Health Benefits of Iceberg Lettuce

This lettuce has many health benefits, including weight loss, prevention of birth defects, and reduced risk of many diseases. Let us discuss these in detail:

Improved Health

It is rich in vitamin A, which is an essential vitamin required for healthy eyes as well as the growth and development of bones. It also strengthens the immune system.

Birth Defect Prevention

Iceberg lettuce is a good source of folate. Intake of folate-rich foods by pregnant women helps prevent birth defects such as spina bifida and anencephaly. [4]

Blood Clotting

Iceberg lettuce also contains vitamin K, which aids in the production of proteins required by the body for normal blood clotting. [5]

Weight Loss

Iceberg lettuce has high water content and it is very low in calories. Eating a lettuce salad will fill your stomach without adding to the total calorie count consumed per meal. Therefore, it encourages weight loss efforts. But do remember that while the leaves will not add the calories by themselves, the dressing might. So, keep it light if you are eating lettuce for weight loss.

Fights Diseases

Because of the folate content, iceberg lettuce may also help fight various health issues, such as folate deficiency, depression, and chronic diseases. [6]

Select & Store

Always select lettuce that is fresh and has crisp leaves. Avoid buying the ones that are slimy or wilted. Wash well before use to avoid any foodborne illness and store it in a cool place. To ensure that the lettuce stays fresh longer, wrap up the lettuce head in a kitchen towel and then put it in a ziplock bag. This way it will stay fresh for at least five days in your refrigerator.

Quick Ways to Serve

The lettuce can be used in various recipes like the following:

  • In salads with fruit, vegetable, chicken or seafood
  • In sandwiches and burgers
  • In soup or stir-fries
