E205: Here’s what sugar and zero-calorie sweeteners do to your body

May 17, 2023

Today we speak with an expert on sugar and things meant to replace it. The stakes are high. Very high. Sugar consumption in the population is astronomical and so is the use of sugar replacements. Knowing the impacts of both could help experts provide dietary guidance and help consumers make decisions. Dr. Robert Lustig is Professor Emeritus of Pediatrics in the Division of Endocrinology at the University of California, San Francisco. He specializes on the regulation of energy balance by the central nervous system; body weight regulation, appetite, metabolism, and is very well known for his work on sugar and their substitutes and on policies aimed at improving the diet of the population. A YouTube video on the effects of consuming sugar called “Sugar: The Bitter Truth,” has now been viewed 24 million times.

E202: Impact of non-caloric sweeteners on the microbiome – what we know now

April 13, 2023

With the widespread presence of artificial sweeteners in the food system, scientists and consumers want to know about their safety. Safety concerns have been expressed for years, and lots of research has been done, but relatively new on the scene is work examining the effect of sweeteners on the microbiome. This interview is part of a series on the impact of artificial sweeteners. Our guest today, Dr. Jotham Suez, is doing fascinating work on this topic. He’s Assistant Professor of Molecular Microbiology and Immunology and the Public Health Johns Hopkins University.

E196: Why do we need zero calorie sweeteners, and are they safe?

February 23, 2023

Artificial sweeteners, known more recently as non-nutritive or low-calorie sweeteners, have been a source of great hope. What could be better than enjoying sweetness in foods but without the calories? Sucralose, xylitol, stevia, saccharin, aspartame, there are a lot of them out there. You may add them to food yourself, you may consume them in beverages, and if not, there’s a good chance they’ll show up in foods that you buy. But, do they work and are they safe? Few know this area like Dr. Richard Mattes, distinguished Professor of Nutrition Science at Purdue University.

E194: Foodborne illness and the struggle for food safety

January 25, 2023

When I was growing up, people didn’t fret much about food safety. Trichinosis from undercooked pork was about all I heard about. But today people hear about much more: norovirus, salmonella, campylobacter, staphylococcus, listeria, and there’s much more. So what in the world is happening? Our guest, Timothy Lytton, distinguished university professor and professor of law at Georgia State University knows an awful lot about this. He’s the author of a seminal book entitled “Outbreak: Foodborne Illness and the Struggle for Food Safety.”

E170: Why the US Must Reduce Sodium Intake: It’s Costing Lives

June 10, 2022

Today, we’re going to talk salt with Dr. Michael Jacobson, former president and co-founder of the Center for Science in the Public Interest. Dr. Jacobson is one of the authors of an important article published recently in the journal Hypertension. The article comes to a startling conclusion that delays in implementing voluntary sodium reduction targets by the food and restaurant industry may result in nearly 265,000 preventable deaths between 2017 and 2031.

E159: Ultra-processed Foods Have Addiction Impact on our Bodies

March 17, 2022

Much has been written and said about ultra-processed foods, first in scientific circles and now more broadly in the media. This concept is relatively new, but what is even newer in this discussion is how such foods figure into the issue of food and addiction. Our guest, Dr. Ashley Gearhardt is doing pioneering work on this. So, we eat a lot of these foods. A paper published several months ago, found that as much as 80% of all calories consumed in the US and in Canada come from such foods. Such diets are high in added sugar, in fat and saturated fat and low in fiber and key vitamins and minerals. We’ve recorded earlier podcasts on ultra-processed foods, most notably with Dr. Carlos Monteiro, who created the term. But now let’s talk addiction. Ashley Gearhardt is Associate Professor in the department of psychology at the University of Michigan and as a leading expert on the issue of food and addiction.

E155: How Industry and Farming Practices Contribute to Antibiotic Resistant Superbugs

February 3, 2022

Antibiotic resistance has long been considered one of the greatest threats to global health. More recently, we’re seeing growing public awareness around the overuse of antibiotics used in the US livestock system – a system that produces much of our meat supply. Widespread antibiotic use on US farms has evolved from something that only a small group of advocates and scientists worried about to something many more people are talking about now. The term antibiotic free is showing up on products and supermarkets and the way fast food chains are advertising their products. With drug resistant pathogens or superbugs, as some people know them, now being called the slower moving pandemic, it’s time to check in on both how the science and the policy are evolving in this important part of our food system. And there’s no one better than our guest to help deal with this. Dr. David Wallinga is senior health officer for the Food, Agriculture and Health, Healthy People & Thriving Communities Program at NRDC, the Natural Resources Defense Council, a leading environmental organization. David is a physician, and has led the way on connecting science with policy in the area of food and environment. He is highly regarded for his work on antibiotics and the food supply.

E146: Organic Vs Regenerative Agriculture – What You Need to Know

October 19, 2021

So what does it mean for something to be considered organic, or to be considered regenerative or sustainably produced? Defining these concepts in agriculture production and in food labeling is complicated, but very important. So government defines and oversees certain terms, while other terms are generally overseen by producers, by industry experts, or even by non-governmental organizations. The politics and governance structures of labeling can be very important in how sustainably produced goods are made and marketed. In today’s podcast, we’ll speak with Dr. Samantha Mosier, political scientist on the faculty of East Carolina University, as part of our Regenerative Agriculture podcast series.
