A study published in the British Medical Journal looked at the diets and overall health of 92,915 Japanese men and women aged 45 to 74 for an average of 15 years.
The researchers found that those who frequently ate miso, tempeh, soy sauce and natto, a gooey dish made from fermented soybeans that is popular in Asian countries, benefited from a lower risk of mortality.
The study examined how much fermented soy needed to be consumed in order to see benefits.
It found that men who ate at least 50.2g per day of fermented soy were 10 per cent less likely to die in the 14.8 years after compared to those who ate the smallest amounts of fermented soy products.
Women saw the same benefits from eating at least 46.6g per day.
Consuming natto alone led to health benefits, too.
The study found that eating at least 26.2g of the dish every day led to a 24 per cent lower risk of death from cardiovascular disease for men and 21 per cent lower for women.
The authors suggested that the benefits of fermented soy products could be down to their high fibre content. They are also rich in potassium.
But the researchers said that various unmeasured factors could have influenced the study’s results, so more studies are needed in order to establish cause and effect.
Nonetheless, co-author Dr Norie Sawada of the National Cancer Centre in Japan said that he would recommend consuming fermented soy for its impact on cardiovascular disease, which is the leading cause of death in the USA.
In the UK the leading cause of death is still cancer.
