Podcast Summary: Exploring the Science of Wine and Health with Dr. Laura Catena

Becker’s Healthcare Podcast — March 12, 2026
Host: Scott Becker
Guest: Dr. Laura Catena (physician, emergency medicine specialist, and leader in a multi-generational Argentine wine family)

Episode Overview

In this engaging episode, Scott Becker sits down with Dr. Laura Catena to explore the nuanced and often controversial science at the intersection of wine and health. Drawing from her unique background as both a physician and a steward of her family’s historic winery, Dr. Catena provides a thoughtful, evidence-based discussion of wine’s potential health impacts — both benefits and risks — and highlights exciting new research that may finally shed clearer light on this complex issue.

Key Discussion Points & Insights

1. Dr. Catena’s Unique Perspective and Background

[01:05 – 02:53]

• Dr. Catena introduces herself as an Argentine physician whose family has produced wine for generations.
• She shares her journey:
  • Emigrated to the U.S. during Argentina’s challenging 1980s era.
  • Studied biology at Harvard, then medicine at Stanford, becoming an emergency physician.
  • Maintained dual roles: practicing medicine and helping lead her family winery.
• Her interest in wine and health stems both from her heritage and a sense of responsibility to present accurate, science-based information in the face of shifting media and scientific narratives.
• Advocates for nuance: “As a physician, I need to make sure to tell people the correct science. …I think it’s really important to know what we know, what we don’t know, and to not take sides.” (C, 01:05–02:53)

2. What Does the Science Actually Say? A Balanced Perspective

[02:53 – 07:48]

• Reviews the evolution of thinking: moderate wine consumption long believed part of a healthy, Mediterranean lifestyle — but newer press and guidelines often warn against alcohol entirely.
• Key points from research:
  • Most studies examine alcohol generally, not wine specifically.
  • Consistent findings over 30 years: Moderate drinkers (up to one glass daily for women, two for men) live longer and have fewer heart attacks compared to never drinkers (National Academy study, 2025).
  • Increased Risks: Small but present increased breast cancer risk; higher esophageal/oropharyngeal cancer rates mainly in heavier drinkers who also smoke.
  • Some newer genetic (Mendelian randomization) studies muddy the waters — sometimes showing no cardiac benefit or cancer risk at moderate levels.
  • Observational research supports associated, not necessarily causal, reductions in stroke, sudden death, heart attacks, and diabetes among moderate drinkers.
• Crucial physician caution:
  • “If you tell people drinking wine or beer or whatever in moderation might help you, people tend to drink more and binge drink. …So as physicians, we have to be really careful with patients…” (C, 06:53–07:48)
  • No guideline recommends starting to drink for health reasons; the risk of alcohol use disorder is unpredictable.

3. Notable Nuances and Memorable Quotes

• On guidelines vs. real life:
  • “For me, I’m of Italian descent. That’s part of my culture. I really like my little glass of wine that I don’t have every day because I like to not drink every day. And, you know, I don’t think right now the data is telling us you should stop that habit if you’re drinking in moderation.” (C, 07:30–07:48)
• On public behavior:
  • “If the doctor says I could eat a certain thing… then I overdo it… I splurge.” (B, 07:48–08:17)
• Welcoming disagreement and conversation: “I always welcome people saying they disagree, which happens a lot in this field, 100%.” (C, 02:08)

4. A Landmark Study: The Spanish RCT

[08:46 – 10:33]

• Dr. Catena shares excitement for a major ongoing randomized controlled trial (RCT) in Spain — the first of its kind focused on wine:
  • University of Navarra, led by Dr. Miguel Anche Martinez Gonzalez.
  • Enrolling Mediterranean-diet adherents, randomizing them to continue or stop wine consumption.
  • Large cohort: aiming for 10,000; already at 7,500 participants.
  • Objective measurements (urine and hair) ensure accurate self-reporting — a major innovation.
  • May clarify whether moderate wine drinking has true cardiovascular benefits.
  • Results expected by 2029.
• “This is the golden standard study… because it will at least tell us: is there a potential cardiovascular benefit?” (C, 09:40–10:02)

5. Final Advice to Physicians & Reflections

[10:33 – 12:16]

• Dr. Catena openly discloses her conflict of interest as a winery owner, urging listeners to review research by others (links on https://indefenseofwine.com).
• Her core advice to physicians:
  • Cherish time with patients; hopes AI will reduce paperwork burdens so doctors can focus on direct care.
  • “Patient care is what I always love to do. And I think it’s such a noble profession, so rewarding. But making wine is kind of fun, too.” (C, 11:02–11:13)
  • Encourages diverse experiences and embracing change in one’s career.

Notable Quotes

• "As a physician, I need to make sure to tell people the correct science. …I think it’s really important to know what we know, what we don’t know, and to not take sides." — Dr. Laura Catena [01:55]
• “There’s some data that shows off the lifespan. There’s definitely data with cancer. So if you really like drinking and it’s part of your social life…well, that’s wonderful.” — Dr. Laura Catena [07:15]
• "Most guidelines, all guidelines say that you should not tell somebody to start drinking for health because you don’t know who’s going to develop an alcohol use disorder." — Dr. Laura Catena [07:42]
• “This is the golden standard study… because it will at least tell us: is there a potential cardiovascular benefit?” — Dr. Laura Catena [09:48]
• “Patient care is what I always love to do. And I think it’s such a noble profession, so rewarding. But making wine is kind of fun, too.” — Dr. Laura Catena [11:02]

Summary Takeaways

• The relationship between wine and health is nuanced. Decades of evidence point to potential associated benefits from moderate drinking, but risks (notably cancer) do exist, and causality is not established.
• Physicians should communicate clearly: moderation is key, and no one should start drinking for health reasons.
• A new Spanish RCT may soon provide the best available evidence on wine’s true health impacts.
• Dr. Catena advocates for authenticity, ongoing learning, and cherishing patient interactions—while also celebrating the joy of a well-made glass of wine.
