A new review of the body of research on athletic performance and vitamin D suggests that adequate vitamin D levels in athletes could dramatically improve their performance.
Vitamin D is a steroid hormone that is activated in the kidneys; when activated, it regulates more than 1,000 genetic functions. This number seems to grow, touting the importance of vitamin D with every study published. If you have been reading my blog entries, you know that I have posted many blogs about vitamin D.
Researchers involved in this study reviewed the world’s literature for evidence that vitamin D affects physical and athletic performance. Numerous studies, particularly in the German literature in the 1950s, show vitamin D-producing UV light improves athletic performance. There is also a lot of research indicating physical and athletic performance varies in relation to vitamin D levels; it peaks when vitamin D levels peak, declines as levels decline.
What I found incredibly interesting is that Vitamin D also increases the size and number of fast twitch muscle fibers which could make an athlete more pwerful. It is apparent from this study and others that vitamin D levels are directly associated with musculoskeletal and therefore athletic performance.
The levels needed for these affects seem to be above 50ng/dl. As I wrote about in a previous blog levels may also protect the athlete from several acute and chronic medical conditions. Here’s a link to hat entry (Athletes Like The Rest of Us, Need More Vitamin D).

Another study touting the benefits of proper vitamin D levels suggests a link between low levels of vitamin D and cardiac risk has been published. This study shows that vitamin-D deficiency is associated with both cardiovascular mortality and all-cause mortality.
The study was published in the June 23, 2008 issue of the Archives of Internal Medicine and conducted by a group led by Dr Harald Dobnig (Medical University of Graz, Austria).
The researchers note that an estimated 50% to 60% of people do not have satisfactory vitamin-D levels, and this is probably related to factors such as urbanization, demographic shifts, decreased outdoor activity, air pollution and global dimming, and decreases in the cutaneous production of vitamin D with age.
The minimum optimal serum level of 25-hydroxyvitamin D that I want to see in patients is 50 ng/mL, and levels lower than this are may bey related to compromised bone-mineral density, falls, and fractures and more recently levels lower than this have been linked to cancer and immune dysfunction, as well as cardiovascular disease, hypertension, and metabolic syndrome.
The researchers point out that recent studies have shown an association of low 25-hydroxyvitamin-D levels with important cardiovascular risk factors, supporting previous findings that demonstrated positive effects of vitamin D and its analogs on cardiovascular system health. “Together, these findings strongly suggest that 25-hydroxyvitamin D has beneficial effects, some involving the cardiovascular system, that are independent of calcium metabolism,” they comment.

Well, being somewhat of a technology geek and seeing that the iphone’s touch screen will help simplify some of the processes in my clinic, I went out and purchased a 3G iphone on July 11th. I woke up at 5am, had some coffee then headed out to the AT&T store near my house. I was about the 25th person in line; I was fine with this but it was a CHILLY Portland morning. I made some friends, only a couple of people became a little aggressive but nothing came of their aggressiveness. In fact, one of the angry people in line was actually a person from craigslist getting paid to stand in line for someone…..I guess he was just doing his job.
To cut to the point of this blog; I was searching through the new iphone/ipod touch applications and found “Steps”. This is a program that utilizes the movement sensors in the iphone as a pedometer. It uses the data from the motion sensors to tell you how many steps you have taken. Now, some of you may be aware that there is a 10,000 steps movement going on around the world; it is a great and simple movement that encourages people to increase the number of steps they take per day to 10,000. The average person takes between 5000-7000 steps per day. Sedentary individuals may get as few as 2000-3000. By using a pedometer…..or more important to this blog, your iphone, to measure your daily steps. By using this information you can gradually increase the number of steps you take to finally reach 10,000; studies have shown that this will help you lose weight, feel better and even decrease your risk of having cardiovascular disease.
Portland’s a GREAT city for this program and I am in the process of writing a brief but informative booklet about how to do it properly. Feel free to email firstname.lastname@example.org or call 503-866-9739 for more info. For those of you who would participate but have knee, ankle, hip or back pain, call to schedule an appointment with me and I can tell you if the tools I have can help you live pain-free and function optimally.

Just 30 days of eating fast food combined with minimal exercise (walking less than 5000 steps in a day, the average person takes between 5000-7000 steps per day) is all it takes to impair liver function. The Liver is the “Master Chemist” of your body. Scientists reported this disturbing information in a study published in Gut, a peer review journal for health professionals and researchers in gastroenterology and hepatology. This information comes at a time when we are all a little strapped for money and fast food is convenient and inexpensive. To those of us in the healthcare and especially nutrition industry, this information comes as no surprise. I personally have seen a few cases of NASH (non-alcoholic steatohepatitis); in the past, this liver condition was only seen in alcoholics.
In the study, the researchers took 18 healthy people (12 men, 6 women; known as the intervention group) and a matched control group (individuals who did not eat fast food and who walked more than 5000 steps per day). The subjects in the intervention group ate at least two meals at popular fast food restaurants each day and restricted their physical activity to not more than 5000 steps per day. Their mission was to increase their body weight by 5 – 15% by doubling their normal daily caloric intake and adopting a sedentary lifestyle for four weeks.
In order to monitor liver function, blood samples were taken at the beginning of the study and at regular intervals thereafter. One way to identify liver damage is to measure alanine aminotransferase (ALT), an enzyme in the liver. After only a single week on the fast food diet, ALT levels in the intervention group began to climb. ALT is not the only blood chemistry marker for liver function but it is the most specific in a baseline blood chemistry panel.
By the end of the four weeks, seventeen of the eighteen subjects had met their goal of increasing their body weight by 5 – 15%, with 5 of the eighteen subjects reaching the 15% mark. Thirteen of the study participants developed pathological ALT, which was evident in most subjects after the first week. Those in the control group did not experience any such increases.
It doesn’t take a genius to see that a sedentary lifestyle of fast food gluttony will rapidly lead to ill health. According to a Saint Louis University press release, it may be possible to reverse liver damage caused by such a lifestyle. The way to undo the damage to the liver and other vital organs is to adopt a healthy lifestyle and stop eating fast foods.
Brent Tetri, M.D., a professor of internal medicine at the Saint Louis University Liver Center and expert on non-alcoholic fatty liver disease, conducted a similar experiment using mice. “There’s strong evidence now that a fast-food type of diet — high in fat and sugar, the kind of diet many Americans subsist on — can cause significant damage to your liver and have extremely serious consequences for your health,” he explains. “The good news,” he continues, “is that most people can undo this damage if they change their diet and they keep physically active. If they don’t, however, they are asking for trouble.”
In the study conducted by Dr. Tetri, mice were given a diet that was 40% fat and loaded with high-fructose corn syrup, a sweetener commonly found in sodas, juices, and bottled sauces and dressings. The mice were also kept sedentary, emulating the lifestyle of many Americans. After four weeks, the mice displayed an increase in liver enzymes and the onset of glucose intolerance, known to be a marker for type II diabetes.
Dr. Tetri points out that while not all fast food necessarily causes liver damage, the problem is a diet containing too many calories with too much fat and sugar (typical in fast food meals consisting of burgers, fries and sodas). Tetri adds, “The fact we’re starting to see kids with liver disease should really be a wake-up call for anyone eating a diet high in fat and sugar and who’s not physically active.” He offers some encouragement to fast food junkies: “Even for those people with the worst kind of diets, it’s not too late to start exercising and eating right.”

A study published in The Clinical Journal of Pain in it’s March/April, 2008 issue links back pain to gastrointestinal (GI) symptoms. This Australian study analyzed data from 38.050 women of different ages who had varying GI symptoms ranging from constipation, hemorrhoids, diarrhea and other bowel problems.
The results showed that with an increase of back pain frequency from “rarely” to “sometimes” to “often”, there was a direct increase in GI symptoms. While the study did not evaluate the cause for this link, it does seem to be strong. Clinically, I have found this to be the case.
Are chiropractors treating GI symptoms with adjustments? Some may make this claim. I would like to point out that some or maybe even many of our back pain patients, especially women, may have concomitant GI problems that are going undetected and maybe even untreated.
At Optimum Function, I have made it my goal to always take this into consideration. This is one of the main reasons that I have spend the time and effort to receive post-graduate training in functional medicine and nutrition and have come up with functional medicine and nutritional programs.

Heartburn is often mistakenly labelled as GERD or gastroesophageal reflux disorder (or disease). For some time now, HCL or hydrochloric acid has been falsely deemed the culprit. Clinically, I, and many other functional medicine doctors have found that patients with heartburn often have too little HCL, this is known as hypochlorhydria. HCL is needed for proper digestion of proteins, absorption of critical nutrients like vitamin B12 and Zinc and is also needed to signal the pancreas to secrete its enzymes that are necessary for the further breakdown and absorption of fats, proteins and carbohydrates.
At Optimum Function in Portland, Oregon, I have put together a series of functional medicine programs that investigate and treat functional conditions like “heartburn” through nutritional and natural avenues of treatment. Click Here to find out more
I recently participated in a 5 month functional medicine program created by doctors Dicken Weatherby and Ron Grisanti. There was a lot of clinical discussion on this topic and Dr. Weatherby has put together an excellent video explaining why heartburn is often mistakenly associated with too much stomach acid.

Well, with all the exciting programs that I have developed with help from some of my patients (you know who you are), I am left reflecting on the questions that seem to be on many of my new patients’ minds:
- Can chiropractors order blood and lab work?
- Do chiropractors work on shoulders, knees, etc.?
- Does “Nutrition Counseling” mean “Supplement Counseling”?
- What is Functional Medicine?
First, let me say that not all chiropractors will practice the same. This fact is both the beauty of chiropractic and in some extents, the bane of our profession’s existence. The variety and individualism that exists in the chiropractic profession does so at the expense of a solid identity at times.
I do, firmly believe that the treatments offered at Optimum Function and other, progressive chiropractic clinics represent the evolution of chiropractic. So…YES! At least here in Portland, Oregon, chiropractors can (and in my opinion, should) order blood work. This is one of the reasons I teamed-up with Quest Diagnostics and Doctor’s Choice to develop the “Dr. Irving Panel”, which, at $89* is INCREDIBLY comprehensive (I’ve included everything from cholesterol to thyroid hormones, glucose and more!). If you are being treated with functional medicine, nutrition, or any of the other wellness-based treatments without first having a comprehensive blood chemistry run and evaluated correctly, your doctor may be missing some key elements. Each and every one of use has a different chemistry that affects the way we do things like: produce hormones, metabolize fats, proteins etc. and more. The values in a comprehensive blood chemistry , in the hands of someone who knows what to look for may prove to be invaluable.
Also, at Optimum Function, restoring musculoskeletal function is one of my main focuses…..even if it’s restoring it in your knees, ankles, shoulder etc. In fact, back pain often arises from weaknesses and/or imbalances in these areas. If your doctor is not looking at these key components, they may be missing some key information that may be exactly why you never quite feel 100%.
At Optimum Function in southeast Portland, Oregon, “Nutritional Counseling” does not equate to “Supplement Counseling”. While supplements are used when necessary to improve your health status, my main focus is on FOOD. It’s what we’re made of and everyday, the healthcare community finds out that when balanced and nutritious, the food we eat produces healthy results the like of which no drug on the market today can compare to.
Lastly, in addition to chiropractic, massage, and nutrition, I utilize the principles of functional medicine in the treatment of my patients. What is it? Well, it’s the art of figuring out (to the best of my ability)what unique processes are going on in your body that have produced your own unique health status in the present. In addition, this means I will look to things like lifestyle, dietary habits and other things that may have predisposed you to your current health status. With your help, I will look to uncover what was or were the triggers that sent you down the path to your current health status and what is keeping you there. This is individualized healthcare! And it’s VERY exciting.
