About This Episode:
In the last couple of decades, carbohydrates have experienced an increasing amount of negative campaigning. In general, the main argument is that carbohydrates have been viewed as the root cause for obesity, diabetes and several other diseases including heart disease and behavioral disorders. However, there can often be a lack of appreciation that not all carbohydrates are equal in their health effects.
Beyond this, now there has even been confusion as to whether high fiber diets with whole grains are good for you or bad. This is mostly a result of strong claims made by people with large online followings and promoting specific diets.
What does the best evidence tell us about different carbohydrate types and impacts on health outcomes? Should carbohydrates be viewed as inherently harmful? How solid is the evidence on whole grains, legumes and other high-fiber carbohydrate-rich foods?
To help us tease through the science in this area, in this episode we get some answers from nutrition epidemiologist, Dr. Andrew Reynolds.
About the Guest:
Dr. Andrew Reynolds is a nutrition epidemiologist working with achievable lifestyle and environment change in the prevention and management of non-communicable diseases, such as type 2 diabetes and cardiovascular disease. He primarily conducts randomised controlled trials and meta-analyses. Much of his work is to inform evidence-based dietary or clinical guidelines, policy, and food reformulation.

| 0:00.0 | Hello and welcome to Sigma Nutrition Radio, the podcast that brings you discussions all about nutrition, science and health. My name is Danny Lennon. |
| 0:22.8 | You are very welcome to the show. We're at episode 482 of the podcast today. Thank you to everyone |
| 0:29.6 | who's given feedback on our previous episode, which was a premium exclusive episode that was |
| 0:34.6 | available in full on our premium feed of the podcast if you're a premium |
| 0:38.5 | subscriber. Otherwise, you can hear a 20 minute preview here on the public feed, if you |
| 0:43.1 | do listen to it, where we asked the question, is personalized nutrition actually better than |
| 0:48.4 | just general nutrition advice? And we dived into some of the claims about personalized nutrition, |
| 0:54.0 | some of the evidence that's |
| 0:55.2 | being published in that field, and asked, does this actually match up? So I hope you go and listen |
| 1:00.3 | to that episode, whether you even catch that 20 minute preview, or if you go and subscribe to |
| 1:05.7 | Sigma Nutrition Premium and catch these full premium exclusive episodes in their entirety. So that was on the previous |
| 1:12.8 | episode of the podcast. Today, we're going to be talking all about carbohydrates and human health, |
| 1:18.4 | an area that, of course, has a lot of conflicting information, particularly when you go online |
| 1:23.8 | from a variety of claims about what carbohydrates may do. But again, what we try and do here |
| 1:29.9 | is take a nuanced look at some of the details under the hood and essentially dive into some |
| 1:34.5 | literature in that area. To help us do that today, I'm going to be talking to Dr. Andrew Reynolds, |
| 1:40.7 | who is a nutrition epidemiologist working with lifestyle and environmental change, |
| 1:47.3 | particularly focused on dietary changes and how that may have impacts on the prevention or |
| 1:53.3 | management of chronic diseases, so things like type 2 diabetes, cardiovascular disease. |
| 1:58.6 | And a lot of his work focuses either on randomized control trials or |
| 2:02.9 | meta-analyses. And we're going to mention a number of these today, particularly some of the |
| 2:06.9 | systematic reviews and meta-analyses he's published on a variety of topics related to carbohydrates. |
