FAT. FACTS. FICTION.

What We Cook With. What We’re Really Eating. What the Evidence Says.

Food creates conditions.

Not by itself. Not overnight. And not because one ingredient is perfect or poisonous.

But what we eat repeatedly becomes part of the conditions in which the human system has to grow, function, recover and age.

Fat is a good place to start.

It provides essential fatty acids, helps absorb fat-soluble vitamins, contributes to cell structure and function, and supplies about 9 calories per gram—more than twice the energy density of carbohydrate or protein.

And it is everywhere.

Cooking oils. Restaurant fryers. Dressings. Sauces. Packaged foods. Dairy. Meat. Nuts. Seeds.

So when something this routinely consumed has undergone enormous changes in source, processing, formulation and use, it deserves a closer look.

THAT’S OUR INTEREST.

A World Serious™ isn’t here to sell fear, defend an industry or join another nutrition war.

WE BUILD HEALTHIER LIFE CONDITIONS.

That means understanding what we consume, how it got here, what current evidence actually shows, what remains uncertain—and how to make better decisions with that information.

And it requires one important starting position:

BLIND TRUST IS NOT A HEALTH STRATEGY.

The industrial food supply is also a commercial system.

Manufacturers operate around cost, scale, yield, shelf life, consistency, market share and profit.

Those forces have helped create an extraordinarily abundant, convenient and affordable food supply.

BUT THEY ARE NOT THE SAME THING AS:

WHAT BUILDS THE HEALTHIEST HUMAN OVER A LIFETIME?

Government regulation matters.

Food-safety standards matter.

Industry innovation matters.

But neither regulatory acceptance nor widespread commercial use proves that a provision is optimal across decades of human life.

History has already taught us that.

Artificial trans fat is one example.

Products containing partially hydrogenated oils became ordinary parts of the American food supply long before the evidence ultimately led FDA to determine in 2015 that PHOs were no longer

Generally Recognized as Safe.

Regulatory systems themselves are not beyond scrutiny. Government oversight bodies, researchers and public investigations have repeatedly examined regulatory gaps, conflicts of interest, industry influence, enforcement limitations and delayed action across the food system.

That doesn't mean every manufacturer is dishonest.

It doesn't mean every regulator is compromised.

And it certainly doesn't mean everything industrially produced is dangerous.

IT MEANS WE DON'T OUTSOURCE OUR JUDGMENT.

Blind distrust isn't intelligence either.

We respect a fundamental rule of science:

CORRELATION IS NOT CAUSATION.

The transformation of the American food supply does not prove that one oil or fat caused obesity, diabetes, cardiovascular disease, metabolic dysfunction or other chronic conditions.

But correlation isn't where responsible inquiry ends.

IT'S WHERE BETTER QUESTIONS BEGIN.

Within a few generations, we substantially changed the sources, processing, composition and delivery of dietary fats.

Commercial interests exist.

Industry lobbying exists.

Conflicts of interest exist.

Regulatory limitations exist.

And definitive, decades-long controlled nutrition research in free-living humans is extraordinarily difficult.

SO WE KEEP THINKING.

We follow the evidence.

We examine the process.

We identify the incentives.

We disclose uncertainty.

We distinguish association from causation.

And when better evidence changes the answer, we change the answer.

FOLLOW THE HISTORY. FOLLOW THE PROCESS. FOLLOW THE EXPOSURE.

FOLLOW THE EVIDENCE.

THEN BUILD THE CAPACITY TO CHOOSE.

Because the objective isn't winning an argument about fat.

IT'S BUILDING HEALTHIER CONDITIONS FOR LIFE.

YOU ORDERED THE CHICKEN.

YOU ORDERED THE OIL TOO.

Deep frying doesn't simply cook food.

THE OIL BECOMES PART OF IT.

And while dinner is frying, that oil is exposed to:

High heat. Oxygen. Water. Food particles. Time. Repeated use.

The chemistry changes.

Oxidation. Hydrolysis. Polymerization.

As frying oil degrades, secondary oxidation products—including aldehydes—can form.

GROUNDING FACT

Fresh cooking oil and repeatedly heated fryer oil are not the same provision.

GROUNDING EVIDENCE-BASE

Naser Bazina et al. | School of Health & Life Sciences, Teesside University | 2025 | Food Science & Nutrition

Bazina and colleagues reviewed contemporary deep-frying science and identified oxidation, hydrolysis and polymerization as major degradation pathways. Fatty-acid composition, temperature, oxygen, moisture, food and frying duration all influence deterioration.

THE PRACTICAL PROBLEM?

You usually don't know the history of restaurant fryer oil.

What oil?

How old?

How hot?

How many heating cycles?

How well maintained?

That's not an accusation.

IT'S MISSING INFORMATION.

And missing information should affect the decision.

At home, you control the fat, heat, amount, cooking method and reuse.

Roast. Grill. Bake. Broil. Sauté.

Fry when frying earns its place.

CONTROL IS CAPACITY.

WE DIDN'T STOP EATING FAT.

WE CHANGED THE FAT.

Go back roughly fifty years.

Americans were already eating substantial amounts of dietary fat.

Previous generations weren't living in a fat-free nutritional paradise.

THEY ATE FAT.

What changed dramatically across the twentieth century was where much of that fat came from, how it was produced and how extensively it entered the manufactured food supply.

Soybean oil provides one of the clearest examples.

Historical dietary reconstruction found estimated U.S. soybean-oil consumption increased more than 1,000-fold between 1909 and 1999.

Linoleic-acid availability increased dramatically alongside it.

Historical tissue measurements also reported substantial increases in linoleic acid in human adipose tissue and breast milk.

Does that prove soybean oil caused modern chronic disease?

NO.

But it establishes something important:

OUR EXPOSURE CHANGED.

A major component of the American diet changed substantially within only a few generations.

That deserves examination.

Not panic. Not dismissal.

GROUNDING FACT

The modern American fat supply is materially different from the one previous generations consumed.

GROUNDING EVIDENCE-BASE

·      Tanya L. Blasbalg, PhD; Joseph R. Hibbeln, MD; Christopher E. Ramsden, MD et al. | NIH Section on Nutritional Neuroscience | 2011 | American Journal of Clinical Nutrition - The researchers reconstructed U.S. fatty-acid availability using 373 food commodities spanning 1909–1999 and documented the extraordinary rise of soybean oil and linoleic-acid availability in the American food supply.

THAT DOESN'T TELL US TO GO BACKWARD.

IT TELLS US TO PAY ATTENTION.

HOW DID IT CHANGE SO FAST?

WE LEARNED HOW TO ENGINEER FAT AT SCALE.

Cottonseed became shortening.

Hydrogenation transformed liquid oils into solid fats.

Solvent extraction increased production efficiency.

Refining produced inexpensive, neutral, consistent and shelf-stable oils.

These technologies solved real commercial and practical problems:

Cost. Scale. Consistency. Availability. Shelf life.

And yes:

PROFITABILITY.

Profit isn't inherently corrupt.

Businesses have to make money.

BUT INCENTIVES MATTER.

A product can be extraordinarily successful at being cheap, stable, convenient, scalable and profitable without those characteristics answering a different question:

IS THIS THE BEST PROVISION FOR HUMAN HEALTH?

Partially hydrogenated oils give us a historical warning.

They became deeply embedded in processed food and were the primary dietary source of artificial trans fat.

Then the evidence caught up.

In 2015, FDA determined that PHOs were no longer Generally Recognized as Safe.

GROUNDING FACT

Commercial success, widespread use and regulatory acceptance do not end scientific inquiry.

GROUNDING EVIDENCE-BASE

·      U.S. Food & Drug Administration | 2015–2023 | Partially Hydrogenated Oils  After reviewing extensive scientific evidence, FDA removed PHOs' GRAS status. FDA identifies artificial trans fat as raising LDL cholesterol and increasing cardiovascular risk.

THAT HISTORY MATTERS.

Not because every modern ingredient is the next trans fat.

Because it demonstrates something much simpler:

BLIND TRUST IS NOT A HEALTH STRATEGY.

NOW FLIP THE BOTTLE.

“Vegetable oil.”

Sounds simple.

The manufacturing process may not be.

Depending on the oil, production can involve:

Extraction. Degumming. Refining. Bleaching. Deodorization.

Some conventional extraction systems use hexane, a petroleum-derived solvent.

That does not mean the finished oil is petroleum.

But the picture of a plant on the front of the bottle doesn't tell you the manufacturing story behind it.

Very-high-temperature industrial refining can also form process contaminants including 3-MCPD esters and glycidyl esters.

GROUNDING FACT

How an oil is manufactured can change the provision that reaches your kitchen.

GROUNDING EVIDENCE-BASE

·      U.S. Food & Drug Administration | Human Foods Program | Process-Contaminant Research FDA identifies 3-MCPD esters and glycidyl esters as contaminants that can form during very-high-temperature industrial refining of edible oils and continues analytical testing, monitoring and mitigation work involving these compounds.

Again:

That doesn't make every refined oil dangerous.

IT MAKES PROCESSING RELEVANT.

What was extracted?

How?

Was it refined?

What is its fatty-acid profile?

How fresh is it?

How was it stored?

How are you going to use it?

THE INGREDIENT NAME IS ONLY THE BEGINNING.

AND THIS IS WHERE THE SEED-OIL WAR FALLS APART.

"SEED OIL" ISN'T ONE PRODUCT.

Fresh, cold-pressed sesame oil finishing vegetables is not the same provision as commodity frying oil sitting under commercial heat for hours.

SAME CATEGORY.

VERY DIFFERENT PROVISION.

Cold pressing can preserve naturally occurring compounds that more intensive processing may reduce.

But cold pressed doesn't automatically mean better for every job.

Some highly polyunsaturated specialty oils are more oxidation-sensitive and make more sense cold or at lower temperatures.

Then there's another distinction worth knowing:

HIGH-OLEIC.

High-oleic sunflower and safflower oils have different fatty-acid profiles from conventional high-linoleic versions and generally greater oxidative stability.

Organic?

Useful information about agricultural production.

But organic alone does not establish nutritional superiority.

GROUNDING FACT

"Seed oil" is too broad a category to determine an oil's quality, processing, stability or best use.

STOP ASKING:

ARE SEED OILS BAD?

Start asking:

Which seed? Which process? Which fat profile? Which temperature? Which purpose?

THAT'S PROVISIONS INTELLIGENCE.

THE STORY IS BIGGER THAN CHOLESTEROL.

YOUR GUT AND BRAIN ARE TALKING.

For decades, conversations about dietary fat centered heavily on:

Calories. Weight. Cholesterol. Heart disease.

Those still matter.

But they aren't the whole human system.

The gut contains a vast microbial ecosystem.

Diet helps shape that environment.

Microbes produce metabolites.

Those metabolites interact with intestinal cells, metabolism and immune signaling.

And the gut communicates with the brain through neural, endocrine, metabolic and immune pathways.

FOOD DOESN'T STOP AT YOUR STOMACH.

That expands the health conversation beyond weight and cholesterol into metabolism, immune signaling, cognition and emotional functioning.

Current science is examining how diet influences the microbiome and how those changes may interact with metabolism, cognition and emotional functioning.

Some of that science is still emerging.

THAT MEANS WE KEEP LEARNING.

GROUNDING FACT

Diet helps shape the gut microbial environment—and the gut and brain are biologically connected.

GROUNDING EVIDENCE-BASE

·      Elizabeth Schneider; Kenneth J. O'Riordan; Gerard Clarke; John F. Cryan, PhD | APC Microbiome Ireland, University College Cork | 2024 | Nature Metabolism - Their review examines the diet–microbiota–gut–brain axis, including how diet influences microbial composition and function and how those changes may interact with cognition and emotional functioning.

THIS ISN'T A REASON TO FEAR FAT.

IT'S A REASON TO GET BETTER AT CHOOSING IT.

SO WHAT SHOULD ACTUALLY BE IN YOUR KITCHEN?

Enough theory.

YOU NEED A FEW PROVISIONS YOU UNDERSTAND.

EXTRA-VIRGIN OLIVE OIL | THE WORKHORSESauté. Roast. Dress. Marinate. Finish.

AVOCADO OIL | GOOD. NOT MAGIC.Neutral and versatile when those characteristics are useful.

HIGH-OLEIC OILS | READ ONE WORD FURTHER.High-oleic sunflower and safflower can be useful neutral cooking options.

COLD-PRESSED SEED + NUT OILS | PURPOSE MATTERS.Sesame. Walnut. Flax. Pumpkin seed. Give them the right job.

BUTTER | KEEP IT.Use it where butter earns its place.

BACON FAT | YOU ALREADY PAID FOR IT.Strain it. Store it safely. Use it where the flavor matters.

LARD + TALLOW | OLD SKILLS. REAL USES.Keep the skill. Lose the mythology.

BUILD YOUR CORE THREE.

EVERYDAY: Extra-Virgin Olive Oil

SECOND COOKING OPTION: Quality avocado oil or an appropriate high-oleic oil

FLAVOR + PURPOSE: Butter, bacon fat, lard, tallow or a specialty cold-pressed oil

THREE PROVISIONS YOU UNDERSTAND BEAT TWELVE BOTTLES YOU DON'T.

BUT WE'RE LOSING SOMETHING BIGGER THAN THE FAT.

THE SKILL.

We throw bacon fat away.

Then buy another cooking fat.

We pay extra for beautiful bottles because somebody put "healthy," "natural" or "premium" on the label.

We leave oils in the cabinet until they're stale.

And we're becoming exceptionally good at acquiring food without necessarily knowing how to turn basic provisions into a meal.

Food knowledge used to travel through families.

How to render.

How to roast.

How to store.

How to stretch a meal.

How to use leftovers.

How to feed people.

Those weren't quaint traditions.

THEY WERE LIFE SKILLS.

Teach someone to understand food and you've given them the capacity to:

Choose. Cook. Save. Adapt. Waste less. Feed themselves.

And perhaps someday feed somebody else.

THAT'S WHERE FAT BECOMES GENERATIONAL.

FAT. FACTS. FICTION.

The evidence didn't tell us:

FAT IS BAD.

It didn't tell us:

SEED OILS ARE POISON.

And it certainly didn't tell us:

BUTTER AND TALLOW FIX EVERYTHING.

THE STORY IS MORE USEFUL THAN THAT.

FAT IS A PROVISION.

Where it came from matters.

How it was produced matters.

Its composition matters.

Freshness matters.

Storage matters.

Heat matters.

Frequency matters.

KNOW THE FAT.

KNOW THE PROCESS.

KNOW THE PURPOSE.

THEN USE IT WELL.

Because healthier conditions aren't built through fear.

And they aren't built through blind trust.

They're built through better-informed decisions repeated over time.

BETTER PROVISIONS.

HEALTHIER CONDITIONS.

GREATER HUMAN CAPACITY.

A World Serious™ builds the capacity to solve problems, create sustainable results, and thrive personally, professionally, and relationally.

Personal. Professional. Generational.

PROVISIONS PROCUREMENT PROTOCOL

PPP | PI.001

THE 60-SECOND FAT BUYER

BUY THE PROVISION. NOT THE BRAND STORY.

Higher price ≠ automatically better.Store label ≠ automatically worse.Organic ≠ automatically nutritionally superior.Famous ≠ automatically higher quality.

01 | EXTRA-VIRGIN OLIVE OIL

LOOK FOR: Extra Virgin + harvest date + traceable origin + dark/opaque packaging.

AWS TARGET: 12–18 months from harvest or fresher when practical.

AVOID: Old harvests, vague origin, poor light protection and oversized containers.

BUYER TIP: Harvest date and best-by date are not the same thing.

VALUE: A fresh store-label or lesser-known EVOO meeting the standards can beat an older prestige bottle.

02 | AVOCADO OIL

LOOK FOR: Avocado oil as the actual oil + clear information + protective packaging.

AVOID: Vague blends and health-halo pricing.

BUYER TIP: Ignore the avocado picture. Read the ingredients.

VALUE: Don't pay the premium unless you need what avocado oil does.

03 | SUNFLOWER + SAFFLOWER

LOOK FOR: HIGH OLEIC.

AVOID: Assuming every version is equivalent.

BUYER TIP: Those two words matter more than the flower.

VALUE: Store labels can be excellent when the specifications match.

04 | COLD-PRESSED SEED + NUT OILS

LOOK FOR: Specific oil + appropriate processing + protective packaging + practical size.

AVOID: Huge bottles and using every specialty oil at high heat.

BUYER TIP: What am I buying this for?

VALUE: Small and fresh beats large and forgotten.

05 | BUTTER

LOOK FOR: Primarily cream, plus salt when desired.

AVOID: Confusing butter-flavored spreads with butter.

BUYER TIP: Read ingredients, not adjectives.

VALUE: Straightforward store-label butter can do the job perfectly well.

06 | LARD + TALLOW

LOOK FOR: Clearly identified animal fat + short ingredient list.

AVOID: Paying a lifestyle premium without reading the container.

BUYER TIP: Tallow = beef fat. Lard = pork fat.

VALUE: Traditional fats were practical foods before they became fashionable products.

07 | BACON FAT

LOOK FOR: Your own kitchen.

BUYER TIP: Strain it. Store it safely. Use it intentionally.

VALUE: USE MORE. WASTE LESS.

08 | "VEGETABLE OIL"

LOOK FOR: The actual oils in the ingredient statement.

AVOID: Assuming "vegetable oil" tells you enough.

BUYER TIP: FRONT: MARKETING. BACK: INFORMATION.

VALUE: Generic isn't automatically bad. Evaluate the provision.

09 | FRYING

LOOK FOR AT HOME: Fresh oil suited to the job.

LIMIT: Commercial fried foods becoming a frequent source of repeatedly heated fat.

BUYER TIP: At a restaurant, you usually don't know the oil's identity, age or heating history.

VALUE: Home cooking gives you more control over both the provision and the cost.
