animal nutrition > plant nutrition. Gram for gram.
and there are essential nutrients in animals that you just cannot get, from plants.
1 cow can feed a whole person for a year.
The first two statements are bold claims to make I'd like to see some credible sources on this.
The last one which I'm also not sure is true one could put in context. E.g. as a comparison how much acres of land/ water/ energy does it use compared to vegetables.

Basically it's harder to achieve all essential amino acids in a plant based diet. Animal protein is also linked to lower stroke risk and diabetes, but can lead to higher heart disease. Overall it's not absurd to say animal protein is better than plant protein.
On the last comment: https://rainbowrunfarm.com/how-many-people-can-a-cow-feed/
This source claims one cow can feed one person for 8 years, but that feels a bit absurd so I did my own math. 80% lean beef contains 1152 calories per pound. Meaning at 2000 calories a day one person eats 1.74 pounds per day.
https://beef.unl.edu/beefwatch/2020/how-many-pounds-meat-can-we-expect-beef-animal
This source claims about 880ibs of useful meat is available on the average cow, meaning one person can survive for 505 days on one cow, or 1.38 years.
The third source claims one acre per cow raised is the land needed for grazing. Checking other sources this seems to be the general consensus on cattle to acre ratio.
https://permaculturism.com/how-much-land-does-it-take-to-feed-one-person/
This source claims you need 1.69 acres of land to raise all the required plants in order to feed yourself for one year. Therefore raising the cow and eating it would be a more viable space.
