Home Remedy Of The Week: You Can Find It At The Deli Counter

No Comments »

A friend of mine had a bad reaction to a heart medicine, dropping her blood pressure to as low as 76/49 as a result. She was feeling understandably dizzy but didn’t want to go to the ER so she asked me if there was anything she could do at home to help raise her blood pressure. I recommended that she drink a large volume of water and take some salt tablets. She had no salt in pill form, and didn’t want to take it straight out of the shaker so asked if there was any other way to get the salt in. I asked her to describe the contents of her refrigerator and pantry, and made a mental note of what I thought had the highest salt content.

My friend thought that potato chips might do the trick, and was surprised when I told her that she had something almost ten times saltier at her disposal. Four ounces of prosciutto contained almost 2g of sodium, an entire day’s worth of salt! So she dutifully consumed the sliced meat, washing it down with about a liter of water. Two hours later she was back up to 98/66 and six hours later her blood pressure had returned to a healthy 116/83.

This was a rare case where a “high salt diet” had its benefits. In the case of ham versus hypotension, ham won… and saved my friend a costly, and unnecessary ER visit. Let’s hear it for deli meat!

Is It More Important To Make Patients Happy Or To Heal Them?

1 Comment »

One would think that happiness and healing are inextricably linked in healthcare, but the Happy Hospitalist (HH) raises an interesting question: is modern medicine’s emphasis on patient satisfaction (and shared decision-making) sacrificing our quality of care? A recent study found that patients who preferred their physicians to take the lead in their medical decision-making had shorter, less costly hospital stays.

HH argues that if physicians are expected to perform like airline pilots, reliably choosing/performing the best course of action for those depending on them, then patients should behave like passengers. In other words, passengers don’t tell the pilot how to fly the plane, nor should patients override a physician’s clinical judgment with personal preferences.

I think this analogy misses the mark because patients are rarely interested in making decisions about how a physician accomplishes her task, but rather which tasks she undertakes. Flight passengers aren’t interested in quibbling about the timing of landing gear, they are interested in the selection of their destination city. And so they should be.

While there may be a correlation between physician-led decision-making and shorter hospital stays, I’m not convinced that this translates to improved care quality. For the study subjects, discharge could have been delayed because the “empowered” patients insisted on ensuring that a home care plan was in place before they left the hospital. Or perhaps they wanted to get their prescriptions filled before going home (knowing that they couldn’t get to their home pharmacy over the weekend)? The study did not assess whether or not the discharge delays reduced readmission rates, nor did it seek to determine the cause of prolonged stays. This study alone is insufficient to draw any conclusions about the relative value of the patient empowerment movement on health outcomes.

While I certainly empathize with HH about the excessive focus on patient satisfaction surveys over true quality care, I strongly believe that an educated, participatory patient is our best ally in the practice of good medicine. There are simply too many cogs and wheels turning at once in the healthcare system to be able to ensure that the right care is provided at the right time, every time. We need all the help we can get to monitor our care plans in order to avoid medical errors, compliance problems and missed opportunities.

If you see something, say something. That principle applies to healthcare as much as it does to flight safety.

Eating Less Is More Important Than What You Eat

10 Comments »

I was raised by a health food zealot, and have been “eating clean” for most of my life. I have been an editor of a peer-reviewed nutrition and obesity journal, a food critic, and a dairy farmer. I am passionate about food – but I am also passionate about science. And I have to tell you, that for measurable health benefits, how much you eat is more important than what you eat.

I know this is controversial, and I’m certainly not saying that we should throw out all our leafy green veggies and grilled chicken and chow down on a diet of Twinkies and beer. But what I am saying is that the relative importance of food volume versus food quality has been misrepresented. We are focusing too much on specific nutrients and not enough on total caloric intake. I’d guess that what we eat is about 10% of the obesity problem, and how much we eat is 90% of the problem, but we spend 90% of our time talking about changing and improving what we eat rather than portion control strategies.

Consider these research-based findings :

1. The CDC has determined that 90% Americans get all the nutrients they need from the food they eat. Even “crappy” US diets actually do provide the minimum nutrients needed to avoid disease and malnutrition. I know this is surprising, but vitamins and supplements are simply not needed by most people.

2. Measurable health benefits occur from weight loss as small as 5-10% of total body weight. You don’t need to be a bikini model to achieve the health benefits of weight loss. You can decrease your blood pressure, sugar, and cholesterol with modest weight losses. In my opinion, leanness under about 25% body fat (for women) is mostly an aesthetic choice, not one of medical necessity.

3. Exercise benefits are largest at minimal levels. Going from sedentary to slightly active provides a larger health benefit than all additional increments of exercise. Thirty minutes of exercise, five times a week, is the minimum bar set by the Department of Health and Human Services. Anything beyond that is still valuable, but doesn’t decrease health risks by as much.

4. It matters more to lose weight, than it matters how you do it. Head-to-head studies of one diet versus another have repeatedly shown minimal differences in health benefits between the diet groups. The benefits occur from the weight loss, not from the manner in which it was lost.

This is all good news. Americans can achieve healthier outcomes with less effort than generally believed. Regular exercise, and a calorie-controlled diet (rather than rigidly controlling the macro and micro nutrients) are all that is required to substantially reduce the risk of many costly and unpleasant diseases. If you want to further optimize your health by eating a diet rich in fruits and veggies, whole grains, low-fat dairy, healthy fats, and lean protein please do so! But better to be a normal weight than obese due to eating too much of that healthy diet.

The bottom line is that you don’t have to give up eating the things you like, you just have to eat less of them. Even Olympian Carmelita Jeter eats Hostess cup cakes occasionally. And she’s the fastest woman in the world!

P.S. This blog post was inspired by a Twitter conversation with @Judith_Graham who said that the complicated issue of what to eat was too difficult to address in 140 character exchanges. Thank you, Judith!

P.P.S. Also, I’ve been thinking a lot about well-meaning but misguided (IMO) health policy issues raised by mayor Bloomberg’s ban on Big Gulps and the AMA’s endorsement of soda taxes. Bloomberg was pointing in the right direction (the size of the soda, not the soda itself was the problem), but I don’t believe you can regulate good behavior. Education and personal responsibility are the way to go.

50 Percent Of Physicians Disagree With AMA’s Soda Tax Endorsement

No Comments »

The American Medical Association (AMA) voted today to endorse taxation of sugary beverages as a means to raise money for anti-obesity programs. Interestingly, a recent physician survey at Medpage Today suggests that only 50% of physicians think that a soda tax is an effective public health strategy.

I am one of the 50% who feels that this policy will not be effective. In short, this is why:

1. You can become obese by eating and drinking almost anything in excess. Targeting sugary beverages is reductio ad absurdum. Did America become fat simply because of an excess supply of sugary fluids on grocery shelves? What about the super-sizing of our food portions, the change in workforce physical requirements, the advent of cars, escalators, healthy food “deserts” in poor neighborhoods, video games, and cutting gym class from schools?

Holding Coca Cola, et al. responsible  for our own over-consumption of  calories is both unfair and tantamount to spitting into the wind – something bad is going to come back at us. Consumers can easily get around the soda tax by buying sweet alternatives – which may have even more calories than soda. (Caramel latte anyone?) And then what? Are we really going to play public policy, food and beverage whack-a-mole?

Carmelita Jeter's Shopping Cart

2.  You can be thin and fit while eating and drinking almost anything. Obviously nutrition science has shown that a diet rich in fresh fruits and veggies, lean meats, low-fat dairy, whole grains, and healthy fats is the best for our health. However, please consider that the world’s fastest woman, Olympian Carmelita Jeter, eats Hostess cup cakes, Teddy Grahams, Welch’s grape juice, whole milk, and Gatorade. How do I know? Because she posted a photo of her shopping cart on Twitter (see image to the left). I obviously have no idea how much of this she eats – or when she eats it – but if the world’s fastest woman is powered (to some degree) by “Twinkies” then I think we should all think twice about demonizing certain foods/beverages in our anti-obesity fervor.

3. You can’t regulate good behavior. Human behaviors that may lead to obesity are simply too complex to regulate. Who would want to live in a world where government becomes the de facto “Nutrisystem” for its citizens, mailing out pre-packaged, ingredient-controlled meals to 312 million people per day, three times a day, seven days a week?  While that may save the post office from its imminent demise, we can neither afford to do that, nor do we need to.

People who believe that policy should drive behavior point to smoking bans that have cut down on smoking rates. While I agree that small improvements have been made in reducing smoking rates, roughly one in four people still smoke (depending on your source, this number could be as low as one-in-five), and one in every five deaths is still attributed to cigarette smoking. Hardly a resounding victory, alas.

But beyond the fact that policy changes (and the billions we’ve spent enacting and enforcing them) have resulted in a disappointing decrease in smoking rates, is the issue that cigarettes and food ingredients (such as sugar) are not analogous substances. While there is no safe minimum amount of cigarette smoke, our bodies need salt, glucose, and fat to survive. They cannot be cut out of our diet completely – nor should they. And the only way to force people to optimize their intake is to enact Draconian measures.

So instead of starting a food-fight, it’s important to accept the complexities associated with this particular health scourge and promote a broader, more-nuanced approach to wellness incentives. We have to attack this problem from the ground up, because a top-down approach requires our government to become an invasive, food and exercise nanny.

The good news is that one-third of Americans are not overweight or obese, despite our current “toxic” food/inactive lifestyle environment. Perhaps these thinner folks can be ambassadors for the rest of us, and reveal their secrets of healthy living despite our current limitations. Even with our best efforts, we need to understand that (like smokers) we will always have a segment of the population that is overweight or obese.

And as for the Olympians among us – they help to illustrate that obsessing over every morsel of food or cup of soda that we consume is not the way forward. Sorry AMA, I’m with Carmelita on this one.

Why Do Mosquitoes Bite You More Than Others?

No Comments »

Are you one of those people who’s been singled out for constant attack by mosquitoes? Ever felt like the designated bug decoy at a party? It does seem that those pesky biting insects have a preference for certain individuals, so the real question is: why you?

I wish there were a simple answer, but scientists have only isolated a few potential causes. It is likely that the full story remains to be elucidated – and may be related to small genetic variations in human odor. However, we do know that mosquitoes are attracted to carbon dioxide (that we expel as we breathe), and warmer skin temperatures. So I guess if you’re a heavy-breathing, hot-blooded person then you might need an extra layer of DEET? Or maybe hold your breath and wear a scuba suit when you’re in the presence of mosquitoes? Just kidding.

Interestingly, one small study notes that mosquitoes are more likely to land on people who are drinking beer. Since alcohol tends to cause vasodilation of blood vessels, the enhanced skin warmth could be a mosquito attractant. Others have postulated that tipsy people are slower at swatting off mosquitoes and are therefore more likely to be bitten.

My personal suspicion is that some of us react to mosquito proteins (injected when they bite us) more robustly than others. That means that while a mosquito’s bite may leave only a tiny, fleeting mark on one person, another might develop a large red hive that itches intensely. So if your immune system is hyper-reactive to mosquito proteins, you’re likely to suffer more from each bite that you receive. That alone could make you feel as if you’re being singled out by the nasty insects, when the reality is that others are being bitten just as frequently.

I guess the take home message here is that insect-repellent is still the best defense against mosquito bites, although some might argue that keeping a heavy-breathing, sweaty, beer-drinking guy nearby might provide an alternative decoy?

Enjoy your summer – and don’t scratch yourself to death!
