1. Anti-Nutrients – Many vegetables contain compounds like oxalates, lectins, and phytates, which can inhibit mineral absorption and may contribute to inflammation or digestive distress.
2. Lack of Essential Nutrients – Unlike animal products, vegetables do not provide complete proteins, heme iron, or bioavailable essential vitamins like B12, making them unnecessary for survival.
3. Evolutionary Evidence – Humans evolved as apex predators, thriving on nutrient-dense animal foods. Many traditional societies, such as the Inuit and the Maasai, have thrived with little to no vegetable consumption.
If one can obtain all necessary nutrients from animal-based foods without the potential downsides of plant toxins, then vegetables become optional rather than essential.
