What's New... U.S. Dietary Guidelines for Americans
- Written by Christine Wolniewicz MS, RD, CDCES, CDN
Every five years, the U.S. Department of Agriculture and the Department of Health and Human Services released the U.S. Dietary Guidelines for Americans. The Dietary guidelines are science-based guidelines offering advice on healthy eating patterns and recommendations for the general population.
The 2020-2025 guidelines are the first set to include a recommendation for babies, toddlers, and pregnant and lactating women. These are referred to as “life stages,” establishing each “life stage” age group should be consuming different diets. For instance, one recommendation for children under two years old emphasized this age group should not be consuming added sugar.
Although there were some updates in the most recent guidelines, many recommendations did not change, leading to controversy. Despite recommendations from the scientific advisory board, sugar and alcohol intake remained the same. Experts did advise that just one drink a day was best for both men and women and that added sugars should account for less than 6% of calories.

Protect your heart this winter!
- Written by Brian Riegel, MD
According to a study published in 2015, the number of heart attacks recorded during the coldest months of the year was 31% higher compared with the warmest months. Numbers were higher in those with underlying cardiac conditions or age greater than 65 and were highest on days where the temperature was below freezing. Another study reported a 19% increased risk of stroke during winter months related to the development of atrial fibrillation which is an irregular heart rhythm.
Why is our risk higher in winter?
Well, the effects of cold temperature on the body result in vasoconstriction, that is, the blood vessels clamp down which results in increased heart rates and blood pressure. The laws of supply and demand are in play. The longer the exposure, the higher the risk. Add to this if there is any overexertion such as shoveling snow or trying to walk faster in windy or snowy weather, or if we are not dressed warm enough. Another important factor is the higher incidence of flu and respiratory infections in colder months, particularly this year with the coronavirus pandemic.
What can we all do to lower our risk?
First, we should reduce our time of exposure as much as possible. Dress appropriately and layer clothing, but don’t over layer as this can lead to overheating which also can be harmful. Avoid shoveling snow if you have any underlying cardiac condition or other medical problems. Take breaks as appropriate if digging out your car from the snow. Absolutely get the flu shot. Soon the COVID vaccine will also be rolling out. Wash your hands and wear masks to reduce our infection risk. Refill your prescriptions on time, don’t let them run out because you didn’t want to leave the house.
Know the Signs.
Finally, we should all know the potential warning signs of a heart attack - which could include chest pain or pressure, discomfort in the arms, upper back or jaw, often accompanied by nausea, sweating or shortness of breath. If any of these, seek medical attention immediately.
Let’s all stay warm and healthy this winter!
Why Do My Legs Hurt
- Written by Dr. Chohan
Many people often complain of leg pain that is accompanied by leg swelling, heaviness, cramping, itching, varicose veins, skin discoloration, hair loss, and/or ulceration. Some people will experience pain at rest or pain with activity. Disease states that are responsible for these symptoms are related to disorders of the arteries and veins of the legs.
Deep Vein Thrombosis
Blood clots in the leg, also called Deep Vein Thrombosis (DVT), can form in the lower leg, thigh or pelvis. DVT is caused by prolonged rest or travel, family history, obesity, pregnancy, blood disorders, and cancer. When clots form they block the flow of blood from the lower extremity back to the heart. This produces leg swelling and heaviness which then leads to leg pain, warmth, and redness. These blood clots can travel from the leg to the lung and cause blood clots trapped in the pulmonary arteries, called a Pulmonary Embolism (PE) producing shortness of breath and chest pain. This can be life threatening and must be treated emergently. Call 911 if you think you may be suffering from a PE. Untreated DVT can also cause post-thrombotic syndrome (PTS) which results when DVT causes long-term damage to the valves in the veins. Symptoms of PTS include pain, swelling, discoloration, scaling of the skin and ulcers. In some cases, PTS can lead to permanent disability.
Treatment for DVT includes blood thinners and minimally invasive surgery. If medication doesn’t work or symptoms are too severe minimally invasive surgery using advanced medical technology can rapidly remove the blood clot from the veins restoring blood flow, resolve the symptoms, and prevent PE and PTS. The goal of treatment is the rapid relief of symptoms and improvement in the quality of life.
DVT prevention is also critical. The best thing you can do is keep mobile and hydrated during times of rest. Squeezing your calves or flexing your calves and wearing compression stockings can keep blood flow moving. Stay hydrated, make sure you drink at least four 16 oz bottles of water a day. This will keep your blood thin.
Veins that can no longer return the blood back to the heart are called insufficient. This can be caused by prolonged standing or sitting, previous DVT, family history, and obesity. Veins have one-way valves that direct the flow back to the heart. When these veins become damaged, like from DVT or from prolonged standing, they can no longer direct flow back to the heart, and the blood pools in the feet and ankles resulting in leg pain at rest, leg swelling, heaviness, and varicose veins. When this goes on for too long it can result in skin discoloration, skin thickening and ulcerations. Sometimes small blood clots form in the varicose veins causing inflammation and pain. In some cases, this can lead to permanent disability.
Treatment of Venous Insufficiency is done using compression stockings and minimally invasive techniques using a small catheter to close the diseased vein by using heat or glue. This a rapid and efficient treatment that will reroute blood from your legs to your heart using healthy veins significantly improving your symptoms.
Venous Insufficiency prevention is critical. The best thing you can do is wear compression stockings if you are in jobs that require prolonged standing, prolonged sitting, intense labor, or lifting heavyweight. Take a rest when you can!
Peripheral Arterial Disease
Peripheral Arterial Disease (PAD) occurs when the arteries become blocked or narrowed and can no longer deliver their cargo efficiently. Arteries of the leg are the delivery system of nutrients and blood to bone, muscle, and skin. Reduced blood flow can result in leg pain with activity, hair loss, loss of muscle tone, skin discoloration, and ulcerations. PAD is caused by plaque build-up in the artery the narrows the space within the artery and can eventually lead to artery blockage. This plaque buildup can be caused by genetics, family history, diet, smoking, chronic renal disease, coronary artery disease, stroke, and diabetes.
Claudication is a common presenting symptom of PAD. Claudication is described as pain with walking. If you develop muscle cramps and pain after walking short distances it can be a sign of arterial narrowing. Occasionally, the arteries can be blocked rapidly and cause quick onset leg pain that is unbearable called Acute Limb Ischemia. This should be treated emergently. If your leg has suddenly turned blue or pale in color, has lost a pulse, feels numb or overly sensitive call 911.
Critical Limb Ischemia is commonly seen in people that have chronic kidney disease, diabetes, and who smoke cigarettes. The common symptoms are pain at rest, muscle wasting, and ulcerations.
Treatment of PAD is done using medication and minimally invasive surgery with catheters to restore the normal size of the artery to return normal blood flow to the leg. Medication is used to thin the blood to prevent blood clots and reduce plaque build-up which usually are lifelong medications. In some cases, untreated PAD can lead to permanent disability.
PAD prevention is also very critical. Maintaining a healthy active lifestyle is the best choice you can make. Activity and exercise promote arterial health. A heart-healthy diet or caloric restricted diet is important to keep weight off and prevent plaque build-up. You should not smoke and if you do, I encourage you to quit. There are many support groups and medications that can help you fight the urge and be smoke-free.
