It is hard to believe that August is here but don’t panic, there is plenty of time to get outdoors and enjoy some sunny Vitamin D!
While protection from the sun is very important, too much time indoors playing computer games and watching television can lead to potential problems from lack of exposure to the sun. One must use good judgment and have balance as the potential exists for Vitamin D deficiency due to lack of sun exposure. This problem may be true for individuals who use too much protection or spend most of their day indoors due to occupation or poor health. Therefore, the purpose of this column will be to discuss the importance of Vitamin D for health and wellness.
Vitamin D, a fat-soluble vitamin, is found in food and can be made by your body after exposure to ultraviolet (UV) rays from the sun. The liver and kidney help convert Vitamin D to its active form. It assists with calcium absorption, which is essential for normal development and in forming and maintaining strong bones and teeth. Without it, bones can become thin, brittle and soft. The classic deficiency diseases are rickets in children and osteomalacia in adults. Rickets results in skeletal deformities. Osteomalacia is the softening of bones. Vitamin D is essential for normal bone health and may diminish or prevent the onset of osteoporosis in the elderly.
The requirement for Vitamin D is dependent on age, sex, degree of sun exposure and the amount of pigmentation in the skin. Since it can be produced by the body and retained for long periods of time by the body’s tissues, the precise daily requirement has been difficult to determine. Instead, an Adequate Intake (AI) level has been established. AI is a level of intake sufficient to maintain healthy blood levels of an active form of Vitamin D.
Vitamin D deficiency can occur when dietary intake of it is inadequate, when there is limited sunlight exposure, when the kidney cannot convert Vitamin D to its active form or when it is inadequately absorbed from the gastrointestinal tract. Season, geographic location, time of day, cloud cover, air pollution, sunscreens, living indoors and living in cities where tall buildings block adequate sunlight from reaching the ground affect UV ray exposure. Individuals with limited sun exposure are at risk of Vitamin D deficiency.
Homebound individuals, people living in northern latitudes (e.g. New England, Alaska), individuals who cover their bodies for religious reasons and people whose occupations prevent exposure to sunlight may need to supplement with Vitamin D. Sunscreens with a sun protection factor of 8 or greater will block UV rays that produce it. Older adults have a higher risk for deficiency because the skin’s ability to convert Vitamin D to its active form decreases with age and the kidneys, which help convert it to its active form, do not work as well when people age.
Individuals with pancreatic enzyme deficiency, Chron’s disease, cystic fibrosis, sprue, liver disease, surgical removal of part or all of the stomach or small bowel disease may need extra Vitamin D because it is a fat-soluble vitamin and they have reduced ability to absorb dietary fat. Vitamin D supplements are often recommended for exclusively breast-fed infants because human milk may not contain adequate amount. Consult with your pediatrician on this issue.

The list of diseases such as high blood pressure, diabetes, and stroke that can be managed, cured or prevented is endless. Certainly, cholesterol and heart disease are at the top of the list. Studies clearly demonstrate that managing cholesterol through education, medication, diet and exercise can significantly reduce the risk of heart disease.
Know your numbers. Learn the difference between unsaturated and saturated fats. Make yourself a student of healthy living through diet and exercise. Avoid fads and focus your effort on scientifically proven methods. Many experts feel that those with genetically high cholesterol should use exercise and diet to maintain health but will also need require the addition of a statin drug to manage cholesterol effectively.
There are many methods to lower your LDL (bad cholesterol). However, no method has been proven more successful than statin drugs. Multiple landmark studies confirm that for those individuals needing statin drugs to control their cholesterol, the benefits far outweigh the risks.
By inhibiting an enzyme in the liver, statin drugs limit the liver’s ability to produce cholesterol thereby significantly lowering LDL (bad cholesterol) and triglycerides and modestly increasing HDL (good cholesterol). As a result, their unique benefits include preventing and reducing plaque in arteries, stabilizing existing plaque, reducing inflammation of the arterial wall, and improving overall vascular function. Statin Drugs Include: Lipitor (atorvastatin); Lescol (fluvastatin); Mevacor (lovastatin); Pravachol (pravastatin); Zocor (simvastatin); Crestor (rosuvastatin).
Clinical studies that have shown that statin drugs significantly reduce the risk of heart attack and death in patients with proven coronary artery disease (CAD) and can also reduce cardiac events in patients with high cholesterol levels who are at increased risk for heart disease. And although statins are best known for lowering cholesterol, they may also have several other benefits: they may prevent Alzheimer’s disease, and they may also have a positive impact on diabetes and blood pressure.
Second only to statin drugs, no other method of the prevention of CAD has proven more effective than exercise, specifically aerobic exercise. It is well documented that physically active people have a lower incidence of CAD than sedentary people. For the prevention of CAD, the following exercises are defined as aerobic: High Amount/High Intensity – a caloric equivalent of jogging 20 miles per week at 65 -80 percent intensity, Low Amount/High Intensity – a caloric equivalent of jogging 12 miles per week at 65 to 80 percent intensity, Low Amount/Moderate Intensity – a caloric equivalent of walking 12 miles per week at 40 to 55 percent intensity.
Exercise is a valuable prevention tool on many levels: it reduces weight, LDL, and blood pressure, and it increases HDL. Research has found that the amount of exercise matters more than the intensity. For example, those exercising 5 or more days per week benefited more than those exercising less often. However, it is important to remember that ALL exercise groups showed improvement.
Following a Mediterranean diet is one way you can reduce CAD and cut your risks for other diseases. While no Mediterranean diet has more value than another, the following equation highlights the factors that make a Mediterranean diet so valuable. First, eat a variety of fruits, vegetables, whole grains, beans, nuts, and seeds, with olive oil as an important source of fat. Then, add moderate amounts of fish, poultry and fresh dairy. Finally, subtract red meat from your diet, or at least limit your consumption.
The Dietary Approaches to Stop Hypertension (DASH) diet is the American version of the Mediterranean diet and has been found to reduce blood pressure and LDL levels. It is rich in fruits and vegetables, moderate in low-fat dairy, and low in animal protein. It promotes the use of legumes and nuts as plant sources of protein.
Along with increasing your plant-based foods and decreasing your consumption of red meat, you may also want to replace some of the carbohydrates in your diet with proteins or monounsaturated fats. This switch can improve lipid levels.
Dietary soluble fibers such as pectin, wheat dextrin, and oat products will reduce LDL. Some suggest that a combination of soluble fiber with plant sterols may be beneficial. Walnuts, high in polyunsaturated fatty acids, have been shown to positively impact serum lipid levels. Almonds, pistachios and other nuts have shown similar results. Those consuming nuts more than four times per week showed the most significant improvement. Also, those with moderately high LDL who drank green tea once to twice per day while following a low-fat diet found more improvement in LDL reduction than they did with a placebo. Moderate alcohol consumption (1-2 drinks per day) has been shown to improve HDL levels. Red wine has the added antioxidant benefit even in its non-alcohol form.
Fat cells secrete chemicals that negatively affect lipid metabolism. “Maintaining a body that is slim and trim with consistent exercise and a low-calorie diet limited in saturated fats is the key”
While the internet is littered with information on thousands of supplements claiming to lower cholesterol and provide other life enhancing outcomes, few are proven effective. Of these, only fish oil, taken in concentrated high doses (> 6g/day) has been proven to lower triglycerides and LDL.
Multivitamins, soy proteins, and other grain products, while not cholesterol reducing, are valuable to many. But when it comes to reducing cholesterol, garlic, policosanol, Vitamin E, and isoflavone supplements have failed the scrutiny of scientific research. Plant sterols such as BenecolR sisosterol and campesterol, found in Promise activTM, have been shown to slightly reduce serum cholesterol levels; however, no studies have demonstrated their ability to lower the incidence of CAD. In fact, the Nutrition Committee of the American Heart Association has suggested that the general population not use these products until further studies determine their safety and efficacy, due in part to potential side effects.

Lifestyle Medicine, is not just a fad or buzzword that is overused in a plethora of health, fitness and wellness magazines, but is actually a medical specialty. It is the practice of using diet and exercise, along with other lifestyle modifications to prevent and manage disease. Lifestyle Medicine focuses on six pillars: healthy eating, physical activity, restorative sleep, stress management, positive social connections, and avoidance of risky substances.
The American College of Lifestyle Medicine was established in 2004. Since then, its membership and outreach have grown exponentially. Lifestyle medicine is currently the fastest-growing specialty in medicine. Its primary aim is to utilize evidence-based therapeutic lifestyle interventions to prevent/control chronic diseases such as cardiovascular disease, type II diabetes, and obesity. However, new data is emerging which expands the role of Lifestyle Medicine into many other areas, including chronic low back pain, sleep, hormonal disorders, Alzheimer’s Disease, chronic inflammatory conditions, and mental health, to name a few.
Lifestyle Medicine differs from conventional medicine in that its approach is not disease specific. Following the six pillars of Lifestyle medicine improves overall health. Conventional medicine targets and treats a specific disease process with medication or surgical intervention in a reactionary approach. Lifestyle medicine prevents or reverses the disease process through behavioral and dietary changes. In a perfect world, Lifestyle medicine and Conventional medicine can be combined to achieve the best results for some patients.
A JAMA study, published in 1993, linked unhealthy lifestyles with premature death. Since this study was published, the rates of cardiovascular disease and Type II diabetes have continued to climb. Obesity rates are at an epidemic level. 70% of American adults, and 22% of children fall into overweight/obese Body Mass Index (BMI) categories. According to the American Academy of Cardiology, only 6.8% of adult Americans meet the criteria for ideal cardiometabolic health, something the Academy calls a “Population Level Code Blue.”
In 2020, the American Heart Association issued a Presidential Advisory for 2030 Impact Goals. The overall goal is to improve morbidity and mortality through preventative measures. Interventions should be targeted earlier in childhood and young adulthood, where healthy habits can be formed with greater success and maximum outcomes. For example, physical activity is well established for its positive effects on cardiovascular health. Physical activity prevents clot and plaque build-up, is antiarrhythmic, and provides hemodynamic stability. Physical activity has also been shown to have psychological, emotional, and social benefits. The American Heart Association categorizes physical activity as a Level 1 (highest) intervention for primary prevention.
Lifestyle Medicine is rooted in evidence-based findings, and its efficacy is supported in scientific literature. A study published in the New England Journal of Medicine in 2002 examined the prevention of the onset of Type II Diabetes in prediabetic patients. Patients were divided into three groups: a placebo group, a metformin group (a type 2 diabetes medication), and a lifestyle intervention group. The metformin group received daily metformin (medication intervention). The lifestyle intervention group received education and prescriptive interventions/instructions on diet, exercise, and stress reduction. Patients were followed for three years. At the end of the study period, the metformin group saw a 31% incidence reduction of type II diabetes, and the lifestyle intervention group saw a 58% incidence reduction in type II diabetes (almost double that of the medication group).
Many examples abound, highlighting the ability of lifestyle medicine interventions for healthy outcomes. The advantages of lifestyle medicine over conventional medicine interventions are numerous. Medications come with side effects. Medication costs are rising and are often not fully covered by insurance programs. Often, current medications are not completely effective for treating disease. For example, Alzheimer’s Disease treatments are lacking. The Alzheimer’s Association International Conference emphasizes healthy lifestyle interventions. They stress adopting 4 or 5 healthy lifestyle factors to reduce the risk of Alzheimer’s dementia by 60%.
Healthy eating habits do not lead to serious side effects. Lifestyle interventions are within the patients’ control and may result in cost savings, potentially lowering food and medical bills. Because lifestyle intervention involves behavioral changes, the process requires time and effort, as well as investment in education and reinforcement to sustain healthy patterns. Motivating clients to make necessary changes and stick with those changes can be the biggest challenge. A Lifestyle/Wellness Coach may be employed to start the client on their journey. The coach works with the client to make choices that are adaptable to the client while fitting within the six pillars. The role of the coach is to hold space and provide guidance for the client, but not to “fix”, “rescue,” or “judge”. Coaching sessions last 30-60 minutes. Coaches and clients may meet 10 times over 3-12 months to establish patterns.
If you, like so many others, have not achieved your health and wellness goals using traditional methods, it may be worth considering Lifestyle Medicine. Focus on healthy eating (minimizing processed foods and sugar intake), physical activity (minimum 300 minutes per week), restorative sleep (between 7-9 hours per night), stress management (controlling anxiety and depression), positive social connections (consistent interactions with friends) and avoidance of risky substances (alcohol, tobacco/nicotine, illicit drugs) have evidence-based positive outcomes to prevent, manage and reverse chronic diseases.

A health column about sugar for Easter??? Well, maybe this information will be more appropriate next week! For those trying to lose weight or “get in shape” for the “bathing suit season,” a better understanding of the role sugar plays in your diet and overall health may be valuable. You have probably noticed a lot of attention being paid to sugar lately. Many television stars and other celebrities have shared their experiences using a “sugar cleanse” when they need to lose a few pounds and get healthier.
I have had several patients and friends tell me the same thing. For 4-6 weeks these people decide to avoid all refined sugars with the goal of losing weight and improving their health and wellness. Well, what is all the fuss about? Terms like simple sugars and simple carbs, which are purported to be bad, and complex carbs, suggested to be good, are being used ad nauseam. While medical research does not support the value of a short term “sugar cleanse,” it may have value for another reason. For example, it would be very beneficial if one engages in a “sugar cleanse” for the purpose of changing their palate with the hope of developing long term healthy eating habits, especially for those with diabetes…to be implemented AFTER the Easter candy has been consumed!
So, with this in mind, I decided to find the answers to some simple questions about the fuss over sugar. What is a simple sugar? What is a complex sugar? Which sugars are good for you?
Sugars, along with starches and fibers, are one of three types of carbohydrates (also referred to as a carb). A carb is “simple” or “complex,” based on its chemical composition and how it is processed in the body. It gets a little complicated because some foods have both simple and complex carbs. Typically, simple carbs are chemically more “simple” and basic, and therefore they are broken down more easily and serve as a quick source of energy. Some of these carbs are naturally simple (like fruit and milk) while others are processed or refined sugars such as those used in candy, soda and baked goods.
To determine if a food product has good or bad simple sugar, you must also know how much fiber, vitamins and minerals are in the food. A food with a higher sugar content combined with a low fiber, vitamin or mineral content will be worse than a food with the same sugar content but high fiber and vitamins or minerals. For example: a candy bar, which is high in sugar without fiber or vitamins or minerals, is not as healthy as a fresh orange, which contains fiber, vitamins and minerals along with its simple sugar (fructose).
Complex carbs have a more complicated chemical makeup and take more time for the body to break down for use as energy. Therefore, these are considered “good” carbs because they provide a more even distribution of energy for the body to use during activity. They cause a more consistent and gradual release of sugar into the blood stream (as opposed to peaks and valleys caused by simple carbs) and provide energy to function throughout the day. Additionally, “good” carbs have the added benefit of providing vitamins, fiber, and minerals that are missing from simple carbs.
Remember that carbohydrates fuel the body and are an important source of energy, especially for active and athletic people. However, carefully selecting the type of carb you eat is critical to peak function and performance.
Simple carbs taste great (according to our modern brain raised on simple sugars) and are easy to break down into a quick source of energy. However, the sensation of hunger is quick to return because the sugar is released and used up in the body quickly, giving the sensation of needing more.
Simple carbs are often “refined” and therefore stripped of their fiber, vitamins and minerals, which is why they are often referred to as “empty” calories.
Simple carbs lead to rapid spikes in blood sugar and insulin levels after meals. When these levels are not controlled over time, it can lead to obesity, which is ultimately related to adult-onset diabetes and high blood pressure.

It’s that time of year…after a long winter of nights that come early and last too long there is LIGHT at the end of the tunnel! In the fall and winter, especially this far north, many people start to feel the gloom of their surroundings creep into their psyche and spring cannot arrive too soon...Is this normal, or a sign of something more serious?
Seasonal affective disorder, or SAD, is at the far end of a spectrum of seasonal mood changes. The mildest of these, “seasonality”, is a normal response to cyclical changes in weather and light exposure. However, when symptoms like depressed mood, lack of motivation, or a shift to more vegetative daily habits become severe and debilitating, SAD may be the cause. In fact, one study found that SAD affects up to 10% of primary-care patients, and that those with a previous diagnosis of depression are even more at risk. Fortunately, though, there are well established therapies that can help those afflicted with SAD to get through the dark winter months.
The American Psychiatric Association defines SAD as a subtype of either Major Depressive Disorder or Bipolar Disorder, depending on the symptoms. It can consist of episodes that onset during either fall/winter or spring/summer, or have symptoms characteristic of either “major depressive” or “manic” episodes. The vast majority of those with SAD, however, experience a persistent overall depressed mood during the shorter days of fall and winter.
In more serious cases:
If enough of these symptoms are present for a long enough time and onset in a seasonal pattern, that can mean Seasonal Affective Disorder. Most people with the disorder find themselves sleeping more and eating more (especially carbs), and report that their symptoms can even resolve with relocation to a sunnier environment. Along the spectrum of disease is a less severe form called “subsyndromal” SAD, which can still be effectively treated. Periods of SAD tend to resolve with the coming of spring, but they can be immensely distressing and always deserve medical intervention.
No one knows exactly why Seasonal Affective Disorder happens, but it appears to be associated with decreased exposure to natural light during the fall and winter months. One possible explanation is the “phase-shift” hypothesis. It states that your body’s circadian rhythms, which are regulated by hormones and the brain, become out-of-step with environmental sleep/wake cues as the days shorten. In other words, the light levels around you and your body’s internal clock are telling you two different things about when to sleep. This disruption of circadian rhythms, or “phase-delay”, likely contributes to the symptoms of SAD, although precisely how it induces changes in mood remains unclear.
Another hypothesis for the mechanism underlying SAD involves abnormalities in the activity of serotonin, a neurotransmitter in the brain. Normally, serotonin regulates mood and attention. However, studies have found that people with SAD clear serotonin out of their brains faster, giving the hormone less of a chance to provide a boost in mood.
Current medical treatment of SAD targets the changes in both circadian rhythms and serotonin metabolism. This can be accomplished with light therapy, antidepressant medications or a combination of both.

While I fully expect to be at the “butt end” of many comments for this column, I feel compelled to address this topic at the request of several patients. It seems that many geriatric physical therapists commonly encounter patients that suffer from constipation which limits their participation in rehabilitation. Ironically, research demonstrates that exercise and activity actually help relieve constipation.
The National Digestive Diseases Information Clearinghouse (NDDIC) reports that 3.1 million people in the United States suffer from constipation. The NDDIC further reports that this problem leads to almost 400,000 hospitalizations, 1.4 million visits to emergency rooms, 1 million prescriptions and 121 deaths each year. Constipation is defined by the Ohio University College of Osteopathic Medicine as three or less bowel movements per week. It is also estimated that more than 27 percent of the elderly are affected.
Severe constipation can result in immediate medical attention in some cases due to intestinal obstruction. In addition to infrequent bowel movements, some symptoms include: feeling poorly, weight loss, loss of appetite, abdominal distention and/or pain, and vomiting.
Healthy people must continue to keep active. Get into good exercise habits at a young age and continue through life. Maintaining a consistent schedule of eating and exercise is also helpful. Some simple suggestions for beginning an exercise program for prevention of constipation in the healthy population are:
Depending on your general health and ambulatory status, these endurance exercises may be appropriate for you. Therefore, consider one or two of the following as a good starting point:
IN CONCLUSION: KEEP MOVING YOUR BODY AND YOU WILL KEEP MOVING YOUR BOWELS!
Visit your doctor regularly and listen to your body.
Keep moving, eat healthy foods, exercise regularly, and live long and well!

The number one health and wellness goal shared by most patients is …to lose weight!

82 million adults spend an estimated 28 billion dollars on gym memberships each year! WHY? There are many reasons we exercise. Some people exercise to prevent illnesses such as cardiovascular disease or osteoporosis. Others exercise for mental health and as a stress release; others do it to improve strength, flexibility, and endurance to prepare for a sport. However, the number one reason people exercise is TO LOSE WEIGHT!
When it comes to losing weight, patients have asked me a wide variety of questions over the years. However, certain questions are consistent. “What exercise is the best to burn calories?” “Even though I exercise 2-3 times per week, why can’t I lose weight?” “What is BMR?” “If I eat a Snickers bar, how much exercise do I need to do to burn it off?” “Are there any tools that I can use to help me track my calories and exercise output?”
Have you ever heard people say that they never felt better or burned more calories than they did when they ran? Well, they may be right! The following numbers are based on the average male weighing 150 pounds: running 6 miles per hour will burn 700+ calories (11-12 calories per minute); vigorously skipping with jump rope or fast cycling will do the same; vigorous walking at 4 miles per hour and moderate biking will burn 600+ calories (10 calories per minute). The 400-500 calorie club includes the following activities: slow jogging, swimming, football, basketball, baseball, tennis, skiing, and moderate walking (3.5 miles per hour). Light gardening burns more calories than golfing using a cart (250 vs. 180).
How many times have you heard people say, “It is hard for me to lose weight because I have a slow metabolism?” What does that mean? To explain this in detail you first must understand BMR. BMR is basic metabolic rate. It is the number of calories that your body requires to operate basic body functions that you don’t actively control, such as continuing to breathe, and keeping your cells and organs working each day. The BMR is influenced by age, height, gender, body fat, and fitness level. BMR is inherently different (high or low) in everyone.
While you can’t change your gender or height, you can influence some things to influence your BMR and burn more calories at rest. One, exercise for longer durations, with greater intensity and more frequently. Two, lower body fat by eating less calories, especially fat and carbohydrates in your diet. Simply, eat less calories than you burn! Three, improve your muscle/fat ratio by weight training.
Basic Metabolic Index (BMI):
BMI: < 18.5 = Underweight
BMI: 18.5 – 24.5 = Normal Weight
BMI: 25. - 29.9 = Overweight
BMI: >30. = Obestiy
For example, I am a 66-year-old male, weighing 155 pounds at 5 feet 8 inches tall with a BMI of 23.6

Daily Calorie Calculator – Find how many calories are in specific foods and what you need to do to lose or gain weight.
So, remember, the number one reason we exercise is TO LOSE WEIGHT! But depending on exercise alone to lose weight is an exercise in futility. Losing weight is an intelligent and consistent combination of a balanced diet with portion control, proper nutrition, adequate exercise and activity grounded in lifestyle changes.
