“Forever chemicals” (PFAS) are everywhere, but how concerned should you really be?

In this episode of Nutrition for Noobs, Michelle and Kevin are joined by toxicologist Dr. Deborah Keil to break down the science behind PFAS (per- and polyfluoroalkyl substances), a group of persistent chemicals found in water, food packaging, cookware and more.

You’ll learn:

• What PFAS are and why they’re called “forever chemicals”
• How these substances enter your body (hint: it’s not just water)
• The real health risks, including immune system effects and impacts on vulnerable populations
• Why almost everyone has PFAS in their blood, and what that actually means
• Practical ways to reduce your exposure without panic
• The role of nutrition and antioxidants in protecting your body

This episode cuts through the fear and gives you clear, science-backed guidance on what matters most (and what doesn’t) when it comes to everyday chemical exposure.

Margarine might seem like an ordinary kitchen staple, but its history is anything but boring. In this episode, originating from Trina's listener question, Michelle takes Kevin down a surprising rabbit hole that includes government bans, dairy industry lobbying, smuggling across Canadian borders, and even a literal “colour war” over whether margarine could be yellow.

What seems like a simple butter substitute has a surprisingly dramatic past. Margarine has sparked political fights, government bans, and even a black market. And just when it was celebrated as the healthier choice, science uncovered a twist that changed how we think about it entirely.

So is margarine actually healthier than butter? Michelle breaks down the latest nutrition research, explains how modern margarines are made, and shares practical tips for choosing healthier spreads. As always, the real takeaway goes beyond a single ingredient: it’s about the overall quality of your diet.

If you thought margarine was boring, think again.

In this powerful episode of Nutrition for Noobs, Michelle and Kevin sit down with radiation oncologist Dr. Zahra Kassam to unpack one of the most important, and personal, topics in health: the relationship between nutrition and cancer.

Dr. Kassam is a radiation oncologist at the Stronach Regional Cancer Centre, Assistant Professor at the University of Toronto, co-founder of Plant-Based Canada, and co-author of Eating Plant-Based. With more than 30 years in medicine, she brings both clinical expertise and deep compassion to the conversation.

Together, they explore:

• What the research really says about plant-based eating and cancer prevention
• Major population studies like the Adventist Health Study and EPIC-Oxford Study
• How nutrition may influence cancer treatment outcomes, including chemotherapy and immunotherapy response
• The role of epigenetics, and why your genes are not your destiny
• Lifestyle medicine’s six pillars and their impact on chronic disease
• Why nutrition still isn’t central in most medical training
• Practical ways patients can advocate for themselves
• Simple, realistic strategies to “plant the seeds” for change

Dr. Kassam also shares insights into how planetary health, food systems, and cancer risk are deeply interconnected, including the work of the EAT-Lancet Commission and leaders like Dr. Scott Stoll.

Whether you’re looking to reduce your cancer risk, support someone undergoing treatment, or simply understand how food influences long-term health, this episode offers evidence-based guidance grounded in both science and empathy.

As Dr. Kassam reminds us: “There is no human activity that has a deeper impact on our health and our planet than what we eat. The power is on our plate.”
