Does Miso Affect Blood Pressure? | Cooking with Yoshiko (2024)

It is true that miso can contain 200-300 milligrams of sodium per teaspoon, which is often a reason that people give when they tell me they do not want to have miso. But does miso really affect your blood pressure?

Recent research has shown that despite its high-sodium content,miso does NOT affect our cardiovascular system in the way that typical sodium-filled foods can. In recent animal studies, it was discovered that equal concentrations of salt (sodium chloride) from both miso and table salt each had different effects on blood pressure. It was found that while high-salt diets from table salt increased blood pressure, high-salt diets from miso had little effect towards blood pressure. In another study, it is reported that Japanese adults who implement a miso diet have a lower risk of cardiovascular issues, despite the sodium content. Although the relationship between miso and our cardiovascular system is still unclear, some researchers have speculated that the unique soy protein composition of miso (including peptide building-blocks of protein that get formed from soy proteins when the beans are fermented) is one of the major reasons miso is shown to support the cardiovascular system. Since miso is usually eaten alone, other cardio-supportive foods in miso soups and other miso flavoured dishes such as salad with miso dressingmay also provide an important role in these research findings.
