From Michael Allen, Ottawa, Ontario, Canada
The premise that people will overeat carbohydrates and fats in a protein-poor but energy-rich food environment is described in your article as a hypothesis (23 May, p 30). Fair enough, but the end of the piece says that all you need to do to achieve a healthy, satisfying diet is eat enough protein and top up with wholefoods, mostly plant-based. That sounds like Michael Pollan’s “eat food, not too much, mostly plants” advice, with a dollop of protein to take care of the “not too much” part.
To justify such prescriptive advice, the dietary hypothesis put forward by the authors will need long-term, prospective, comparative studies.
