Credit: iStock Protein is the building block for all the muscles in our body. We rely on protein to maintain structural support and aid in nearly all cellular processes. Our muscles are necessary for breathing, walking and balance, all of which allow us to maintain our normal activities. Loss of muscle mass (called sarcopenia) is … Continue reading Why Do You Need Protein (And How Much) In Menopause?

The Brain-boosting Power of Strength Training
Credit: iStock/Zorica Nastasic As the population ages, Alzheimer's disease and related dementias and other neurodegenerative diseases are on the rise. These conditions can make independence harder, but exercise can protect your brain. Aerobic exercises such as walking, jogging and bicycling can improve brain health, size and function. Research has shown that strength training may offer … Continue reading The Brain-boosting Power of Strength Training
How Black Pepper Spices Up Your Muscle Power
Credit: iStock/ayala_studio The primary function of skeletal muscle is to move our limbs. These muscles are attached to our bones and pull on them during contraction. When contracting, muscles consume energy—like a Ford Mustang using fuel to generate propulsion. Like teeth, we only get one set of muscles, so we need to take care of … Continue reading How Black Pepper Spices Up Your Muscle Power
From Tomatoes to Treadmills: What Scientists Are Discovering About Everyday Health
American Physiology Summit attendees view scientific posters. Credit: Erica Roth From record-breaking running speeds set by a 91-year-old to how your body responds to climate shifts, the American Physiology Summit brought together researchers exploring the science of health and life itself. Here’s how their findings presented at the annual meeting of the American Physiological Society could … Continue reading From Tomatoes to Treadmills: What Scientists Are Discovering About Everyday Health
Keeping Older Adults Hydrated in the Heat
Credit: iStock/Yau Ming Low Most of us know it’s important to drink more when it’s hot outside, especially when we’ve been physically active. Without replacing the fluids we lose through sweating, we can start to show signs of heat-related illness, such as lightheadedness and muscle cramping. Dehydration also strains the heart and kidneys. This advice … Continue reading Keeping Older Adults Hydrated in the Heat
What and When We Eat May Be the Key to a Longer Life
Credit: iStock Age-related diseases—including cardiovascular disease, cancer and diabetes—are a growing problem worldwide as people live longer lives. Promoting healthy aging is important, but the best intervention for healthy aging identified so far—eating fewer calories (calorie restriction)—is often too difficult for people to follow. A potential alternative lies in the growing realization that “a calorie … Continue reading What and When We Eat May Be the Key to a Longer Life
Small but Mighty: How Telomeres Could Control Vascular Aging
Credit: iStock As we get older, our cardiovascular system changes dramatically. Specifically, our blood vessels become stiffer and lose some of their ability to relax. This is known as endothelial dysfunction. Scientists debate and propose many theories about the specific causes of endothelial dysfunction with aging. Recently, telomeres have become a hot research topic. Telomeres … Continue reading Small but Mighty: How Telomeres Could Control Vascular Aging
The Key to Reversing Aging: Folded Mitochondria?
Credit: iStock Getting older is a fact of life. As we age, we can grow bigger, smarter and stronger. But at a certain point, our bodies often start to slow down. The idea behind why we age and why our bodies slow down is that we start to lose the ability to make enough energy … Continue reading The Key to Reversing Aging: Folded Mitochondria?
Getting Younger As We Age: Could a Diabetes Drug Help?
Between the years of 1946 and 1964, families in the U.S. were having a lot of children—76 million to be exact. People who were born in this time period are generally referred to as “baby boomers.” Today, the oldest baby boomers are over the age of 70, with all baby boomers turning 65 or older … Continue reading Getting Younger As We Age: Could a Diabetes Drug Help?
Did You Know?: A Muscle May Increase Pneumonia in Older People
By the year 2030, an estimated 70 million people in the U.S.—about 20 percent of the total population—will be older than 65. Going forward, this number is only expected to rise due to a combination of declining birth rates and increased life expectancy. A well-known witticism is “Age is an issue of mind over matter. … Continue reading Did You Know?: A Muscle May Increase Pneumonia in Older People
