Debunking Fast Food Myths: The Truth About Hamburgers

“Super Size Me” and the Hamburger’s Reputation: Uncovering the truth about hamburgers can reveal so much more beyond their portrayal in media.

Super Size Me is a 2004 documentary film made, directed, written, and starred in by Morgan Spurlock.
In 2003, for 30 days straight, he ate only McDonald’s for breakfast, lunch, and dinner, and filmed what happened to his body.

Doctors monitored changes in his physical and mental health and used his case to highlight the negative effects of fast food.

Every time they offered to “super size” the meal, he had to say yes.

On that diet he was taking in about 5,000 calories a day – the equivalent of eating 9.26 Big Macs every single day.

What if you ate only one “healthy” food?

Now let’s flip the question.

What would happen if you took a traditional Korean food – even something we think of as healthy – and ate only that one dish, three times a day, for a whole month?

Honestly, we don’t even need to run the experiment to know the outcome.

If you ate samgyetang (ginseng chicken soup), a food most Koreans consider a health food,
3 times a day at 5,000 calories each day…
well, that’s not going to end well either.

Whether you drink 2,000 cc of cola every day or 2,000 cc of orange juice,
if you consume that much, it won’t make a huge difference in the end.

A surprising experiment: what’s the “best” single food?

Here’s another interesting experiment.

Imagine this list of foods:

• Corn
• Hot dogs
• Spinach
• Peaches
• Bananas
• Milk chocolate
• …

If you had to pick just one food from this list and live on only that food for a year,
what would you choose?

In a survey:

• 42% of people chose bananas
• 27% chose spinach

But the real number one food is far from what most people guessed.

The actual winner was… hot dogs.
(Only 4% of respondents picked hot dogs!)

Personally, I’m more impressed by the fact that someone could eat only hamburgers,
5,000 calories a day, for 30 days straight and get through it at all.

“Good” foods vs “bad” foods: apples vs hamburgers

Let’s look at how people judge “good” and “bad” foods.

In one experiment, participants were asked to rate foods based only on their names.
Not surprisingly, apples and carrots were instantly labeled as “healthy foods,”
while hamburgers were considered junk.

But when the names were covered up and people were shown only the nutrition labels,
a funny thing happened:

Many people picked the hamburger as the more nutritious option.

Why?
Because in terms of vitamins and minerals, a Big Mac actually beats an apple by a mile.

• A Big Mac contains 13 essential vitamins and minerals
• An apple has basically only vitamin C

And yet, more than 80% of students still chose the apple as the “healthy” option.
Female students, in particular, had even stronger faith in apples than male students.

It’s not exactly shocking.
We’ve all heard over and over again that:

• Fast food is junk food
• Big Macs are the symbol of “empty calories” and “no nutrition”

So our image of food often has more power than the actual nutrition facts.

“In Defense of the Hamburger” – Prof. Yoon Bang-Bu

There’s a well-known piece by Professor Yoon Bang-Bu titled:

“In Defense of the Hamburger”
“As a staple food, the nutrition balance is fine, and you don’t have to fear obesity.”

Prof. Yoon Bang-Bu

• Born in 1943, Seoul
• MD and PhD from Yonsei University College of Medicine
• Family medicine specialist (trained at University of Minnesota)
• Founding director of the Korean Academy of Family Medicine
• Former vice president of the World Organization of Family Doctors (WONCA)
• Currently professor at Yonsei University College of Medicine, UN-designated physician
• Author of Principles of Family Medicine, Emergency Health Diagnosis with Prof. Yoon Bang-Bu, etc.

At some point, hamburgers became a kind of public enemy.

The media has no hesitation calling hamburgers:

• “The main culprit of obesity”
• “The cause of lifestyle diseases”

So, are hamburgers really inherently harmful?

If we jump to the conclusion first:

That’s basically a false accusation.

A hamburger is actually a nutritionally well-balanced food,
and if you eat it properly, there’s no reason it has to make you fat.

Korean food myths and the “well-being” craze

Before talking more about hamburgers, I want to touch on something else:

The prejudices Koreans have about food,
and the widespread misconceptions about “healthy eating.”

In Korea, there’s an endless stream of so-called health tips, miracle diets, and folk remedies
that have no scientific basis whatsoever.

Some are wrapped in fancy “theories,”
but when you strip them down, they’re basically superstition.

These days, with the whole “well-being” trend,
TV programs that teach you how to “eat only the right things” are hugely popular.

In that environment:

• Some foods get elevated to “cure-all, anti-aging superfoods”
• Others are demonized as “absolutely avoid at all costs” poisons

Prejudice around food is getting stronger and stronger.

---

TV, vegetarianism, and miracle diets

Not long ago, a TV show introduced vegetarianism
as if it were the ultimate secret to health.

This “vegetarian supremacy” fad once swept through the US too.

A doctor named Stuart Berger went on TV and claimed:

“If you eat a vegetarian diet and take vitamins,
you can prevent cancer, lifestyle diseases, and many chronic illnesses.”

Celebrities, politicians, and the wealthy followed him devotedly,
and he became a star overnight.

He even created his own “immune-boosting” diet product,
the Southampton Diet, and made a fortune from it.

But in March 1994, he died suddenly at the young age of 40.

Another example: Mr. Rodale, publisher of Forever Young magazine.

He often appeared on TV talking about food and health.

He famously boasted:

“I’m in my seventies, but I regularly eat bone-based supplements,
so my bones are so strong they almost never break.”

What does proper nutrition really look like?

According to mainstream medical research,
the ideal macronutrient ratio for daily intake is roughly:

• Carbohydrates: 50%
• Fats: 30%
• Protein: 20%

People need to get away from TV-driven myths about:

• “Pure vegetarianism = automatically healthy,”
• “Natural foods = always good,”
• and all-or-nothing thinking.

In the West, people lean toward meat-heavy diets.
In the East, especially Korea, people are still largely plant-based,
except for a small portion of heavy meat eaters.

So for many Koreans, the problem is not “too much meat,”
but often not enough animal protein.

If I had to recommend only one of the two
(meat vs vegetables) to Koreans as a group,
I’d honestly say:

“Eating more meat would probably be better for your health.”

In reality, Westerners who eat more meat often have
better stamina and live just as long—if not longer—than many Koreans.

“Health food” obsession and Korean eating habits

I once treated a patient with acute pancreatitis caused by heavy drinking.
Even after continuous treatment, he wasn’t improving.

It turned out he had secretly been eating “healthy foods” people told him about.

When I said, “I told you to fast! Why do you keep eating?”
his caregiver said:

“But doctor, how can he recover if he’s starving? Food is the most important thing!
So I’ve been feeding him pine nut porridge because it’s good for him.”

In the US, if a patient has mild infectious diarrhea,
doctors often say:

“It’s probably viral. Fast for a day and just drink things like Coke or 7-Up.”

If it doesn’t get better, they might extend the fasting another day.

American patients generally follow those directions.

But in Korea?

Diarrhea patients often say things like:

• “How can I work if I only drink barley tea? Give me anti-diarrheal meds.”
• “Please give me a nutrition drip.”
• “At least let me eat rice porridge.”

Many Koreans believe:

“If a food is ‘good for you,’ you can eat it anytime, as much as you want,
and it will always be beneficial.”

That mindset can actually damage your health.

Another common Korean pattern:
If TV reports that “a certain food may cause a certain disease,”
that food is instantly labeled a “harmful food.”

From that point on,
many people believe that all illnesses are caused by that one food.

Perfectly fine foods suddenly become targets of hate.

Hamburgers are one of the biggest victims of this kind of prejudice.

What is a hamburger, really?

A hamburger is a food you can eat without knives, forks, or chopsticks.
Convenience is one of its biggest advantages.

The question is:

What about its nutritional content?

Typically, a hamburger patty is made from:

• Ground beef
• Egg
• Bread crumbs
• Sautéed onion

It’s shaped into a flat, round patty and cooked thoroughly in a pan.

That patty is then placed inside a wheat bun
with lettuce, onion, tomato, salt, pepper, ketchup, and so on.

And that’s your hamburger.

---

The surprising origins of hamburgers

We think of hamburgers as a Western food,
but their roots actually trace back to medieval Central Asia.

The Mongols, who conquered the Eurasian continent,
had a traditional minced meat dish.

That dish spread to Eastern Europe (places like Hungary),
where it became known as “tartar steak.”

German merchants based around Hamburg brought it into Germany,
and over time, tartar steak evolved into Hamburg steak.

In 1904, at the St. Louis World’s Fair in the US,
Hamburg steak was commercialized as a convenient food for the masses.

The fair was packed, and one overwhelmed cook
started serving Hamburg steak between two round pieces of bread.

That eventually evolved into what we know today:

• A bun
• A patty
• With ketchup, mustard, and other toppings

The modern hamburger.

What’s actually inside a hamburger?

Take one big global chain, “M.”
Their burger lineup includes:

• Big Mac
• McFeast (or McWhopper-style burgers)
• Regular hamburger
• Cheeseburger
• Double cheeseburger / double hamburger
• McChicken
• Fish burger
• Shrimp burger
• Bulgogi burger
• McRib Jr., etc.

Roughly:

• Big Mac / cheeseburger / hamburger / double burgers / McFeast = beef
• McChicken / Shanghai spicy = chicken
• Fish burger = fish
• Bulgogi burger / McRib = pork

Calorie-wise:

• Big Mac: ~590 kcal
• Regular hamburger: ~280 kcal
• McChicken: ~520 kcal
• Bulgogi burger: ~425 kcal

A regular hamburger (about 105 g) roughly contains:

• Carbs: 35 g (about 11% of daily recommended intake)
• Protein: 12 g (about 20%)
• Fat: 10 g (about 20%)
• Cholesterol: 30 mg (about 10%)
• Calcium: 150 mg (about 21%)

For teens aged 10–19, based on estimated daily energy needs:

• Boys would need ~7–9 regular hamburgers a day
• Girls ~7–8 hamburgers a day

to meet their full daily calorie requirement.
(Not that anyone should actually do that.)

Looking at fat:

• About 5 burgers to hit the full daily fat limit
• About 10 burgers to hit the full daily cholesterol intake

If we compare total calories:

• 1 Big Mac (590 kcal) is similar to:
  • Samgyetang (700 kcal)
  • Jajangmyeon (670 kcal)
  • Soft tofu stew set (580 kcal)
  • Seolleongtang (470 kcal)

So in terms of energy, a burger is not some uniquely monstrous outlier.

Seven common accusations against hamburgers

Let’s walk through the typical criticisms one by one.

---

1. “Hamburgers are harmful to your health.”

In reality, human health and disease are not determined by the type of food alone.

The real problems are:

• Overeating
• Extreme picky eating
• How the food is cooked
  • Very spicy
  • Very salty
  • Burnt/grilled to charring

These patterns are strongly linked to heart disease, kidney disease,
and digestive diseases including stomach cancer.

So merely eating hamburgers does not automatically ruin your health.
Like any other food, if you eat too much, it becomes a problem.

The same is true of any food.

---

2. “Hamburgers cause nutritional imbalance.”

The best way to protect your health is to eat a varied, balanced diet.

A hamburger actually contains a mix of:

• Carbohydrates
• Protein
• Fat
• Calcium

You get bread, meat, and vegetables (tomato, lettuce, onion) all in one bite.
It doesn’t naturally promote picky eating.

Of course, if you eat only hamburgers and nothing else,
that’s not a good idea.

But that’s true of any single food.

If you compare “only hamburgers” vs “only one traditional dish,”
hamburgers aren’t necessarily worse; in some ways they might be a little better,
simply because they’re made of more mixed ingredients.

Again, the ideal macronutrient ratio is:

• Carbs 50%
• Fat 30%
• Protein 20%

A regular hamburger has:

• Carbs: 35 g
• Protein: 12 g
• Fat: 10 g

So it’s not perfect, but it’s reasonably close.

You can fairly say it’s a relatively well-balanced food.

---

3. “Hamburgers make you fat.”

This is what people worry about most.

TV loves to hammer the message:

“Eat hamburgers → you get fat.”

But to talk seriously about hamburgers and obesity,
you need to understand what obesity actually is.

Obesity is a kind of disease.

Sometimes genetics play a role,
but in most cases it’s about energy imbalance:

You eat more calories than you burn.

Visceral obesity (belly fat around the organs),
common in middle-aged adults, is linked to:

• Aging
• Overeating
• Lack of exercise
• Genetic factors

In general, medical research suggests the causes of obesity are roughly:

• 30% genetic
• 10% cultural
• 60% environmental/lifestyle

In short:

We eat too much and move too little.

For internal fat-type obesity,
things like too much sugar, drinking, and smoking are especially problematic.

Crash dieting is one option,
but most strict diets fail, don’t last, and cause stress and health problems.

What really matters is:

Keep your total daily intake around the recommended ~2,000 kcal for adults.

A Big Mac has 590 kcal, while a regular hamburger has 280 kcal.

Compared with many other dishes,
their calorie and nutrient balance aren’t particularly extreme.

So the idea that:

“Hamburgers automatically cause obesity”

is simply not accurate.

It’s not what you eat; it’s how much.

---

4. “Hamburgers raise your cholesterol.”

There’s a common belief that hamburgers drive up cholesterol
and cause all kinds of illnesses.

In reality, cholesterol:

• Is partly produced by your body itself
• Is partly made in the liver from the fats you eat

Cholesterol isn’t purely evil.

It’s essential for:

• Cell membrane structure
• Bile production
• Hormone synthesis
• Enzyme production
• Sperm production

It only becomes a problem when it leads to hyperlipidemia (high blood lipids)
and atherosclerosis (artery hardening).

Hyperlipidemia generally means:

• Total cholesterol ≥ 240 mg/dL, or
• Triglycerides ≥ 200 mg/dL

When there’s too much fat in the blood,
it sticks to artery walls, narrows the vessels,
and makes them stiff.

To manage hyperlipidemia, the basics are:

• Maintain a normal body weight
• Avoid overeating
• Exercise regularly

You don’t have to obsess over specific foods,
but low-fat choices can help.
If your triglycerides are especially high,
you should limit sweet foods (syrups, candy, ice cream, etc.)
and definitely avoid alcohol.

Exercise is extremely helpful:
it lowers triglycerides and raises “good cholesterol” (HDL).

These days, there are also effective medications for hyperlipidemia.

Foods especially high in cholesterol include:

• Dried squid
• Fish roe
• Egg yolks
• Organ meats like intestines

Lean beef, pork, and chicken generally have relatively lower cholesterol.

Best cholesterol range is roughly 160–180 mg/dL.
Too low can also increase bleeding risk.

One Big Mac contains around 34 mg of cholesterol,
about 28% of the recommended daily intake.

So eating one Big Mac does not automatically spike your cholesterol.

And since hyperlipidemia has many causes,
it’s hard to blame any one food as the culprit.

---

5. “Hamburgers are too fatty.”

For a Big Mac, the carb:protein:fat ratio is about 47:24:34.
That’s not too far from the recommended 50:20:30.

However, one Big Mac already gives you about 68% of your daily fat limit,
so eating multiple Big Macs a day isn’t advisable from a fat-intake standpoint.

Other burgers are somewhat lower in fat contribution:

• McFeast: ~54% of daily fat per burger
• Regular hamburger: ~20%
• Cheeseburger: ~28%
• McChicken: ~58%
• Bulgogi burger / fish burger: ~40%

So yes, you need to be mindful of portions,
but the picture is more nuanced than “burgers = pure fat.”

---

6. “Hamburgers are unhygienic.”

Most major burger chains run fairly strict quality control systems.

• Regional quality control centers inspect ingredients and processes
• Many international chains use local meat and vegetables
• The patties and ingredients are prepared at local plants and shipped to stores
• Kitchen equipment like grills are regularly cleaned
• Some chains even run “open kitchen” or “open day” events to show how food is made

Of course, hygiene standards differ by brand and location,
but as a category, hamburgers are not uniquely dirty foods.

---

7. “Hamburgers are bad for your liver.”

Markers like GOT, GPT, and γ-GT going up
usually don’t have much to do with any specific food.

Liver function issues are generally not caused by hamburgers.

In fact, in the past, liver patients were sometimes told to eat more meat
to help support their nutrition.

---

So… is a hamburger really the villain?

In my view, hamburgers have become victims of:

• Overhyped “health food” marketing
• Media framing all fast food as “junk food” with no nuance

In Korea especially, people tend to treat hamburgers as snacks,
not meals.

So they eat a full three meals plus a burger on top of that.
Naturally, their daily calorie intake shoots up,
they gain weight, and then blame everything on the hamburger.

Personally, I have fond memories of eating hamburgers with my family
during my 5-year stay in the US.

Even now, I sometimes eat hamburgers in the car, in the office,
or even on the train—
as a meal, not an add-on snack.

---

Real “well-being”: eat what you actually want

I think many Koreans are still trapped in food-related myths and TV drama-style thinking.
Shows like Dae Jang Geum probably became so popular for that reason too.

Of course, we should preserve and develop our traditional food culture.
But obsessively labeling every food as:

• “This is good for you”
• “That is bad for you”

is not healthy.

If you really want a hamburger,
but you stop yourself because:

“TV said if I eat hamburgers, my cholesterol will rise and I’ll get sick…”

That’s not well-being. That’s just unhappiness.

True well-being is:

Being able to eat what you want without unnecessary fear—
while managing quantity, balance, and lifestyle.

Food itself is not inherently good or bad.

The real problems are:

• Overeating
• Extreme picky eating
• Cooking methods (too spicy, too salty, burnt)
• Not using individual plates (shared dishes and hygiene)
• Smoking
• Heavy drinking
• Not exercising

So:

Eat the burger.
Change the lifestyle.

Then you’re on the fastest path to “eating well and living well.”

The rest?
That part is up to your genes.
