Great discussions from leading experts but sadly fail to demonstrate the humility needed as true scientists. The scientific method requires constant evaluation and at any time will be only partially βcorrectβ representation of the truth.. They weaken their stance by suggesting they are the only source of truth, whilst failing to understand the wider role of food in peopleβs lives.
I have not lissoned to this so bast on the reviews
Evidence based, nuanced, no hype. Expert interviews, deep dives, detailed and clear explanations. My go-to source for all nutrition questions. Having listened to well over 100 episodes, Sigma has easily become my favorite podcast. Danny is an exceptional interviewer, and he and Alan have a talent for cutting through the confusion to tease out what the science really shows (and how/why). Iβve grown in careful, critical thinking in all spheres of life. Highly recommend.
