On this episode of On Nutrition, we talk with gastroenterologist Dr. Purna Kashyap about why we need to keep our gut microbes healthy, the importance of fiber, and the pros and cons of pre- and probiotics.

Bright orange cheese puffs. Daffodil-yellow snack cakes. Lime green soda. These are clearly ultra-processed foods. But, what about your frozen veggie burger, your protein cookie, or even that whole wheat bread you buy at the grocery store? You might not think you eat ultra-processed foods, but unless you’re living 100% farm-to-table, you probably do. So, are ultra-processed foods as scary as they sound? Should we stop eating them altogether… and is that even possible?

On this episode of Mayo Clinic on Nutrition, we talk with Dr. Stephen Kopecky about the ultra-confusing world of ultra-processed foods.

If you were around during the 90's, you probably remember the low-fat and fat-free craze: skim milk, low-fat snacks... and god forbid you ate a plate of eggs. Today, we know a lot more about fat, and that certain types of fat are actually an important part of a healthy diet. So, how do you keep track of which fats you're supposed to eat, and which you're supposed to avoid?

On this episode of On Nutrition, we talk with Dr. Kyla Lara-Breitenger to untangle our notions of "good" and "bad" fats, demystify cholesterol, and embrace the tastiness—and healthiness—that fat can bring to our food.
