The concept of "nose-to-tail" eating is far from new, but it has gained renewed interest among those following Keto, Paleo, and Carnivore diets. This approach not only minimizes waste but also offers a plethora of nutrients that are often overlooked. In this article, we'll delve into the nutritional benefits of nose-to-tail eating, including the consumption of eggs, and why some nutrients are exclusively found in animal sources.

What is Nose-to-Tail Eating?

Nose-to-tail eating is the practice of consuming the entire animal, from its nose to its tail, including organs, bones, and everything in between. This approach is rooted in traditional diets and aims to maximize nutrient intake while minimizing waste.

A Nutritional Goldmine

When you eat nose-to-tail, you're not just getting protein; you're also getting a wide range of vitamins, minerals, and other bioactive compounds. Here's a breakdown:

  • Muscle Meat: Rich in protein, B vitamins, and essential amino acids.

  • Liver: A powerhouse of vitamin A, iron, and copper.

  • Kidneys: High in selenium and B12.

  • Heart: Packed with CoQ10, an essential nutrient for cellular energy.

  • Bone Marrow: Rich in healthy fats and collagen.

  • Eggs: Contain choline, biotin, and high-quality protein.

Nutrients Exclusive to Animal Sources

One of the most compelling arguments for nose-to-tail eating is the range of nutrients that are either exclusively found in animal sources or are more bioavailable when consumed from them. Here's a deeper dive into some of these essential nutrients:

  • Vitamin B12: This nutrient is crucial for the formation of red blood cells, neurological function, and DNA synthesis. Vitamin B12 is only naturally found in significant amounts in animal foods. Deficiency can lead to anemia and neurological issues.

  • Heme Iron: While plant foods contain non-heme iron, heme iron from animal sources is more readily absorbed by the body. This form of iron is crucial for oxygen transport and energy production.

  • Retinol (Active Vitamin A): While plants contain beta-carotene, a precursor to vitamin A, the active form known as retinol is only found in animal sources like liver. Retinol is essential for vision, immune function, and skin health.

  • Omega-3 Fatty Acids (EPA & DHA): While plants contain a form of omega-3 fatty acid (ALA), the most beneficial types—EPA and DHA—are found in fatty fish like salmon and sardines, as well as in grass-fed meat. These fatty acids are crucial for brain health, inflammation control, and cellular function.

  • Coenzyme Q10 (CoQ10): Found in large amounts in the heart, CoQ10 is essential for energy production at the cellular level. While it can be synthesized in small amounts by the human body, dietary sources from animals are more efficient.

  • Taurine: This amino sulfonic acid is found in animal tissues and is essential for cardiovascular function, development and function of skeletal muscle, and vision. It's not found in plant foods.

  • Conjugated Linoleic Acid (CLA): Found in the meat and dairy of ruminants like cows and sheep, CLA has been shown to have various health benefits, including anti-cancer properties and improved body composition.

  • Cholesterol: While often vilified, cholesterol is essential for the formation of cell membranes and the synthesis of hormones. Dietary cholesterol is only found in animal products, and emerging research suggests it may not be as harmful as once thought, especially in the context of a balanced, nutrient-dense diet.

By embracing a nose-to-tail approach, you're not just getting a wider range of nutrients; you're also getting them in forms that are more readily absorbed and utilized by the human body.

The Role of Eggs

Eggs are often considered "nature's multivitamin" due to their nutrient density. They are rich in:

  • Choline: Essential for brain health.

  • Biotin: Important for skin and hair.

  • High-Quality Protein: Contains all essential amino acids in the right ratios.

Sustainability and Ethical Considerations

Nose-to-tail eating is not just nutritionally beneficial; it's also a more ethical and sustainable way to consume meat. By using the entire animal, we honor its life and reduce waste.


Eating nose-to-tail offers a holistic approach to nutrition, providing all essential nutrients, including those only available in animal sources. It's a practice that pays homage to traditional diets, maximizes nutrient intake, and minimizes waste. So the next time you're at the butcher, maybe give that liver or those kidneys a second look.
