Protein Content of Food: Vegetables and Fruits

Vegetables, legumes and fruits are good sources of protein. Generally, legumes have higher content of protein than vegetables and fruits. The advantage of plant protein sources over animal protein is that plant protein sources are low in fat content and high in dietary fiber. Nonetheless, protein in plants (except soybean) is incomplete, meaning all the essenatial and non-essential amino acidsare not present in a single plant.

In the following table is protein content of foods. High protein foods are at the top and those with low protein content at the bottom.
