March is National Kidney Month and, with one in three Americans at risk for kidney disease, a good time for people to consider the health of this important organ. Kidneys play a vital role in your health by regulating blood pressure, controlling levels of salt and acid in the body, and filtering waste out of the blood. There are multiple factors that can affect a person’s kidney health, including diabetes, high blood pressure, and family history. To reduce the risk of kidney disease, the National Institutes of Health (NIH) recommends being more active during the day, eating foods with less salt, and baking food instead of frying it. Older adults can also check in with their doctor to monitor their blood pressure and blood-glucose levels, which can also affect kidney health.
