it's a start, but barely that

Tuesday, May 25th, 2010

I recently read an Associated Press article headlined "Food companies say they'll remove 1.5 trillion calories" and was initially impressed until I got into the reality behind this tiny start toward reducing childhood obesity. It turns out that the highly vaunted amount works out to 12.5 calories per person per day. I've blogged and written elsewhere that 50 calories a day works out to be five pounds a year (3,500 calories equates to a pound), so this initial effort from the Healthy Weight Commitment Foundation equates to a pound and a quarter a year.

That may be a start, but it sure isn't much of one.

If we cut our daily intake by fifty calories (and that shouldn't be hard considering how much Americans and some others eat), we'd lose five pounds a year. One hundred calories less a day + 100 calories worth of exercise would result in a loss of twenty pounds over a year. I've done a little better than that over the past year and I'm down about twenty-five pounds.

But let's go back to the food companies, the Healthy Weight Commitment Foundation has over 80 companies, including many of the big names. Sure they're responding to Michelle Obama's speech given in March to an industry meeting, and making some efforts (I'd call it a tiny one) to cut sugar and fat from their products (and hopefully salt also). But the huge number in the headline, 1.5 trillion calories, has to be put into perspective. Twelve and a half calories a day per person sure isn't much.

I think we all need to eat more fruits and vegetables, lose our mid-section excess and then keep it off by increasing our exercise or some combination of diet and exercise. I think the food companies need to cut their products calorie load a lot more than a mere 1.5 trillion calories. Until they do, and maybe even after they do, we should, as much as possible look for ways to eat healthier.

That's easier to say than do for many people. Fresh fruits and vegetables aren't cheap and families living on tight budgets may struggle to put healthier meals on the table. So my push would be for our government (and the food companies) to subsidize food, especially for kids, that's built around eating more fresh fruits and veggies and less processed foods.  We also need to get our kids outside, away from the computers, cell phones and other sedentary lifestyle items and get them interested in walking, running and biking.

It's time and past time for all of us to help bring about the diet and exercise changes we need, both for ourselves and especially for our kids and grandkids.

Then that amazing headline with its dazzling 1.5 trillion calorie figure could actually be put into perspective. Folks, it's just a drop in the bucket. We need to fill that bucket.

Getting help in remembering to exercise

Tuesday, May 18th, 2010

I read an interesting article this morning. A study conducted by researchers at Stanford using subjects averaging in their mid 50s and previously inactive showed the importance of social support in helping people develop and maintain an exercise regime. The project followed adults, with an average age in their mid 50s, for a year and showed that people who got phone calls, even monthly ones,  from a health educator markedly increased their time spent exercising. That's compared to a group who only got initial health education classes. Even automated phone calls work, but a human touch was best. Those new and improved health habits held at the 18-month followup.

There were other bits of information I gl.eaned: the majority of people, like me, prefer to exercise alone. My wife participates in four exercise classes a week; I don't join her in any of those. I often think my way through issues as I exercise (especially during the 65 minutes I spend almost every dayon a recumbent bike), zoning out and working through issues or just allowing thoughts to come up as they will.

The Stanford lead investigator, Dr. Abby King is a PhD professor of Epidemiology and Medicine at Stanford's Prevention School of Medicine Research whose major research study relates to the role of physical activity as it links to other healthy behaviors and promotes improvements in life-coping mechanisms. She herself usually is a loner when it comes to exercise, but sometimes drips out for a period of weeks and then tends to join a small class to get back into her usual pattern.

What I take from this is if you don't find it easy to get into a pattern of regular exercise, find a buddy who will call you from time to time. Most of us will never end up in a formal research project like Dr. King's; almost all of us could help a friend and be helped in return.

Lynnette was just on the phone calling her another woman who is in the twice-weekly "Strong Women, Strong Bones" class she takes. She's developed a brand new, close friendship through this class, frequently has a cup of coffee afterward with her exercise buddy and the two of us, from time to time, go to dinner with her friend and that woman's husband.

As we age, I think social support is crucial and, if friends can help us stay in shape, maybe lose a few pounds or keep those off we've lost already, they have even more value in our lives.

So find an exercise buddy or even someone who'll help you keep working out, whether you walk together, go to a gym together or just make phone calls to support each other's good habits.


Another good book

Friday, May 14th, 2010

I recently ordered a book by Susan Yager with the intriguing title The Hundred year Diet: America's Voracious Appetite For Losing Weight. I'm waiting for the book to come in, but the quote in The Wall Street Journal's book review section was enough to hook me. It mentioned a prior WSJ article with a great line from a physician saying, "If there were a drug with the same benefits as exercise, it would instantly be the standard of care."

Yager's book traces our preoccupation with dieting from the early 19th century to the present. Now we're tracking our calories, watching out for high-fructose corn syrup, but prior fads had us on high protein diets, chewing our food and chewing it and chewing it before we finally swallowed the mouthful, avoiding this food or that.

I'm waiting for Yager's relatively slim volume (it's only 260 pages in length), but in a few minutes I'm going to go to the gym and ride a recumbent bike for 65 minutes (or more) until I'm past the 20 miles/650 calorie mark. I'll do some stretches and work on a few machines, but for sure I'm going to ride the bike.

Lynnette in the meantime will be out walking. A recent book by Miriam Nelson and Jennifer Ackerman with the title of "The Strong Woman's Guide to Total Health" suggests brisk walking for an  hour a day. Nelson was the co-chair of the group that authored the 2008 Physical Activity Guidelines for Americans and directs a center at Tufts which concentrates on obesity prevention.

So there's two approaches to losing weight. I don't believe in "fad diets." I do believe in eating less and doing more. Our diet increasingly focuses on more fruits and vegetables and we're looking in to the options with a local CSA (community-sponsored agriculture) organization. We can purchase an "egg share," a vegetable share," a winter vegetable share," and/or a "fruit share."

Here are the concepts that appeal to me strongly: buy local, eat more of the good stuff and find some form of exercise that you're capable of and will do on a regular basis. Carve some time for it out of your busy life. Eat slower. Enjoy your dining companions conversation. Drink some water before that first bite. Serve really small portions of anything you crave that is obviously fattening.

Stay away from fad diets.

How much do I need to exercise?

Friday, April 30th, 2010

I keep running across short articles on exercise and its resultant health improvements; they vary a lot! One, taken from USA Today and published in the Journal of the American medical Society, reported on a long-term study done by researchers at Boston's Brigham and Women's Hospital and Harvard Medical School. This was a huge project, following 34,000 women for thirteen years. The group's average age was 54 when the project began and the women were eating a regular diet and not trying to lose weight. Over the extended period of the study the average weight gain was six pounds. Not very surprisingly, those who exercised more gained less than those who were relatively inactive. But notice they weren't dieting, just exercising.

A second article included multiple takes on excercise. A cardiologist from the Mayo Clinic in Rochester mentioned an overweight patient who started to consume a better diet and got moderate exercise. He lost weight and clearly improved his lipid panel results (the surprise ending to that story was he was his own patient in this instance).

Comments made at the yearly meeting of the American College of Cardiology supported the moderate exercise concept, with a number of studies showing more aggressive approach to preventing heart disease were no more effective than moderate ones. Other studies showed that adding multiple drugs to lower lipids didn't seem to offer additional benefit and a large NIH study concluded that aggressively lowering systolic blood pressure (that's the upper number your doc looks at when you have, for example a blood pressure of 145 over 95) wasn't more effective in preventing strokes or heart attacks in a group of over 4,700 diabetic patients.

What does this all translate into for you. At least my approach is to eat well, keep my weight down and get some exercise as often as possible, sometimes by going to the gym and sometimes by walking up and down the stairs to my second-floor office. I've stayed away from using lots of meds for minimal changes in my lipids and don't have a blood panel done very often (The last time I had one, all my results were okay). Of course I've worked hard at losing the roll around my middle (I've gone from a 37-38 inch waist to 33-34 inches in the past year) and cut my weight 25+ pounds. The dose of my blood pressure medicine was cut in half when I did so.

Listen to what your own doc tells you, but I strongly suggest you take some steps yourself to improve your health. They don't always have to be huge ones, but, in the final essence, you're the person who can do the most to extend your lifespan. Start by doing some walking; think about small things you can do arround the house that burn calories (like my extra stair climbing), ask your doc if you're okay to do more strenuous exercise and if you do so, very gradually increases in your workout pattern make sense to me).

But whatever you do, don't just sit there and let the pounds accumulate, especially pounds around your waist.

Working in the Low-Salt Mines

Wednesday, April 21st, 2010

We're finally catching up with reality, at least in one arena. In the past week I've read two local newspaper articles, one article in the Annals of Internal Medicine and an accompanying editorial in the same monthly journal from the American College of Physicians, all on our need to decrease our salt intake.

Those of us who've spent much of our medical careers dealing with the treatment and the consequences of high blood pressure, medically termed  hypertension, have been on a low-salt kick for years. Both of my parents and, eventually my older brother had hypertension, so I watched my blood pressure for years and, when it went up to high normal, cut way back on my salt intake. I also started to lose weight and to exercise more.

So two days ago I read an article titled "Shaking the Salt Habit." That was written for our Fort Collins paper and was followed by one today, from the Associated Press, titled "Too Much Salt: Report urges FDA to force rollback. Then there were the two medical pieces which came out in the April 20th edition of the  Annals. The editorial encapsulated the concept: "We Can reduce Dietary Sodium, Save Money, and Save Lives.

The bottom line is the American diet contains roughly twice as much salt as is optimal for health, nearly 4,000 milligrams vs. the maximum recommended of 2,300 mg. for young, healthy adults, and the 1,400 to 1,500 mg. that is the suggested maximum for people with high blood pressure, for African-Americans and for anyone older than 40. Much of the excess comes from processed foods.

Other countries have already made progress along the lines of cutting average salt intake (salt, of course, is sodium chloride, but I'm used to using either term). The UK started in 2003, and cut salt intake by an average of 9.5% The Annals article suggests if we were able to do the same, gradually perhaps so people didn't think the taste of food was inferior and started salting things at the table, we'd save lots of lives.

The consequences of hypertension include heart attacks, strokes and kidney failure. That less than ten percent decrease in our dietary salt could prevent over a half million strokes and just under a half million heart attacks in our 40 to 80-year old group. That would save over $32 billion dollars in medical costs.

The UK plans further cuts in salt intake, up to a 40% decrease by 2012. Japan, Finland, Ireland, Australia and Canada plus other countries are also implementing similar programs.

We don't cook with salt for ourselves, decrease the amounts specified in recipes when we cook for others, don't add salt at the table and tend to avoid processed foods. I wondered if we were getting enough iodine, added to most or all salt you purchase, but the salt that goes into processed foods, according to the articles I read, doesn't have idoine anyways. Plus our senior vitamins have the RDA (recommended daily allowance) for iodine anyway. So I quit worrying that we'd develop thyroid problems.

The bottom line is we Americans need to wean ourselves off our excess salt habit and doing so will both improve health and save a healthy chunk of change.

Pushing the edge: a hodgepodge

Friday, April 16th, 2010

I wrote recently about Springfield's horseshoe sandwiches using them as one example of things in our society's food frenzy that I don't want to join in. Since then I've run into a number of other examples and, fortunately, some opposition to these. I'm going to quickly describe a few of the trends I view as potentially dangerous for those of us who want to stay slim (or become slender) and remain healthy.

One article described how high-end restaurants are experiencing a boom, in some case having up to 30% more business. I read that with perhaps a touch of envy, but decided that the trend for fancy dining came from abundant crops and cheaper prices for strawberries, wild mushrooms,and some varieties of carrots.  Those things I can buy for myself in the farmer's market or the supermarket

My greater concern came from reading two articles on foods being offered for sale that offer much greater risks than fancy restaurant meals. One was on bushmeats, illegally-imported flesh that comes from bats, monkeys and rodents...considered by some to be delicacies and apparently smuggled into the NYC area. Now you may not live near the New York City so this may appear to be of distant interest, but those strange meats have been found to contain a strain of a virus that is distantly related to HIV and many scientists think that consuming such products is how humans first came to be infected with HIV.

Then there's the unpasteurized milk debate. Public health officials (my Dad was one of those), are absolutely against drinking "raw milk," though its advocates claim it has many health benefits lost when the milk is pasteurized, defined as being heated enough to kill harmful bacteria.  In March the FDA reported twelve cases of sickness in the Midwest that apparently were tied to a dairy selling "raw milk." The agency is reviewing its policy on hard cheeses made from raw milk. At present you can purchase those if they are aged sixty days or more. Fresh cheeses made from raw milk have also been linked to disease out breaks.

So you make your choices and decide for yourself. There's a range of food available from the exotic to the expensive to the somewhat mundane. Just remember, to start with, that prior to 1938, when pasteurization became the norm, cow's milk was responsible for a quarter of all water- and food-borne illness. And bushmeat may have led to our current HIV epidemic. As for fancy restaurants, I'll save them for special occasions.

There's fat and then there's fat

Tuesday, April 13th, 2010

For the past few years I've heard passing references to brown fat and white fat, but never understood the difference between them. Today I read The Wall Street Journal's "Personal Journal" section and saw an article that finally clarified the two kinds of fat for me. It also led me to believe there may be developments coming in the field that could potentially (lots of qualifiers there) help our obese and overweight population.

So let's go back to the kinds of fat. Brown fat is different from the kind we tend to accumulate arround our mid-sections as adults if we eat too much and/or exercise too little. It's actually brown in color, found in babies, and contains lots of the heat-producing little cellular "engines" called mitochondria. Little kids are more at risk for hypothermia than adults, so they have more brown fat as a protective mechanism.

Can we use this natural calorie-burning mechanism when we're overweight? In a variety of places researchers are attempting to solve this question. One mechanism for revving up brown fat, at least in mice, appears to be exposure to cold. Some studies have shown that humans may adapt to cooler temperatures by increasing the amount or activity of brown fat, but we're a long ways from anything definitive.

The question isn't as simple as it may seem. Lean men seem to respond better than obese men to exposure to cold, at least in terms of brown fat activation. A map of the United States in another article showed obesity, in general terms, to be more prevalent in the Southeast, but many factors may contribute to that finding.

Harvard and MIT teams are attempting to find a way to produce more brown fat by activating a protein called PRDM16. Their initial work is near completion, but development of an actual marketable drug that works in this fashion is at least five to ten years away.

So in the meantime, should we all turn our thermostats down to say 65 degrees. I think that's a good idea; it would save fuel, decrease our emissions perhaps (thereby helping prevent global warming), and maybe, just maybe help us to lose a few pounds.

Subtle messages

Wednesday, April 7th, 2010

I was leafing through The Wall Street Journal this morning, quickly, as I got up late, will read a book for my men's book club most of the morning and then go to Loveland, eight miles south, to lunch at a restaurant I've never eaten at before. I'm going there to meet a writer friend whose book I've been proofreading.  I saw the headlines in the front section of the paper and will return to them later, but was struck by an article in the last section, the one called "Personal Journal."

The article's title was "What Your TV is Telling You to Do." That caught my attention so I read the whole thing. It's about NBC's use of the technique of "behavior placement." Instead of trying to sell you a specific product by having the star of a show drink, eat or use it, this idea is to show you a kind of behavior you may then decide, consciously or unconsciously, to emulate.

The thing that's different here is that some NBC's shows are now sending you messages, or rather signals, to recycle, exercise and eat right. Presumably they're not just doing this because it's the right thing, but, in part in least, because it will help them sell ads. TV has enormous power to get huge numbers of viewers to do something, because their favorite character does it.

In this case the stars of various shows will be exercising or eating healthy food choices. I'm going to wait and see what the outcome is and maintain a goodly amount of skepticism, but the overall concept is one I love.

For years we've been sold, via ads (which I mute and many who use Tivo skip), products that by no stretch of the imagination could be termed healthy choices. Now, finally, someone is going to try to influence us to make better choices. I'm all for it.

Things I don't want to eat

Monday, April 5th, 2010

I found an article in The Wall Street Journal recently that raised my hackles.  On March 30th, 2010 the paper talked about a food fad in Springfield, IL, quoting the owner of a local eatery there as saying, "We've made something very unhealthy even unhealthier."

Apparently the city has an area favorite, the horseshoe sandwich, which is incredible enough in its original form (large plate sized, open-face with bread, meat, lots of fries absolutely doused with melted cheese, versions ranging from pony shoes at 1,300 calories to regular horseshoes at 1,900 calories each). That many calories is the equivalent of gulping down nine jelly doughnuts according to the article. One place in Springfield briefly tried a relatively healthy version, but found it unpopular.

Now the featured restaurant came up with a  extra-grease-added format with the fries and meat inserted into a tortilla, then deep fried and finally given a river of cheese sauce. It's a 2,700 calorie horseshoe sandwich said to be equivalent to five Big Macs.

This local tradition, that is the horseshoe sandwich itself, has been around since 1928, flourished since the 1970s  and in 2009 the Springfield convention center hosted the initial World Horseshoe Cook-off.

All of which wants me to stay away from Springfield and its restaurants. I had cousins there many years ago, but, even as a once-a-year birthday "treat," the horseshoe is not for me.

For years I've been amazed at some of the food monstrosities our American fast-food places serve. I understand they're trying to get with the trend toward healthier eating and maybe they're succeeding, but here's one town where the opposite has happened. One state worker is quoted as saying, before her monthly indulgence, that she eats salad all week.

None of us is perfect in following a diet; I ate more yesterday at my relatives' home for the holiday dinner than I normally would and even ate some things (chocolate-covered apricots) that I'd never purchase for myself. But falling off the diet wagon..briefly (I'm still within my three-pound-over-target-weight limit), is one thing; eating these culinary death traps regularly is quite another. I just talked to my CPA about picking up our tax forms and, in doing so, mentioned the horseshoe. He called it "a heart attack on a plate."

So that's Springfield and its own tradition; the problem I have is what can I find to eat when I eat out elsewhere? I look carefully at menus, choose Subway if I have to eat at a fast-food restaurant on the road and usually stick to my favorite Thai place for meetings and treats. I think that our love affair with restaurant food has been a major health hazard for many of us. It's time for a change.

Even The Economist

Wednesday, March 31st, 2010

I get lots of blog ideas from The Wall Street Journal, usually from their last section, oriented to the personal and rather eclectic in content. Four days ago I was reading my copy of The Economist and was somewhat surprised to see an article in their Business section that called out for a blog post. The title of the piece was "Pepsi gets a makeover: Taking the challenge."

The focus of the article was on Pepsi's CEO wanting the firm to make products with less sugar, salt and fat. She even plans to remove all of the company's drinks that contain sugar from schools by 2012.

Bravo, I said and read on. It seems that she's gotten the message. She wants to help keep food companies (or at least hers) from the fate of their tobacco-company distant relatives, noting the latter firms have been impugned for the deleterious  health-related outcomes caused by their products.

I was unaware that Pepsi owned Quaker, but found fascinating the plans to alter their marketing of those products also. The Pepsi boss seems quite serious in her efforts, and although they clearly must be driven, in large part, by an attempt to capture/maintain market share, I applaud the concept.

I personally drink few soft drinks (One Caffeine-free Diet Coke a day), but I hope this effort by a major food company will be followed by all the others. it's about time!
