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." H ..read more

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 wha ..read more

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. Interview Summary   Norbert: Ahmed, let's begin with a question for you. Can you tell our listeners why USAID ..read more

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.  Interview Summary ..read more
