Plant proteins are considered “healthier”, as they do not contain unhealthy fats like beef or pork. But plant proteins are also incomplete- where animal protein contains all essential amino acids, plant proteins usually lack one.

These are considered good facts, and evidence exists that they can be helpful in preventing sudden death or heart failure in people with a history of cardiovascular diseases.

(7) There is no reliable plant protein that contains vitamin B12, which is a crucial vitamin for our bodies. Vitamin B12 helps in fatty acid and amino acid metabolism, DNA synthesis, maturation of red blood cells and functioning of the nervous system. Non-vegetarians can easily get vitamin B12 from animal proteins. (8)
