Is Processed Meat Really Bad for You? with Dr. Frederic Leroy
Most of us hear the words “processed meat” and immediately think unhealthy.
But is a traditionally fermented salami really the same thing as an ultra-processed meat snack packed with sugar, fillers, and additives?
In this episode of the ReThink Health Podcast, I sit down with Dr. Frederic Leroy, a professor and food scientist who has spent decades studying animal-source foods, fermentation, food processing, and human nutrition.
Dr. Leroy explains why lumping every processed meat into one category misses some important details. (Humans have been drying, curing, smoking, and fermenting meat for thousands of years, and traditional products can look very different from modern ultra-processed versions!)
It’s a refreshingly nuanced conversation that moves beyond “processed meat = bad” and asks a much more useful question: What kind of processing are we actually talking about?
You’ll learn:
- The difference between traditionally processed and ultra-processed meat products
- What the WHO’s processed-meat classification actually tells us about hazard vs. risk
- Why much of the processed-meat research relies on observational data, and why that matters
- How traditional fermentation, curing, drying, and smoking preserve meat
- How to spot a higher-quality processed meat by reading the ingredient list
- What nitrates and nitrites actually do in cured meats (and why celery-derived nitrate is still the same molecule)
- What we know (and don’t know) about probiotics, postbiotics, and bioactive peptides in fermented meats
- Dr. Leroy’s simple framework for building a nourishing diet without following rigid food rules
If you’ve been avoiding ham, salami, jerky, or meat sticks because you’ve heard that all processed meat is unhealthy, this episode will help you understand the important differences that rarely make it into nutrition headlines.

About Dr. Frederic Leroy
Dr. Frederic Leroy is a professor and food scientist with a PhD in Applied Biological Sciences whose work focuses on animal-source foods, food processing, fermentation, human nutrition, and food systems. His training began in food science and nutrition, including research into food and nutrient security in Africa, before he completed doctoral work in food processing and engineering.
His early research into meat fermentation examined the microbiology, safety, and quality of fermented foods such as salami. Today, his work takes a broader look at the role of animal-source foods in human nutrition, health, sustainability, food culture, and society.
