As healthy as miso soup is, there is one attribute that scares some people away from this Japanese classic. Indeed, the average teaspoon of miso is known to have between 200 and 300 milligrams of sodium, making it a fairly high-sodium food. If you are on a low-sodium diet, this can sound like a bad thing. Fortunately, the truth is not so simple.
Scientific studies have shown us that miso does not have the impact on your sodium levels that its sodium content may indicate. One group of laboratory animals were fed miso, while a second group was given an equal amount of sodium in the form of ordinary salt. The animals who were fed miso did not exhibit an increase in blood pressure. Additional studies on humans reinforced these findings, and showed that Japanese people who regularly eat miso actually exhibit greater cardiovascular benefits.
It is not known why miso has such a counterintuitive effect on your blood pressure. However, it remains clear that the dish is a healthy addition to any diet. Consider enjoying a bowl on your next visit to our Seattle Korean restaurant.
