| Off the cuff | |
| I've talked a lot about the dangers of overdiagnosis in these updates. Usually, with respect to cancer screening, and the serious risks of unnecessary treatment. But that's not the only area where debates over screening protocol are taking place. A group of researchers recently followed more than 400 patients for five years. And they found that the current convention of taking blood pressure readings at every doctor's visit--which for many is several times a year--might be bad medicine. Blood pressure is a notoriously fickle number that can easily rise due to temporary anxiety or improper reading technique. And as it turns out, screening at every visit results in significantly more false positive hypertension diagnoses than simple annual readings would. It also makes it more difficult to diagnose cases that truly require treatment. I have to say, I'm glad we're talking about this. The fact is, accurate diagnosis of high blood pressure is just as important as accurate cancer diagnosis. Because at the end of the day, the stakes can be just as high. But the risks of overdiagnosis are very real, too. They may not include radical surgery or chemotherapy. But they often do involve prescriptions for blood pressure medications that you just don't need. Medications like beta blockers, calcium channel blockers, and diuretics. All of which, at one time or another, have been linked to issues like breathing trouble, weight gain, mineral depletion, and even increased cancer risk. If putting away the blood pressure cuff can help to put an end to this massive overmedication, I'm all for it. Especially since the best remedies for hypertension--regular exercise and my New Hamptons Health Miracle--don't require a prescription pad to become a part of your life today.

| Risk management | |
| Dear Reader, Remember when I said a couple of weeks ago that the debate over calcium was far from over? Well, just as I predicted, the saga continues. It's time to set the record straight on calcium supplementation, once again. There are so many conflicting stories out there that I think it's important to tackle this issue one more time, for safety's sake. First, though, a little background: Calcium is a vitally important mineral and it's one of the most abundant in your body. It's also tightly regulated. Low levels are a problem for a lot of reasons--most notably, higher risk of fractures and bone loss. This is why so many people--especially women--take a calcium supplement. But in recent years, the wisdom of this decision has been called into question. Several studies have shown that calcium supplementation could lead to a higher risk of ischemic heart disease and stroke--while other published research has refuted those claims. So what's a girl to do? The study I want to tell you about today involved nearly 61,500 Swedish women. Researchers wanted to find out whether long-term calcium intake--through both diet and supplements--has any links to all-cause or heart-related mortality. The women were divided into categories according to average total calcium intakes. The lowest intake came in at 572 mg per day, while the highest was 2,137 mg per day. Researchers followed up on the women for an average of 19 years. As it turns out, there's a window of safe calcium intake. And being on the wrong side of it--in either direction--could be deadly. Women with dietary calcium intakes higher than 1,400 mg per day were at the highest risk of all-cause mortality and death from heart disease. (But not from stroke.) And mortality rates also increased among women with dietary intakes below 600 mg per day. Calcium supplements weren't independently linked with heart disease death. But women with dietary calcium intakes above 1,400 mg per day who also took supplements suffered from a higher mortality rate than women who consumed the same amount of calcium without taking supplements. This association appeared in a dose-dependent fashion. Which means that the more supplemental calcium this group of women took, the higher their risk for death. So there you have it. High calcium intake does appear to be linked with higher risk of death--from heart disease or any cause. But as this study shows, there isn't really a clear-cut formula for minimizing risk and maximizing benefit where calcium supplements are concerned. Total intakes between 600 and 1,400 mg per day appear to be perfectly safe. But obviously, it's important to consider how much calcium you're getting from dietary sources as well. So I'm going to stick with my usual recommendation for female patients: 500 mg of calcium in tablet form per day. For most women, this dosage is just enough to keep you well within the safe zone. |

| Ancient Aztecs believed this grain gave them supernatural ENERGY AND POWER... | |
| And maybe it did, in a manner of speaking. Yet, when the Spanish Conquistadors looted and ruined the ancient Aztec Empire, this nutritional treasure all but vanished with it. The Spaniards named the grain Salvia Hispanica L and then it was promptly forgotten. Well, so far it's just a colorful Aztec legend, right? But everything suddenly changed when... 500 years later, researchers finally started running tests... And when the first results came in, they nearly fell over. Because these seeds tested off the charts! The results clearly showed they had found a nutritional goldmine. And just for starters, this super grain turns out to be... |
