The sunshine supplement
Last week I learned that my vitamin D level is slightly below normal. My physician recommended that I take a daily vitamin D supplement of 1000 to 2000 IU.
I didn’t want the test, but what’s done is done. Now I need to decide what the test result means to me, and if I should follow my doctor’s recommendation.
A few years ago, vitamin D was the new wonder supplement. Various studies associated a low vitamin D level with an increased incidence of all kinds of diseases, including multiple sclerosis, rheumatoid arthritis, prostate cancer, breast cancer, … Continue reading
Two reports last week reminded Americans—again—that we are eating too much salt (sodium), and the media gleefully passed on the news—again—that what we eat is killing us.
Possibly. But it’s not helpful to focus the blame on salt, when it alone is not the problem.
The American Heart Association (AHA) reported that, on average, adults consume 4,000 mg of sodium every day, or about twice what’s recommended. The United States Dietary Association (USDA) recommends no more than 2,300 mg/day (about 1 teaspoon); the AHA advises less than 1,500 mg/day.
In a coordinated analysis, researchers from Harvard Medical School concluded… Continue reading
Out of sight, out of mind
The other day I was cleaning out a kitchen cupboard and unearthed an economy-sized bottle of calcium tablets. Oops! I should be taking one or two of those every day.
Or should I?
Everyone knows calcium is necessary for bone health. Most women have been told by their doctors that they need extra calcium after menopause because without estrogen’s help, bones do not absorb it well. Low calcium leads to osteoporosis, which leads to broken bones, which lead to huge health care costs. Oh no!
Too much of a good thing—or the wrong thing

Probiotics are of limited use
As a nurse, I often give patients the advice to eat yogurt when taking antibiotics to decrease the risk of developing diarrhea or, in women, vaginal yeast infections.
Why yogurt? Because it contains live, beneficial micro-organisms—now called probiotics—that are thought to replenish the “good” bacteria incidentally killed when taking antibiotics. In theory, eating yogurt makes sense. At best, it helps; at worse, you get a tasty snack with some extra calcium.
In the last few years, however, I have seen probiotic-laced products (fortified yogurt, snack bars, capsules) account for an increasingly large part of the … Continue reading
In another bit of good news this week, the Centers for Disease Control (CDC) reported that Americans are actually eating less fast food. Since 2006, an American adult’s total daily calories from fast food has dropped from 12.8% to 11.3%.
This number, although small, surprised me. It is no secret that America is in an obesity epidemic; more than one-third of adults meet the definition of obesity with a Body Mass Index (BMI) of 30 or higher. In children, the obesity rate is about 15%.
Obesity is tied to all sorts of chronic health problems such as heart disease, … Continue reading
