Dr. Kellogg Cereal, Surgery, and Strange Ideas

Published on: 26th June, 2025

🥣 The Curious Case of Dr. Kellogg: Surgeon, Cereal, and a Whole Lot of Enemas

When you think of Kellogg, you probably picture cereal—maybe a sweet bowl of Frosted Flakes or Corn Flakes. But the real story behind Kellogg is far weirder than breakfast. It starts with a doctor. A good one. A very strange one.

Meet Dr. John Harvey Kellogg

Dr. John Harvey Kellogg wasn’t just any doctor. He was a skilled surgeon, and even Dr. Charles Mayo—the founder of the Mayo Clinic—called him one of the best abdominal surgeons he had ever seen.

But Kellogg didn’t become famous for his surgery skills. Instead, he became known for his obsession with health, diet, and—believe it or not—poop.

The Sanitarium and the Celebrity Patients

Kellogg ran the famous Battle Creek Sanitarium in Michigan. This health resort attracted celebrities like Thomas Edison, Henry Ford, and even Amelia Earhart. People came there to “cleanse” their bodies with special diets, exercise, sunlight, and—yes—daily enemas.

He believed almost every illness started in the colon. His solution? Flush it out. Constantly. Sometimes, with yogurt. Sometimes, both ends. I wish I were kidding.

Kellogg’s War on Pleasure

Dr. Kellogg didn’t just worry about digestion. He also believed that pleasure—especially sexual pleasure—was dangerous. In fact, he thought masturbation caused everything from bad digestion to insanity.

To fight back, he recommended boring, bland food. No spices. No excitement. Just plain meals that wouldn’t "stir the passions."

That’s how Corn Flakes were born. Kellogg invented them as a food so bland, they might help people forget about sex altogether.

Cereal Becomes a Business

Now, here’s where things get interesting. Kellogg’s brother, W.K. Kellogg, thought those flakes had potential—but they needed flavor. So he added sugar and started selling them to the public.

Dr. Kellogg was furious. He believed sugar was poison. The two brothers fought in court. W.K. won. And that’s why your breakfast cereal today is sweet and not designed to stop anyone’s libido.

What Science Says Today

Let’s be clear: Dr. Kellogg got a lot of things wrong.

  • You do not need daily enemas. Your colon cleans itself.
  • Yogurt goes better in a bowl than through a tube.
  • Masturbation doesn’t cause disease. It’s a normal, healthy part of being human.
  • And your desire to eat or love has nothing to do with how spicy your dinner was.

While Kellogg’s focus on exercise and plant-based diets was ahead of his time, his fear of pleasure and obsession with “cleansing” caused more harm than good.

The Strange Legacy

Dr. Howard Markel, in his excellent book The Kelloggs: The Battling Brothers of Battle Creek, dives deep into their story. He shows how Dr. Kellogg's strict health beliefs turned into fads—and how his brother’s sweet-toothed success made cereal a worldwide business. Markel, Howard. The Kelloggs: The Battling Brothers of Battle Creek. Pantheon Books, 2017

Kellogg's ideas were extreme, but they still echo today. Whenever someone tells you to "detox," do a cleanse, or eat bland food to fix your hormones—they might not realize they’re following a 19th-century surgeon who really hated fun.

Dr. Markel was a medical school classmate of mine, and his book is excellent.

Final Thought

Dr. John Harvey Kellogg was a brilliant surgeon. But being smart doesn’t mean being right. And it definitely doesn’t mean you should give yourself a yogurt enema.

So next time you reach for a box of cereal, remember: your breakfast has a backstory. And it’s weirder than you think.

Speaker:

>> Dr. Terry Simpson: Today we're diving into the strange legacy of a man

Speaker:

who was by all accounts, including Charlie

Speaker:

Mayo himself, you know of the Mayo Clinic, A

Speaker:

damn fine surgeon. He was a pioneer of

Speaker:

aseptic technique, a skilled operator, but

Speaker:

also a man who thought yogurt enemas were a,

Speaker:

ah, cure to all your problems. Ladies and

Speaker:

gentlemen, meet John Harvey Kellogg.

Speaker:

I am your Chief Medical Explanationist, Dr. Terry Simpson. And

Speaker:

this is Fork you, Fork University,

Speaker:

where we bust a few myths, make sense of the

Speaker:

madness and teach you a little bit about food

Speaker:

as medicine.

Speaker:

Dr. Kellogg ran the Battle Creek

Speaker:

Sanitarium in Michigan. This wasn't just

Speaker:

a hospital, it was a health mecca for the rich

Speaker:

and famous. Presidents came here, Thomas

Speaker:

Edison came here, Amelia Earhart and

Speaker:

Henry Ford. They all came for Dr.

Speaker:

Kellogg's healing regimens. And

Speaker:

all of them suffered from overweight like President

Speaker:

Taft or dyspepsia. And to

Speaker:

be fair, Dr. Kellogg was ahead of his time in some

Speaker:

areas. He championed exercise, clean air,

Speaker:

bathing. And he was one of the early vegetarians,

Speaker:

when most doctors were still prescribing arsenic and

Speaker:

leeches. And again by surgical

Speaker:

reputation, he was top tier. He'd

Speaker:

even trained some at the prestigious

Speaker:

clinic in the United Kingdom. He was a

Speaker:

classmate of Charlie Mayo. And Charlie Mayo, who was one

Speaker:

of the founders of the Mayo Clinic, noted that anytime he saw a

Speaker:

scar, he could tell it was Dr. Kellogg's work because it

Speaker:

was beautiful, small and complete.

Speaker:

In fact, Charlie Mayo said that Kellogg was the best

Speaker:

abdominal surgeon he had ever seen.

Speaker:

But like a vintage bottle of snake oil,

Speaker:

things got weird and fast.

Speaker:

Let's talk about colons and their

Speaker:

therapy now. Dr. Kellogg was a

Speaker:

Seventh Day Adventist, which had a great

Speaker:

influence on his thinking.

Speaker:

But Dr. Kellogg also believed that 90% of

Speaker:

all illnesses began in the colon. Constipation was

Speaker:

the root of all things evil. He was the

Speaker:

original gut health guy. But instead of probiotics and

Speaker:

kombucha, he pushed daily enemas.

Speaker:

Yogurt. Enemas, yes,

Speaker:

yogurt up the back, sometimes

Speaker:

followed by oral yogurt. That's right. He was a

Speaker:

two way street kind of a doc. He believed

Speaker:

flushing the bowel would rid the body of toxins,

Speaker:

increase virility, and his favorite, prevent

Speaker:

masturbation. That's right. His

Speaker:

war wasn't just against constipation,

Speaker:

it was against pleasure.

Speaker:

Kellogg wrote extensively, painfully

Speaker:

extensively, about the dangers of self

Speaker:

pleasure. According to him,

Speaker:

masturbation caused everything from epilepsy to

Speaker:

acne to poor digestion to early death.

Speaker:

All of it one hand in the pants, your

Speaker:

Soul was halfway to hell. So he waged a,

Speaker:

uh, culinary war on libido.

Speaker:

This came from his influence in the Seventh Day Adventist,

Speaker:

whose prophet, Mary Baker

Speaker:

Eddy, believed that meats inflamed the passions.

Speaker:

He believed bland foods could calm the passions. Which is

Speaker:

how he got his original invention. Cornflakes.

Speaker:

No sugar, no flavor, just

Speaker:

bland libido. Crushing cereal.

Speaker:

Imagine creating a food so boring, it

Speaker:

was meant to extinguish lust. That

Speaker:

was his brand. If you think Ozempic

Speaker:

is an appetite suppressant, try a bowl of the

Speaker:

Kellogg's original flakes. Your hunger,

Speaker:

desire and your will to live all

Speaker:

disappear by spoonful. 3.

Speaker:

Now let's enter his brother. His brother was

Speaker:

the younger figure, the bookkeeper of

Speaker:

the Kellogg Sanitarium. But

Speaker:

his brother was also business savvy and

Speaker:

kind of hungry. And his brother, W.K.

Speaker:

kellogg, saw potential in the cornflake.

Speaker:

But he wanted to sweeten the deal. Literally. What about

Speaker:

John Harvey Kellogg? Horrified because sugar was

Speaker:

sinful and flavor encouraged moral declay.

Speaker:

Well, WK Went rogue. Added sugar,

Speaker:

built an empire, and sued his brother to keep the

Speaker:

family name on the box. He won. And the

Speaker:

rest is breakfast history. Dr.

Speaker:

Kellogg's anti pleasure cereal became the sugary

Speaker:

staple of American mornings. Precisely the

Speaker:

opposite of what he intended. Irony,

Speaker:

thy name is Kellogg. So what does science

Speaker:

say? Now? Let's start with enemas.

Speaker:

Outside of, uh, prepping for colonoscopy or the occasional

Speaker:

medical necessity, you don't need one. Your

Speaker:

colon cleans itself. That's literally what we call

Speaker:

peristalsis is for daily enemas can

Speaker:

actually harm your gut. Microbiome and

Speaker:

yogurt better when it goes through the top.

Speaker:

Preferably with berries, not with tubing.

Speaker:

As for masturbation, perfectly normal, healthy, even

Speaker:

lowers stress, improves mood, and has absolutely zero

Speaker:

link to acne or digestive issues.

Speaker:

Unless you're really multitasking. Wrong.

Speaker:

And the idea is that certain foods can kill desire. Well,

Speaker:

that's more about Victorian era shame than

Speaker:

nutritional science.

Speaker:

So let's do myth versus the Kellogg

Speaker:

edition. Fiber prevents sexual

Speaker:

desire. Fiber helps you poop. Your

Speaker:

libido has nothing to do with your bowel movements. Unless you're on the first

Speaker:

date, your colon needs regular

Speaker:

cleansing. Fact, it is self

Speaker:

cleaning. You're not a human swifter,

Speaker:

Kellogg. Cornflakes were invented for help.

Speaker:

They were invented to make you less horrible. Morning.

Speaker:

John Harvey Kellogg was a complex man. A

Speaker:

brilliant surgeon, a health visionary, and frankly, a

Speaker:

zealot. He was obsessed with purity.

Speaker:

A body, a mind, a bowel

Speaker:

on a good side. He adopted a number of kids.

Speaker:

Apparently, he never consummated his own

Speaker:

marriage. And that obsession led to

Speaker:

ideas that were as bizarre as they were

Speaker:

influential. Today, we still live with a

Speaker:

part of his legacy. Every time someone drinks a

Speaker:

detox tea, swears off spices, or

Speaker:

thinks yogurt belongs in the butt, we're seeing a

Speaker:

little ghost of Dr. Kellogg float through the

Speaker:

wellness culture. So here's a lesson, dear listener.

Speaker:

Just because someone's a good doctor doesn't mean

Speaker:

all our ideas are good. Even the best

Speaker:

scalpel can be used to carve

Speaker:

out nonsense.

leave us a five star review if you will, and tell your

Speaker:

colon we said hi. And remember, eat well,

Speaker:

think critically, and if anyone offers you a yogurt

Speaker:

enema, walk briskly in the other

Speaker:

direction. This episode was written and directed by

Speaker:

me, Dr. Terri Simpson. And while I am a board certified

Speaker:

physician, I am not your physician.

Speaker:

If you're going to make any nutritional changes, please talk with a

Speaker:

registered dietitian and a board certified physician.

Speaker:

Not a chiropractor and not some eastern train shame. And they haven't

Speaker:

cured anybody. All things

Speaker:

audio and distribution were by our friends at Simpler

Speaker:

media. And the pod got himself Mr.

Speaker:

Evotera. Until next time, I'm

Speaker:

Dr. Simpson. Stay sharp, stay skeptical,

Speaker:

and remember, yogurt belongs

Speaker:

to start in the mouth.

Speaker:

Hey Ivo, I'm kind of liking some

Speaker:

yogurt based smoothies, but

Speaker:

I drink them.

Speaker:

Oh, thank the gods you didn't make a quip about self

Speaker:

pleasure.

Not everything you put in your mouth is good for you.

There’s a lot of medical information thrown around out there. How are you to know what information you can trust, and what’s just plain old quackery? You can’t rely on your own “google fu”. You can’t count on quality medical advice from Facebook. You need a doctor in your corner.

On each episode of Your Doctor’s Orders, Dr. Terry Simpson will cut through the clutter and noise that always seems to follow the latest medical news. He has the unique perspective of a surgeon who has spent years doing molecular virology research and as a skeptic with academic credentials. He’ll help you develop the critical thinking skills so you can recognize evidence-based medicine, busting myths along the way.

The most common medical myths are often disguised as seemingly harmless “food as medicine”. By offering their own brand of medicine via foods, These hucksters are trying to practice medicine without a license. And though they’ll claim “nutrition is not taught in medical schools”, it turns out that’s a myth too. In fact, there’s an entire medical subspecialty called Culinary Medicine, and Dr. Simpson is certified as a Culinary Medicine Specialist.

Where today's nutritional advice is the realm of hucksters, Dr. Simpson is taking it back to the realm of science.
