There are different kinds of proteins build from different amino acids, 9 of 20 amino acids are essential, meaning our bodies can not produce them, so we need to eat them.
Meat contains all the amino acids we need in our bodies in the amount we need in our bodies. For vegetables that’s not necessarily the case.
Because of that vegetable protein needs to be very varied and balanced to be a complete diet, and just lettuce and apples is not enough.
In a first world country we can get these vegetable proteins varied and year round with little to no problem, which makes vegan diet a sustainable and morally superior diet.
In the developing world people are generally happy about being able to have a complete diet, moral questions take a backseat to survival and health, so carnivorous or piscivorous diets are far more common.
