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.

E198: Why SNAP pandemic benefits for college students should continue

March 7, 2023

There has been increasing attention to the issue of food insecurity among college students. Estimates vary, but to provide some perspective, one report found that a staggering 30% of all college students experienced food insecurity at some point in their college careers. In response to the COVID-19 pandemic, the US temporarily extended the Supplemental Nutrition Assistance Program benefits to college-aged students. But now this pandemic help is set to expire, impacting more than three million college students who have relied on this program for food. Today we speak with Heather Taylor, a former US delegate to the United Nations, and now managing director of Bread for the World. Having experienced severe food insecurity as an undergraduate student at Georgetown University, she now advocates for SNAP expansion for college students and other marginalized groups facing food insecurity.

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.
