2026/03/26

In 1881, African American educator and political leader Booker T. Washington founded Tuskegee Institute in Tuskegee, Alabama. The school's mission was to provide practical education and vocational training in fields such as agriculture and mechanics to African Americans in the post-Reconstruction South. Tuskegee ultimately became a world-renowned agricultural and industrial school for African Americans – and actually for all people. Today, we're speaking with Duke University's Jarvis McInnis about

2026/03/19

Over the last several years, I have been thinking about food waste and food loss a lot. It's been a topic that we've seen in many spaces in the US and around the world. And it's interesting to compare how the US handles food waste with other countries. To that end, we will learn more about how Belgium addresses food waste in a conversation with an anthropologist and journalist, Dr. Kelly Alexander from the University of North Carolina at Chapel Hill. Her book, Truffles and Trash: Recirculating Food

It seems like the frequency of weather-related disasters is increasing. Across the US we're seeing wildfires, tropical storms and hurricanes, extreme heat, extreme cold with snow or ice. And torrential rain leading to a loss of property, life, and livelihoods. What's more, similar extreme events are happening across the globe. These disasters all can have an impact on our food supply and the ability of people to access food. Today, we're speaking with environmental sustainability management expert,

Do you ever wonder whether your grocery store cares about whether you have a healthy diet? Every time we shop or read advertisement flyers, food retailers influence our diets through product offerings, pricings, promotions, and of course store design. Think of the candy at the checkout counters. When I walk into my Costco, over on the right there's this wall of all these things they would like me to buy and I'm sure it's all done very intentionally. And so, if we're so influenced by these things, is

An avalanche of information besets us on what to eat. It comes from the news, from influencers of every ilk, from scientists, from government, and of course from the food companies. Super foods? Ultra-processed foods? How does one find a source of trust and make intelligent choices for both us as individuals and for the society as a whole. A new book helps in this quest, a book entitled Food Intelligence: the Science of How Food Both Nourishes and Harms Us. It is written by two highly credible and

Lots of talk these days about ultra-processed foods (UPFs). Along with confusion about what in the heck they are or what they're not, how bad they are for us, and what ought to be done about them. A landmark in the discussion of ultra-processed foods has been the publication of a book entitled Ultra-processed People, Why We Can't Stop Eating Food That Isn't Food. The author of that book, Dr. Chris van Tulleken, joins us today. Dr. van Tulleken is a physician and is professor of Infection and Global

The Food and Drug Administration or FDA regulates roughly 78% of the US food supply. This includes packaged products, food additives, infant formula, ultra-processed foods, and lots more. However, an analysis by the Environmental Working Group found that 99% of new food ingredients enter our food supply through a legal loophole that skirts FDA oversight and seems, to me at least, to be incredibly risky. Today we're speaking with two authors of a recent legal and policy analysis published in the

Every day, with few exceptions, I eat a handful of nuts. Usually a combination of almonds, walnuts, pecans, cashews, and pistachios. And they taste good for sure. But I'm responding mainly to research showing that consumption of nuts is related to less chronic disease. In particular, eating nuts lowers levels of inflammation related to heart disease and diabetes, and may improve cholesterol levels among other benefits. So, I saw it as welcome news that someone has just published a book about nuts,
