A new study has suggested that following an oestrogen rich diet similar to that of gorillas or colobus monkeys may help reduce the risk of certain cancers though over indulgence may result in reproductive problems.
Phyto-oestrogens are plant chemicals that function like the female sex hormone. In foods like soy and red clover they may protect us from oestrogen-dependent cancers - a group that includes breast and colorectal cancers, New Scientist reported.
AdvertisementQuite often, the potential health effects of phyto-oestrogens are studied, but nobody has looked at if humans are the only primates with a taste for plants containing the chemicals, said Michael Wasserman of McGill University in Montreal, Canada.
If other primates eat them, it might indicate that we have evolved to cope with them in small doses.
However, Katharine Milton of the University of California, Berkeley insisted that the sex hormone mimics could have a downside.
"Oestrogens are potent chemicals; if you're taking them in excessive amounts, this can interfere with your reproductive physiology," Milton said.
Wasserman, Milton and colleagues examined the diets of mountain gorillas (Gorilla beringei) and red colobus monkeys (Procolobus rufomitratus) in a national park in Uganda.
They discovered that 10.6 per cent of plants in the colobus diet and 8.8 per cent of those in the gorilla diet consituted phyto-oestrogens.
The study has been published in the American Journal of Physical Anthropology.
