While dark leafy green vegetables such as kale and spinach are touted as being the most nutritious, romaine lettuce can be a great addition to a balanced diet.
Romaine lettuce contains fiber, a non-digestible carbohydrate that contributes to digestive health and helps maintain blood sugar control. It also contains various nutrients that are important for health, such as calcium and vitamin K. Calcium and vitamin K are critical for maintaining strong, healthy bones, preventing bone mineral loss, and potential fractures.
Romaine lettuce is also a wonderful source of vitamin C and folate. Vitamin C is necessary for immune health, growth, and repair of body tissues, formation of collagen, absorption of iron, and is involved in wound healing. Folate, one of the B vitamins, is involved in creation of red blood cells, which carry oxygen around the body. Folate also contributes to generation of energy and production of DNA. While low in overall fat, romaine lettuce contains higher levels of important polyunsaturated fats than other types of lettuce. Romaine lettuce is also a good source of beta carotene, which converts to vitamin A in the body and is critical for eye health.
Despite public perception that romaine lettuce is not as nutritiously valuable as other darker lettuces, it can be a wonderfully nutritious choice to add to a balanced diet. This sturdy lettuce is packed with nutrients and can be added to salads, sandwiches, and smoothies. While spinach and kale are very nutritious lettuces, they are high in oxalates, which in high amounts can prevent absorption of certain minerals such as calcium. High oxalate content may also be an issue for those with compromised gut health. Romaine lettuce is lower in oxalates and so may be beneficial for sensitive individuals. Plus, Romaine is a low-calorie lettuce that naturally contains high levels of fiber, varying vitamins and minerals, carotenoids, and phenolic compounds that are important for overall health.
