Episode: The Real Reason You Should Drink Apple Cider Vinegar Daily! - Dr. G's Quick Health Tip | EP 366.B
Date: August 28, 2025
Host: Dr. Steven Gundry

In this solo episode, Dr. Gundry delivers a deep dive into the science and health benefits behind adding apple cider vinegar—especially with the “mother”—to your daily routine. Straddling the latest microbiome research and practical lifestyle advice, he ties together how vinegar can impact gut health, metabolic well-being, skin, and satiety, while also offering comparisons to other vinegars and reminders about choosing the healthiest products.

Key Discussion Points and Insights

What Is Apple Cider Vinegar and How Does It Work?

• Fermentation Basics
  • Vinegar forms from bacterial fermentation (not yeast), with acetic acid being the key component.
  • Acetic acid is a short-chain fatty acid (SCFA), important for mitochondrial and brain health.
  • [01:00]

"Bacterial fermentation in general is how vinegars are made. Now, one of the most important vinegar components is acetic acid."
—Dr. Gundry [01:03]

SCFAs and Gut Health: The Butyrate Connection

• Importance of Butyrate
  • Butyrate (butyric acid) is considered “the holy grail” of SCFAs for gut and overall health.
  • Problem: Due to antibiotics in people and food, we often lack butyrate-producing bacteria.
• Role of Soluble Fiber
  • Traditionally, butyrate must be made from soluble fiber.
  • Recent studies (Sonnenberg at Stanford): Fiber alone didn’t improve microbiome diversity or lower inflammation unless fermented foods (rich in SCFAs like acetic acid) were added.
• Key Finding:
  • The combination (“one-two punch”) of fiber plus SCFAs/fermented foods leads to more diverse, healthier gut microbiomes and reduced inflammation.
  • [02:00–05:00]

“It was only after the addition of these precursing short chain fatty acids like acetic acid, like propionic acid, that then their gut microbiome diversity increased and their inflammation markers decreased. So it’s a one, two punch.”
—Dr. Gundry [03:18]

Appetite, Digestion & Satiety

• Daily ACV and Satiety:
  • Acetic acid can modulate hunger hormones (GLP-1 agonists), promoting fullness.
  • Vinegar slows gastric emptying, which moderates the rate of food absorption—a mechanism shared by some weight loss drugs.
• Timing and Traditions:
  • Taking vinegar with meals mimics traditional culinary practices (e.g., salads as the first or last course) that may harness this effect.
  • [06:00–07:30]

“That extra shot of acid in the form of a vinegar delays gastric emptying and slows the absorption of food.”
—Dr. Gundry [06:59]

Skin Health: The Gut-Skin Connection

• Visible Benefits:
  • Healthy gut lining (“skin turned inside out”) is often reflected in healthy, glowing skin.
  • Improving gut health via ACV can enhance skin appearance.
  • [08:00]

“If you want healthy glowing skin, apple cider vinegar is a great way to improve your skin health by improving your gut wall health.”
—Dr. Gundry [08:45]

ACV vs. Balsamic Vinegar & Polyphenols

• Balsamic as a Polyphenol Powerhouse:
  • Contains the highest amounts of bioavailable resveratrol, more so than red wine or supplements.
  • Also helps uncouple mitochondria, which is linked to longevity.
• Apple Cider Vinegar Polyphenols:
  • Contains valuable polyphenols, particularly from apple peels, but less than balsamic and olive oil.
  • Emphasis on choosing organic due to pesticides (“Dirty Dozen” alert).
  • [09:00–11:00]

“Balsamic vinegar has the highest amount of bioavailable resveratrol... more so than even taking a capsule of resveratrol.”
—Dr. Gundry [09:21]

The “Mother” in ACV

• What Is the Mother?
  • The cloudy sediment: remnants of beneficial bacteria (“dead bodies”).
  • These postbiotics transmit signals to boost good gut bacteria.
  • Choose unfiltered, organic varieties for this reason.
  • [11:00–12:30]

“The mother is kind of all the leftover dead bodies of these bacteria that sink to the bottom... These dead bacteria carry information. They are postbiotics that carry very important information to tell your other gut buddies... to party like it's 1999.”
—Dr. Gundry [11:18]

Usage, Safety, and Practical Tips

• Potential for Over-Use:
  • ACV is acidic and can irritate gums or teeth—dilute it or use as dressing to reduce risk.
• How to Take It:
  • Mix with olive oil for a double benefit: gains from both fatty acids and polyphenols.
• Brand Recommendation:
  • Praises Bragg’s “mother” vinegar (and reiterates the importance of organic choices).
• Final Tip:
  • “Mix your apple cider vinegar with olive oil and take a shot of that.”
  • [13:00–14:00]

Notable Quotes & Memorable Moments

• On the one-two punch for gut health:

  “It was only after the addition of these precursing short chain fatty acids like acetic acid, like propionic acid, that then their gut microbiome diversity increased and, and their inflammation markers decreased. So it’s a one, two punch.”
  —Dr. Gundry [03:18]

• On satiety and digestion efficiency:

  “That extra shot of acid in the form of a vinegar delays gastric emptying and slows the absorption of food… these weight loss drugs, the GLP1 agonists like Ozempic or Wegovy, work in part by delaying gastric emptying. So why not just have a shot of balsamic vinegar with your meal?”
  —Dr. Gundry [06:59]

• On the importance of choosing organic:

  “The Environmental Working Group just put apples onto the Dirty Dozen list of worst contaminated fruits you can eat. So, please, if you’re going to get apple cider vinegar, make sure you get the organic variety.”
  —Dr. Gundry [11:49]

• On mixing ACV and olive oil:

  “If you really want to use apple cider vinegar as your shot of getting polyphenols, do me a favor. Mix your apple cider vinegar with olive oil and take a shot of that.”
  —Dr. Gundry [13:59]
