Such DNA modification has been implicated in a child's future risk of obesity, diseases such as diabetes, and poor response to stress.
Headlines in the press reveal how these findings are often simplified to focus on the maternal impact: 'Mother's diet during pregnancy alters baby's DNA' (BBC), 'Grandma's Experiences Leave a Mark on Your Genes' (Discover), and 'Pregnant 9/11 survivors transmitted trauma to their children' (The Guardian).
