The Health Benefits Of Lettuce

LETTUCE

Lettuce is a leafy vegetable, famous for giving salads their base. There are multiple types of lettuce, and they all share the scientific name Lactuca sativa.

The health benefits of lettuce come primarily from its vitamin content. Health benefits vary depending on the type of lettuce a person eats. All lettuces fall into one of four varieties:

  • Head lettuce (capitata)
  • Leaf lettuce (crispa)

  • Romaine lettuce (longifolia)
  • Celtuce lettuce (augustana)

Head lettuce gets its name from its round shape. This variety includes iceberg and butterhead lettuces, both of which are commonly sold in grocery stores. 

Leaf lettuces don't form a head, and are instead connected to a stem. Some of these lettuces are darker in color or have reddish leaves.

Romaine lettuce is another lettuce type commonly sold in grocery stores. It's also known as the main ingredient in Caesar salad.

Celtuce lettuce, also called asparagus lettuce or stem lettuce, has a distinctive, large stem. This lettuce variety is common in China, but less common in the Western world.

Health Benefits

The health benefits of lettuce vary across varieties of lettuce, based on their nutritional contents. Iceberg lettuce is generally the lettuce type with the lowest amount of nutrients.

Bone Strength

Lettuce is a source of vitamin K, which helps strengthen bones. Consuming adequate amounts of vitamin K can also reduce your risk of bone fracture.

Hydration

Water makes up over 95% of raw lettuce. As a result, eating lettuce hydrates the body. Although drinking liquids is necessary, water in foods can also significantly contribute to hydration.

Improved Vision

Lettuce is a source of vitamin A, which plays a role in eye health. Vitamin A can reduce a person's risk of cataracts. Vitamin A also helps prevent macular degeneration.

Improved Sleep

Extracts of multiple lettuce types have also been shown to promote sleep. Until further research is conducted, it's unknown if lettuce in its natural form can produce a similar effect.
