Proteins

Proteins are the building blocks of a developing body. They are needed for muscle development and many important metabolic reactions in the body. Lettuce contains a good 20 per cent of proteins in its total quantity. Lettuce, scientifically known as Lactuca sativa, was first cultivated by the Egyptians thousands of years ago. The Egyptians used the seeds to produce oil and also utilized the leaves of this useful vegetable. The plant also had cultural and religious significance in ancient Egypt, as it was considered to be sacred. Later, the Greeks and Romans also cultivated this crop.
