Legumes and Soy Foods Lower Blood Pressure Risk

The consumption of legumes and soy foods is associated with a reduced risk of developing high blood pressure.
Higher intake of legumes and soy foods, specifically at 170 grams and 60-80 grams per day, respectively, offers the most significant benefits.
Legumes and soy foods are rich in potassium, magnesium, and dietary fiber, nutrients known to support healthy blood pressure.
The analysis included data from 12 long-term observational studies conducted in the United States, Europe, and Asia.
Experts suggest that incorporating legumes and soy foods into one's diet could be a valuable strategy for mitigating the global burden of hypertension.

Legumes and Soy Foods: The Full Story Explained

A recent analysis published in the open access journal BMJ Nutrition Prevention & Health has shed new light on the relationship between the consumption of legumes and soy foods and the risk of developing high blood pressure. The study, which combined data from multiple countries, found that people who regularly consumed foods such as beans, lentils, chickpeas, tofu, edamame, and soy milk were less likely to develop hypertension.

The strongest benefits appeared at around 170 grams of legumes per day and 60 to 80 grams of soy foods daily. Legumes include foods like peas, lentils, chickpeas, and beans, while soy foods include tofu, soy milk, edamame, tempeh, and miso. According to the researchers, 100 grams of legumes or soy is roughly equal to one cup or 5 to 6 tablespoons of cooked beans, peas, lentils, chickpeas, or soybeans, or about a palm-sized serving of tofu.

Historical Context: Has This Happened Before?

Previous studies have linked legumes and soy foods to better heart health overall, but evidence specifically connecting them to lower blood pressure has been inconsistent. To better understand the relationship, researchers reviewed studies published through June 2025. The analysis included 10 published papers containing data from 12 long-term observational studies conducted in the United States, Europe, and Asia.

Nine studies included both men and women, while two focused only on women and one included only men. Study sizes ranged from 1,152 participants to 88,475 participants. Cases of high blood pressure ranged from 144 to more than 35,000. The researchers found a clear connection between higher intake of legumes and soy foods and a reduced likelihood of developing high blood pressure.

Legumes and Soy Foods: Economic & Real-World Impact

People with the highest legume intake were 16% less likely to develop hypertension compared with those eating the lowest amounts. For soy foods, the reduction in risk reached 19%. The researchers also looked at how risk changed depending on the amount consumed. For legumes, the risk reduction increased steadily up to around 170 grams per day, eventually reaching about 30%. For soy foods, most of the benefit appeared between 60 and 80 grams daily, lowering risk by roughly 28% to 29%.

The economic impact of hypertension is significant, with the World Health Organization estimating that the global cost of hypertension is around $370 billion annually. Incorporating legumes and soy foods into one's diet could be a valuable strategy for mitigating the global burden of hypertension. According to the researchers, current legume consumption across Europe and the UK remains far below recommended levels, with average intakes of only 8-15 g/day, far below the recommendations of 65 to 100 g/day recommended for overall cardiovascular health.

Expert Analysis & What Comes Next

Professor Sumantra Ray, chief scientist and executive director of NNEdPro Global Institute for Food, Nutrition and Health, which co-owns BMJ Nutrition Prevention & Health, said the findings add important support to research on plant-based diets and cardiovascular health.

The authors have significantly added to the case for using legumes and soy as primary dietary strategies to mitigate the global burden of hypertension.

The researchers also noted that unmeasured factors could still have influenced the results and that the plateau in soy benefits above 60 to 80 grams per day requires more research. Despite these limitations, the findings of this meta-analysis have major public health implications, given the alarming global increase in hypertension prevalence.
