Ultra-processed foods are everywhere, but most people don’t fully know what the term means. In Part 1 of this two-part series, we start from the beginning: how the modern ultra-processed food concept emerged, why it was created, and how the NOVA classification system defines ultra-processed foods today.

In this episode

• The history behind processed foods
• What “ultra-processed” means
• The modern origin of the term and why researchers introduced it
• NOVA 101: the four groups and what makes a food ultra-processed

Coriander is either fresh, citrusy, and full of bursts of happiness or it tastes like soap and ruins your entire meal. There seems to be no in-between.

In this episode, we unpack what coriander is, why it has different names, where it comes from, how it shows up in so many cuisines and what the peer-reviewed science says about the soap tasting situation. We also break down coriander leaves vs coriander seeds, compare it to other herbs and get practical with recipes, storage, and substitutions.

In this episode

• Coriander, cilantro, dhania, coriandre, and كزبرة
• Where coriander likely originated
• The genetics: the 2012 genome-wide association study and OR6A2
• The chemistry behind the soap issue
• Leaves vs seeds
• Coriander compared to other herbs
• Practical and common uses
• How to cook around cilantro if it tastes like soap

One of my listeners, Emily, shared a question that sent me down a nerdy rabbit hole. She grew up in Canada eating potatoes as a staple and can eat a lot of them with no problem but rice makes her full really fast. Her Indonesian friends are the opposite: they can eat a lot of rice, but potatoes shut them down fast.

In this episode, we explore whether there’s any scientific reason behind this so come join me and find out what the data really says!

In this episode:

• Where potatoes and rice originated, how they spread globally and how many varieties exist
• How we define fullness
• Expected satiety
• Gastric emptying explained and what it implies for rice vs potatoes
• Why rice and potatoes aren’t single foods
• The genetics angle
• The answer to the question
