Eating nuts while breastfeeding – the Nuts For Babies Study.

INTERVENTION: Maternal consumption of at least 60 peanuts and 40 cashew nuts per week from birth until 6 months post‐natal. Participants will purchase their own peanuts and cashew nuts. Every 2 weeks during the intervention period, the women will be sent a mobile phone text with a link to complete a quick survey about how much peanut and cashew nut they have eaten over the past week, and whether they would like any further advice and support regarding their allocated nut diet. This will also include one question on their breastfeeding status.
