Cutting salt from our diets has been dogma for many years. Yet there is not very much evidence to support the extreme efforts some people make.

How Good Is the Evidence for Cutting Salt?

Duration

For decades, public health experts have been admonishing Americans to cut the salt in our diets. In fact, the American Heart Association recommends that we limit ourselves to 2,300 mg of sodium daily. That’s about one teaspoon. Ideally, the AHA says, we would get less than 1,500 mg of this crucial mineral every day. 

Should You Be Cutting Salt?

Why is salt such a problem? People who consume large quantities of salt tend to have high blood pressure. When they reduce their sodium intake, their blood pressure often drops. But what about people who get ordinary amounts of salt in their food? Should they be struggling to cut back?

Dr. Aaron Carroll is very conscious of the medical evidence for such recommendations. Surprisingly, what he says about salt restriction is that there isn’t very much scientific data to support it. Because it has been dogma all these years, it sounds like heresy to suggest that cutting back on salt might not make very much difference for most people and could even be harmful for a few. Have health care providers embraced other recommendations despite a paucity of evidence? Call in your questions or observations: 888-472-3366 between 7 and 8 am EDT on Saturday, April 13, 2019.

Side Effects of Gabapentinoids:

Doctors have recently started prescribing one group of medicines far more frequently than they once did. The gabapentinoids (gabapentin and pregabalin, aka Neurontin and Lyrica) were originally introduced as anticonvulsants. However, doctors now prescribe them widely for serious pain conditions on the assumption that they are safer than opioids. What evidence do we have for their effectiveness for pain. In addition, just how safe are they?

Tom Moore of ISMP shares the results of the latest QuarterWatch on dangerous adverse effects of these medications. Call in your questions and stories about gabapentin or pregabalin: 888-472-3366 between 7 and 8 am EDT, 4/13/19. Or send us email: radio@peoplespharmacy.com
