skin cancers removed, so have
been very careful to avoid direct sunlight, thus losing the Vitamin D that I
might have received while outdoors. I am now supplementing with an
additional 800 IU of Vitamin D.
Each tablet also contains 200 mg of calcium. I now supplement this with an
additional 1000 mg, as calcium carbonate.
The tablet contains 100 mg of magnesium. The combined D-Ca-Mg supplement
contains 500 mg of magnesium. I split the calcium/magnesium/Vitamin D pill
and take halves in the morning and evening. I take the multivitamin at
midday.
I believe that insufficient Vitamin D was a major part of the cause of my
osteoporosis. I was getting 1/3 or 1/2 cup of dried organic milk daily, but
it was non-fat. I don't know if it contained Vitamin D or not, since it
lacked the fat to carry it.
DIET
I also saw an orthopedist who had once treated me for a wrist problem. He
mentioned the undesirability of relying on milk and cheese for the treatment
of osteoporosis, stating that the acidity produced by the protein would work
against the calcium. He pointed me to the work of Dr. John McDougall.
My wife and I had read McDougall's books years ago. He had thrown off his
standard medical thinking after working with Asian farmers on remote
Hawaiian farms. He attributed their remarkable health to their diets of
vegetables and grains. This was during our vegetarian years, and I found
that we were already eating in his style, except that I did take dairy foods
and, on occasion, meat/fish/fowl.
I studied Dr. McDougall's web site ( http :// www .drmcdougall,com ), including
the archived copies of his newsletter. He maintains that the American diet
contains far too much protein. He said that protein malnutrition is
extremely rare in the U.S., and that, in fact, it is hard for vegetarians to
get insufficient protein.
He recommends a vegan diet with 15 grams of protein a day. I studied the
labels and found that two small slices of whole grain bread and two
tablespoons of almond butter contained 14 gm protein between them. At that
point I stopped worrying about getting enough protein on a vegan diet. I
dropped meat and dairy, thereby becoming a vegan. (I'm not doctrinaire; I
do partake of flesh when away from home, though rarely. I will have pizza
in spite of the cheese, if that's what is served.)
I want to be sure to get all of the essential amino acids. My solution is
to get complimentary protein, by eating some grains and some mung bean
sprouts every day.
MONITORING pH
I began to notice that various lists of acidifying and alkalinizing foods
didn't agree with one another. The last straw was when I read Vasey's "The
Acid Alkaline Diet". He states that millet is very acidifying, whereas the
information on the Web all indicated that millet was the only grain that was
not acidifying.
I decided to keep a complete food log, with the times of eating each meal,
and to monitor my urinary pH with three readings a day: morning, afternoon
and evening. This would allow me to see the effects of various foods, and
thus to avoid those that would work against me.
I ordered several months' supply of "pH Stix" from pH Ion Nutrition
(www .pH-ion,com ). They come in little packets of 80 little plastic strips
with two colored panels at the tip that react to acidity.
I find the system very easy to use. You simply dip the tip of the stick
into a sample of urine and compare the resulting colors to a reference chart
to read the pH.
As you probably know, a neutral environment has a pH of 7.0. The
recommended range for rebuilding bone is from slightly acid (6.75) to
slightly alkaline (7.25). Over the past six months, my morning, afternoon
and evening readings (as recorded in a spreadsheet) have averaged 7.0, 7.0
and 6.9, respectively.
pH VS. FOOD INTAKE
My food logs now go back more than six months, and I would like to share
what I have learned.
I have concluded, first, that Vasey was wrong. Millet is absolutely not
"very acidifying". I eat half a cup of either millet, quinoa, or amaranth
every morning, and stay nicely neutral on any of them.
Second, protein is what I call an "acid bomb." I can see this clearly in my
data. As a chemist, I attribute that to its nitrogen content. There has to
be some reason why some foods are more acidifying than others, and this is
the best explanation that I have been able to come up with.
Third, the protein bomb "detonates" with a delayed reaction, anywhere from
18 to 36 hours. It took me months to pinpoint this effect, and now the
readings make much more sense.
For example, after a Sunday dinner of Chinese food with chicken, the Monday's
readings may look nicely neutral, but the acidity will show up on Tuesday,
and linger for awhile.
With this insight, I have even started predicting when the acidity will kick
in.
MENU
(Fast forward through this section if you're not interested in dietary
details.)
Typical breakfast:
1/2 cup grain (millet, quinoa or amaranth), cooked in the microwave
1 Tbsp raisins
1 Tbsp canola oil (just to keep from losing weight)
2 tbsp flaxseeds, freshly ground
1 tbsp wheat germ
2 tbsp sunflower seeds
1 tbsp pumpkin seeds
Optional: fruit (1 cup seedless grapes, 1/2 diced apple)
Typical lunch/dinner (briefly pressure cooked; good for four or five meals):
1 winter squash with the rind cut off, cut in chunks
3 tablespoons of oat grains (look like rice or barley)
2/3 bunch Dino kale, cut up
1 large zucchini cut in disks
1/3 head cabbage, chopped
4 ribs celery, chopped
2-1/2 medium yellow onions, cut in disks and separated into rings
1 small head cauliflower, cut into florets
1 medium carrot, cut in strips
10 smallish yellow potatoes, with skins
1 medium sweet potato, with skin
1/2 cup of extra virgin organic olive oil
1/2 cup mung beans, sprouted
Typical fruit salad:
2 oranges
2 apples
3 bananas
1/2 can crushed pineapple (20 oz can)
3 Tbsp raisins
2 medium carrots, grated
3 ribs celery, grated
Daily snack, at intervals, whenever
(Cut up and kept at the ready)
4 carrots
3 ribs celery
1 rutabaga
1/2 apple
Misc. as desired
Brazil nuts or almonds, raw
Green salad
1/2 cup popping corn (not acidifying!), 1 Tbsp coconut oil
These foods are all nicely neutral as to pH. I can happily eat the same
things day after day. This makes it possible to eat some of a suspected
acidifying food and watch for its effects.
To be honest, I have not spent as much time analyzing the results as I might
have. Right now I suspect that wheat bread is quite acidifying, and I avoid
it; the only wheat I get on a regular basis is the daily wheat germ in the
breakfast.
QUESTIONS
If any of you have read this far, thank you. Could you share your expertise
with me?
--I have not seen any mention of the pH monitoring approach in the last
nine months of postings. Is anybody else trying to rebuild bone by
maintaining the optimal acidity of the body? Any luck?
--I just learned that my Vitamin D 25 OH reading was 28 ng/mL (yes, mL),
and optimum is 35 ng/mL. Yet I am taking 3x the RDA. How would you
recommend that I increase that, and would there be a danger of taking too
much Vitamin D?
--I go in for my next DEXA scan in March. Would you care to hazard a
prediction of how it will go, based on what I have written here? I'll let
the group know when the results come in.
CONCLUSION
I am surprised that it is so difficult to know how best to adjust diet and
vitamins for optimal bone health, taking into account one's particular risk
factors (testosterone, age, weight, ancestry, latitude).
I am very grateful for this group. Thank you all.
