A study published in the BMJ looks at chips, potatoes and whole grains and type 2 diabetes risk.
Comment from our colleagues at the Spanish SMC:
Cristóbal Morales, Specialist in Endocrinology and Nutrition, Vithas Sevilla Hospital, said:
“The study is rigorous and well designed. Although it cannot prove causality, it provides valuable and already known evidence that supports current recommendations to prioritize whole grains and limit fried foods, even when it comes to options that may initially seem “healthy” such as potatoes. A clear message: preventing type 2 diabetes starts with adopting and maintaining healthy lifestyles and nutrition.”
‘Total and specific potato intake and risk of type 2 diabetes: results from three US cohort studies and a substitution meta-analysis of prospective cohorts’ by Seyed Mohammad Mousavi et al. was published in the BMJ at 23:30 UK time on Wednesday 6 August 2025.
