Infertility has been added to the list of health problems claimed to be caused by eating too much processed food, like takeaways, ready meals and pre-prepared snacks.
Men who eat more ultra-processed food (UPFs) take longer to get their partners pregnant, according to a study out this week. And when women do get pregnant, if they have a diet high in UPFs, their embryos develop more slowly.
But other experts have said the research is not convincing evidence that UPFs are really causing fertility problems.
“These results are not enough to action any change in behaviour in people ,” said Dr Channa Jayasena, a fertility doctor at Imperial College London. “Bombarding people [with diet advice] can make them miserable and stressed, which can aggravate fertility.”
