Take a walking vacation

If you're planning a vacation, why not consider a walking vacation?

The concept is really taking off. All you need is a pair of comfortable shoes and an interesting locale. More and more services are popping up to help you plan fun and interesting destinations and itineraries. One such catalog can be found at http://walking.about.com/od/tours/a/walkingvacation_3.htm

Lengthier walks may require some advance planning and toting some supplies. Don't forget the water!

From a health viewpoint, a walking vacation sure beats the heck out of a cruise that packs on 12 pounds of extra weight from the 24-hour a day buffet. If you're in the midst of a weight loss effort, several hours of walking through interesting locales and scenery can make it effortless.

There's loads of neat places to visit from a walker's perspective. One interesting website is www.waterfallwalks.com that lists trails that provide spectacular views of waterfalls.

Another variation on this theme is biking vacations. My wife and I are trying to set the time aside for a biking tour of wineries in the French countryside. That's our kind of multi-tasking!

"Expanded indications for implantable defibrillators"

So reads the headline on a magazine I received recently (along with thousands of my colleagues) from a major hospital system.

It goes on to say: "In January 2005, indications for implantable cardioverter-defibrillators (ICDs) were substantially broadened [emphasis ours] to include most patients with a left ventricular ejection fraction (EF) of 35% or less. This change translates into a 2- to 3-fold increase in the number of Medicare beneficiariries eligible for ICDs."

Ka-ching!!! Hear the money piling up in the bank?

The device manufacturers are constantly churning data and lobbying for reimbursement to expand the use of their devices to more and more people. Defibrillators in particularly are generally a $25,000 to $50,000 opportunity for the device manufacturer alone, not counting the costs incurred at the hospital for implantation.

Beware. As reimbursement for stents and other procedures diminishes, expect a sudden "demand" for more and more people to get implantable defibrillators. Better yet, stay away from the whole issue by preventing your heart attack.

Get a heart scan--but then don't delay taking action!

I just came from one of the local hospitals after having performed a heart catheterization on a patient I met earlier this week.

Jack had gotten a heart scan a year ago with a score of 246, placing him in the 76th percentile. The "event" rate with this percentile rank is around 3% per year--not very high but enough to pose risk over a long period.

Jack chose to ignore his score. After all, the pressures of work at the University, maintaining his home and yard, etc. consumed all his energies. He came to my office--now one year after his scan--and told me about the chest pressure he was getting. Initially, his chest pains occurred with extended walking. In the past week, however, Jack was experiencing chest pressure with just walking 30 feet.

This pattern of increasing symptoms is called "accelerated angina", meaning that Jack was rapidly heading towards a heart attack. So I advised a heart catheterization in near future.

Jack's catheterization showed extensive plaque including a 50% blockage in the mainstem artery and 90% in the artery to the front of the heart (left anterior descending artery). Jack is going to have a bypass operation tomorrow.

What if Jack hadn't ignored his heart scan from a year ago? Well, I'd be very confident in saying that he would not be undergoing bypass surgery tomorrow.

The lesson: Don't dilly-dally on taking action to keep your plaque from growing. While it's not an emergency, it can easily become one if you choose to ignore your scan.

Feel that nudge in your back?

You feel that nudge in your back? That's your local hospitals competing for your bypass surgery business.

Just this morning while watching a morning news show, I saw three advertisements for hospital bypass surgery programs. One ad featured a man in his 50s telling his story:"The cardiologist determined immediately that I needed a triple bypass operation. My family and I are very grateful to _____ hospital!"

In what other field is failure celebrated so prominently? When I see these ads, I hear "My doctors failed to provide early detection and then prevent what became a life-threatening condition, even though heart disease is a chronic process that requires decades to develop." What if our man said instead,"I had a heart scan and my score was high. So I was shown why I had so much plaque. They then showed me how to control and even reduce the amount of plaque I had. I'm living safely and symptom-free without need for surgery or procedures."

Of course, the hospital is out $60,000-100,000 for the surgery. How else could they afford ad campaigns costing several million dollars a year? See these advertisements for what they are: Marketing generated by profit-seeking businesses competing for your dollars--lots of them.

Throw away total cholesterol!

Richard's total cholesterol without treatment was 186 mg/dl. "That's great!" his doctor declared, referring to the conventional dictum that total cholesterols less than 200 carry low risk. Several fingersticks in a mall kiosk set up by a local hospital to check total cholesterols confirmed Richard's low number.

But after Richard's unexpected hospitalization and two stents for severe coronary blockages, he demanded better answers.

Tragically, the answer was there all along: Despite a "favorable" total cholesterol, his HDL ("good") cholesterol was a miserable 32 mg (ideal >60 mg).

Total cholesterol is actually the sum total of HDL cholesterol, LDL cholesterol, with a contribution from triglycerides. That's why a low total cholesterol can conceal a low HDL.

This situation is quite common. And low HDL is accompanied by a constellation of other undesirable causes of heart disease, most notably small LDL.

Don't accept total cholesterol as your sole measure of risk. It's nearly worthless. If you live in Bangladesh or a third world country, well perhaps that's the best you can get. But if you live in the U.S. or developed world, it's absurd to rely on total cholesterol.

Smart Start not so smart




Kellogg's has crafted a campaign to support the American Heart Association featuring acress Sela Ward. Her attractive face, familiar to many TV and movie viewers, does add a comforting face to their efforts.

What's in this cereal made by the manufacturers of Pop-Tarts, Cheez-It, Rice Krispies, and Chips Deluxe cookies?

There are, indeed, some healthy ingredients: oat bran, potassium; you can even get a version made with soy protein. But there's sugar listed as the second ingredient. High-fructose corn syrup is also listed prominently. (Remember this issue? High-fructose corn syrup causes overwhelming sugar cravings, causes your triglycerides to skyrocket, and is probably among the principal food ingredients that make you obese.)

Upon detailed questioning of my patients struggling to lose weight, this and products like it are often among the "healthy" foods they've gravitated towards. We spend a great deal of time dissuading them of this idea.

A one-cup serving of Smart Start is low in fat (1 gram) but contains 43 grams of carbohydates, of which there are 14 grams of sugar. There are a meager 3 grams of fiber. To me, this sounds like a cupcake.

The Kellogg's people are exceptionally clever marketers. Partner with the American Heart Association and movie stars? Brilliant!

You should trust food manufacturer advertising about as much as you trust drug manufacturer advertising, which is to say not at all.

Kellogg's sold $10 billion dollars of food products last year. They are the world's leading producer of breakfast cereals. They are a leading producer of convenience foods: cookies, crackers, cereal bars, and frozen waffles under the brands Keebler, Pop-Tarts, Eggo, Cheez-It, Nutri-Grain, Rice Krispies, Famous Amos, and Kashi.

Can they cash in on healthy trends? They'll certainly try.

Does anybody have a normal vitamin D level?

We now routinely check everyone's vitamin D blood level at the start of the program. (The measure to obtain is 25-OH-Vitamin D3. This is not to be confused with 1,25-OH2-vitamin D3, which is a kidney function measure.)

Of the 10 people with levels drawn today, none were even close to normal levels (which we define as 50 ng/ml)--not a single one.

The majority were in the range of severe deficiency (<20 ng/ml). Only two had levels in the 30s. None had higher. (Remember: I'm talking about people in Wisconsin, a terribly sunlight-deprived area much of the year. This might not apply quite as vigorously to Florida residents or others in sun-exposed regions.)

Curiously, I've also seen several people this week who had extraordinary quantities of coronary plaque on their heart scans (scores >1000), all of whom had extremely low vitamin D levels. One of these people had fairly unimpressive lipoproteins, with very minimal abnormalities identified. (This is quite unusual, by the way.) It makes you wonder if a profound deficiency of vitamin D is sufficient to act on its own as an instigator of coronary plaque.

The more we examine the issue of vitamin D deficiency, the more fascinating it gets. I suspect we've just scratched the surface and there's a lot more to learn about this tremendously interesting nutrient. Nonetheless, with what we're seeing in our experience, I'm urging everyone to get a blood vitamin D level.

Don't believe your LDL cholesterol!

Harry's case is typical. For years, his doctor told him his LDL cholesterol of 123 mg was okay. But a heart scan score of 490 (90th percentile at age 52) made him question just where his coronary plaque came from.

Lipoprotein analysis told a very different story: His LDL particle number was 2400 nmol, meaning his trueLDL was more like 240 mg, nearly double the value of LDL obtained through his doctor. Harry had other sources of risk, too, but the LDL particle number was a clear stand-out.

Why does this happen? How can LDL cholesterol be so terribly inaccurate?

LDL cholesterols obtained in virtually all labs are not measured, they're calculated. The calculation was developed in the 1960s by Dr. Friedewald at the National Institutes of Health and therefore goes by his name (the Friedewald calculation). Dr. Friedewald derived this simple calculation to permit doctors across the U.S. to obtain LDL cholesterols, which were technically difficult to measure in those days by using measured HDL, total cholesterol and triglycerides.

Doctors were told that the only time that the Friedewald calculated LDL was inaccurate was when triglycerides exceeded 400 mg. So most family practitioners and internists still believe that calculated LDL's are, for the most part, quite accurate.

Nothing could be further from the truth. When LDL's are actually meaured, you find that LDL is rarely accurate. In fact, in our experience, inaccuracy of 30-50% is the rule, sometimes 100%. The one telltale hint that calculated LDL is wrong is when HDL is <50 mg--that's nearly everybody.

So what's your LDL? You won't really know unless it's measured. Our preferred method is NMR (LipoScience) LDL particle number, probably the most accurate of all. Second best: apoprotein B, direct m

For the sake of convenience: Commercial sources of prebiotic fibers

Our efforts to obtain prebiotic fibers/resistant starches, as discussed in the Cureality Digestive Health Track, to cultivate healthy bowel flora means recreating the eating behavior of primitive humans who dug in the dirt with sticks and bone fragments for underground roots and tubers, behaviors you can still observe in extant hunter-gatherer groups, such as the Hadza and Yanomamo. But, because this practice is inconvenient for us modern folk accustomed to sleek grocery stores, because many of us live in climates where the ground is frozen much of the year, and because we lack the wisdom passed from generation to generation that helps identify which roots and tubers are safe to eat and which are not, we rely on modern equivalents of primitive sources. Thus, green, unripe bananas, raw potatoes and other such fiber sources in the Cureality lifestyle.

There is therefore no need to purchase prebiotic fibers outside of your daily effort at including an unripe green banana, say, or inulin and fructooligosaccharides (FOS), or small servings of legumes as a means of cultivating healthy bowel flora. These are powerful strategies that change the number and species of bowel flora over time, thereby leading to beneficial health effects that include reduced blood sugar and blood pressure, reduction in triglycerides, reduced anxiety and improved sleep, and reduced colon cancer risk.

HOWEVER, convenience can be a struggle. Traveling by plane, for example, makes lugging around green bananas or raw potatoes inconvenient. Inulin and FOS already come as powders or capsules and they are among the options for a convenient, portable prebiotic fiber strategy. But there are others that can be purchased. This is a more costly way to get your prebiotic fibers and you do not need to purchase these products in order to succeed in your bowel flora management program. These products are therefore listed strictly as a strategy for convenience.

Most perspectives on the quality of human bowel flora composition suggest that diversity is an important feature, i.e., the greater the number of species, the better the health of the host. There may therefore be advantage in varying your prebiotic routine, e.g., green banana on Monday, inulin on Tuesday, PGX (below) on Wednesday, etc. Beyond providing convenience, these products may introduce an added level of diversity, as well.

Among the preparations available to us that can be used as prebiotic fibers:

PGX

While it is billed as a weight management and blood sugar-reducing product, the naturally occurring fiber--α-D-glucurono-α-D-manno-β-D-manno- β-D-gluco, α-L-gulurono-β-D mannurono, β-D-gluco-β- D-mannan--in PGX also exerts prebiotic effects (evidenced by increased fecal butyrate, the beneficial end-product of bacterial metabolism). PGX is available as capsules or granules. It also seems to exert prebiotic effects at lower doses than other prebiotic fibers. While I usually advise reaching 20 grams per day of fiber, PGX appears to exert substantial effects at a daily dose of half that quantity. As with all prebiotic fibers, it is best to build up slowly over weeks, e.g., start at 1.5 grams twice per day. It is also best taken in two or three divided doses. (Avoid the PGX bars, as they are too carb-rich for those of us trying to achieve ideal metaobolic health.)

Prebiotin

A combination of inulin and FOS available as powders and in portable Stick Pacs (2 gram and 4 gram packs). This preparation is quite costly, however, given the generally low cost of purchasing chicory inulin and FOS separately.

Acacia

Acacia fiber is another form of prebiotic fiber.  RenewLife and NOW are two reputable brands.

Isomalto-oligosaccharides

This fiber is used in Quest bars and in Paleo Protein Bars. With Quest bars, choose the flavors without sucralose, since it has been associated with undesirable changes in bowel flora.

There you go. It means that there are fewer and fewer reasons to not purposefully cultivate healthy bowel flora and obtain all the wonderful health benefits of doing so, from reduced blood pressure, to reduced triglycerides, to deeper sleep.

How Not To Have An Autoimmune Condition


Autoimmune conditions are becoming increasingly common. Estimates vary, but it appears that at least 8-9% of the population in North America and Western Europe have one of these conditions, with The American Autoimmune Related Diseases Association estimating that it’s even higher at 14% of the population.

The 200 or so autoimmune diseases that afflict modern people are conditions that involve an abnormal immune response directed against one or more organs of the body. If the misguided attack is against the thyroid gland, it can result in Hashimoto’s thyroiditis. If it is directed against pancreatic beta cells that produce insulin, it can result in type 1 diabetes or latent autoimmune diabetes of adults (LADA). If it involves tissue encasing joints (synovium) like the fingers or wrists, it can result in rheumatoid arthritis. It if involves the liver, it can result in autoimmune hepatitis, and so on. Nearly every organ of the body can be the target of such a misguided immune response.

While it requires a genetic predisposition towards autoimmunity that we have no control over (e.g., the HLA-B27 gene for ankylosing spondylitis), there are numerous environmental triggers of these diseases that we can do something about. Identifying and correcting these factors stacks the odds in your favor of reducing autoimmune inflammation, swelling, pain, organ dysfunction, and can even reverse an autoimmune condition altogether.

Among the most important factors to correct in order to minimize or reverse autoimmunity are:


Wheat and grain elimination

If you are reading this, you likely already know that the gliadin protein of wheat and related proteins in other grains (especially the secalin of rye, the hordein of barley, zein of corn, perhaps the avenin of oats) initiate the intestinal “leakiness” that begins the autoimmune process, an effect that occurs in over 90% of people who consume wheat and grains. The flood of foreign peptides/proteins, bacterial lipopolysaccharide, and grain proteins themselves cause immune responses to be launched against these foreign factors. If, for instance, an autoimmune response is triggered against wheat gliadin, the same antibodies can be aimed at the synapsin protein of the central nervous system/brain, resulting in dementia or cerebellar ataxia (destruction of the cerebellum resulting in incoordination and loss of bladder and bowel control). Wheat and grain elimination is by far the most important item on this list to reverse autoimmunity.

Correct vitamin D deficiency

It is clear that, across a spectrum of autoimmune diseases, vitamin D deficiency serves a permissive, not necessarily causative, role in allowing an autoimmune process to proceed. It is clear, for instance, that autoimmune conditions such as type 1 diabetes in children, rheumatoid arthritis, and Hashimoto’s thyroiditis are more common in those with low vitamin D status, much less common in those with higher vitamin D levels. For this and other reasons, I aim to achieve a blood level of 25-hydroxy vitamin D level of 60-70 ng/ml, a level that usually requires around 4000-8000 units per day of D3 (cholecalciferol) in gelcap or liquid form (never tablet due to poor or erratic absorption). In view of the serious nature of autoimmune diseases, it is well worth tracking occasional blood levels.

Supplement omega-3 fatty acids

While omega-3 fatty acids, EPA and DHA, from fish oil have proven only modestly helpful by themselves, when cast onto the background of wheat/grain elimination and vitamin D, omega-3 fatty acids compound anti-inflammatory benefits, such as those exerted via cyclooxygenase-2. This requires a daily EPA + DHA dose of around 3600 mg per day, divided in two. Don’t confuse EPA and DHA omega-3s with linolenic acid, another form of omega-3 obtained from meats, flaxseed, chia, and walnuts that does not not yield the same benefits. Nor can you use krill oil with its relatively trivial content of omega-3s.

Eliminate dairy

This is true in North America and most of Western Europe, less true in New Zealand and Australia. Autoimmunity can be triggered by the casein beta A1 form of casein widely expressed in dairy products, but not by casein beta A2 and other forms. Because it is so prevalent in North America and Western Europe, the most confident way to avoid this immunogenic form of casein is to avoid dairy altogether. You might be able to consume cheese, given the fermentation process that alters proteins and sugar, but that has not been fully explored.

Cultivate healthy bowel flora

People with autoimmune conditions have massively screwed up bowel flora with reduced species diversity and dominance of unhealthy species. We restore a healthier anti-inflammatory panel of bacterial species by “seeding” the colon with high-potency probiotics, then nourishing them with prebiotic fibers/resistant starches, a collection of strategies summarized in the Cureality Digestive Health discussions. People sometimes view bowel flora management as optional, just “fluff”–it is anything but. Properly managing bowel flora can be a make-it-or-break-it advantage; don’t neglect it.

There you go: a basic list to get started on if your interest is to begin a process of unraveling the processes of autoimmunity. In some conditions, such as rheumatoid arthritis and polymyalgia rheumatica, full recovery is possible. In other conditions, such as Hashimoto’s thyroiditis and the pancreatic beta cell destruction leading to type 1 diabetes, reversing the autoimmune inflammation does not restore organ function: hypothyroidism results after thyroiditis quiets down and type 1 diabetes and need for insulin persists after pancreatic beta cell damage. But note that the most powerful risk factor for an autoimmune disease is another autoimmune disease–this is why so many people have more than one autoimmune condition. People with Hashimoto’s, for instance, can develop rheumatoid arthritis or psoriasis. So the above menu is still worth following even if you cannot hope for full organ recovery

Five Powerful Ways to Reduce Blood Sugar

Left to conventional advice on diet and you will, more than likely, succumb to type 2 diabetes sooner or later. Follow your doctor’s advice to cut fat and eat more “healthy whole grains” and oral diabetes medication and insulin are almost certainly in your future. Despite this, had this scenario played out, you would be accused of laziness and gluttony, a weak specimen of human being who just gave into excess.

If you turn elsewhere for advice, however, and ignore the awful advice from “official” sources with cozy relationships with Big Pharma, you can reduce blood sugars sufficient to never become diabetic or to reverse an established diagnosis, and you can create a powerful collection of strategies that handily trump the worthless advice being passed off by the USDA, American Diabetes Association, the American Heart Association, or the Academy of Nutrition and Dietetics.

Among the most powerful and effective strategies to reduce blood sugar:

1) Eat no wheat nor grains

Recall that amylopectin A, the complex carbohydrate of grains, is highly digestible, unlike most of the other components of the seeds of grasses AKA “grains,” subject to digestion by the enzyme, amylase, in saliva and stomach. This explains why, ounce for ounce, grains raise blood sugar higher than table sugar. Eat no grains = remove the exceptional glycemic potential of amylopectin A.

2) Add no sugars, avoid high-fructose corn syrup

This should be pretty obvious, but note that the majority of processed foods contain sweeteners such as sucrose or high-fructose corn syrup, tailored to please the increased desire for sweetness among grain-consuming people. While fructose does not raise blood sugar acutely, it does so in delayed fashion, along with triggering other metabolic distortions such as increased triglycerides and fatty liver.

3) Vitamin D

Because vitamin D restores the body’s normal responsiveness to insulin, getting vitamin D right helps reduce blood sugar naturally while providing a range of other health benefits.

4) Restore bowel flora

As cultivation of several Lactobacillus and Bifidobacteria species in bowel flora yields fatty acids that restore insulin responsiveness, this leads to reductions in blood sugar over time. Minus the bowel flora-disrupting effects of grains and sugars, a purposeful program of bowel flora restoration is required (discussed at length in the Cureality Digestive Health section.)

5) Exercise

Blood sugar is reduced during and immediately following exercise, with the effect continuing for many hours afterwards, even into the next day.

Note that, aside from exercise, none of these powerful strategies are advocated by the American Diabetes Association or any other “official” agency purporting to provide dietary advice. As is happening more and more often as the tide of health information rises and is accessible to all, the best advice on health does not come from such agencies nor from your doctor but from your efforts to better understand the truths in health.
