Why haven't you heard about lipoprotein(a)?

1. July 2010 William Davis (26)
Lipoprotein(a), or Lp(a), is the combined product of a low-density lipoprotein (LDL) particle joined with the liver-produced protein, apoprotein(a).

Apoprotein(a)'s characteristics are genetically-determined: If your Mom gave the gene to you, you will have the same type of apoprotein(a) as she did. You will also share her risk for heart disease and stroke.

When apoprotein(a) joins with LDL, the combined Lp(a) particle is among the most aggressive known causes for coronary and carotid plaque. If apoprotein(a) joins with a small LDL, the Lp(a) particle that results is especially aggressive. This is the pattern I see, for instance, in people who have heart attacks or have high heart scan scores in their 40s or 50s.

Lp(a) is not rare. Estimates of incidence vary from population to population. In the population I see, who often come to me because they have positive heart scan scores or existing coronary disease (in other words, a "skewed" or "selected" population), approximately 30% express substantial blood levels of Lp(a).

Then why haven't you heard about Lp(a)? If it is an aggressive, perhaps the MOST aggressive known cause for heart disease and stroke, why isn't Lp(a)featured in news reports, Oprah, or The Health Channel?

Easy: Because the treatments are nutritional and inexpensive.

The expression of Lp(a), despite being a genetically-programmed characteristic, can be modified; it can be reduced. In fact, of the five people who have reduced their coronary calcium (heart scan) score the most in the Track Your Plaque program, four have Lp(a). While sometimes difficult to gain control over, people with Lp(a) represent some of the biggest success stories in the Track Your Plaque program.

Treatments for Lp(a) include (in order of my current preference):

1) High-dose fish oil--We currently use 6000 mg EPA + DHA per day
2) Niacin
3) DHEA
4) Thyroid normalization--especially T3

Hormonal strategies beyond DHEA can exert a small Lp(a)-reducing effect: testosterone for men, estrogens (human, no horse!) for women.

In other words, there is no high-ticket pharmaceutical treatment for Lp(a). All the treatments are either nutritional, like high-dose fish oil, or low-cost generic drugs, like liothyronine (T3) or Armour thyroid.

That is the sad state of affairs in healthcare today: If there is no money to be made by the pharmaceutical industry, then there are no sexy sales representatives to promote a new drug to the gullible practicing physician. Because most education for physicians is provided by the drug industry today, no drug marketing means no awareness of this aggressive cause for heart disease and stroke called Lp(a). (When a drug manufacturer finally releases a prescription agent effective for reducing Lp(a), such as eprotirome, then you'll see TV ads, magazine stories, and TV talk show discussions about the importance of Lp(a). That's how the world works.)

Now you know better.

How to have a heart attack in 10 easy steps

29. June 2010 William Davis (48)
If you would like to plan a heart attack in your future, here are some easy-to-follow steps to get you there in just a few short months or years:


1) Follow a low-fat diet.

2) Replace fat calories with "healthy whole grains" like whole wheat bread.

3) Eat "heart healthy" foods like heart healthy yogurt and breakfast cereals from the grocery store.

4) Use cholesterol-reducing plant sterols.

5) Take a multivitamin to obtain all the "necessary" nutrients.

6) Take the advice of your doctor who declares your heart "in great shape" based on your cholesterol values.

7) Take the advice of your cardiologist who declares your heart "like that of a 30-year old" based on a stress test.

8) Take a statin drug to reduce LDL and c-reactive protein while maintaining your low-fat diet.

9) Neglect sun exposure and vitamin D restoration.

10) Limit your salt intake while not supplementing iodine.



There you have it: An easy, 10-step process to do your part to help your local hospital add on its next $40 million heart care center.

If you would instead like to prevent a heart attack in your future, then you should consider not doing any of the above.

Kick inflammation in the butt

25. June 2010 William Davis (0)
C-reactive protein, or CRP, is a protein produced by the liver in response to inflammatory signals its receives. Thus, CRP has emerged as a popular measure to gauge the underlying inflammatory status of your body. Higher CRP levels (e.g., 3.0 mg/L or greater) are associated with increased risk of heart attack and other cardiovascular events.

The drug cartel have jumped on this with the assistance of Harvard cardiologist, Dr. Paul Ridker. Most physicians now regard increased CRP as a mandate to institute statin therapy, preferably at high doses based on such studies as The JUPITER Trial, in which rosuvastatin (Crestor), 20 mg per day, reduced CRP 37%.

I see this differently. Two strategies drop CRP dramatically, nearly to zero with rare exception: Vitamin D restoration and wheat elimination. Not 37%, but something close to 100%.

Yes, I know it sounds wacky. But it works almost without fail, provided the rest of your life is conducted in reasonably healthy fashion, i.e., you don't live on Coca Cola, weigh 80 lbs over ideal weight, and smoke.

How can something so easily reduced like CRP mean you "need" medication? Easy: Increased CRP means there are fundamental deficiencies and/or inflammation provoking foods in your diet. Correct neither and there is an apparent benefit to taking a statin drug.

Why not just correct the underlying causes?

Life without Lipitor

25. June 2010 William Davis (17)
One of the most common reasons people come to my office is to correct high cholesterol values without Lipitor. (Substitute "Lipitor" with Crestor, simvastatin, Vytorin, or any of the other cholesterol drugs; it's much the same.)

In the world of conventional healthcare, in which you are instructed to follow a diet that increases risk for heart disease and not advised to correct nutrient deficiencies like vitamin D and omega-3 fatty acids, then a drug like Lipitor may indeed provide benefit.

But when you are provided genuinely effective information on diet, along with correction of nutrient deficiencies, then the "need" and apparent benefits of Lipitor largely dissolve. While there are occasional genetic anomalies that can improve with use of Lipitor and other statins, many, perhaps most, people taking these drugs really would not have to if they were just provided the right information.

Anyone following the discussions on these pages knows that wheat elimination is probably one of the most powerful overall health strategies available. Wheat elimination reduces real measured LDL quite dramatically. Provided you limit other carbohydrates, such as those from fruits, as well, LDL can drop like a stone. That's not what your doctor tells you. This approach works because elimination of wheat and limiting other carbohydrates reduces small LDL. Small LDL particles are triggered by carbohydrates, especially wheat; reducing carbohydrates reduces small LDL. Conventional LDL of the sort obtained in your doctor's office will not show this, since it is a calculated value that appears to increase with reduced carbohydrates, a misleading result.

Throw vitamin D normalization and iodine + thyroid normalization into the mix (both are exceptionally common), and you have two additional potent means to reduce (measured) LDL. Not restricting fat but increasing healthy fat intake, such as the fats in lots of raw nuts, olive oil, and flaxseed oil reduce LDL.

While I still prescribe statins now and then, a growing number of people are succeeding without them.

(Note that by "measured" LDL I am referring to the "gold standard," LDL particle number by NMR provided by Liposcience. A second best is measured Apoprotein B available through most conventional labs.)

In search of wheat: Emmer

23. June 2010 William Davis (13)
While einkorn is a 14-chromosome ancient wheat (containing the so-called "A" genome), emmer is a 28-chromosome wheat (containing the "A" and "B" genomes, the "B" likely contributed by goat grass 9000 years ago).

Both einkorn and emmer originally grew wild in the Fertile Crescent, allowing Neolithic Natufians to harvest the wild grasses with stone sickles and grind the seeds into porridge.

Having tested einkorn with only a modest rise in blood sugar but without the gastrointestinal or neurological effects I experienced with conventional whole wheat bread, I next tested bread made with emmer grain.

The emmer grain was ground just like the other two grains, cardiac dietitian Margaret Pfeiffer doing all the work of grinding and baking. Margaret added nothing but water, yeast, and a little salt. The emmer rose a little more than einkorn, but not to the degree of conventional whole wheat.

I tested my blood sugar beforehand: 89 mg/dl. I then ate 4 oz of the emmer bread. It tasted very similar to conventional whole wheat, but not as nutty as einkorn. Also not as heavy as einkorn, only slightly heavier than conventional whole wheat.

One hour later, blood sugar: 147 mg/dl. I felt slightly queasy for about 2-3 hours, but that was the end of it. No abdominal cramps, no sleep disturbance or crazy dreams, no nausea, no change in ability to concentrate.

I asked four other wheat-sensitive people to try the emmer bread. Likewise, nobody reacted negatively (though nobody tested blood sugar).

So it seems to me, based on this small, unscientific experience, that ancient einkorn (A) and emmer (AB) wheat seem to act like carbohydrates, similar to, say, rice or quinoa, but lack many of the other adverse effects induced by conventional wheat.

Modern wheat , Triticum aestivum, contains variations on the "A," "B," and "D" genomes, the "D" contributed by hybridization with Triticum tauschii at about the same time that emmer wheat hybridization occurred. It is likely that proteins coded by the "D" genome are the source of most of the problems with wheat products: immune, neurologic, gastrointestinal destruction, airway inflammation (asthma), increase in appetite, etc. This is consistent with observations made in studies that attempt to pinpoint the gliadin proteins that trigger celiac, the area in which much of this research originates.

If I ever would like an indulgence of cookies or cupcakes, I think that I will order some more einkorn grain from Eli Rogosa.

In search of wheat: Another einkorn experience

23. June 2010 William Davis (6)
Lisa is a trained dietitian. Unlike many of her colleagues, she has "seen the light" and realized that the conventional advice that most dietitians are forced to dispense through hospitals, clinics, and other facilities is just plain wrong. 

I know Lisa personally and we've had some great conversations on diet and nutritional supplements. I told Lisa about my einkorn experience and how I witnessed a dramatic difference between bread made from einkorn wheat and that made from conventional whole wheat. So she decided to give it a try herself. 

Here's Lisa's experience:


This past Friday, June 18th, I conducted my "Einkorn Wheat Experiment".

7 am 
FBG [fasting blood glucose] 97 mg/dl

8 am-9 am 
1 hour high-intensity aerobic workout

10:05 am 
BG 99

10:05 am 
I embarked upon the journey of choking down, I mean enjoying, the hefty piece of Einkorn bread. Wow, was that bread dense!  It was a lot of work chewing. 

10:50 am 
(45 minutes after consumption, wanted to see what BG did a bit before the 1 hr mark)  BG 153

11:05 am 
1hr PP 120

11:35 am 
90 mins PP [postprandial] 113

12:05 pm 
2 hours PP  114 ... at this time I ate an egg & veggie omelet for lunch.

12:50 pm 
BG 100

Before dinner 5:10 pm 
BG 88

I was surprised with the BG of 153. However, it was good to see my insulin response is reactive and decreased BG 33 points in 15 minutes to end up with a BG of 120 1 hr after the bread.  

So, it appears my response is similar. A slight elevation of BG at the 1 hour mark, but not to the degree of conventional whole grain wheat bread.  

Of note, also, was the fact that I cannot remember the last time I ate a piece of wheat bread of this magnitude that did not make me bloated... not at all: No cramps, no brain fog, no headache and, did I mention not bloated?  

I believe you are on to something with tolerance of Einkorn wheat for those of us with wheat sensitivities, in addition to its apparent lower glycemic response.

Along with Lisa, I asked four other people with various acute intolerances (all gastrointestinal) to conventional wheat, i.e., people who experience undesirable effects from wheat within minutes to several hours, to eat the einkorn bread. None experienced their usual reactions.

Obviously, this does not constitute a clinical trial. Nonetheless, I find this a compelling observation: People like myself who generally experience distinct undesirable reactions to wheat did not experience these reactions with einkorn.

Note, however, that einkorn behaves like a carbohydrate. No different, say, from brown rice or quinoa. However, unlike modern whole wheat flour from Triticum aestivum,  in this little experience there were no immune reactions, no neurologic phenomena, no gastrointestinal distress--just the blood sugar consequences.

While this may not be true for all people consuming einkorn, it suggests that primordial einkorn wheat is quite different from modern conventional wheat for most people.

Increased blood calcium and vitamin D

21. June 2010 William Davis (50)
Conventional advice tells us to supplement calcium, 1200 mg per day, to preserve bone health and reduce blood pressure.

Here's a curious observation I've now witnessed a number of times: Some people who supplement this dose of calcium while also supplementing vitamin D sufficient to increase 25-hydroxy vitamin D blood levels to 60-70 ng/ml develop abnormally high levels of blood calcium, hypercalcemia.

This makes sense when you realize that intestinal absorption of calcium doubles or quadruples when vitamin D approaches desirable levels. Full restoration of vitamin D therefore causes a large quantity of calcium to be absorbed, more than you may need. In addition, two studies from New Zealand suggest that 1200-1300 mg calcium with vitamin D per day doubles heart attack risk.

We have 20 years of clinical studies demonstrating the very small benefits of supplementing calcium to stop or slow the deterioration of bone density (osteopenia, osteoporosis). These studies were performed with no vitamin D or with trivial doses, too small to make a difference. I believe those data have been made irrelevant in the modern age in which we "normalize" vitamin D.

Should hypercalcemia develop, it is not good for you. Over long periods of time, abnormal calcium deposition can occur, leading to kidney stones, atherosclerosis, and arthritis.

Until we have clarification on this issue, I have been advising patients to take no more than 600 mg calcium supplements per day. I suspect, however, that the vast majority of us require no calcium at all, provided an overall healthy diet is followed, especially one that does not leach out bone calcium. This means no foods like those made with wheat or containing powerful acids, such as those in carbonated drinks.

Heart health consultation with Dr. Joe D. Goldstrich

20. June 2010 William Davis (3)
Cardiologist, nutritionist, and lipidologist, Dr. Joe D. Goldstrich, is a frequent contributor to the Track Your Plaque Forum, where we discuss the full range of issues relevant to coronary health and coronary plaque reversal.

I have come to value Dr. Goldstrich's unique insights, especially in nutrition. Formerly National Director of Education and Community Programs for the American Heart Association and a physician at the Pritikin Center, his dietary philosophy has evolved away from low-fat and towards a low-carbohydrate focus, much as we use in Track Your Plaque. Like TYP, Dr. Goldstrich is always searching for better answers to gain control over coronary health. His unique blend of ideas and background has helped us craft new ideas and strategies. Dr. Goldstrich has proven especially adept at understanding how to incorporate new findings from clinical studies in our framework of coronary atherosclerotic plaque management strategies.

Dr. Goldstrich is offering to share his expertise with our online community. If you would like a one-on-one phone consultation with Dr. Goldstrich, you can arrange to speak with him at his HealthyHeartConsultant.com website.

Wheat aftermath

16. June 2010 William Davis (18)
Following my 4 oz whole wheat misadventure that yielded the sky-high blood sugar of 167 mg/dl, compared to einkorn wheat's 110 mg/dl, I suffered through a 36-hour period of misery.

After I obtained the blood sugar of 167 mg/dl, I biked hard for one hour. This yielded a blood sugar back down in the 80s. I felt spacey in the ensuing few hours, as well as a little queasy. However, about 12 hours later, I awoke with overwhelming nausea along with that hypersalivating thing that happens just prior to vomiting. It did not come to that, but persisted all through the following day.

The next morning, I could barely concentrate. Trying to read a study (admittedly on the complex topic of agricultural genetics), I had to read each paragraph 4 or 5 times. Abdominal cramps and a bloated feeling also developed, though I was able to eat.

The 2nd night was filled with incredibly vivid dreams and intermittent sleeplessless. I awoke about 5 times through the night, but periods of sleep were filled with detailed, colorful dreams. I dreamt that a large corporation was secretly trying to gain control over the world's water supply, and I snuck onto a complex underwater vessel that was exploring and mapping the coastline of the Great Lakes in preparation. Weird.

I recognized these odd feelings as various facets of wheat intolerance, since they were all reminiscent of feelings I used to experience before I removed wheat from my diet. They were amplified and compressed, likely because I had been wheat-free for so long.

The odd thing is that, despite the modest blood sugar effect of my einkorn experience, none of the gastrointestinal or neurologic effects of wheat developed. So far, two other people with acute gastrointestinal wheat sensitivities have consumed our einkorn bread, also without reproduction of their usual symptoms.

Einkorn contains gluten, though the structure of the many gluten proteins of einkorn differs from that of the wheat bread I consumed, an example of modern Triticum aestivum. 14-chromosome einkorn carries what biologists call the "A" genome, while Triticum aestivum has the combines genomes of 3 plants, the combination of the A, B, and D genomes. It is the D genome that contains the genes coding for the most obnoxious, immunogenic forms of gluten.

So einkorn may not be entirely benign, but it is a good deal less obnoxious than modern Triticum aestivum.

I am awaiting the reports from a few other people on their experiences.

In search of wheat: Einkorn and blood sugar

14. June 2010 William Davis (32)
There are three basic aspects of wheat's adverse health effects: immune activation (e.g., celiac disease), neurologic implications (e.g., schizophrenia and ADHD), and blood sugar effects.

Among the questions I'd like answered is whether ancient wheat, such as the einkorn grain I obtained from Eli Rogosa, triggers blood sugar like modern wheat.

So I conducted a simple experiment on myself. On an empty stomach, I ate 4 oz of einkorn bread. On another occasion I ate 4 oz of bread that dietitian, Margaret Pfeiffer, made with whole wheat flour bought at the grocery store. Both flours were finely ground and nothing was added beyond water, yeast, olive oil, and a touch of salt.

Here's what happened:

Einkorn wheat bread:

Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 110 mg/dl

Conventional wheat bread
Blood sugar pre: 84 mg/dl
Blood sugar 1-hour post: 167 mg/dl

The difference shocked me. I expected a difference between the two, but not that much.

After the conventional wheat, I also felt weird: a little queasy, some acid in the back of my throat, a little spacey. I biked for an hour solid to reduce my blood sugar back to its starting level.

I'm awaiting the experiences of others, but I'm tantalized by the possibility that, while einkorn is still a source of carbohydrates, perhaps it is one of an entirely different variety than modern Triticum aestivum wheat. The striking difference in blood sugar effects make me wonder if einkorn eaten in small quantities can keep us below the Advanced Glycation End-Product threshold.
 
Dangerous mis-information on vitamin D

Dangerous mis-information on vitamin D

16. January 2009 William Davis (12)

Please be aware of the ignorant propagating information they have no business talking about.

This is one such example, a newsletter from pop exercise guru, Denise Austin.

Although I'm sure she means well, I have a problem with people who have little to no experience acting as experts, often simply repeating something they heard or read somewhere else. This has become particular problem with the internet, in which bad information can get repeated thousands of times, gaining a veil of "truth" through its repetition. I don't mean to pick specifically on Ms. Austin, since she joins a growing rank of pseudo-experts on vitamin D and other topics, but she provides a good example of how far wrong mainstream information can be.



Simple Steps
Do Your D!

Calcium often gets all the glory when it comes to bone health. But calcium wouldn't benefit your bones much without its partner, vitamin D!

Why? Vitamin D helps your body absorb calcium and keeps your bones strong; without enough vitamin D, the bones become weak and brittle, a condition called rickets in children, and osteomalacia in adults. Adults from 19 to 50 need 200 IU (international units) per day, while those from 51 to 70 need 400 IU daily. Those over 70 need 600 IU per day.

Unfortunately, not too many foods contain vitamin D naturally. (Tuna and sardines canned in oil are exceptions.) The good news is that many foods are now regularly fortified with vitamin D, including milk, some yogurts, margarines, and cereals. You can check the Nutrition Facts panel on packages and containers to see which products contain vitamin D. It should be listed after vitamins A and C, along with the percentage of the Daily Value that a serving of the food contains. The Daily Value (a standardized amount) for vitamin D is 400 IU, so if your milk has 25 percent of the Daily Value, it provides 100 IU per serving.

Your skin can also make vitamin D using sunlight — you need about a half hour of exposure to the midday sun twice a week to make enough. However, because of the increasing incidence of skin cancer in recent years, many experts are wary about recommending sun exposure.

So take a closer look at milk, yogurt, cereal, and margarine selections when you're doing your weekly shopping, and stock up on brands that are fortified with vitamin D. Challenge yourself to consume one source of vitamin D at least three days in the coming week! If you cannot eat or do not like any foods that contain vitamin D or are fortified with it, talk with your health care provider ASAP about taking a supplement. Your bones will thank you for it!



Let me list the mistakes in this piece:

Adults from 19 to 50 need 200 IU (international units) per day, while those from 51 to 70 need 400 IU daily. Those over 70 need 600 IU per day.

This is the same non-information that was the advice originally offered by the Food and Nutrition Board based on a best guesstimate due to lack of data. It is clear from newer data that doses required for full restoration of vitamin D are in the thousands of units. (My personal dose for full restoration of vitamin judged by serum levels of 25-hydroxy vitamin D is 8000 units per day.)

The information coming from the Food and Nutrition Board is about as good as the information coming from the USDA (you know, that "government" agency meant to represent the interests of ConAgra, Cargill, and Big Farming) and the American Heart Association (that represents consensus opinion from data 20 years out of date and now arm-in-arm with Big Food like General Mills, Kraft, and Nabisco). These agencies and the advice they offer has, over the past few years, become increasingly irrelevant and outdated. It is the Information Age, in which ulterior motives are becoming more readily exposed, yet they still operate by the rules of the Industrial Age and deliver a message that serves their own purposes.

Ms. Austin fell for it.


The good news is that many foods are now regularly fortified with vitamin D, including milk, some yogurts, margarines, and cereals.

First of all, what is a "diet expert" doing advocating industrial foods? Cereals, in particular, are among the worst foods on the supermarket shelves, whether or not they are fortified. Candy bars can be fortified, too; that doesn't make them any better for you.

The vitamin D added to these foods is, more often than not, the ergocalcferol, or D2, form that is woefully ineffective. And the dose added is trivial, usually in the 100-200 unit range per serving. The same goes for the milk, an inadequate source that we don't even factor into total intakes because of the low quantity.


Your skin can also make vitamin D using sunlight — you need about a half hour of exposure to the midday sun twice a week.

Nope. This might be true for a young person below age 30 in a southern environment. It is NOT true for the majority of people in northern climates and anyone over age 30 or 40, since we lose most of the capacity to activate vitamin D in the skin as we age. A deep, dark Florida tan does not necessarily mean that vitamin D has been activated. See A tan does not equal vitamin D. Here in Wisconsin, where, despite this darn cold winter, does enjoy wonderfully warm and beautiful summers, the average vitamin D dose need ranges from 4000-8000 units per day in summer, slightly more in winter.

By the way, it is not calcium that is instrumental to bone health. It is vitamin D. Calcium is the passive bricks and mortar of bones, while vitamin D is the bricklayer, the determinant of calcium's fate, the master control of bone health. Calcium supplementation becomes almost immaterial when vitamin D is restored.

I praise Ms. Austin for her hard work, trying to help fat Americans lose weight. But please ignore her advice on vitamin D, along with the numbing repetition of this mis-information that will likely propagate from other exercise gurus, dietitians, and pseudoexperts.

    Thanks for posting this and continuing your efforts to provide the public with GOOD information about D and health in general.

    Most doctors don't "get it" when it comes to Vit D, so I don't expect Ms. Austin too either.

    I'll stick with www.vitamindcouncil.com, my own research, and your site. Thats my vitamin D package.

    P.S. A local pharmacy began carrying the 5,000 D-3 capsules! And, one of our patients is a pharmacist for a national chain and during a visit last week, we asked about the possibility of his pharmacy carrying 5,000 IU D3 and he said, "not a problem!"

    My gynecologist has got it wrong, too.  When I told her I was taking 3000IU of vit. D per day she snorted and said, "I think you mean 300".  I said, "No, 3000" and I explained that I had been deficient.  She said "There's just too much hype about D these days."

    If you still think the vitamin D gelcaps work and the tablets don't, why don't you mention it more often: a lot of people take the tablets because they're cheaper, thinking they're getting the benefit.

    For Cristy
    http://www.vitamindcouncil.org/newsletter/2008-october.shtml
    Dr Cannell talks about the idea amount for children here.

    For anonymous. Vitamin D3 is made from the cholesterol in our skin. As we age our skin gets thinner and their is less cholesterol near the surface for the UVB rays to turn to  vitamin D3. You may find Dr Davis's previous blog on the topic interesting.
    http://heartscanblog.blogspot.com/2008/07/vitamin-d-and-programmed-aging.html

    Re  Peter Silverman some of us, who regularly get our 25(OH)D tested, use dry powder Vitamin D3 5000iu capsules do find, if we consume them with food, that we can attain and maintain a reasonable 25(OH)D status using these cheaper capsules.
    Dr Davis finds the oil gel generally more reliable and so you pays your money and takes your choice. but vitamin d3, whatever form can be found very cheaply so cost/saving should not be the first priority.

    But all skinflints here may be interested in the GRASSROOTS VITAMIN D TESTING TRIAL.
    http://www.grassrootshealth.net/d-action
    Sign up now for a 25(OH)D test from zrt labs for just $30 every six months for the next 5 years.
    These tests normally cost $75 and the vitamin D council were doing them for $ 65.00
    So hopefully those who save money will think about a donation to support the Grassroots site

    Ted, thanks for the grassroots Vit D info.  Turns out the administration of this study/PR campaign is right in my own backyard (metaphorically speaking).  I'm going to help the administrator stuff test kit envelopes (saving them $1000s in mail  stuffing services) and get the word out in the local vitamin stores and "health food" stores, etc.

    Even though my family can get our levels tested through our HMO network, covered by insurance, I signed up the entire family for this study, because I feel strongly about helping them to get the data they need about Vit D levels and health conditions.

    Cristy, I started my 75 pound 10 yo old on 3000 iU of Vit D3 (Carlson brand) when the school year started (more indoor time), based on the Vit D Council's weight/dose recommendations.  We had a need to get a blood sample for something else in December and I requested a 25 (OH)D at the same time.  It was 72 ng/ml, perfect!  I'll probably reduce or stop the Vit for the summer months, though, as he's outdoors a lot.  

    BTW, we are in coastal San Diego County, where nearly all the middle aged (or older) adults I know who get tested are in the very low reference range (30s) or lower (my husband and I test so far in the 40s with some D3 supplementation, so we raised our dose in line with the Vit D Council's recs, too).  

    So sunny mild climate means little if one's indoor or sun-avoidance lifestyle has little sun exposure (or age).

    It is such hell trying to work without the help of a nutritional doctor.

    The vitamin D added to these foods is, more often than not, the ergocalcferol, or D2, form that is woefully ineffective. And the dose added is trivial, usually in the 100-200 unit range per serving. The same goes for the milk, an inadequate source that we don't even factor into total intakes because of the low quantity.
