In Proof, the new podcast from America's Test Kitchen, we aim to solve food mysteries one story at a time. Every episode goes beyond recipes and cooking to investigate the foods we love (such as deep-fried oreos and tiki drinks) and don't love (like once-in-vogue celery and the meteoric rise of the grain bowl); ask the big questions (where do food cravings come from?); and uncover the hidden backstories that feed your food-obsessed brain.


 

In the second episode of Proof, we enter the world of cravings. We all have them, whether it’s an overwhelming need for something sweet or a bite of one of our grandmother’s specialties. But where do they come from?

Proof, Episode 2 Cravings

We all get them. Where do they come from?

Five Things You’ll Learn

1. What Causes Cravings: And the answer isn’t so cut and dry. There are physiological, biological, and psychological components of cravings, and there are also gender differences and memory causes linked to them.

2. The Difference Between Hunger and Cravings: We all know that the former is when the belly lets you know that it needs to be filled, and the latter is a soul-crushing demand to eat this now. You’ll learn the more scientific differences if you listen to the episode.

3. The Most Commonly Craved Food in the United States: Almost every woman in the U.S. and about two-thirds of men say they’ve craved this ingredient. But it’s not as popular a craving outside of America: Only about 5 percent of women in Egypt and 28 percent of women in Spain report this craving.

4. One of the Most Commonly Craved Foods in the NBA: It’s the humble peanut butter and jelly sandwich. They’re common in locker rooms around the league, and according to ESPN reporter Baxter Holmes, in the past, the Milwaukee Bucks would provide their players with an elaborate buffet of different nut butters, jams, jellies, marmalades, Nutella, and breads.

5. The Chemical Composition of Cravings: Beyond certain foods’ flavor, chemicals like dopamine, caffeine, and cannabinoids contribute to our cravings for them.

“I count how much coffee I’ve had not in cups but in pots. I have a real REAL problem. There will even be a part of the day where I’m actually afraid that I can’t get to coffee.

There’s a fear that sets in that I’m gonna run out.” —Bridget Lancaster, on her coffee cravings
