Protein is a health and fitness buzzword – plastered on packaging, prioritised in diets and praised by fitness influencers. But is our preoccupation with protein overshadowing another nutritional essential – fibre? Ruth Alexander explores the science, and marketing, behind protein’s popularity with expert guests: Dr Emma Beckett, a food and nutrition scientist and communicator in Australia, and author of “You are more than what you eat”; physician and social media creator Dr Karan Rajan, who’s authored "'This Book May Save Your Life”; Scott Dicker from SPINS market research company in Chicago; Paul Kita, deputy editor of Men’s Health Magazine in the US.
