Romaine lettuce is a type of lettuce that is popular throughout the world. It differs from other kinds of lettuce in that it is tolerant to heat, making it suitable for growing in hot climates. It is thought that it was originally introduced from the island of Cos in Greece, which is how the lettuce acquired the British name of Cos lettuce.
Romaine lettuce is popular in salads and it is usually the choice of lettuce in Caesar salads. It is also used in cooking and in some traditions.
As with other types of lettuce, romaine lettuce is a good source of nutrition, albeit with some differences. This article looks at 10 benefits of romaine lettuce.
Romaine Lettuce Benefit #1: Complete Proteins
Our bodies are made up largely of building blocks that we know as proteins. There are different types of proteins and those found in vegetables are generally different from those found in animals. The best types are complete proteins as these contain all nine of the amino acids that are essential for our body.
Most proteins found in vegetables are incomplete proteins only, meaning that we would still have to supplement our diets with meat. Around 20% of the calories in romaine lettuce are proteins, many of which are complete. This can help vegetarians and vegans to get the nutrition that they need, but it is still important to make sure that all our nutritional needs are accounted for.
