In this episode, Greg Dickens and I discuss recent news on how antibiotics during labour affect a child’s long-term health, on how our brains continue to develop into our early thirties, on how astringent flavours help us learn, and on how adverse childhood experiences affect fitness in adulthood. We then talk about football - why it’s great for children, why industrialised football poses some very specific risks, and how parents can navigate the risks so children can get the benefits of sports. Finally, we talk about why high-salt diets contribute to metabolic syndrome.

“In the United Kingdom, where universal screening is not currently implemented and the background rate is much lower than it was in the United States before screening was implemented, it is estimated that 440 women need to receive IAP to prevent 1 case of EOD, and 3000 to prevent 1 case of EOD leading to death or severe disability.” https://www.ajog.org/article/S0002-9378(22)00622-6/fulltext
