Tofu is significantly associated with prostate cancer, a study reveals, however, experts stress ‘much more research is needed’.
Plant-derived compounds known as phytoestrogens, which are mainly found in soy products such as tofu and edamame beans, have previously been linked to the condition due to them being structurally similar to a hormone that increases the disease’s severity.
Lead author Dr Jianjun Zhang from Indiana University, said: ‘Our study offers novel evidence that dietary intake of isoflavones [a type of phytoestrogens] has different effects on advanced and non-advanced prostate cancer.’
Yet, other experts argue much more research is required to determine soy’s prostate cancer-effects before it can be reliably linked to the condition.
Prostate cancer affects around 11 percent of men at some point in their lives. Due to it being slow growing, treatment is not necessarily required if the patient suffers no symptoms.
