A second Way of Proving that Human is Herbivore through Milk Composition

“we expect milk composition to vary in accordance with diet, with herbivorous species producing milk lower in concentrations of fat and protein, and lower energy density relative to omnivorous and carnivorous species.”

Human milk is 90% water, (cow’s milk is 87% water and sheep’s milk is 81% water).

Cow’s milk has 3.5 times more protein than human milk. Sheep’s milk has almost double the fat 6.9% of human milk. Therefore human milk is lower in fat (relative to sheep) and lower in protein (relative to cow) and higher in water (relative to sheep and cow). Therefore human milk has lower energy density than cow and sheep’s milk which proves that we are Herbivore.

The composition of milk is unique to each species. Human milk contains 9 g protein/l to be compared with 34 g/l in cow's milk and 120 g/l in rat's milk. The fat content is similar or about 38 g/l in human and cow's milk but as high as 150 g/l in rat's milk.

The fat content reported in human (3.64%) and cow’s milk (3.61%) was higher compared to mare’s milk (1.21%) [12]. In milk samples analyzed by Malacarne et al. (2002), sheep milk presented the highest fat content, reaching 6.9 ± 1% [12]. The fat content reported in goat milk was 4.2 ± 0.9% [13].
