In the news

Osteoarthritis is common among seniors but even relatively small amounts of exercise can slow down its progress, even just one hour a week. In a group of more than 1500 persons who already had some lower extremity symptoms of arthritis, those who consistently did some brisk walking for at least one hour a week were eight times less likely to have a mobility disability in four years. That’s good news for people who really don’t like to exercise and might give them incentive to become even more active.

This study, reported in the May issue of the American Journal of Preventive Medicine, confirms several earlier studies. Ten minutes a day is a good start but the real benefits of regular, moderately intense exercise, lowering the risk of heart disease, stroke and type 2 diabetes, come with about one hour per day, done at least four days per week.

Folks who have a full-time job and a family might find that much exercise hard to schedule but it doesn’t have to be done all at once. And in the next issue of Carvings I’ll discuss stealth exercise.


 “Never do anything for the first time.”

That advice was given to me decades ago by my brother, a U.S. Marine and law enforcement officer. Of course, everything we do has had a “first time” but he was referring to scenarios that he would encounter in his military and civilian careers, for which he would continually practice in real time as well as in his mind. We have applied this principle in our CPR training program, not just the repetitive and physically demanding chest compressions and rescue breathing but especially in the deployment of the AED, which requires some degree of eye-hand coordination.

In his book, Blink, Malcolm Gladwell (you might remember him as the best-selling author of The Tipping Point) describes what happens in an emergency situation. He gives several examples of the severe impairment of our physiologic reactions – visual and auditory misperception, alterations in our perception of elapsed time, loss of fine muscle coordination, impaired recollection, to name a few. He describes the problems encountered by persons attempting to make a 9-1-1 call, such as not being able to remember those numbers, fumbling with the keypad, not pressing the green transmit button on the cell phone screen, panic while attempting to describe the situation to the dispatcher, etc.

As those of you who have been in our CPR class already know, even in our make-believe scenarios, students often fail to send someone to call 9-1-1 when they recognize unresponsiveness. (Remember our grammar lesson? “No response call 9-1-1!” – dropping the first period.) Some students immediately begin chest compressions without checking to see if the victim is breathing. In manipulating the AED, in almost every class at least one student tries to apply an electrode to the chest while it is still stuck to the yellow plastic separator. These are not intellectual deficits, they are common reactions to a first-time stressful situation. Think of how much worse things could get in a real emergency!

As Gladwell so clearly points out in his book, responders can learn to avoid those performance deficiencies by training and practice – and practice, and practice.

We strongly recommend to our CPR students that they review emergency scenarios regularly – specifically, that they do so on a weekly basis, and that they get recertified every two years.  Several our our graduates have told me that they responded automatically to a collapse or other emergency as a result of their training, because it wasn’t “the first time.”

Thanks to brother Tom and Malcolm Gladwell.

A childhood vaccine that grownups should have.

          Measles has been in the news recently because of several large outbreaks, due primarily to the failure of parents to allow their children to be vaccinated. But there is another “childhood disease,” whooping cough, that has also become more common for the same reason.

Whooping cough, whose medical term is pertussis, is life-threatening to infants below the age of six months. It has an agonizing, sometimes fatal course. It is almost entirely preventable if the mother has received the pertussis vaccine in the prior couple of years, including during pregnancy. The antibodies that she passes to her child before birth provide protection during the six months that it takes for three injections of the DPT (Diphtheria-Pertussis-Tetanus) vaccine to reach protective levels in the infant.

Whooping cough is so named because of the unusual sound that a struggling infant makes in trying to take in a breath during severe coughing spells. In older children and adults there is no whoop; the illness takes the form of bronchitis – usually about three or four weeks of cold symptoms with moderate coughing and discomfort. If an unimmunized or incompletely immunized baby is exposed to an adult with pertussis, that infant can become seriously ill.

A strategy that works

Before the infant arrives, persons over the age of eleven in the household and any prospective visitor (especially grandparents!) should receive a DTaP booster. (The “a” designates a new version of the DPT vaccine.) Protection against pertussis lasts for at least five years; protection against diphtheria and tetanus lasts much longer, perhaps a lifetime, making it an even better deal.



Trans fats are gone. Do you miss them?     

Trans fats are chemically engineered vegetable oils such as peanut and cottonseed oil that prolong the shelf life of baked goods. Because they are uncontestably related to heart disease and stroke the U.S. government banned them, effective June 2018.

Food manufacturers growled and complained but many of them saw the writing on the wall and began to eliminate them in 2015 when the FDA announced the 2018 ban. Some companies removed trans fats from their products as early as 2006.

Denmark implemented a ban in 2004 and since then has seen a dramatic decline in the incidence of cardiovascular disease. On a smaller scale, people who lived in those parts of New York State where trans fats had been banned for three or more years were found to have significantly lower rates of heart attacks and stroke.

One less thing to worry about but some people fear that a ban on sugar will be next. Don’t bet on that one making it through Congress!

Here we go again: eggs, cholesterol and heart disease!

Is your brain being scrambled by the eggs are healthy/eggs are not healthy studies that the media revel in? It’s like watching a tennis match as the ball goes back and forth.

The latest study reports that “higher consumption of dietary cholesterol or eggs was significantly associated with higher risk of cardiovascular disease and all-cause mortality in a dose-response manner”. The subjects of the study “self-reported” their egg intake to the researchers.

A prospective study that included more than 28,000 persons in China reported that eating seven or more eggs per week was not associated with an increase in cardiovascular disease or all-cause mortality. In fact, the egg-eaters in that group had a nearly ten percent reduction in stroke.

Hmmmm! Neither study looked at “egg helpers” – my term for bacon, sausage, ham, butter and hash browns – which may be why eggs appear to raise cholesterol and heart disease. Several publications have revealed that as your dietary intake of cholesterol goes up your liver produces less cholesterol, a feedback mechanism that has been recognized for decades. It is also well established that saturated fat, which makes up a large percentage of those egg helpers, raises cholesterol levels, especially the harmful type.

Is it possible that the Chinese egg-eaters are more likely to have veggies with their eggs while Americans are more likely to combine them with bacon or sausage?

Eggs have healthy protein (about 5 or 6 grams per egg) as well as several vitamins and minerals. And no carbs! A veggie omelet made with frozen mixed vegetables is one of the healthiest breakfasts you can have.

Another tip: add a tablespoon of extra virgin olive oil as you’re scrambling the eggs. You’ll be getting some healthy monounsaturated fat and the pan will be easier to clean.


Keep that important stuff on ICE

       If you go to the emergency room they’ll want to know if you have any significant illnesses and will ask you what medications you are taking and the dosage of each.  What if you don’t know, can’t remember or are unable to communicate?

       ICEIn Case of Emergency is a list of your medical conditions and prescription medications that you can present to emergency medical responders. It can be a simple list carried in your wallet, a more formal ICE Medical Standard ID Card or a smartphone app that costs only 99 cents. The red ICE icon is easy to see on your cell phone for emergency personnel to access. Google ICE medical standard for details and materials.

Another program, the Vial of Life, provides a decal that can be stuck on a baggie to be placed on your refrigerator door and a decal for your front door. Into the baggie you can insert a form listing your current medical information and you could include a copy of your EKG, a Living Will and a recent photo of yourself. You can also store your information online at their free web site.  Google Vial of Life for details.

            Note: the information provided by both of these systems can be made available if you are away from home. ICE appears as an icon on your phone. Your Vial of Life information is online but it requires a username and password.

The ketogenic diet — again.

The ketogenic diet originated in the early 1920s when it was found that children with seizure disorders (also called epilepsy) improved considerably when their diet consisted mostly of fats and almost no carbohydrates. The kids also drove their parents nuts because of their intense craving for carbohydrates.

The Atkins low-carbohydrate diet is not as severe and it often works to help you to lose weight. Any diet that sharply limits refined grains and sugar is likely to result in weight loss. The downside is that Atkins dieters have a hard time limiting their carbs so drastically that they manage to go into ketosis – deriving most of their energy from fat in their diet and their own body fat. In addition to offensive breath odor, those who do adhere to the diet are often constipated and irritable – the latter effect making their family members unhappy.

The present-day ketogenic diet consists of only 2-5 percent carbohydrates and 70-90 percent fats. The rest is protein. It should not be confused with the Paleo Diet, which eliminates all cereal grains and dairy products but includes plenty of fruits and vegetables. The Paleo Diet provides plenty of plant-based vitamins and antioxidants but the ketogenic diet does not. A poorly-designed ketogenic diet can lead to complications such as fatigue, kidney stones and gout. A rare event in children who have been placed on the diet for seizures is cardiac arrest.

How about a compromise: the Mediterranean Diet that we described in the last blog. It has plenty of fat in the form of healthy olive oil but almost no saturated fat. More than half of its calories come from fruits and vegetables; dairy is in the form of cheese but only a little, mostly as a garnish; protein comes from fish and poultry – and an occasional meatball or two with a little pasta. This diet is documented to be heart-healthy, especially if you include a glass of red wine every day! No bad breath, no constipation and everybody is happy!


      It’s not a problem for most people but the subject comes up from time to time among my audiences and it’s one that I dealt with regularly during 35 years of pediatric practice: ear wax.

Some people have almost no ear wax; some persons have an abundance of it and it can be a problem. A physician whose view of the eardrum is obscured by wax can’t be sure if a child has an ear infection. We learn early in our training how to scoop it out but it’s not always easy. When it completely fills the ear canal it may impair hearing.

Your genes determine how much wax you form and what kind. It can be sticky and gooey or hard and crumbly, the latter being typical among Asians.

What NOT to do: never use Q-tips, bobby pins or anything else to blindly sweep the stuff out. I have seen punctured eardrums and dislocated ossicles (the tiny bones of the middle ear that are necessary to transmit sound) in persons who thought that a cotton swab can do no harm.

Over-the-counter drops to dissolve ear wax are a waste of money. There is a simple, inexpensive solution that I have never seen to fail: hydrogen peroxide. Simply place two drops in each ear canal once a day after showering or at bedtime. Let it drain out. About one week of daily treatment will break up the wax that will fall out while you sleep. I have had a couple of patients whose wax build-up was so long-standing that it took a full three weeks of daily hydrogen peroxide drops to eliminate all of it.

I hate to take business away from my physician colleagues but it’s not necessary to make regular trips to the doctor to flush it out. Your ears don’t need an enema – a few pennies worth of hydrogen peroxide (make sure it’s fresh) will do the job while you sleep.


Upcoming presentations

Monday, March 4, 1:00 p.m., National City Library, What have we done to food? The discussion includes GMO foods, irradiated foods and numerous other topics.

I have been invited to be a guest speaker at the 2019 Ancestral Health Symposium to be held at USCD, August 8-10. The topic will be Being a kid in the Stone Age, which gives interesting insights not just into what life was like 50,000 years ago but what we can learn from way back then that will help us and our children become healthier.

I’ll send more information when the program has been finalized.

Evolved to exercise

That is the title of an article in the January, 2019 Scientific American. To quote from the article: “Unlike our ape cousins, we have evolved a dependency on physical activity. We must move to survive.”

So how much do we have to “move”? A particular group of hunter-gatherers studied by researchers from the University of Arizona found that they logged more physical activity in a day than the average American does in a week – about 12,000 to 18,000 steps a day – and they have virtually zero coronary artery disease, high blood pressure or type 2 diabetes. And it’s not because they don’t live long enough; about 20 percent of hunter-gatherers live beyond the age of sixty.

It’s not practical for most of us to wear a pedometer that would help to know when we’ve reached a target of 10,000 steps a day, which many experts recommend. After all, what would you do if you were getting ready for bed and you realized that you had only taken 7,000 steps that day? Most of us would stop wearing the pedometer!

This is easier: spend at least 2 ½ hours a week doing moderately intense exercise – that means working up a sweat. Better yet – one hour a day at least four days a week. Studies show that 2 ½ to 4 hours a week will help you to maintain weight and to significantly lower the risk of type 2 diabetes. According to the Scientific American article it will also cause you to grow new brain cells, improve your memory and postpone the onset of age-related cognitive decline.



The final step (at least for now) to prevent dementia and Alzheimer’s disease: follow the Mediterranean diet.

       Nope – it’s not what you’ll find at your local pizza parlor. The true Mediterranean diet consists mostly (about 50 percent) of vegetables, including potatoes. (Not French fries!!) Not a lot of meat either and it’s mostly chicken and fish. Pasta, of course, but only about 3 ½ ounces at a meal.

A high adherence to a Mediterranean diet is associated with a low risk of Alzheimer’s disease. There are several reasons.

No refined grains (white flour) but mostly whole-grain baked goods. Almost no sugar either.

The high intake of plant foods means lots of antioxidants, which lower inflammation, a major driver of heart disease, stroke, cancer, type 2 diabetes and osteoporosis.

A higher intake of fish with its protective omega-3 fats.

Lots of healthy fat in the form of olive oil.

And of course, a glass of red wine every day!

Flu season isn’t over yet!

We’re still a couple of months away from the end of the flu season, but the virus doesn’t play by the rules! Although the official end of the season is in May, infections and deaths from influenza occur year-round. We may not have reached the peak of the season yet.

There is no substitute for the flu vaccine and it’s not too late to get yours if you have not yet done so.

At least four children have died from influenza so far. The best reason for YOUR flu shot may be to protect a child, grandchild or a visitor’s child.



Another step to prevent dementia and Alzheimer’s disease: go back to school

       Not only is it never too late to learn something new, but putting your brain back to work could give you several more years of clear thinking and a better memory.

Become bilingual: research over the past decade shows that those who speak a second language can delay the onset of Alzheimer’s disease by about SIX years. Those who know three languages can extend it even longer.

The good news – it doesn’t matter when you start!

If you are musically inclined – but especially if you’re not – taking up a new instrument also delays the dreaded dementia. And make it a different instrument. If you played the piano as a kid, learn the guitar; if you played a wind instrument back then, learn a keyboard instrument now.

Puzzles, games, a new craft hobby or a new genre of books all contribute to the establishment of new brain connections. But it’s important to engage in these activities on a regular, i.e., several times a week, basis.

Lessons from the Masai

The Masai (also Maasai) of Africa have been popularized as existing only on the meat, blood and milk of cattle while avoiding plant foods. That observation by early anthropologists was incorrect. It is true that their cholesterol levels were surprisingly low for meat-eaters and they appeared to avoid heart disease. These unique tribespeople are not hunter-gatherers but pastoralists whose cattle have low levels of fat, and they eat more plant foods than was recognized.

Their daily intake includes soups or teas made with dozens of herbs and “snacks” derived from plant resins and gums. These plant-based materials contain substances that not only keep blood cholesterol levels low but have numerous compounds that have anticancer, antimicrobial, anti-diarrheal and clot-inhibiting properties. Some even kill the parasitic worms that are ubiquitous in Central Africa! Add to that their characteristic leanness and their high level of physical activity, it’s no wonder that they don’t die from heart attacks.

The lesson for us? Eating meat or drinking blood (!) and milk are less likely to cause heart disease as long as you have lots of plant foods in your diet and stay thin.



Another step to prevent dementia and Alzheimer’s disease: think better thin

       “Overweight in middle age is associated with dementia in old age.” Not an original statement by me but it’s from a medical journal article, one of many that show that obesity contributes to Alzheimer’s disease and dementia. Persons who are overweight have 4 percent less brain tissue and 8 years of premature brain aging; obese persons have 8 percent less brain tissue and 16 years of premature brain aging.

Considering that 40 percent of Americans are obese and that the projection for 2050 is 50 percent – probably an underestimate – what kind of befuddled society will the next couple of generations be living in?

The take-home message: do whatever you can to keep your weight at a level that is normal for your height and frame. To find out what that is, just Google what is normal weight for my height.
