Description
1 study reviewed
In plain English

People can digest both plants and meat thanks to how their bodies evolved, but being able to eat meat doesn’t mean they have to eat a lot of it.

See the scientific wording

Human beings are constitutionally omnivorous, meaning they are biologically capable of digesting both plant and animal foods, but this adaptability implies dietary choice rather than requirement for high animal product intake.
