Meet the team behind Sigma Nutrition and discover our mission to bring clarity and credibility to nutrition science.
Founded in early 2014 by Danny Lennon, Sigma Nutrition is dedicated to providing objective, high-quality, evidence-based information on nutrition and health science.
Our mission is to serve as a trusted resource for dietitians, nutritionists, health and fitness professionals, researchers, and anyone deeply interested in the science of nutrition.
Through a diverse range of educational materials—including written articles, lectures, and our podcast Sigma Nutrition Radio—we aim to bridge the gap between cutting-edge scientific research and practical application.
For over a decade now, the podcast has become a go-to resource for those seeking thoughtful, evidence-driven discussions on nutrition and health topics.
Danny is the founder of Sigma Nutrition and host of the popular podcast Sigma Nutrition Radio since 2014. And he is the co-creator of the course Applied Nutrition Literacy with Dr. Alan Flanagan.
Danny is currently a member of the Advisory Board of the Sports Nutrition Association, the global regulatory body responsible for the standardisation of best practice in the sports nutrition profession. He is also an Advisory Board member of FoodFacts.org, a non-profit whose mission is to combat misinformation and pseudoscience in the nutrition field.
Danny has a master’s degree (MSc.) in Nutritional Sciences from University College Cork, in addition to a BSc. Degree in Biology and Physics (with concurrent diploma in education).
Along with Jordan Sullivan, he is the co-author of “Making Weight: The Ultimate Science Based Guide to Cutting Weight for Combat Sports”.
While his professional passion is nutrition science, it falls a long way behind his love for Arsenal, live music and dark, deadpan humor.
Alan Flanagan, PhD is a Postdoctoral Research Fellow at the University of Surrey, UK, where he previously completed a PhD in nutrition and a master’s degree in Nutritional Medicine. Dr. Flanagan is the founder of Alinea Nutrition, an online education hub dedicated to providing impartial, science-based nutrition reviews and analysis.
He has published in fields such as chrononutrition and research methods in nutrition (see publications).
Dr. Flanagan is a regular co-host of the podcast, as part of his role as Research Communication Officer at Sigma Nutrition.
