Nutrients Are Needed to Heal Wounds and Injuries

Posted by on October 7, 2010 68 comments

Abby asked for suggestions to accelerate healing of her injuries. What should be done when a wound won’t heal?

More often than not, I think, slow healing wounds reflect nutritional deficiencies. Tissue regeneration is a nutrient-intensive process, and a lack of nutrients can radically slow it down.

Osteoporosis Epidemic Indicates a Widespread Deficiency of Bone Nutrients

Tissues are not static:  they are constantly broken down and regenerated. So just maintaining tissues requires a steady supply of nutrients.

Bone is particularly in need of certain nutrients: vitamins C, D, and K2; magnesium; and others. Unfortunately, the nutrients needed by bone are precisely the ones in which Americans are most deficient.

I believe that deficiencies in these nutrients are the main cause of the osteoporosis epidemic. Take vitamin K2. Most Americans are deficient in vitamin K2, which is needed for bone calcification. Non-vertebral fractures are five-fold more common in people with vitamin K2 deficiency. [1] The rise in fracture rate in women after menopause may be due to the fact that estrogen improves vitamin K2 status. [2]

Vitamin D is another nutrient critical for bone health. Bone mineral density peaks in the range 32 to 45 ng/ml. [3]

Vitamin C is a third nutrient necessary for bone health. Vitamin C is needed for collagen to form a meshwork that can then be mineralized by calcium, magnesium and other minerals. In the absence of vitamin C, bone is malformed.

Interestingly, cow’s milk has only one-fifth the vitamin C of human breast milk, and vitamin C is destroyed during pasteurization, so formula-fed babies before the days of vitamin C supplementation were prone to scurvy. Some believe that vitamin C and vitamin D deficiencies, not malicious parents, are responsible for “Shaken Baby Syndrome.” [4,5]

Vitamin Levels Determine the Success of Orthopedic Surgery

Today I read a press release about a study that found that 40% of all patients arriving for orthopedic surgery, and 52% of those coming in for trauma service, were deficient in vitamin D. Deficiency was defined as 25(OH)D levels below 20 ng/ml.

(We recommend keeping 25(OH)D between 35 and 50 ng/ml.)

What happened?  Those who had surgery with vitamin D deficiency failed to heal properly, while those who were vitamin D sufficient generally did well. Concluded the doctors:

“In the perfect world, test levels, fix and then operate,” said Joseph Lane, M.D., professor of Orthopedic Surgery and chief of the Metabolic Bone Disease Service at HSS, who led the study. “If you put people on 2,000-4,000 [milligrams] of vitamin D based on what their deficient value was, you can usually get them corrected in four to six weeks, which is when you are really going to need the vitamin D. If you are really aggressive right before surgery, you can correct deficient levels quickly, but you have to correct it, measure it, and then act on it.”

According to Dr. Lane, bone remodeling or bone tissue formation, a part of the healing process, occurs about two to four weeks after surgery. This is the critical stage when your body needs vitamin D….

“With arthroplasty, there is a certain number of patients that when you put in the prothesis, it breaks the bone adjacent to the protheses, which can really debilitate patients.” This could be prevented or minimized by rectifying vitamin D levels. Dr. Lane also explained that they now perform procedures where they grow a bone into a prosthesis without using cement. “In those people, it would be an advantage to have adequate vitamin D, because it matures the bone as it grows in, it is really healing into the prosthesis,” he said.

“The take home message is that low vitamin D has an implication in terms of muscle and fracture healing, it occurs in about 50 percent of people coming in for orthopedic surgery, and it is eminently correctable,” Dr. Lane said. “We recommend that people undergoing a procedure that involves the bone or the muscle should correct their vitamin D if they want to have an earlier faster, better, result. What we are saying is ‘wake up guys, smell the coffee; half of your patients have a problem, measure it, and if they are low, then fix it.'” [6]

Conclusion

If you have any sort of injury, make sure you are well nourished.

If an injury refuses to heal, consider it a red flag:  you are probably missing one or more crucial micronutrients. Take steps to identify the deficiencies and remedy them as quickly as possible.

Fighting Viral Infections by Vitamin C at Bowel Tolerance

Posted by on September 26, 2010 134 comments

Alan Smith’s remarkable recovery from a seemingly fatal infection, discussed here and here, thanks to administration of 100 g/day vitamin C over vigorous opposition from his doctors, highlights both the slow pace of medical progress and the potential benefits of natural healing methods that cooperate with human biology.

The doctors’ adamant opposition to vitamin C treatment is hard to fathom. There is ample clinical experience demonstrating that high doses of vitamin C can help the body defeat viral infections. Moreover, it is among the safest of known interventions.

Vitamin C in Animals

Vitamin C apparently first developed in plants and land animals about 500 million years ago. An ability to synthesize vitamin C has been retained by most land animals and birds. [1]

Over 4,000 species of mammals can synthesize vitamin C from glucose. In good health, mammals synthesize the equivalent in humans of 2 to 13 g/day; under disease or stress, vitamin C synthesis increases up to 100-fold. [2] Under such conditions, vitamin C synthesis may constitute over 90% of glucose utilization – placing a heavy burden on the liver and arguing that vitamin C must have exceedingly important functions in diseased and stressed states.

Three times in mammals – in bats, certain rodents (guinea pigs and capybaras), and the Haplorrhini branch of the primates (containing tarsiers, monkeys, apes, and humans) – the ability to synthesize vitamin C was lost. [1] The loss in the Haplorrhini line was triggered by a retroviral infection about 60 million years ago.

The loss of vitamin C must have had a selective advantage at the time in order to triumph. Whether that selective advantage would still hold today is unknown. Since most Haplorrhini today obtain the human equivalent of 1 to 4 g/day of vitamin C from diet, it’s plausibly the case that any advantage from loss of C synthesis would hold only for those obtaining gram doses of vitamin C through diet or supplements.

Clinical Experience With High-Dose Vitamin C Therapy

A few unconventional doctors have generated most of the clinical experience with high-dose vitamin C therapy.

Fred R. Klenner, a general practitioner from Reidsville, North Carolina, was the pioneer. In the 1940s and 1950s, he found that viral diseases, notably pneumonia and polio, could be cured or greatly improved by intravenous sodium ascorbate of up to 200 g/day. (He favored the pH-neutral sodium ascorbate over conventional acidic versions.) Vitamin C was first isolated in 1932 and first synthesized in 1934, so Klenner was a very early adopter. [3]

Klenner’s maxim was that the patient should “get large doses of vitamin C in all pathological conditions while the physician ponders the diagnosis.” [4]

Irwin Stone and Linus Pauling popularized vitamin C therapies in the late 1960s and early 1970s.

Persuaded by Stone and Pauling, a doctor named Robert Cathcart, who had previously invented an improved artificial hip, began using high-dose vitamin C when he took up general practice in Incline Village, Nevada.

He soon made an interesting discovery:

In 1970, I discovered that the sicker a patient was, the more ascorbic acid he would tolerate by mouth before diarrhea was produced. At least 80% of adult patients will tolerate 10 to 15 grams of ascorbic acid … The astonishing finding was that all patients … can take greater amounts of the substance orally without having diarrhea when ill or under stress. [5]

Cathcart presented this figure showing how various diseases affected vitamin C tolerance:

Over the next two decades, Dr. Cathcart treated over 12,000 patients with high-dose vitamin C. He found that vitamin C “markedly alters the course of many diseases.” [3] In his experience, Dr. the limit of bowel tolerance was a “convenient and clinically useful measure of ascorbate need”:

The maximum relief of symptoms which can be expected with oral doses of ascorbic acid is obtained at a point just short of the amount which produces diarrhea. The amount and timing of the doses are usually sensed by the patient. The physician should not try to regulate exactly the amount and timing of these doses because the optimally effective dose will often change from dose to dose… The patient tries to TITRATE between that amount which begins to make him feel better and that amount which almost but not quite causes diarrhea. [5]

Recall that in animals, vitamin C synthesis rises as much as 100-fold under disease. In humans, the limit of bowel tolerance rises up to 20-fold during illness. This suggests that bowel tolerance limit is an indicator of need.

Dr. Cathcart found that vitamin C was helpful in combination with antibiotics against bacterial infections:

The effect of ascorbic acid is synergistic with antibiotics and would appear to broaden the spectrum of antibiotics considerably….

A most important point is that patients with the bacterial infections would usually respond rapidly to ascorbic acid plus a basic antibiotic determined by initial clinical impressions. [5]

Unfortunately, vitamin C didn’t help much against fungal infections:

Although ascorbic acid should be given in some form to all sick patients to help meet the stress of disease, it is my experience that ascorbate has little effect on the primary fungal infections. Systemic toxicity and complications can be reduced in incidence. [5]

Overall, Dr. Cathcart’s experience was that benefits of vitamin C therapy could be huge.

The method produces such spectacular effects … as to be undeniable. [5]

It’s Not Easy to Test Vitamin C In Clinical Trials

Cathcart notes:

Either this titration method or large intravenous doses are absolutely necessary to obtain excellent results. Studies of lesser amounts are almost useless. The oral method cannot by its very nature be investigated by double blind studies because no placebo will mimic this bowel tolerance phenomenon. [5]

The Danger of Induced Scurvy

I developed scurvy at the nadir of my own chronic infection, so I pass this from Dr. Cathcart along as a warning:

Well-nourished humans usually contain not much more than 5 grams of vitamin C in their bodies….

If a disease is toxic enough to allow for the person’s potential consumption of 100 grams of vitamin C, imagine what that disease must be doing to that possible 5 grams of ascorbate stored in the body. A condition of ACUTE INDUCED SCURVY is rapidly induced. [5]

Anyone with a chronic infection, certain or suspected, should be careful to supplement gram doses of vitamin C.

How Does Vitamin C Work?

Dr. Cathcart’s explanation for the benefits of high-dose vitamin C is that exogenous vitamin C comes with high-energy electrons suitable for transfer to the molecules involved in respiratory bursts:

Conventional wisdom is correct in that only small amounts of vitamin C are necessary for this [antioxidant] function because of its [recycling and] repeated use. The point missed is that the limiting part in nonenzymatic free radical scavenging is the rate at which extra high-energy electrons are provided through NADH to re-reduce the vitamin C and other free radical scavengers. When ill, free radicals are formed at a rate faster than the high-energy electrons are made available. Doses of vitamin C as large as 1-10 g per 24 h do only limited good. However, when ascorbate is used in massive amounts, such as 30-200+ g per 24 h, these amounts directly provide the electrons necessary to quench the free radicals of almost any inflammation. Additionally, in high concentrations ascorbate reduces NAD(P)H and therefore can provide the high-energy electrons necessary to reduce the molecular oxygen used in the respiratory burst of phagocytes. In these functions, the ascorbate part is mostly wasted but the necessary high-energy electrons are provided in large amounts. [6]

This explanation would be consistent with cell biology studies showing that vitamin C is consumed rapidly during phagocytosis:

The high concentration of ascorbate in leucocytes and its rapid expenditure during infection and phagocytosis suggests a role for the vitamin in the immune process. Evidence published to date shows an involvement in the migration and phagocytosis by macrophages and leucocytes … [7]

However, other mechanisms have been proposed by which vitamin C may support immunity:

  • Another early view was that vitamin C helps by destroying histamine, which may be produced in excess under conditions of stress. [8]
  • A 2008 paper from Japan points to a third mechanism: that the oxidized form of vitamin C, dehydroascorbate, has strong antiviral activity in vitro. It may be that the benefit from ingesting high-dose vitamin C comes not from the C itself, but from higher levels of its oxidized waste product, dehydroascorbate [9].

The Japanese finding may supply the best explanation for why, in clinical experience, vitamin C is most effective against viral infections. Phagocytic respiratory bursts are more important for bacterial than viral defense.

Since animals upregulate ascorbate production under all kinds of stress, not just viral infections, it seems probable that vitamin C aids health by multiple pathways, not only by antiviral activity.

Safety

Vitamin C is extremely safe. Intravenous doses of 120 g/day given to cancer patients have been well tolerated. [10]

One of the reasons doctors give for avoiding vitamin C is fear that it might cause kidney stones. However, Cathcart believed vitamin C was beneficial for kidney stones:

It is my experience that ascorbic acid probably prevents most kidney stones. I have had a few patients who had had kidney stones before starting bowel tolerance doses who have subsequently had no more difficulty with them. Acute and chronic urinary tract infections are often eliminated; this fact may remove one of the causes of kidney stones. [5]

Veterinarians Aren’t Afraid to Supplement Vitamin C

In animals such as chickens that lack the ability to synthesize vitamin C, vitamin C is recognized as a means of supporting bacterial and viral immunity. [11]

Conclusion

Based on Cathcart’s testimony, thousands of patients with infectious diseases have benefited from high-dose vitamin C. Although mechanisms are not well understood, vitamin C probably helps along multiple pathways.

A well-tested therapeutic strategy would be to take 4 g vitamin C every hour with water until bowel intolerance is reached. The therapy is extremely safe, and its effectiveness is usually apparent within days.

Given its safety and the ease of testing its effectiveness, why shouldn’t every seriously ill person try this therapeutic strategy? Is there any good reason NOT to try it for at least a few days to see if it has an effect?

Vitamin C vs modern medicine

Posted by on September 25, 2010 12 comments

We’ve previously discussed the case of the New Zealand farmer who was left for dead by his doctors, but recovered from a viral infection thanks to 100 g/day vitamin C. (He also now holds the record for the quickest known recovery from hairy cell leukemia!)

Tomorrow, I’ll say a bit more about vitamin C and immunity. But, since I’ve been posting videos on Saturdays lately, let’s keep that tradition going.

Here is a fascinating video, from New Zealand’s version of 60 Minutes, showing the progression of Alan Smith’s case from death’s door to recovery. Highly recommended! (Hat tip: C: the blog.)

UPDATE:  See the fascinating follow-up video, linked by angelyne in the comments, made by 60 Minutes a month after the first one. Toward the end it tells the story of an Australian girl who had been in a coma for a month. After learning of Alan Smith’s recovery, her family persuaded the hospital to put her on intravenous vitamin C. She partially recovered, her lungs cleared and she was taken off respiratory support. But then the hospital took her off vitamin C. She died soon after. Very frustrating, since the fears of vitamin C toxicity are greatly exaggerated.

Obesity: Often An Infectious Disease

Posted by on September 22, 2010 36 comments

In the book we attribute obesity mainly to food toxins and malnutrition. Both are well attested as causes of obesity in animals:

  • The easiest way to induce obesity in animals is to feed them a carb toxin and a fat toxin – e.g. wheat, fructose, or alcohol with polyunsaturated fats or hydrogenated trans-fats.
  • Obesity in animals can also be induced by nutrient deficiencies, as in the “methionine-choline deficient diet.”

These causes also seem to be active in humans:

  • Intake of fructose and polyunsaturated fats is strongly associated with obesity in humans.
  • Famine studies show that those who experience a period of severe malnourishment are more likely to become obese.

However, in general we attribute diseases to three causes: food toxins, malnutrition, and infections. This suggests we should look also for infectious causes of obesity.

Adenoviruses Can Cause Obesity in Humans

The study of “infectoobesity,” or pathogen-induced obesity, got underway with the discovery of four viruses that could induce obesity in animals. These four viruses — canine distemper virus, Rous-associated virus type 7, Borna disease virus, scrapie agent – were not able to infect humans. However, in chickens, mice, sheep, goat, dogs, rats and hamsters, these viruses infect the central nervous system and induce obesity through effects on the brain and nerves. [1,2]

But then an avian adenovirus, SMAM-1, was found that infects humans and induces obesity in chickens. SMAM-1 works by a different mechanism; it acts directly on fat cells. [2]

Subsequently 3 human adenoviruses, AD-36, AD-37, and AD-5, have been found that act directly on human fat cells and are associated with human obesity. [2] A group led by Dr. Nikhil Dhurandhar of Wayne State University in Michigan showed that AD-36 can induce obesity when given to chickens, mice, and marmosets. [1]

AD-36 Can Spread By Contact

In Dr. Dhurandhar’s chicken experiments, the virus spread fairly easily. Chickens that shared a cage with an infected bird showed signs of the virus in their blood within 12 hours, suggesting that the virus can be spread by nose or mouth secretions. [3]

To Get Really Fat, You Need an Adenovirus Infection

A new study [4] has given us new information about the prevalence and effects of AD-36 in humans. The study found that 22% of obese children (that is, children in the top 5 percentiles of BMI), but only 7% of non-obese, have AD-36 antibodies. Moreover, among the obese children, those who were AD-36-antibody-positive were much fatter than the other obese children. It seems the top 0.1% of children in BMI are probably overwhelmingly made up of AD-36-infected children.

Metabolic Benefits?

It may not be all bad news. AD-36 promotes proliferation of fat cells. Thus, while it promotes obesity, it may also help prevent diabetes. By creating a bigger pool of fat cells to help clear excess glucose from the blood, toxicity from hyperglycemia is reduced, at least for a time.

In Dr. Dhurandhar’s experiments, the extra fat cells showed metabolic effects consistent with enhanced glucose clearance. Infected chickens had lower serum cholesterol and lower triglyceride levels. [3] So infected chickens are fatter, but in some respects healthier.

Pathogens May Be The Source of Disease Diversity

Close readers of our book may have noticed that a combination of carb and fat toxins is, we believe, the most common cause of metabolic syndrome, diabetes, and obesity.

Yet there are thin diabetics and obese non-diabetics. How is it that the same cause can produce different diseases?

One thing the adenovirus work is telling us is that the nature of one’s chronic infections may determine how bad diets translate into disease. Toxic and malnourishing diets make disease inevitable, but which disease depends on which pathogens happen to be around to exploit the bad diet and weakened immunity.

Lessons for the Non-Obese

I certainly wouldn’t avoid contact with obese people for fear of contracting AD-36. These pathogens are everywhere and infection is inevitable. Most elderly probably have hundreds of chronic infections.

The key to health is not avoiding germs, but maintaining a powerful immune system that prevents pathogens from causing disease. That means a healthy diet, good nutrition, and immune-enhancing practices like fasting and ketogenic diet days.

Conclusion

It appears that:

  • It’s possible to become obese from food toxins and malnutrition alone;
  • Some – it’s not yet clear what fraction – obese people do become obese from food toxins and malnutrition alone;
  • But to become really obese, or to become obese really young, you may need a viral infection to help the obesity along.

In the book, we focus on elimination of food toxins and malnutrition as weight-loss steps. The Perfect Health Diet, controlled to 2,000 calories per day, is a weight loss diet for the obese as well as a healing diet for the metabolic derangements that underly obesity.

What the evidence for adenoviruses in obesity is telling us is that the obese may need to take another dietary step as well:  autophagy-promoting steps like fasting. Autophagy is a primary immune mechanism against viruses, so fasting enhances viral immunity.

As always, we recommend that fasts include substantial amounts of coconut oil to help the liver make ketones and relieve the burden on the liver and the risks of glucose deficiency.
