Research suggests that eating tofu and other soy-based foods may improve heart health. Consuming soy-based foods, such as tofu, may provide cardiovascular benefits, according to new research.

New research suggests that eating tofu and other soy-based foods may reduce the risk of coronary heart disease.

The findings, which feature in the journal Circulation, give more information on the health benefits of isoflavones, a type of compound that occurs naturally in some plant-based foods. Soy-based foods, such as tofu, are rich in isoflavones.

Soy controversy

In 1999, the Food and Drug Administration (FDA) approved labeling on soy-based products that stated that eating soy-based foods reduced the risk of coronary heart disease. However, since the approval, studies on the health benefits of soy-based foods have shown mixed results.

As a consequence, in 2007, the FDA announced that they would be reviewing the evidence on soy-based foods and heart health. In 2017, they proposed revoking the health claim that soy-based foods reduce heart disease, given the conflicting evidence that their review found.

The present study intervenes in this debate, hoping to provide more information on the relative benefit of soy-based foods for heart health.

Gaining a more detailed understanding of nutrition and heart health is important because, as the Centers for Disease Control and Prevention (CDC) note, ìHeart disease is the leading cause of death in the United States.î

Three major studies

The study drew on data from three separate studies that included a total of 168,474 women and 42,226 men, and each tracked the participants for more than 20 years. Participants were all free of heart disease and cancer at the beginning of the studies.

Every 2ñ4 years, the participants received a nutrition survey to complete. The researchers obtained their heart disease information from medical records or from death certificates in the instances where a person died due to heart disease.

The study took into account various confounding factors that may also affect heart disease to try to identify precisely how isoflavones affect heart health.

Moderate benefits of isoflavones

After analyzing the data, the study found that, in general, a higher intake of isoflavones was associated with a moderate reduction in the risk of heart disease. This link was also true for tofu when the team looked at this food independently.

The study also found that the benefits of eating tofu were particularly apparent for women before menopause. After menopause, the researchers only noted a clear association between tofu consumption and reduced heart disease risk in women who were not taking hormone therapy.

While the study suggests an association between tofu and isoflavones on the one hand and reduced risk of heart disease on the other, it is not clear why or how the relationship between them works.

Dr. Qi Sun, an associate professor in the department of nutrition at Harvard University, MA, and lead author of the study says: Despite these findings, I donít think tofu is by any means a magic bullet. Overall diet quality is still critical to consider, and tofu can be a very healthy component.
