For about 50 years, animal fat was public enemy number one. Doctors warned against it. Food companies replaced it with vegetable oils and trans fats. Grocery shelves filled up with "low-fat" everything.
And yet — chronic disease rates climbed. Energy crashed. People got hungrier, not healthier.
Something didn't add up.
Where the Fear Came From
The war on animal fat started in the 1960s, largely driven by a single researcher named Ancel Keys. His "Seven Countries Study" claimed a direct link between saturated fat consumption and heart disease. The study was influential — and deeply flawed.
Keys cherry-picked data from countries that supported his hypothesis and ignored data from countries that didn't. Later analyses showed no consistent relationship between saturated fat intake and cardiovascular disease when the full dataset was included.
But the damage was done. The USDA food pyramid was built around the idea that fat was bad and carbohydrates were good. The food industry ran with it — replacing butter with margarine, lard with hydrogenated vegetable oils, and whole foods with processed, low-fat alternatives loaded with sugar.
What Animal Fat Actually Is
Animal fat isn't a single thing. It's a complex mixture of:
Lard, for example, is actually about 45% monounsaturated fat — higher than butter. Tallow from grass-fed beef is rich in CLA and vitamin K2. Duck fat has a fatty acid profile remarkably similar to olive oil.
These aren't junk fats. They're nutrient-dense, ancestral foods that humans have eaten for hundreds of thousands of years.
The Problem With What Replaced It
When animal fat was removed from the food supply, something had to replace it. That something was usually one of three things:
1. Refined vegetable oils — corn, soybean, canola, and cottonseed oils. These are high in omega-6 polyunsaturated fats, which are unstable at high heat and prone to oxidation. When oxidized, they produce aldehydes and other compounds linked to inflammation and cellular damage.
2. Trans fats — partially hydrogenated vegetable oils, created to mimic the texture of animal fat. Trans fats were eventually banned by the FDA in 2018 after being conclusively linked to heart disease. The very thing that replaced "dangerous" animal fat turned out to be genuinely dangerous.
3. Sugar and refined carbohydrates — when fat was removed from food, flavor had to come from somewhere. Sugar filled the gap. The result was a generation of "healthy" low-fat foods that spiked blood sugar, drove insulin resistance, and left people hungry an hour later.
Animal Fat and Satiety
One of the most underappreciated benefits of animal fat is how it affects hunger.
Fat slows gastric emptying — meaning food stays in your stomach longer and you feel full for more hours after eating. It also triggers the release of cholecystokinin (CCK), a hormone that signals satiety to the brain.
Protein and fat together are the most satiating macronutrient combination available. That's why a snack made from real meat — with its natural fat content intact — keeps you satisfied in a way that a rice cake or a handful of pretzels never will.
This is exactly why we don't strip the fat from our snacks. The fat is part of the nutrition. It's part of the flavor. And it's part of why one serving actually holds you over.
The Pork Belly and Chicken Skin Question
Two of our products — Pork Belly Crisps and Chicken Skin Crisps — are essentially pure animal fat, rendered crispy.
We get this question a lot: *Isn't that just eating fat?*
Yes. That's the point.
Pork belly fat is rich in oleic acid (the primary fat in olive oil) and contains meaningful amounts of B vitamins, selenium, and zinc. Chicken skin is high in monounsaturated fat and collagen precursors. Neither is empty calories.
When you render these fats properly — low and slow, without seed oils, without additives — you get a snack that's clean, satisfying, and genuinely nutritious. Two ingredients. Real food. Nothing else.
What the Research Actually Says Now
The scientific consensus has shifted significantly in the last decade. A 2010 meta-analysis published in the *American Journal of Clinical Nutrition* reviewed 21 studies and found no significant evidence that saturated fat is associated with increased risk of cardiovascular disease or stroke.
A 2020 review in the *Journal of the American College of Cardiology* concluded that replacing saturated fat with refined carbohydrates does not reduce cardiovascular risk — and may increase it.
The 2015 Dietary Guidelines Advisory Committee quietly dropped the decades-old recommendation to limit dietary cholesterol, acknowledging it was "not a nutrient of concern."
None of this means you should eat recklessly. Context matters — the quality of the animal, what it was fed, and how the fat is prepared all make a difference. Grass-fed and pasture-raised animals produce fat with a better omega-3 to omega-6 ratio and higher levels of fat-soluble vitamins.
But the blanket condemnation of animal fat? The science doesn't support it.
How to Think About Fat in Your Diet
Here's a simple framework:
Eat fat from real animals. Beef tallow, lard, duck fat, chicken fat, butter, ghee — these are ancestral fats that your body knows how to process.
Minimize industrial seed oils. Corn, soybean, canola, sunflower, and safflower oils are high in omega-6 fats and unstable under heat. They're in almost every processed food. Read labels.
Don't fear fat-forward whole foods. Eggs, fatty cuts of meat, skin-on poultry, and whole-fat dairy are not the enemy. They're some of the most nutrient-dense foods available.
Pair fat with protein. The combination is more satiating than either alone and supports muscle maintenance, hormone production, and sustained energy.
The Bottom Line
Animal fat was never the villain. It was a convenient scapegoat — one that allowed the processed food industry to sell you something cheaper and more shelf-stable while calling it healthier.
Real fat from real animals is fuel. It's flavor. It's nutrition that your body recognizes and knows what to do with.
At Salt & Pepper Co, we build our snacks around that principle. Real meat. Natural fat. Two ingredients. Nothing to hide.
That's not a marketing line. It's just food the way it's supposed to be.
