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.
Tofu is significantly associated with prostate cancer, but more research into this is required
EJACULATING AT LEAST 21 TIMES A MONTH SIGNIFICANTLY REDUCES THE RISK OF PROSTATE CANCER
Ejaculating at least 21 times a month significantly reduces a man’s risk of prostate cancer, research revealed in July.
This is compared to those who release just four-to-seven times every four weeks, a Harvard University study found.
The findings are true regardless of whether men achieve orgasm through masturbation or sex, the research adds.
Researchers did not speculate on why ejaculation protects against prostate cancer, however, past findings suggest it helps to rid the gland of cancer-causing substances and infections.
Ejaculation may also help to ease inflammation, which is a known cause of cancer.
