The Right Stuff: Animal Fat
If you’re like most people, you’re sadly unaware of the tremendous benefit of healthy fats, especially saturated fat.
For years, saturated fat—the kind found in animal products such as eggs, meat, and dairy—was maligned as a primary cause of cardiovascular disease and mortality.
The progenitor of this association was Ancel Keys, a physiologist at the University of Minnesota. In the 1950s, he published a landmark series of papers using small feeding experiments (in animals) to show a direct relationship between serum cholesterol levels and clogged arteries, and observational studies of a few European countries that appeared to show a direct correlation between saturated fat intake and the incidence of heart attacks.
On the strength of Keys’ aggressive personality and his relationship with Paul Dudley White, cardiologist and personal doctor for President Eisenhower, Keys made his way into the nutrition committee of the American Heart Association. With little evidence, he successfully got the association to adopt his anti-saturated-fat hypothesis as official policy. From 1961, the AHA recommended decreased consumption of saturated fats and their replacement with polyunsaturated (i.e., vegetable) oils.
The impact of this development cannot be overstated, and it has unfortunately led to a decades-long setback in the country’s—and the world’s—nutritional health. This damage is only recently being undone. Yet the tide is turning, and new research highlights the benefit of healthy fats, particularly those from animal sources. These once-vilified fats are finally getting the credit they deserve for their critical role in a balanced diet.
Animal Fats Are Nutrient-Dense Powerhouses
Animal fats are more than just a source of calories—they’re packed with essential vitamins and nutrients.
- Egg yolks are rich in vitamins A, D, E, and K2, which support immune function, bone health, and cellular regeneration.
- Grass-fed butter and lard provide omega-3 fatty acids and fat-soluble vitamins, delivering the benefit of healthy fats for reducing inflammation.
- Dairy products like cheese and cream combine beneficial fats with calcium and other key minerals.
These nutrients are often more bioavailable (easier for your body to absorb) than those in plant-based sources, making animal fats a superior choice for nourishing your body.
Healthy Hormone Production Depends on Dietary Fats
Your body needs fat to produce hormones like testosterone, estrogen, and cortisol. Saturated fats and cholesterol from animal products provide the benefit of healthy fats as building blocks for these critical hormones.
Low-fat diets have been linked to hormonal imbalances, mood disorders, and reduced fertility. By eating animal fats, you support optimal hormonal health and overall wellness.
Long-Lasting Energy
Animal fats are a stable energy source. Unlike carbohydrates, which can cause blood sugar spikes and crashes, fats are metabolized more slowly, giving you sustained energy.
For those following low-carb or ketogenic diets, the benefit of healthy fats becomes even more apparent. They fuel the body in the absence of glucose, boosting mental clarity and physical endurance.
Improved Brain Function
Your brain thrives on dietary fats. Cholesterol from animal products supports the production of myelin, aiding faster communication between neurons. Omega-3 fatty acids in fatty fish and grass-fed meats enhance cognitive health, offering the benefit of healthy fats for memory, focus, and mood.
Delicious and Satiating
Animal fats don’t just nourish—they make food taste incredible! Whether it’s the creamy richness of butter or the satisfying sizzle of bacon, these fats enhance meals while providing the benefit of healthy fats in helping you feel fuller for longer.
How to Add More Animal-Based Fats to Your Diet
- Breakfast: Cook your eggs in butter or bacon grease.
- Snacks: Swap sugary treats for hard cheeses and full-fat yogurt to enjoy the benefit of healthy fats while staying fuller longer.
- Cooking: Use tallow, lard, or ghee instead of vegetable oils.
Quality Matters: Choose grass-fed, organic, and pasture-raised animal products for maximum nutrition.
Final Thoughts
Embracing the benefit of healthy fats doesn’t mean ignoring balance.It’s about moving away from outdated dietary dogma and embracing nutrient-rich, whole foods that our bodies are designed to thrive on.
Whether it’s the richness of a farm-fresh egg yolk or the satisfying flavor of grass-fed butter, animal-based fats offer a wealth of health benefits that can transform your diet and overall well-being. So, don’t shy away from these wholesome, traditional foods—your body (and taste buds) will thank you!
