All About Sunscreen

You may have seen sunscreen in the news after a government-funded study found that twelve common active ingredients may be absorbed into the bloodstream. Only six of the studied ingredients are commonly used in the United States: ensulizole, octisalate, homosalate, octocrylene, octinoxate, oxybenzone, and avobenzone. The study’s author noted that just because ingredients get absorbed doesn’t make them harmful or unsafe; we don’t know enough about these ingredients to deem them as such. All this small pilot study tells us is that these ingredients may enter the body in levels greater than previously understood. The American Academy of Dermatology commented that these ingredients have been used for several decades without any reported side effects in people, so it’s not time to ditch your sunscreen supply (unless it’s expired)! We can soon expect sunscreen manufacturers to fund research to fill knowledge [...]

Sit Less, Maximize Your Routine

Excessive sitting—coined “sitting disease”—is linked to over 30 chronic diseases and conditions. By some estimates, sitting too much can harm your health more than smoking! Over a half-dozen studies also report that prolonged sitting (and a low daily step count) can even undo the beneficial effects of exercise. There’s a simple fix that you can start doing today to protect your body from a sedentary lifestyle; find more ways to move! When you get up and move, all parts of your body benefit. Moving more increases blood flow to your brain so you release more feel-good chemicals that increase productivity, improve mood, and reduce fatigue and food cravings. You’ll also move more blood throughout your body, helping recirculate blood that may have pooled in your lower limbs while sitting. Standing will engage your core, activating your abdominal muscles, protecting your [...]

Exercise Your Brain: Play Brain Games

Games like crosswords and Sudoku are increasingly gaining recognition as ways to protect your brain in older age. Although additional research is needed and a causal relationship hasn’t been established, older adults who regularly play number and word games have shown brain function up to a decade younger than their age on memory tests. Just like muscles, you can use or lose brain function! Brain exercise is an important part of a comprehensive wellness program. June is Alzheimer’s and Brain Awareness Month, a time to acknowledge a disease nearly six million Americans live with today. There is no known cure for Alzheimer’s Disease, but there are a few things you can do to reduce your risk. Try following the MIND Diet, an eating pattern rich in nutritious foods that can reduce Alzheimer’s risk by 53% when followed closely. Reaching a [...]

Nutrient Synergy

As Registered Dietitians, “whole foods first” is our philosophy! When it comes to meeting your nutrient needs, eating a diet rich in whole foods (fruits, vegetables, whole grains, legumes, beans, nuts and seeds) is the best approach. Isolated nutrients, such as those found in supplements, don’t appear to have the same beneficial impacts as whole foods. Although we are unsure why whole foods have greater positive effects in the body, recent research suggests there could be a synergistic effect happening between all the nutrients found in that food. Food is a symphony, and no one nutrient plays a solo. A synergistic effect in one or more whole foods occurs when the sum of two or more nutrients creates a potential health benefit. For example, an apple contains many different components—naturally occurring sugars; complex carbohydrates; soluble and insoluble fiber; protein; vitamin [...]

Build to your First 5K

The weather has finally warmed up enough to get back into your walking routine! How will you build on last year’s progress? One option is setting a new goal, like a 5k (or 10k!) event. Although you could always walk a 5k, learning how to run the 3.1-mile distance offers a new and exciting challenge. You may also improve your cardiovascular endurance, boost your self-esteem, and make new connections with runners in your community! Not to mention having an event on the calendar to train for provides additional motivation to stick with your exercise routine. But before getting started, check with your physician to ensure you’re cleared for exercise. When you’re ready, take these steps to build up to running your first 5k. First, pick an event. Choose one that’s about 6-8 weeks away, depending on your fitness level. This [...]

Get a Dose of Nature

Get a Dose of Nature You likely already do things to help cut down on daily stress. Perhaps you meditate for a few minutes each day; practice self-care rituals; or choose to eat a well-balanced diet that promotes sustained energy and mental clarity. But have you ever considered what spending time outdoors can do for you? Think about it; outdoor-living was the only option for our ancestors. Over time, human brains formed an innate connection with nature, one that can be difficult to uphold with indoor-based living. This relatively recent change to living and working indoors comes with apparent advantages, i.e.,  protection from harsh weather, but our brains never abandoned the instinctual desire to connect with nature. This desire to spend time outside can be demonstrated by the mental and physical health benefits that occur when we get in touch [...]

Try a New Food

Everyday Mediterranean You may not be able to relax on the beaches of Crete or watch the sunset in Oía, but you can enjoy the delicious benefits of the Mediterranean right here at home. The Mediterranean diet has been ranked as 2019’s overall best diet by health experts after years of research into its health benefits. The landmark PREDIMED (Prevention with Mediterranean diet) clinical trials reported that a Mediterranean-style eating pattern may lower incidence of major cardiovascular events, like heart attacks, stroke, and death from heart disease by thirty-percent. A 30% risk reduction is as effective as some prescription statin medications! These findings were further strengthened following corrections to participant randomization protocols in 2018. Mediterranean-style eating has also been linked to lower peripheral artery disease risk, healthier body weight and blood sugars, decreased Alzheimer’s disease risk, and decreased risk for [...]

Blood Pressure Break Down

Blood Pressure Break Down One in two American adults has high blood pressure according to guidelines from the American Heart Association and the American College of Cardiology. If you don’t currently have high blood pressure, that’s great! However, ninety-percent of adults in the United States go on to develop high blood pressure, increasing their risk for stroke, heart attack, diabetes, and dementia. But is high blood pressure inevitable? No! Eating the right diet, losing weight, and exercising regularly can help you take control of your blood pressure. Blood pressure is a measure of the cardiac cycle, or the contraction (squeezing) and relaxation (refilling) of the heart’s chambers. Blood exerts pressure on the walls of your arteries, just like water pushes against the walls of a garden hose. The force exerted by blood on the walls of blood vessels during a [...]

Beans for Dessert

Beans for Dessert When it comes to dessert, fruit is always your best option as it’s naturally sweet and offers a healthy dose of fiber, vitamins, minerals, and antioxidants. It is also well established that fruit consumption is linked to lower risk of chronic disease. If you want to stay on track with your healthy diet, improve your biometric screening results and you’re bored with having fruit for dessert, try Dessert Hummus! You’re likely familiar with hummus, the traditional middle eastern chickpea dip that pairs perfectly with crunchy carrots, cucumbers, and celery. Its main ingredient, chickpeas (garbanzo beans), has grown in popularity so much that the United States Department of Agriculture expects crop plantings to reach record highs in 2019. This trend reflects our newfound love for all things chickpea! Put off by the idea of beans for dessert? We [...]

April is National Volunteer Month

National Volunteer Month April is National Volunteer Month, but volunteer work any time of year is important for the health of both you and your community! Nearly one in three American adults (77 million!) volunteer each year, contributing a collective 6.9 billion hours of service at an estimated value of $167 billion. But did you know that helping others could help you too? Helping your community is what matters most, but when performed altruistically, volunteering has mental and physical health benefits for volunteers themselves. Research has shown positive associations between volunteering and improved health in older age demonstrated by longer lifespan, higher cognitive function, and lower rates of depression. It’s hypothesized that knowing your actions make a lasting impact on those you serve helps you feel better about yourself, thus reducing stress. Volunteering can also offer a new sense of [...]
