Chickens are natural omnivores, and an all-vegetarian diet can cause nutrient deficiencies, often addressed by adding synthetic supplements. This is one of many reasons why the label "vegetarian-fed" is not a reliable indicator of superior health or ethical treatment for the chicken.

According to agricultural data, the use of meat and bone meal in animal feed significantly decreased after outbreaks of Bovine Spongiform Encephalopathy (BSE), leading to the rise of 'vegetarian fed' labeling. But what is vegetarian fed mean, and what does it actually reveal about the animals' diet and living conditions?

Over 95% of all animal species are invertebrates, and they, like all other animals, cannot produce their own food. This fundamental characteristic means that animals must consume other organisms to obtain the energy and nutrients necessary for survival, growth, and reproduction.

Almost all animals are heterotrophs, meaning they cannot produce their own food and must obtain energy by consuming other organisms. This fundamental characteristic leads to a wide range of feeding strategies, so determining which method of nutrition is found in animals depends on the species and its specific ecological role.

Globally, all animals are classified as heterotrophs because they cannot produce their own food and must obtain energy by consuming organic matter from other organisms. This fundamental biological process, known as heterotrophic nutrition, is the cornerstone of how the animal kingdom sustains itself, leading to a remarkable diversity of feeding strategies and adaptations.

Over the last 10,000 years, the human diet has changed more dramatically than at any other point in our evolutionary history, transitioning from a diverse, foraged diet to one dominated by agriculture and processed foods. This rapid shift raises questions about what we are truly 'designed' to eat.

While some proponents claim health benefits from a carnivore diet, the vast majority of scientific and evolutionary evidence points to humans being opportunistic omnivores. This highly restrictive eating pattern, which excludes all plant-based foods, raises significant questions about its nutritional completeness and long-term health implications.

Over 76 million cases of foodborne diseases are diagnosed annually in the United States, with a significant portion resulting from improperly handled foods like raw meat. This highlights the critical difference between the biological ability to digest raw meat and the actual safety of doing so for human beings, particularly in modern food systems.

For over three million years, human ancestors have consumed meat, fundamentally shaping our evolution and biological development. This deep history with animal-based foods helps explain what is the main purpose of meat, which is primarily to provide a dense, highly bioavailable source of key nutrients crucial for growth, brain development, and metabolic function.

Meat typically leaves the stomach in 2–3 hours and is fully processed in 4–6 hours, contrary to the myth that it rots in the gut. Our sophisticated digestive system is perfectly capable of breaking down meat, proving that humans can fully digest meat with high efficiency.
