As a PhD and Registered Dietitian I really appreciate the quality, thoroughness, and objectivity of Sigma Nutrition Radio. In a sea of sensationalism, clickbait and misinformation, SNR is a breath of fresh air. Danny and Alan are very thorough and do an excellent job of explaining studies and summarizing key points. They don’t push their personal agenda and have achieved a true evidence-based podcast. I can’t recommend this podcast enough.

Great nutrition content

I use to find the podcast interesting and informative but have since parted ways due to the high level of arrogance. Episode 400 is a great example of this. The hosts seemingly cherry picked controversial statements made by the “quacks” and then proceeded to mock them based on little supporting evidence. I had never heard of the quacks mentioned so I have no skin in the game, but I found the ad hominem attacks off putting and unhelpful in communicating why I should think of these people as quacks

Used to be better but now everything is either very shallow or hidden behind a paywall.

Learn from people who care to get it right.

This is one of the most evidenced informed podcast on nutrition. The thing I couldn’t get past is the delivery of the content by these guys. They come across as pretty pretentious and there’s an element of academic snobbery. I hope they can change the delivery of their message.

The purpose of this podcast is not to provide information. It’s just people chatting about nutrition. They obviously have a lot of information to share but they bury it under lots and lots of extra words.

Really informative. I learned a lot. Not dogmatic. I am based in the US and like that Sigma Nutrition is based across the pond, which provides a different perspective.

This is the only podcast to get the most and latest nutrition education for everyone. It does focus on athletic performance based nutrition but pertinent information for everyone interested in the evidence based nutrition practices. Danny is so knowledgeable and prepared when he interviews his guests. Often times the guests comment on his great questions and how knowledgeable he is on the topics being covered. Highly, highly recommend this podcast.

I really enjoy listening to the shows. I’ve logged in plenty of bike riding miles with Danny learning some really interesting things. Not being having a nutrition background I’m addicted to the next show! Thank you.

Once upon a time they offered good information and now without just a tacky show of mockery, terrible

I appreciate that this podcast explores the middle ground rather than exploit the black and white thinking around nutrition science! I also appreciate the quack asylum. As a clinical dietitian working in Cleveland Ohio, I personally experience the harm of the dietary advice influenced by Dr. mark Hyman, Dr. Caldwell Esselstyn, and Dr. Michael Roizen. Nutrition is a fluid changing state based on many factors, and not a one size fits all approach. Keep up the good work!

This is a great podcast for balanced, evidence-based information on nutrition. Love this podcast!!

It was a lot better when Danny didn’t have a cohost. Alan is a smart guy but I find myself dozing off when he speaks. Also annoying how he espouses his political views often. I loved when it was just Danny having different guests each episode with topics in their area of expertise.

Alan needs to keep his political and religious beliefs out of the podcast. Take your own advice and stay in your area of expertise

When I first saw the title of episode #336 Ethics of Veganism and Omnivorism, I was very excited for some deep discussion, especially since the guest is a philosophy professor at Princeton, and because I do not think factory farming is morally right. However, after listening to the episode, I was left disappointed to hear that a supposedly highly educated professor of philosophy presents the same basic arguments made by many misinformed online diet zealots. At one point, he presents the idea that holistically raised animals that are killed in middle age somehow increases suffering. This insinuates that a longer lifespan decreases suffering. This is a false claim, since longer lifespans, for both humans and animals, do not equate to less suffering. Simply explore the long life span, yet increased prevalence of chronic disease of later life common in the US population. Why is it that Danny and his guest are quick to attack the industrial animal industry, yet not once do they mention the equally unsustainable, unhealthy model of monocrop agriculture industry. A second point the host and guest seem to completely avoid is the fact that organisms across the animal AND plant kingdoms are sentient, on a relative scale. True, that a ruminant animal has a much more complex nervous system then a cabbage leaf, but not once is this talked about. They don’t challenge the idea that plants can also “feel” and are therefore, capable of some degree of suffering. The argument never dives into the moral dilemma that life eats life. A true philosophical exploration into a fundamental conundrum such as this would have been worth discussing. The philosophy professor really shows his true bias when he cites one study that athletes don’t need protein from animal sources for adequate nutrition. While this is acceptable, this argument on nutrition does not belong in an ethical debate. Why is a philosophy professor even presenting nutritional scientific information? It’s almost as if he is trying to prop up the superficiality of his ethical arguments with a single, arbitrarily chosen study. There should have been more talk on how we define animal/plant suffering from a neurophysiological standpoint and it’s considerations in food choices (some marine bivalves have been shown to have less complex nervous systems than plants, possibly challenging the professor’s entire argument on which causes more suffering, eating plants or animals). Not only that, but does the killing and suffering of countless gophers, moles, rabbits, insects, and bugs as a cost of crop harvesting, outweigh the killing of a single beef cattle that can feed 2-3 people for a year? Lastly, the professor makes the claim that we should avoid eating animals because, as I prosperous society, we have the ability to eat a vegan diet, unlike many tribes around the world. This is an arrogant statement that seemingly borders on making the claim that the westernized world is superior to these “meat-eating” cultures. A thoughtful professor would address the fact that for the entire 1.3 million years as Homo sapiens, no anthropologist has found a purely vegan culture throughout history. Does this make modern day humans morally superior to those in the past? This type of thinking seems to be so pervasive in many important discussions today, but it especially runs unchecked in our university systems in the US. I propose a debate format next attempt. When we start out with a predetermined conclusion presented by an obviously biased viewpoint, it doesn’t help anyone. Debate is a critical way, if not the most critical way, we can advance important ideas like these. Thank you to Danny for attempting to cover this topic. We need more discourse in this arena.

At this point, I've probably listened to over 1000 hours of podcast episodes on the subject of health and human performance, most of them centered around the topic of nutrition. I've always tried to limit my listening to presenters who relied on what appeared to be a careful review of the scientific literature on the subject. Recently, I have begun to take a short program in clinical epidemiology through the Imperial College of London. The things that I have learned there have caused me to revisit some of my own recent blog posts that I had hoped were a careful analysis of research literature. I realized that there were many things that I had not understood before I begin my formal study of epidemiology. Now, I have come to the somewhat sad conclusion that even some of the more trusted names in the world of health oriented blogs and podcasts either don't properly know how to interpret research or, even worse, are willfully cherry-picking information that is designed to promote their products, books, get them speaking engagements and advertisers etc. So, I searched specifically for podcasts on the topic of clinical epidemiology and soon found this one. I can't say too much about how impressed I am with the work they are doing at Sigma nutrition. It really is the most unbiased and detailed review of the scientific literature on health and fitness, especially in the area of nutrition. In addition to the excellent podcast, I highly recommend reading the Sigma statements on their website. If you really want to understand what the evidence says about diet and health, these statements are undoubtedly the best resource currently available for the educated layperson.

By far the best podcast on nutrition and performance if you really care about learning and understanding nutrition and its impact on our body and health. Danny conducts high quality interviews with top experts in the field of nutrition. Content is based on real research, which I tremendously value. Sigma Nutrition dives into current and relevant nutritional topics. Highly recommended. Cutting edge content. Great host.

Danny is a first rate interviewer and has excellent guests. Many nutrition and fitness podcast claim to be “evidence based”, but Sigma truly walks the walk with a deep appreciation and understanding of science.

Whether you’re already deep into your journey of authentic health, or just getting started organizing your lifestyle around what matters most - this is a must-listen podcast for you! Danny does an incredible job leading conversations that cover a huge breadth of topics related to the ins and outs of navigating the ever-changing health and wellness landscape - with concepts rooted in evidence-based research. Highly recommend listening and subscribing!

I absolutely enjoy listening to this podcast. Everyday while I drive, I have Sigma Nutrition on. I get to learn about different health, fitness and nutrition topics. Danny’s questions are always on point. I also appreciate how Danny responded to my questions whether it be email or Instagram. Very cool show, and I also like the music that the show starts with. I’m really glad I discovered this podcast thru Rebecca Nolan on Instagram, who’s also a wealth of knowledge! Thanks to the show, I am developing an interest in resistance training, and now have a goal of getting stronger! Kudos to you Danny!

What I love most about the Sigma Nutrition podcast is that Danny's passion for nutrition and learning comes through in every episode. His guests are thought leaders in their fields and he guides listeners through complicated topics with relevant and well thought out questions. I just discovered the podcast, but am slowly making my way through all the previous episodes, while staying current on the new ones coming out. Thank you Danny!

Danny Lennon is well-informed and can ask questions of his experts as a peer and from a layperson’s perspective—whatever it takes to tease out the information needed. His guests are top-notch, and he lets them answer the questions at length.

Danny has time and time again astounded me with the quality of his content and the remarkable evidence based incite he displays on this podcast. I can’t say enough good things about it. I recommend it to everybody I know!

I never regret spending my limited learning time listening to Danny and his guests. Very few do it so well.

I stumbled upon this podcast in an effort to find quality, evidenced based health information. I am not in the industrty but am constantaly amazed at the lack of real scientic data related to health and well being. Danny is clearly well read and knowledgeable, way beyond my understanding somtimes. I love his style of interviewing, and you can tell he really does his homework for each episode. Since I am not in the field, nor an elite body builder, I will sometimes skip epidoes that don't pertain to my interests, but that is the beauty of this podcast, there is a wide variety of guests and topics. Keep up the great work! And thank you.

I am sorry I just found SigmaNutrition - I'll certainly be binge-listening until I catch up. Danny Lennon is articulate and easy to listen to. Combine that with his knowledge and his fabulous interviewing skills the conversations with his guests are enlightening and entertaining. I'm a fan!

Fantastic guests covering a range of topics. Objective, not pushing any particular viewpoint. Would never have guessed there would be so much content for nutrition but somehow they've kept this up for 300 episodes and it's still fresh !

I love this podcast. The topics are intriguing, the guests have great info & perspectives, and Danny is an excellent, excellent interviewer. His questions are so clear and insightful. He really understands what the listener would want to hear, and, of course, he’s super knowledgeable himself. While this podcast favors the scientific method, it’s not overbearing or righteous. It has a very inclusive feel - you get the sense that the mission is to bring all the resources for better health all around, not just to be correct for its own sake. Although, no worries, there’s plenty of substantiation for what’s presented, too. Why are you reading this review now and not picking out episodes to binge? Go!

I’ve been listening to this podcast for a long time and I am truly appreciative of the content that Danny presents and his format. If you’re a health and wellness practitioner take the time to listen. If you’re a client of this field, use it to stimulate better service from your practitioner. Wonderful stuff, thanks Danny!

The wealth of information that Danny brings is invaluable to me as a sports and nutrition coach. I particularly like the holistic approach - the podcasts don't focus only on nutrition; they include all the valuable ancillary information and analysis.

So glad I found this.

Danny has created an incredible podcast where people can learn from top professionals (including himself). Thank you for putting out quality content and helping common people like myself understand the science of nutrition. I guarantee you don’t get the praise you deserve, and I’m sure it’s frustrating to put so much work into a science that people with larger followings disparage and misconstrue for their own financial gain. Just know that there are many people like me who genuinely appreciate the content that you put out!! You are helping tilt this twisted nutrition world into a better position, and that is an amazing accomplishment!

Danny, Where do I start? As an Owner of a Personal Training Company with my wife, we pride ourselves on staying up to date with the latest science, and data, and I can say your podcast is a HUGE reason we are informed. Please keep putting out great content. I love it and I know so many others out there do too!

You bring some really intelligent researchers into your podcasts and ask them great questions, keep it up and I appreciate your work!

I think Danny is great...knowledge, interviewing skills, the right mindset. Don’t care too much for the recent episodes on “elite” athletic performance. Maybe some of it translates to us normal people, but elite athletes are just a very tiny fraction of us.

Always look forward to your Podcasts, Danny. Just listened to Louise Burke on Project Supernova: the Science of Fueling Elite Athletes. looking forward to the studies being published.

Sigma Nutrition is without a doubt one of the leading evidenced-based training and nutrition resources - exceptionally high quality and value add content. Danny continues to interview every major thought leader in the ecosystem and you will quickly learn how much he loves his work and the extreme level of personal responsibility he feels for sharing accurate information. This podcast has been instrumental in teaching me the fundamentals of healthy, intelligent and efficient bodybuilding. Well done! Keep up the phenomenal work.

One of the best podcasts to educate yourself on various topics of health and nutrition.

Sigma was the first podcast I stumbled across a couple of years ago and it remains one of my favorites. I just today went back and listened to #157 and it speaks to me totally different from when it originally aired. Love all of the content and it helps me stay at the top of my game mentally and physically.

Just finished listening to the menopause-estrogen podcast and ordered the book Estrogen Matters. Great episode! This is the primary population I work with and am anxious to read the science the authors studied. Keep up the great work.

I learn a lot from listening to this podcast. Excellent evidence based show. I appreciate the diverse opinions presented. The host is an excellent interviewer and helps bring the best knowledge out of the guests. Two or three times per episode the host will offer a concise recap of the material discussed; though it’s very succinct, it really helps drive the topic home in an understandable way (my favorite part).

Love the knowledge and evidence based research shared on this podcast. Definitely worth the listen!

Great and much needed information however, his choice of language (profanity) took away from us getting what we need.

I love that this show focuses on the science of nutrition and fitness. There are too many shows where the guests sound more like salespeople than experts in any field. Finally a show with integrity.

Danny kills it, as always. I deeply needed show with very high quality nutrition information straight from the experts mouth's. Very few podcasts feature so many actual nutrition scientists, Danny and SN stand alone here. 5 stars and 3 cheers.

Such a great show. Danny is a great interviewer and the guests are outstanding. Be prepared to learn and be entertained at the same time. Keep up the amazing work Danny!!

Listen to this one. It is.. incredible.

The Sigma podcast is by far the best nutrition-related podcast I’ve come across. Danny has an exceptional gift for taking nutrition concepts and clearly communicating them in practical ways. His guests are outstanding and an incredible wealth of high-quality evidence-based knowledge. If you are a nutrition or fitness professional at any level, you need to do yourself and your clients a favor and listen to every episode.

Look forward to these podcasts each week. I actually stumbled across it a year ago and have listened back to every single episode. Danny is a great host and does an impeccable job of guiding the conversation, recapping key points, and asking great follow up questions. Can’t recommend this show enough.
