When did we start to see these family-run stores like that close?

It was before the pandemic.

Our guest today is Marian Nestle, author of What to Eat Now and one of the most influential voices in food politics.

We'll be right back after a short break.

I'm Tanya Mosley, and this is Fresh Air.

I invite influential thinkers to open up about the big topics we all think about but rarely talk about.

Tune in this fall to hear Mel Robbins, Malala Yousafzai, and Brene Brown talk about everything from grief and God to ambition and forgiveness.

Watch or listen on the NPR app, YouTube, or wherever you get your podcasts.

On NPR's Wildcard podcast, Padma Lakshmi says she feels better at 55 than 25.

This is Fresh Air.

I'm Tanya Mosley, and we're talking with Marian Nestle, whose new book, What to Eat Now, explores how our food system has changed from the rise of ultra-processed foods to the shifting politics of what's on our plates.

Okay, Marion, you identify three nutrition concepts that have emerged since your first run of What to Eat in 2006.

And those three things are the food systems have changed, ultra-processed foods, and triple-duty diets.

And I want to slow down and talk about all three.

But I want to first have you give us a brief understanding of each.

So...

In 2006, you wrote about processed foods.

A few years later, we were introduced to ultra-processed foods.

Give us some examples of ultra-processed foods.

Just remind us of what's the difference.
