Patients often tell me that they would like to exercise but hesitate due to their knee or hip pain. They want to know what type of exercise is best for those suffering from osteoarthritis (OA). Osteoarthritis is also known as degenerative arthritis. It is the most common form of arthritis in the knee. Osteoarthritis is usually a gradual, slow and progressive process of “wear and tear” to the cartilage in the joint which eventually wears down to the bony joint surface. It is most often found in middle-aged and older people and in weight bearing joints such as the hip, knee and ankle. It causes gradual onset of pain, swelling and stiffness in the involved joint, especially after increased activity and weakness with loss of function due to disuse.
However, OA is not an excuse to avoid exercise, but it is important to be smart about it. Regular exercise is essential to maintain a normal lifestyle for those with OA. However, if you do the wrong exercise, use poor technique, or are too aggressive, you could flare up your joints and do more harm than good.
When performed correctly, exercise for those with Osteoarthritis has many benefits:

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.

I have invited Gretchen Welby, PharmD, MHA to present the current wisdom on the very controversial topic of vaccination/immunization to raise awareness and dispel any myths and misunderstandings.
Scientific progress has rarely advanced by popular vote, and vaccination is no exception. While public sentiment deserves respect and thoughtful engagement, the evidence guiding immunization policy is built on decades of rigorous research, transparent testing and continuous review. These research processes are designed precisely to rise above fear, trend, politics or misinformation. Choosing to prioritize scientific findings over shifting opinion is not an act of dismissal, but of responsibility…it is a commitment to decisions that protect both individual lives and the collective good, even when those decisions challenge what feels comfortable or widely believed.
2024 marked the 50th anniversary of the World Health Organization’s Expanded Programme on Immunization (EPI). An initiative to make life-saving vaccines available to all worldwide. A modeling study done to mark the 50 years of EPI estimated that vaccination averted 154 million deaths, including 146 million deaths among children. Several additional studies on vaccine effectiveness show that vaccines improve infant safety, contribute to a healthy society, and even reduce cancer risk. Vaccines work for an individual and society. The data show that many vaccines can reduce mortality by 99% or more. Unfortunately, global immunization has been a victim of its own success because people have forgotten how deadly and dangerous the diseases vaccines protect against can be.
Vaccine effectiveness is overshadowed today by misinformation about vaccine safety, changing vaccine administration timelines, and mixed public health messaging. What are the outcomes of the recent relaxed vaccine message? The number of measles cases has jumped. Fifty-nine cases were reported in 2023. In 2025, 2242 cases were reported. For additional perspective, an article published in the 2007 edition of JAMA listed the number of deaths pre-vaccine release and the number of deaths post-vaccine release. The findings are remarkable.
The recent Centers for Disease Control and Prevention (CDC) change to the childhood vaccine schedule reduces routine protection against 13 childhood diseases to 7, with shared decision-making now required for the remaining 6. Diphtheria, tetanus, acellular pertussis (DTaP; Tdap), Haemophilus influenzae type b (Hib), Pneumococcal (PCV), Inactivated poliovirus (IPV), Measles, mumps, rubella (MMR), Varicella (VAR), and Human papillomavirus (HPV – changing from 2 doses to 1 dose) are now part of the routine vaccine schedule.
Rotavirus, COVID-19, Influenza, Hepatitis A, Hepatitis B, Meningococcal ACWY, and Meningococcal B are now grouped in a shared-decision-making model. Traditionally, when changes are made to the vaccine schedule, they are made with much deliberation, study, and expert input from multiple agencies and governing bodies. However, this recent change, however, did not follow the normal study path. This is concerning because changes are proposed without proper study of the immediate and long-term consequences.
Vaccines have been shown to be safe, with most patients experiencing very minor side effects. Normal reactions from vaccinations include low-grade fever for 24-48 hours. A low-grade fever and minor muscle aches signal the body's immune response. Tenderness and redness at the injection site are other normal reactions from immunization and should last from 24-48 hours. There is no proof that thimerosal (a preservative historically used in vaccines) causes adverse reactions. Additionally, thimerosal has been removed from most vaccine preparations used today. Vaccines do not overwhelm a child’s immune system. Children are exposed to hundreds of antigens daily. A WHOLE pediatric vaccination schedule exposes them to around 50 antigens. There is NO evidence to support altering or delaying the American Academy of Pediatrics vaccination schedule. This does NOT increase safety; it DECREASES protection at a time when infants and children are most vulnerable.
How can consumers of healthcare information, in particular, vaccine information, find reliable, trustworthy, educated guidance? Since the June 2025 changes in CDC personnel have resulted in less qualified members of the Advisory Committee on Immunization Practices (ACIP), it is generally best to rely on non-governmental sources such as the American Academy of Pediatrics, American College of Gynecologists, the Infectious Disease Society of America, and the Vaccine Integrity Project for vaccine advice. Additionally, discuss vaccine efficacy and safety with your doctor.

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.

According to the Centers for Disease Control and Prevention (CDC), the 2025/26 flu season has been exceptional. Normally, elderly adults have the largest number of flu related hospitalizations while young children are second. This year, however, baby boomers between 50 and 64 years of age are the second most vulnerable. And, as of January 2026, the US flu season has resulted in an estimated 19 million illnesses, 250,000 hospitalizations, and 10,000 deaths. At the risk of creating an overreaction and promoting “germaphobic” behavior, if there is one time of year that diligent hygiene has merit, it is now…during flu season.
Contracting the cold or flu can make you feel run-down and under the weather for weeks. Unfortunately, your daily activities and responsibilities cannot take a sick day. The common cold and flu is most prevalent during late fall, winter and early spring. According to flufacts.com, “The influenza virus, more commonly known as the flu, is defined as a contagious respiratory infection that infects the nose, throat, and lungs. Thankfully, there are several easy and effective preventive measures that can reduce the probability of contracting the cold and flu. These preventive measures are designed to help keep your immune system strong and healthy. A healthy immune system fights against pathogens, such as the cold and flu virus. This article will focus on the ten best ways to prevent the flu and cold this season.

Patients often tell me that they would like to exercise but hesitate due to their knee or hip pain. They want to know what they should avoid, how to prevent and what is recommended to prevent or limit the progression of arthritis. Osteoarthritis (OA) is also known as degenerative arthritis. It is the most common form of arthritis in the knee. OA is usually a gradual, slow and progressive process of “wear and tear” to the cartilage in the joint which eventually wears down to the bony joint surface.
It is most often found in middle-aged and older people and in weight bearing joints such as the hip, knee and ankle. It causes gradual onset of pain, swelling and stiffness in the joint involved, especially after increased activity. While diet and exercise help, some people are more likely to develop OA based on previous trauma or injury, labor intensive occupations and genetics. Either way, we all get OA to some degree but there are a few things you can do to limit wear and tear to your joints.
However, OA is not an excuse to avoid exercise, but it is important to be smart about it. Regular exercise is essential to maintain a normal lifestyle for those with OA. However, if you make poor lifestyle choices, do the wrong exercise, use poor technique, or are too aggressive, you could flare-up your joints and do more harm than good.

It is no surprise that the most common New Year Resolution is to be healthier…eat less, exercise more, etc. However, health is multidimensional! To be truly healthy, one must have a healthy mind, body and spirit! It is well documented and established that exercise and diet contribute to your physical health, and mentally, the brain is healthier by avoiding toxins such as tobacco, drugs and alcohol, while the spirit is healthier by being mindful, spiritual and meditative. Unfortunately, less attention is paid to other critically important aspects of health: the unhealthy impact of negative visceral emotions such as hate, jealousy, and anger.
Considering our present divisive social and political climate in the United States and globally, I find myself in constant search to understand the pervasive hate and division which seems to be, not only prevalent, but acceptable. I have attempted to read books such as “The Science of Hate,” by Matthew Williams, about the science of hate and survival, “Demon Copperhead,” by Barbara Kingsolver, about those marginalized and left behind, ”The Demon of Unrest,” by Erik Larson, about the history of our national political division preceding the Civil War and its relevance in the present, and watch TED Talks podcasts and television specials such as those presented by WVIA Public Media in a special series “We Stand Against Hate.”
All of this, to no avail! I failed in my effort to understand the unthinkable: We hate individuals whom we have NEVER even met. We hate groups of people through unfounded generalizations. We hate because of color, creed, stature, rank?!?! At the end of the day, I just don’t get it! Fortunately, I was not born with the “hate gene” and may never fully understand. But what I do understand is that HATE IS UNHEALTHY! So, if you want to be truly and completely healthy this new year, work on your hate!
The word “hate” is thrown around more often than the actual emotion is felt. The statement “I hate broccoli” is rarely accompanied by the strong negative emotion of true hatred. Even strong feelings of anger or disgust are not the same as hate. According to Laura Williams, clinical psychologist “Hate is a profoundly intense and enduring dislike for someone or something. Hate can be tenacious, and often has roots in mistrust, fear, or (lack of) individual power, and vulnerability.”
It can be hard to distinguish hate from other powerful negative emotions that you may be feeling at the same time. Some psychologists say what makes hate different is that it’s directed toward who or what someone or something is, rather than what they’ve done.
The negative physiological, physical health, mental and emotional effects of hate are well documented by many sources including the National Institutes of Health.
Ultimately, hate creates an internal state of emergency which demands significant physical and mental resources and leads to wear-and-tear on your entire system. Letting go of hate is a form of self-care that promotes relaxation and long-term well-being.
2026 is a great opportunity to be truly healthy…eat well, exercise more and rid yourself of hate!
