Description

What does that ingredient on your label actually do in your body, and why is TikTok so mad about it? On Ingredients, we pick one nutrient or ingredient at a time and unpack it from every angle: biochemistry, physiology, public health, and the social media discourse that shapes how we feel about food. Hosted by Susana, a registered dietitian, and MJ, a public health person, this podcast is where evidence meets everyday eating, and nutrition trends get a much-needed reality check.Find Susana here:TikTok and Instagram: susana.ritchey.rd Bluesky Social: susanaritcheyrd.bsky.social An Everything is Public Health production.

Fat

2026/07/22

The Dietary Guidelines to limit saturated fat to less than 10% of our calories didn’t change. The political and social beliefs surrounding animal and plant fats did. In this episode, MJ and Susana talk about the divide between the scientific community and pop nutrition influencers—including some in positions of power, and how that divisions can make using canola oil or eating an avocado a bit confusing and sometimes polarizing.

Sodium

2026/01/28

Those fancy salts are fun to cook with, but for health? Not so much. Also, are all those hydration packs doing anything?

Calories

2026/01/14

Calories are one of the most prominently placed items on the nutrition facts label, but how much weight should we place on them? Susana and MJ unpack what a calorie actually measures, how metabolism really works, and why “calories in, calories out” sparks so many online debates. We separate what’s physiologically true from what gets lost in viral nutrition discourse.
