Podcast: The Dr. Hyman Show
Host: Dr. Mark Hyman
Guest: Sam Kass (Former White House Chef, Food Policy Leader, Author) Episode: Former White House Chef Sam Kass: How to Overcome the Coming Food Crisis
Date: October 29, 2025

Episode Overview

This episode features a thought-provoking conversation between Dr. Mark Hyman and Sam Kass, former White House chef and senior policy advisor on nutrition, now a leading advocate for food systems reform. The discussion centers on the urgent and multifaceted food crisis threatening the health of people, economies, and the planet, drawing direct lines between industrial agriculture, chronic disease, climate change, and national security. Kass expounds on key insights from his new book, "The Last Supper: How to Overcome the Coming Food Crisis," laying out what’s at stake, why the current system is failing, and what cultural, policy, and industry shifts are needed for meaningful change.

Key Discussion Points & Insights

1. The Imminent Food Crisis

Not a Future Problem—It’s Now
- Sam calls out the misconception that climate-related food system changes are long-term concerns:
  
  "It's not about our kids and grandkids. This is happening right now." – Sam Kass [00:02, 07:45]
- Foods Americans take for granted, like coffee, wine, chocolate, shellfish, stone fruits, and nuts, are already being affected by climate volatility.
Personal and Cultural Impact
- The loss of these foods isn’t just about health or economics—it’s about culture and "our way of life."

2. How Industrial Agriculture Drives Crisis

Ecological and Health Externalities
- Dr. Hyman details the interconnected damage caused by commodity-based, monoculture agriculture:
  - Loss of soil and biodiversity
  - Pollinator die-off
  - Waterway pollution via fertilizer runoff
  - Aquifer depletion (e.g., Ogallala)
  - Chronic disease epidemic driven by ultra-processed foods
  - Direct costs to the healthcare system (~$2 trillion/year)
- Refers to these as "externalities," but argues they are true, direct effects [02:08-05:19].
Agriculture’s Outsized Role in Climate Change
- Food systems contribute around 34% of anthropogenic greenhouse gas emissions [00:26, 08:34].
- Soil carbon loss, deforestation, methane from livestock, and the dominance of just a few crop and animal species make the food system a linchpin for climate action.

3. Systemic Vulnerabilities & National Security

Lack of Resilience / Over-Reliance on Monocultures
- Over 60-70% of the world’s calories come from just 12 plants and 5 animals.
- Wheat, rice, corn, and soy dominate, amplifying food insecurity as climate impacts these crops [12:25].
- "If you lose one plant in a monocrop, it's a disaster… If you lose one in a rainforest system—no big deal." – Dr. Mark Hyman [33:30]
Water Scarcity and Geopolitical Instability
- Agriculture uses over 70% of fresh water globally. Expected to outstrip supply by 2030 [11:04].
- Sam draws links to potential national security issues if staple crop yields collapse.

4. The Promise (and Challenges) of Regenerative Agriculture

Definition & Principles
- Not one-size-fits-all: focus on outcomes—building soil health, increasing biodiversity, sequestering carbon, and improving water retention [23:50-25:57].
- Integrates animals back into farming systems in ways that mimic natural ecosystems.
Potential for Carbon Sequestration and Resilience
- Soil is the largest terrestrial carbon sink; regenerative practices are the only pathway that could both feed people and pull carbon from the atmosphere fast enough.
- "It is the only system on the planet that has the capacity not just to reduce their negative impact… but also sequester enough carbon." – Sam Kass [14:11]
Barriers: Transition Costs & Policy Roadblocks
- Farmers face high risk, low margins, and policies that reward monoculture.
- Transformation requires new incentives, technical support, and transitional funding [16:00–19:17].

5. Incentivizing Change: Policy, Finance, and Markets

Who Pays for Regeneration?
- Need to "de-risk" transitions for farmers: crop insurance, technical support, pay for ecosystem services, and create new markets [26:08].
- Sam proposes robust carbon (and potentially water and biodiversity) markets where big emitters (especially oil/gas, not just food companies) pay farmers for carbon sequestration and ecosystem services [28:42–33:30].
- “Big emitters should be paying our growers to solve these problems.” – Sam Kass [28:42]
The True Cost of Food
- Rocky path to pricing food for externalities without pricing out consumers.
- Policy must balance ecosystem costs with food affordability [28:42].

6. The Role of Meat and "It’s Not the Cow, It’s the How"

Factory Farming vs. Integrated Systems
- CAFOs (factory farms) are inherently damaging; regenerative animal agriculture can build soil and restore ecosystems [33:30, 36:57].
- Debate exists about whether grass-fed is truly better in terms of direct emissions, but clear environmental benefits to integrated, pasture-based systems.
Efficiency vs. Nutrient Density
- Sam advocates reducing consumption of resource-intensive large animals (beef), suggesting a shift toward smaller animals (chicken) and higher prices for "quality over quantity" meat.
Memorable Exchange
- “First of all… I am definitely not a vegan. I love a good steak.” – Sam Kass [38:05]
- “It’s not the cow, it’s the how…” – Dr. Mark Hyman [36:57]

7. Driving Change: Culture, Policy, Industry

Cultural Shifts Drive Policy
- Policy is often constrained; major change comes from grassroots cultural shifts and consumer demand.
- “If we don’t do the hard, messy, slow, difficult work of shifting our culture, policy is always going to let us down.” – Sam Kass [43:26]
Personal Influence & Leadership
- Even small acts—changing family food culture, advocating at workplaces, and community organizing—ripple outwards.
- Sam’s anecdote about a teammate’s opinion leading him to quit soda [43:14].
Citizen Action Matters
- Legislators respond to constituents. Dr. Hyman notes, "what people say matters" and can outweigh even industry influence [48:49].

8. Ultra-Processed Foods and Regulatory Challenges

Defining "Food" and Regulating Ultra-Processed Inputs
- Discussion on David Kessler’s FDA petition to re-evaluate the GRAS (Generally Recognized as Safe) status of modern processed food ingredients [50:51–53:17].
- Kass: Legal and regulatory barriers will likely stall this approach—hard to prove harm of any one product, though the aggregate is damaging.
Policy Levers
- Front-of-package warning labels (effective in South America for reformulation and consumer behavior) [61:01].
- Financial markets exert powerful (often perverse) pressure—quarterly reporting and shareholder value often trump efforts to reformulate for health/environment [64:57–66:15].

9. Political Realities and Bipartisan Action

Emergence of Bipartisan Movement
- The "Make America Healthy Again" (MAHA) movement is bringing food reform back onto the national stage.
- Surreal shift: Once a "Democrat" issue, now seeing Republican leadership and bipartisan traction.
- Both hosts express cautious optimism but concern that the current focus (seed oils, food dyes) can become a "distraction" from the main drivers—sugar and ultra-processed foods [69:52–74:22].
Policy Recommendations ("If You Were Food Czar…")
- Revise GRAS and food regulation for ultra-processed ingredients
- Expand and restructure SNAP (food stamps) and WIC to support nutritious food purchases, not just cut benefits [80:34–81:19]
- Raise school food standards
- Address agricultural subsidy reform to support regenerative transitions
- Consider sugar taxes (politically challenging)

Notable Quotes & Memorable Moments

On Climate and Food Culture:
- “What's really at stake is our way of life, our ability to pass down to the next generation the delicious lives we have...” – Sam Kass [00:02]
On the Need for Urgency:
- “This isn't about our children or our grandchildren. This is happening right now.” – Sam Kass [07:45]
On Regenerative Agriculture:
- “We're investing in not just what we extract, but what we're building in the soil.” – Sam Kass [23:50]
- “It’s mimicking nature and complex ecosystems, which are far more resilient.” – Dr. Mark Hyman [33:30]
On Power of Citizens:
- “If our constituents are calling our office… we're listening. It can override what's happening from industry.” – Dr. Mark Hyman [48:49]
On Scope of the Solution:
- “This is a solvable problem. We have the science, we know what to do, we know how to do it…” – Dr. Mark Hyman [86:25]

Final Thought

As Dr. Hyman wraps up:

“Margaret Mead said, ‘Never doubt that a small group of committed people can change the world. In fact, it’s the only thing that ever has.’ … Don’t feel like you can’t do anything. You can.” [88:12–89:26]
