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

E201: Junk Food Politics – the price of outsized corporate influence
Processed food industries are thriving in developing countries, despite government commitment to eradicating non-communicable diseases, prevention programs aim at reducing obesity, type two diabetes, and sugary beverage consumption. What’s more, political leaders in some countries are reluctant to regulate the marketing and sale of these products, particularly among vulnerable groups, like children and the poor. Like me, you might be asking yourself: why? Our guest today is the author of a new book, “Junk Food Politics: How Beverage and Fast Food Industries Are Reshaping Emerging Economics.” His name is Professor Eduardo Gomez, Director of the Institute of Health Policy and Politics, at Lehigh University.

E200: Learning which food waste reduction strategies people would actually do
The average American family of four loses roughly $1,500 annually, not eating the foods they purchased. This uneaten food, at best, ends up in a compost heap or goes to household pets, or worst, this wasted food ends up in the trash, a total loss. Of course, no one wants to waste food, but there is often a disconnect between what people know they should do, as opposed to what they would do. This podcast is part of a series on food waste. My colleagues, Agricultural Economist, Brenna Ellison of Purdue University, and Penn State’s Applied Economist, Linlin Fan, and I, asked people to tell us what food waste prevention measures they would support. And we asked which strategies they thought would work. The study was published recently in the “Journal of Cleaner Production.”

E199: How USAID is working to reduce wasted food in developing countries
Today we’re looking at food waste and loss on an international scale. Did you know that over 1/3 of the world’s food is lost or wasted? In low- and middle-income countries, over 40% of food loss occurs before a crop even makes it to the market. This food loss undermines efforts to end hunger and malnutrition. Wasted food contributes 8 to 10% of global greenhouse gas emissions. Addressing this challenge is critical to global food security, nutrition, and climate change mitigation.

E198: Why SNAP pandemic benefits for college students should continue
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?
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.

E195: How USDA is tackling food waste and loss
In the United States, over one third of all available food goes uneaten through loss or waste. That is a hard number to ignore when more than 10% of the US population is food insecure. What’s more, uneaten food is the single largest category of material sent to landfills. So what is the USDA doing to address food loss and waste? Our guest today is Dr. Jean Buzby, the Food Loss and Waste Liaison in the US Department of Agriculture’s Office of the Chief Economist.

E194: Foodborne illness and the struggle for food safety
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.”

E193: Challenges and opportunities: turning food waste into valuable products
According to the Environmental Protection Agency, food is the single largest category of material sent to landfills in the US, where it emits the greenhouse gas methane. It would be a win for climate if food waste could instead be transformed into commercially valuable products. Today, we’re talking with two researchers who are working out the feasibility of just that. Welcome to the Leading Voices in Food podcast. Our guests for today are sustainability and energy science researcher Thomas Trabold of the Golisano Institute for Sustainability at Rochester Institute of Technology. And second, we have food science and technology researcher Ned Spang from the University of California Davis Food Loss and Waste Collaborative.

E191: Is today’s food waste a consequence of historical public policy?
Today’s podcast is part of a series on food waste. When farmers produce more of a product than people are willing to buy, or when the demand for a product falls unexpectedly, food is wasted. What role do agricultural policies and politics play in creating and perpetuating cycles of supply challenges? Our guest today is Dr. Garrett Graddy-Lovelace of American University. Garrett is an agricultural policy expert and she studies the problem of food gluts through the lens of social sciences, international affairs, history and analysis of USDA data.
