                                While animal proteins provide all nine essential amino acids, most plant proteins are considered 'incomplete' because they lack adequate levels of one or more essential amino acids. This makes it crucial for those on a plant-based diet to understand what are plant proteins deficient in to ensure a balanced nutritional intake.
