Baby boomers have been a very physically active generation to the extent that many joints have been wearing out, and are needing to be replaced. Joint replacement is a major operation, and recovery takes a while, but the dream is that the pain will be gone and we will be able to return to more activity without pain. Our quality of life will improve.
After recovery and rehabilitation the…

Will spring please soon come and melt away the winter. The winter did give us many day of snow shoveling exercise, but otherwise we mostly want to curl up in our favorite chair and sit out the winter.
This is very dangerous!
There have been many studies in recent years revealing the dangers of too much sitting. A very large Sax Institute study of people 45 and older found that…

What fun we are having this winter! Well, maybe not.
Since January 19, Portland has been covered with about 80 inches of snow. It has been relentless.
The negative viewpoint of this constant snowfall is limitless, and does not have to be repeated. But, what about the positives?
The contrast of the white snow and dark trees can be very beautiful. Well, the storms closed down…

Fall is here. The leaves on trees and bushes are richly colored.

It is June. Warm weather is here. Your body needs much more hydration than during the cold winter.
Your body has more water than any other substance, and it is the most important. Without water humans can only survive a few days, because water regulates body temperature, transports nutrients and oxygen to cells, keeps body tissues moist, protects organs, lubricates joints, and helps…

There is a modern day disease, which does not yet have an official medical phrase, but which causes a long list of serious ailments. This disease can be called "sitting disease." Prolonged sitting is a symptom of the moderm work and home lives of many people. Physical labor has maintained only a very small part of the modern world.
Extended sitting contributes to many health…

"Older adults" typically refers to anyone age 65 years or older, but it is important to realize that this age group includes a wide range of fitness and health. Age-related physiological changes result in declines in functional capacity that can impact activities of daily living. These physiological changes start at about 30 years old, and continue until end-of-life. Physical activity levels…
Saturday, Mar 22, 2014
More than one third of adults and 17% of children (2-19 years of age) in the United States are obese. More than half of adults do not meet the Physical Activity Guidelines for aerobic physical activity, and the prevalence of aerobic physical activity declines with increasing age.
With these realities in mind, finding ways to encourage more physical activity is of paramount importance to…

Winter seems to never end this year. How long will it take to melt all this snow, if and when it actually warms up? How many more months will it be before we can start burning extra calories with our normal spring outdoor activities. We just cannot be physically active enough during the winter to burn enough calories to avoid adding a few pounds of unwanted fat to our bodies. We go to the Y for…

It has been a very cold winter. Nothing starts a cold winter day better than a steaming bowl of hot cereal. Besides warming and filling you up, hot cereal gives you plenty of reasons to feel good about what your eating It's packed with fiber, protein, vitamins, and minerals, and pouring low-fat or fat-free milk over your cereal adds still more protein, calcium and vitamin D. If you also top…

The weather has been cold with not much snow, until today, to prevent us from going to the Y for our calorie burning exercise. The Superbowl with it excesses is in our past. It is time to focus the mind on three more ideas to work on to metabolize more calories.
1. Cutback on sugar. The average American consumes almost 152 pounds of sugar a year! This equals about 13 teaspoons per day…

January, 2014, has been snowy, icy, and cold. Due to all these problems it has been difficult to even participate in normal outdoor activities like running, walking, biking, snowshoeing, hiking, and cross-country skiing. During the winter it is just more difficult to be as physically active as during the other seasons.
Consequently, we end up sitting more and exercising less, which…

If a miracle ingredient found in many tasty, inexpensive foods helped you lose weight, live longer, and avoid dangerous diseases, would you eat it every day?
No, I am not trying to sell you a bridge in Brooklyn. There really is such a food ingredient, dietary fiber. Dietary fiber is easily available, but most of us eat way too little of it, putting ourselves at increased risk for heart…

It is cold and snowy outside. Cold and flu bugs love this time of year. Our doors and windows are sealed. Everyone stays indoors most of the time. The bugs can easily visit many people.
We constantly wash our hands and try to stay far away from coughing people. But, it is still impossible to avoid the cold and flu bugs. We know our bodies will be exposed to the nasty bugs no…

The Thanksgiving, Hanukkah, and Christmas holidays have arrived for 2013. These holidays are wonderful times to renew and grow relationships with friends and family. They are also holidays to celebrate food.
The holidays can also be a time of stress with our relationships with friends and family and with food.
Mindfulness can be the pathway to reduce the stress and increase the…

It is the beginning of cold and flu season. We constantly wash our hands and stay far away from people who are sneezing. We try to avoid touching commonly used door handles.
These tactics help us avoid exposure to cold germs, but are there ways to improve our immunity to fight cold germs that do manage to invade our bodies?
Most research has confirmed that moderate exercise, such…

Would you like to lose about 8 pounds over the next year? Then run 10 marathons. Running 10 marathons will burn about 30,000 calories, which is equivalent to about 8.5 pounds of fat.
Eight pounds of weight loss might be appealing, but running 10 marathons in one year? No way!
How about if you could just stand around every day and still burn those same 30,000 calories. Now that…

Exercise is as effective as drugs at preventing diabetes and repeat heart attacks, and it is potentially better than medication for averting additional strokes.
This is the essential result of a study recently published in the British medical journal BMJ. The study was related specifically to four health conditions--Type 2 diabetes, repeat heart attacks, repeat strokes, and heart…

As nutty as it seems, eating a handful of fatty, high calorie tree nuts every day could actually ward off an expanding waistline. It could also boost your heart health and lower your risk of several diseases, according to several recent studies.
One study, published in the Journal of the American College of Nutrition, found that the participants in the study who ate at least one-quarter…

We are constantly reminded that healthy eating and exercise are necessary for a healthy heart. Of course, healthy eating and exercise take discipline and work, which is hard and time consuming.
Why can't something like music be healthy for our heart, as well as entertain us. Well, it is!

I love walking around the Y and seeing all the members active with their favorite exercise programs: swimming, cardio, strength training, group exercise classes, basketball in the gym, talking with friends, children in the the child care area. The members are all ages from very young to quite old. They all seem to be having a very fun time with their healthy exercise.

Now that you have taken my advice and have boosted your brain health and memory by mentally focusing and engaging your brain while you exercise, you now need to protect your healthy brain. No, a helmet will not work except when you are riding a bike.
To protect your brain you need more fat and less fat. Now, that sounds confusing. The key is what kind of fat.
Smart fat choices…

There is plenty of research that shows that at any age, physical exercise boosts brain health and memory. Recent scientific evidence has found that to get the best cognitive benefits, you need to be mentally focused and engaged during your workouts.

If you wear headphones or watch TV while you exercise, you could be…

Summer arrived with some 90 degree, sunny days, though since then we have seen mostly rain and clouds. The sun will return along with the need for sunscreen to protect our largest and most visible bodily organ, our skin.

The summer season is finally here again, though you may not have noticed over the past few cloudy weeks.
We love the sun. Maine is vacationland, and lots of sunshine is essential to our summer economy. Maine has long winters, and we Mainers need summer sun to prepare for the next one. Mainers are gardeners, and our gardens need sunlight.
But, our skin should not have too much sun…

May is a great time of the year for runners to head outdoors to run. The weather is cool and sunny. Life is bursting out with flowers, leaves, and green grass.
Runners love spring, but runners love to run any time of the year. Why?
Running is not easy. In fact, it is very hard, it hurts, it's very tiring. It is hard on the muscles and tendons. It abuses the ankle, knee, and hip…

As you start to approach the age of 40, are you concerned with crow's feet and wrinkles around you eyes?
Since May is Healthy Vision Month, it is a good time to think about what starts to happen to your eyes as you see your 40th birthday ahead. By the age of 40, many people may begin coping with vision problems they did not have before. These problems often include dry eyes and…

We drink coffee to help wake us up, and help keep us awake all day. We do not drink coffee to help us sleep.
Yet, research has found that drinking 2-3 cups of coffee a day and sleeping eight hours every night help us live longer. How does this work?
Over the past years you may have often heard that multiple cups of coffee a day can cause the jitters and thus must be bad for you…

Spring will come! The snow will melt! We will be able to run and walk outside in the fresh air, sunny skies, and beautiful scenery!
We want to be ready. We are bored of the indoor treadmill. The treadmill is a great cardio machine to keep our cardiovascular system in good shape. But, it is different than running or walking on the hard ground. It does not give our bones, joints, and…

February is the month when we wait out winter. It can bring us wintry storms like last Friday and Saturday, but we know that in a few weeks March will be here with its bright, melting sun.

Did you resolve to increase you wealth during 2013? Last week I quoted Virgil: "The greatest wealth is health." The best New Year's resolution to increase wealth would be to improve health.
We are individuals. Our life is our greatest possession. Only we alone can truly feel our pain and pleasure. Other individuals may ask us questions and give us advice, but only we alone can make the…

Another new year is on our mind. Do we make another New Year's resolution? Did we make one last year? Were we successful upholding last year's resolution, and every year before? Or, did we fail? If we made another one this New Year, would we just fail again? What should we do?
Many centuries ago Virgil said that "The greatest wealth is health."
Have any of our past resolutions…

There has been much coughing, nose blowing, and sore throats this fall. The coughing and nose blowing are a nuisance, but the sore throat hurts.
Many people run to the doctor's office and demand antibiotics for their sore throat, and in a few days their throat feels much better.
The age of antibiotics began in the 1930s with the introduction of sulfa drugs, followed by penicillin…

Nearly everyone I know has had a cold during the past few weeks. The colds have been fairly mild, but colds are still colds. We are a sharing community, and we sure do a great job sharing our cold germs.
As a general rule, adults with a cold will be able to infect others starting one day before symptoms even appear, and up to five days or so after becoming sick. Infants and children are…

Halloween is upon us with all its creative costumes, parties, trick-or-treating, decorating, and jack-o'-lanterns. It is all about just light fun. The jack-o'-lantern is the mainstay year after year, cutting off the top, cleaning out the seeds, carving a face, putting a light inside to glow the carved face in the dark.
But, then what after the fun ends? Do you just throw away the seeds…

For many people one of their favorite fall activities is to go to the county fair. The fair is a reminder of just where our food really comes from.

Middle-age, the 40s and early 50s, are a very busy time what with children in their teen years or college and careers in a very responsible and busy stage.

Or, do you just want a relaxing event to rejuvenate you energy level?
Then, massage you mind and body with a massage.

Common knowledge: a tan comes from ultraviolet radiation, either from the sun or a tanning booth. Ultraviolet radiation certainly gives our skin some reddish color, but along with this reddish skin color comes premature wrinkled skin and a dangerous risk of skin cancer. You may hate the pale skin you keep covered all winter, but do you really want your skin to look old before you are old and…

The summer has been hot, and humid. In my last two blogs I discussed how to stay safe when exercising in the heat. Have you continued to work out with the modifications to your workout and the safety precautions? Or, have you holed up in an air conditioned room whether at work or home, moving as little as possible?
Be careful that this inactivity caused by the heat does not become a…

-Fainting, if you're not…

Eating too much sugar can eat away your brainpower!
A study at the University of California Los Angeles (UCLA) was recently published and showed that a steady diet of high-fructose corn syrup reduced lab rats' memories, but when fed omega-3 fatty acids, the memory loss was reduced.
Before the sugar drinks began, two groups of rats were enrolled in a five-day training sessin in a…

Once blood pressure rises about 139/89 mm Hg, medication is usually necessary to reduce blood pressure to healthy…

While hanging around the Y's Wellness weight training area all day, I see many men doing heavy lifting to build their lean muscle mass. They lift very heavy weights with only a few repetitions, and then they rest for a long period of time. This way they are able to do several sets of these heavy weights. This is a great way to bulk up their muscle size and strength.
The question is…

In the near future, about 10 to 20 years, we are going to have a big shift in our model for health care. To glance into the not-to-distant future you can imagine what it would be like to live robustly to over 100 years without dying of any specific disease, or wasting away with an enfeebling, long-lasting disease.
This will happen with you monitoring and adjusting your own health in real…

Saturday afternoon the Portland Y Wellness Department had a party at Director Debbie Reed's home in Porter, ME. The party included a two mile walk. The pre-winter day was sunny and 48 degrees. The walk was pure pleasure.
It is said that most great thinkers are walkers, as thinking and walking seem to be at the same pace. Life seems so busy that we seem to not have enough time to walk or…

We Americans should be very thankful for the abundance and quality of life that we enjoy. When we do our grocery shopping for Thanksgiving dinner, we should slow down and observe with thanksgiving all the available and healthy food in our large grocery stores.

From your body's point of view, normal aging isn't normal at all. It is a choice you make by the way you live your life. You can control your aging process.
You replace about 1% of your body's cells every day. That means that 1% of your cells are new every day. It is your choice whether these new cells grow strong and are youthful, or decay and are old.
Most aging is programmed…

Does your perception of how hard you exercise influence how much you eat? Do you think that it is okay to eat more calories, because you recently exercised?
An interesting study at Cornell University involved a one mile walk around a lake before being served dinner. The study group was divided in half, and each group had a leader for their walk.
The first group was told by their…

Over your career have your jobs become more and more sedentary? Part of the reason Americans have been gaining so much weight is that our jobs require less activity and more sitting.
In reviewing energy expenditure since 1960, scientists report that men are burning an average 140 fewer daily calories on the job; for women, it's 124 fewer calories a day.
The obesity epidemic has…

Which is more dangerous, dehydration or hyponatremia? Who has even heard of hyponatremia?
It is summer. It is hot! You like to run. You like to do outdoor activities. After all, that is what summer in Maine is all about. You sweat a lot. You see ads everywhere for beverages to purchase to prevent dehydration. If you sweat, you will lose vital nutrients. You could suffer severely…

I am back from vacation. I assume that since it has been a few weeks since Because! #2, you are all actively building stronger muscles and improving your health by lifting weights. Just in case there are still some stragglers, I'll give you four more Because! reasons…

Have you started lifting weights after last week's four good, solid reasons why you should? If yes, great! If not, then I'll try four more reasons that hopefully will persuade you to raise that dumbbell over your head.
#5. Everyone has some stress in their life. Health scientists have found that the fittest people exhibit lower levels of stress hormones than those who were the least…

You know you should exercise. Lose weight. Keep the weight off. It's healthy. Your friends do it. You walk the Back Cove. You walk around the block when it is nice out. You do cardio at the Y. Yet, it's not working the way everyone says it should. You don't look or feel the way you think you should.
Do you lift weights? Well, no. Reasons? Too many confusing machines. Boring. Too many…

Water, water, everywhere ... don't drink too much!
Are you a runner? Do you run road races? Then, you are bombarded with notices and advertisements about the dangers of dehydration and to stay hydrated with water or sports drinks. Sweat will wash out vital nutrients! Drink liquids before, during, and after races to replenish these nutrients!
Don't believe all the hype!

Is your eating choice a pyramid or a plate? After two decades of trying to make us eat off a pyramid, the U.S. Department of Agriculture (USDA) has finally figured out that we really eat off a round plate.
Nobody could easily figure out what the USDA was trying to tell us with their pyramid advice on the most nutritious foods we should be eating and in what proportions. The U.S…

How do you break your fast?
As we sleep, chemicals in our bodies are at work digesting food eaten on the previous evening. By morning, we are ready to "break the fast" after a long night's sleep. The blood sugar (glucose) we need to power our muscles and brain has been depleted by the time we wake up, and breakfast is needed to replenish this power source.
If we miss the early…

A fun activity when you are with a group of friends would be to ask the question: "What personality characteristic was most associated with long life?" It could lead to an interesting conversation with many different ideas presented. But, unless someone had read the book "Longevity Project," probably no one would come up with the correct answer.
I have not read the book "Longevity…

I keep hearing and reading that we use only about 10% of our brain, so we must buy these brain exercises and supplements. The idea that we use only 10% of our brain is a 100% myth.
Brain scans of various kinds have shown we regularly use all of the brain. Dr. Robert H. Shmerling of Beth Israel Deaconess Medical Center in Boston, Mass, states that "some parts of the brain are more…

If you love life and want to hang around for a very long time, there are many lifestyle habits you will want to practice on a regular basis. Some of these healthy habits may be hard and some may be easy, but one of the easiest is to eat more fiber.
An analysis by the National Institutes of Health of many scientific studies on the effects of nutrition on health has found a direct link…

It has taken four months into 2011 for spring to arrive, and it finally did over the past weekend. Out came the gloves, shovel, clippers, rake, and trowels. The day was sunny and warm at least for Maine. My primary job for the day was to chip the branches from the tops of some trees I had cut down during the winter. The branches were on the lawn, so the time-pressure was to clean them off the…

While the nutritional advantages of dark, leafy greens are widely known, not everybody loves spinach as much as Popeye. Branching out to try new types of greens may inspire a previously unrealized appreciation for the wide range of tastes, varieties, and culinary potential within this group.
Chinese broccoli, also known as Chinese kale, or gai lan, is one such leafy green that would be…

Sarcopenia is a pretty fancy word! What does it mean and why am I throwing around such a big word? Because it a word that we should all be concerned with, as it affects all of us.
Sarcopenia means muscle loss with aging. And, aging means starting at about 30 years old! This is a scary thought for nearly all of us, or it should be. Throughout our lives, our bodies are continually breaking…

Would you like to connect in your kitchen with a prehistoric human ancestor from the Neolithic period? Then cook up some lentils, which were domesticated by our early ancestors in about 9500 BCE in the Near East. Lentils continue to play an important role in culinary traditions worldwide, but especially in the Middle East and the Indian subcontinent which have large vegetarian…

Have you felt light headed lately? Possibly your head is lighter than it used to be unless...
The hippocampus is the brain's memory center. As we age, the hippocampus normally loses 1% to 2% of its volume annually, affecting memory and possibly increasing the risk for dementia.
But, there is hope for us all. A study recently published in the Proceedings of the National…

Pumpkin seed might come to mind only when it's time to carve Halloween jack-o-lanterns and they are usually thrown away, but this is a waste of a very nutritious and fun food. Pumpkin, and squash, seeds were a large portion of the diet of Native Americans and early European settlers, and they are still used in many Mexican dishes. So, why throw away such a tasty and nutritious food?

Most of us join the Y to help us be active and to exercise so that we will be healthy and feel good. Sometimes it is difficult to make it to the Y because of snow or rain, too much work, not enough energy, not enough easy parking, just too busy, and so on. It takes effort to get to the Y or walk around Back Cove for an hour of healthy exercise. But just making the effort to sit less, by itself…

If your tongue is still burning from the New Healthy Food #5, try cooling it off with the sweet taste of mango. These honey-sweet, smooth-textured tropical fruits were originally grown in the sub-Himalayan plains of India, but they are now produced in tropical areas all around the world, and are often called "the king of the fruits." Worldwide, mangoes are so popular they're recognized as the…

Recently a young friend of mine slipped on the ice and broke a bone in her foot. This winter has been particularly dangerous with much slippery ice on the streets and sidewalks. Slippery winter ice is dangerous for all of us, but older adults have to be concerned about falling year round.
Falling is the leading cause of injury among seniors, and is the ninth leading cause of…

On my vacation to California and Arizona last week I was excited to be served my New Healthy Food #4, avocados, sliced on a salad and spread in a ham and cheese with lettuce and tomato sandwich. This seemed to be the natural ingredient for my hosts to serve in each setting.
For New Healthy Food #5, let's give our palate a switch from the richly smooth and slightly sweet flavor of…

After a quick trip to Greece for Greek yogurt, let's head back to South and Central America to try avocados. When you first look at these bumpy, green-skinned fruits, it is hard to imagine that inside it contains a slightly sweet flavored and richly smooth interior. Avocados add an intriguing heart-healthy fruit choice to your diet.

So what have you been doing for exercise this winter? Shoveling snow for sure. Everyone agrees that Maine has beautiful summers, but Maine also has a reputation for outdoor recreation in the winter. Mainers have three choices in winter: shovel snow and travel south for a warm vacation, shovel snow then sit around and brood about the nasty, long winter, or shovel snow then stay outdoors to enjoy…

Now that we have tried sardines and quinoa, let's hit the dairy with yogurt, actually Greek yogurt. Yogurt has long been known as an excellent source of bone-building calcium and muscle-building protein. Greek yogurt, however, is a relative newcomer to US households. As with all yogurts, Greek yogurt is produced by heating and culturing milk with gut-friendly bacteria. Greek yogurt is then…

New healthy food #1 was sardines, which is rich in protein, calcium, vitamin D, and omega-3 unsaturated fatty acid. I hope you gave it a try and feel healther and adverturous. Next, let's try what seems like a grain, quinoa.
Quinoa is a South American food that was originally grown in the Andes, where it has been a staple for the Inca people for over 6,000 years. When cooked, quinoa…

No matter how old you are, you should be concerned with your bones. Osteoporosis, which means "porous bones," is a medical condition affecting over 10 million Americans and is characterized by accelerated bone loss, leading to low bone mass and low bone density. Our bones increase in density from birth until about the age of 30. Beginning at age 30 we gradually lose bone density. We cannot…

The start of a new year marks the perfect opportunity to revisit familiar menu routines and jump-start healthy eating patterns. Adding a variety of fruits, vegetables, and whole grains to your plate will not only boost overall nutrition in your diet, but also broaden your culinary horizons. Instead of just trying to find new recipes for the same familiar ingredients, try expanding your…

Last week I recommended walking the streets of Portland to observe the lights and decorations for your holiday exercise. The question is, how far should you walk? And, have you been feeling lightheaded lately?
The University of Pittsburgh studied people enrolled in their Cardiovascular Health Study, a research project focused on risk factors for heart disease and stroke and based on…

The end of the year holidays are a time friends and family gather together to celebrate the end of the old year and the beginning of a new year. These special social gatherings and our social relations all year add immensely to our quality of life, and research has shown that they also tend to add years to our lives. Brigham Young University in Utah recently reviewed 148 studies involving more…

Sweet potatoes are a traditional fall food and a favorite for Thanksgiving dinner, but we should seriously consider them for a year-round, regular part of our diet, given their nutritional density, easy preparation, and low cost.
One cup of sweet potatoes has only 180 calories and is loaded with 7 grams of fiber. Increasing dietary fiber is a key step in a heart-healthy…

Thanksgiving Day is a time to be thankful for the many positive things in your life.
Research has found that maintaining this thankful attitude every day can improve an individual's psychological, emotional, and physical well-being. Adults with this sense of gratefulness have more energy, more optimism, more social connections, and more happiness than those who are not so grateful. They…

A big belly is dangerous to your health, even if you are not overweight. American Cancer Society scientists has completed a 14 year study of the association between waist circumference and mortality of men and women age 50 and older. The results found that after adjusting for body mass index (BMI) and other risk factors, very large waists-47 inches or larger in men and 42 inches or larger in…

Stomach and intestinal noises, such as rumbling, gurgling and growling, are a normal part of the digestion process, as food particles, liquids and pockets of gasses slowly move through your intestines. However, the loud stomach growling, called borborygmi, occurs when you haven't eaten and are hungry. Hunger and appetite are controlled by a complex system of hormone-like substances primarily…
Monday, Nov 8, 2010Yoga is not just for the young and ultralimber. Millions of Americans now practice yoga, and the habit is catching on with older adults who want to improve their strength, flexibility, and concentration. New research supports the benefits of yoga for older adults who may have weak leg or balance problems. This research found that even standing or chair yoga can greatly increase lower body…
