The return of beef tallow: A science-backed investigation

Why Is Everyone Talking About Beef Tallow Again?

From wellness influencers to nose-to-tail chefs, beef tallow is having a moment. Once pushed aside by industrial oils, it is now making a comeback in kitchens and skincare routines. Promoted as a clean, nutrient-dense fat with ancestral roots, beef tallow is praised for everything from searing steak to moisturizing dry skin. But is this just another wellness fad, or does the science actually back it up?

Let’s explore what modern research tells us about this traditional fat — and whether its comeback is justified.

What Is Beef Tallow?

Beef tallow is the rendered fat from cattle, typically collected from suet or subcutaneous fat. When gently heated and filtered, it transforms into a smooth, shelf-stable fat with a creamy consistency and neutral flavor. For centuries, tallow was used for cooking, skincare, candles, and even healing salves.

Today, Wagyu beef tallow — made from highly marbled Wagyu cattle — offers an upgraded version of this classic fat. With a superior fat profile and rich taste, it stands apart in both health and culinary applications.

What's Actually in Beef Tallow?

Tallow is nearly pure fat, but the type of fat matters. Based on USDA and National Research Council data, its composition typically includes:

Saturated fats like palmitic and stearic acid
Monounsaturated fats, primarily oleic acid
Small amounts of polyunsaturated fats, including linoleic acid and omega-3s
It also contains fat-soluble vitamins A, D, E, and K, as well as conjugated linoleic acid (CLA), a compound studied for its potential anti-inflammatory and fat-modulating effects. Its high smoke point of roughly 480°F also makes it ideal for high-heat cooking.

Is Tallow Actually Good for Your Skin?

One of the more surprising uses of tallow is skincare. At first glance, rubbing beef fat on your face may sound strange, but there’s logic behind it.

The fatty acid structure of tallow closely resembles the natural sebum produced by our skin. That means it absorbs well and helps reinforce the skin barrier, particularly in dry or sensitive skin types. Some studies have shown that tallow-based formulations can increase plasma fatty acid levels, suggesting good absorption.

Still, dermatologists caution that tallow may clog pores for those with oily or acne-prone skin. While its vitamin E content can calm irritated skin, its use is best suited to individuals with dry or reactive skin types.

What About Eating It?

Beef tallow is back in the kitchen, but is it good for your body?

Traditional nutrition guidelines warn against saturated fats, linking them to higher cholesterol and heart disease risk. However, not all saturated fats act the same way. Stearic acid, which makes up a portion of beef tallow’s fat, is known to have a neutral effect on cholesterol levels. And the dominant fat in Wagyu beef tallow, oleic acid, is also the heart-healthy fat found in olive oil.

A 2020 meta-analysis found that natural fats from ruminant animals, like tallow, may have significantly less impact on cardiovascular risk than industrial seed oils or artificial trans fats. While the research is still ongoing, moderate use of high-quality tallow within a whole food diet appears to be safe for most healthy individuals.

Grass-Fed vs. Grain-Fed Tallow

Does the source of the fat matter? Yes.

Grass-fed beef tallow, especially from Wagyu cattle, contains more omega-3s, CLA, and antioxidants compared to grain-fed varieties. Research has shown a much better omega-6 to omega-3 ratio in grass-fed tallow, sometimes as low as 1.4 to 1, which supports lower inflammation and healthier lipid profiles.

Grass-fed tallow may also contain more vitamin K2, a nutrient linked to heart and bone health. Though it’s still fat, it’s a cleaner, more nutrient-dense version of the same product.

What About the Anti-Inflammatory Claims?

CLA is often mentioned as one of the major perks of using tallow. This naturally occurring fat has shown potential anti-inflammatory effects in both animal and human studies. It may support fat loss, reduce inflammation, and improve metabolic markers.

So, Is Tallow a Superfood?

It depends on how you define that term.

Beef tallow, especially from Wagyu cattle, is nutrient-rich, heat-stable, and ancestral. It works exceptionally well for cooking and, in some cases, skincare. It is full of vitamins and healthy fats that can support hormone production and energy metabolism.

At the same time, it should be used mindfully within a balanced diet. It is not a magic bullet, but it’s also far from the unhealthy villain it was once made out to be.

Final Thoughts: The Bottom Line on Tallow

Beef tallow is not a trend without substance. It is a functional, ancestral fat with credible benefits when used appropriately. Whether you are searing a steak or moisturizing your skin, the key is in sourcing high-quality, clean tallow and using it as part of a diverse, whole-food lifestyle.

With its rich texture, high heat stability, and nutritional depth, Wagyu beef tallow deserves its place in modern kitchens. The hype has roots, but like all things, balance and quality matter.
