Legumes and soy consumption linked to lower blood pressure risk

A recent study published in the BMJ indicates that higher consumption of legumes and soy is associated with a reduced risk of developing high blood pressure. The research analyzed data from 10 research groups involving 309,853 participants across regions including the United States, Asia, and Europe.

Findings show that individuals with the highest intake of legumes faced a 16% lower risk of hypertension compared to those with lower intake. The greatest reduction was linked to a daily consumption of approximately 140 grams of legumes. Similarly, high soy consumption—including foods like tofu and edamame—was associated with a 19% lower risk, with benefits stabilizing at around 70 grams per day.

Researchers attribute these benefits to nutrients found in legumes, such as beans, lentils, and peas, including potassium, magnesium, and fiber. Potassium helps the body eliminate excess sodium, while magnesium supports muscle and vascular functions. Soy also contains isoflavones, which may improve vascular function.
