On the other hand, plants tend to contain low amounts of at least one or two essential amino acids, depending on the category to which they belong. For example, legumes and veggies tend to be low in methionine and cysteine, while grains, nuts, and seeds tend to be low in lysine 2.

In practical terms, this means that following a diet providing too little of either food group may cause you to get insufficient amounts of essential amino acids.
