Most animals have a fairly simple diet, carnivores eat only meat their whole life, cows eat exclusively grass etc. So why are human bodies so picky and need a balance of protein, fat, carbs etc from different sources to perform well?
In: Biology
Cows and other herbivores do not eat “just grass”. A natural pasture large enough will grow hundreds or thousands of different varieties of grasses, herbs and other plants that provide most of the nutrients (carbohydrates, proteins, fatty acids, vitamins, etc) that the animals need. Animals will also straight up eat dirt in small amounts to gain minerals. Every species of animal has their own digestive system (including microbiome) specialised on a diet that provides them with what they need. “Balanced” is different for different animals.
