A mother's diet around the time of conception can permanently influence her baby's DNA, research suggests.
Animal experiments show diet in pregnancy can switch genes on or off, but this is the first human evidence.
The research followed women in rural Gambia, where seasonal climate leads to big differences in diet between rainy and dry periods.
It emphasises the need for a well-balanced diet before conception and in pregnancy, says a UK/US team.
