Why do Japanese people live longer? A reason might be tofu and miso. Japanese scientists studied the health benefits of soybean products. People who ate tofu and miso were 10 per cent less likely to die from diseases. Soybean-based food cut the risk of death from heart attacks, stroke and other cardiovascular problems.
