In the vast tapestry of life on Earth, humans hold a unique position. But when it comes to our diet, are we truly omnivores, as we've been taught? Or does an animal-based approach align more closely with our evolutionary history and physiological needs?
The Hunters: For millennia, our ancestors thrived as skilled hunters, securing nutrient-dense animal foods that fueled our growth, development, and eventual rise to dominance. This reliance on animal protein and fat was instrumental in shaping our brains, bodies, and social structures.
Physiological Evidence: Our bodies bear the hallmarks of carnivorous evolution. Sharp canine teeth for tearing flesh, short digestive tracts optimized for absorbing animal nutrients, and a high stomach acidity to break down protein all point to a diet designed for animal consumption.
From our sharp canine teeth to our short digestive tracts, many aspects of our anatomy suggest a natural inclination towards animal-based foods.
Animal foods provide a concentrated source of essential nutrients like vitamins B12 and D, iron, zinc, and omega-3 fatty acids – nutrients often lacking in plant-based diets.
The nutrients in animal foods are more readily absorbed and utilized by our bodies compared to those in plant foods.
Animal protein and fat promote a feeling of fullness, helping to regulate appetite and prevent overeating.
In certain environments, animal-based diets can be more sustainable than plant-based diets, particularly when utilizing regenerative agriculture practices.
The idea that humans are natural omnivores is often based on our ability to consume both plant and animal foods. However, our ability to do something doesn't necessarily mean it's optimal for our health and well-being. /n An animal-based approach challenges the conventional wisdom, suggesting that a diet focused on nutrient-dense animal foods may be more aligned with our evolutionary history and physiological needs.
Emerging research suggests that an animal-based diet may offer specific health benefits:
Some individuals with autoimmune diseases report reduced inflammation, symptom improvement and total remission on an animal-based diet, potentially due to the elimination of potentially inflammatory chemicals and plant compounds.
Animal-based diets, particularly those low in carbohydrates, may help improve insulin sensitivity and blood sugar control, which can be beneficial for individuals with diabetes or metabolic syndrome. This is due in part to the fact that animal fats play a crucial role in hormone production.
Dietary fat is essential for the production and regulation of hormones, the chemical messengers that control virtually every bodily function. Cholesterol, a type of fat found only in animal foods, is a precursor to many vital hormones, including:
Testosterone, estrogen, and progesterone, essential for reproduction, bone health, and mood regulation.
Cortisol, which helps the body respond to stress and regulate blood sugar levels.
Thyroxine and triiodothyronine, which regulate metabolism, energy production, and body temperature.
Maintaining a healthy balance of hormones is crucial for optimal metabolic function, fertility, energy levels, mood, and overall well-being. An animal-based diet, rich in the fats necessary for hormone production, may support this balance.
Some proponents of animal-based diets report improvements in mood and cognitive function, although more research is needed in this area.
