Dietary habits and hypertension: Salt reduction and legume intake

Recent nutritional findings highlight the impact of diet on hypertension and cardiovascular health. In Japan, an analysis of national health surveys identifies cup noodles and instant ramen as the top sources of high salt intake, followed by pickled plums and various salted seafood products. Experts suggest that since approximately 70% of salt intake comes from seasonings, individuals can manage blood pressure by reducing soy sauce and salt while using spices, herbs, and citrus to maintain flavor.

Complementary research published in BMJ Nutrition, Prevention & Health suggests that increasing legume and soy consumption can significantly lower hypertension risks. A meta-analysis of studies across Asia, Europe, and the United States indicates that high legume intake can reduce hypertension risk by 16%, while high soy product intake can reduce it by 19%.

The study recommends a daily intake of approximately 170 grams of legumes and 60 to 80 grams of soy products to achieve maximum benefits. These foods are believed to aid blood pressure regulation through their content of potassium, magnesium, dietary fiber, and isoflavones.
