The carbohydrates in that cup of lettuce are a half gram of sugar and less than a half gram of dietary fiber. Lettuce contains a trace amount of saturated fat, no cholesterol, and 1% of your daily recommended amount of protein.

What lettuce lacks in protein, it makes up for in vitamins, minerals, and antioxidants. And some varieties of lettuce have more fiber than others; fiber plays a role in healthy weight loss and lower blood pressure. Here are some of the compounds in lettuce:

Vitamin K: Vitamin K contributes to heart, bone, and blood health. One cup of lettuce has between 20% (iceberg) and 117% (red leaf varieties) of your recommended daily intake of vitamin K, depending on the variety.

Vitamin C: The vitamin C in lettuce is an antioxidant necessary for immune system and skin health. The greener the lettuce, the more vitamin C it contains.

Vitamin A: Vitamin A works as a powerful antioxidant necessary for immune system, eye, and skin health.

Diosmin: This antioxidant helps improve muscle tone and reduce inflammation in blood vessels.

Folate (Vitamin B9): This is important for normal tissue growth and cell function and is fundamental for pregnant women and older adults.

Flavonoids: These dietary compounds work as antioxidants to defend the body against damage from free radicals.

Potassium: This mineral is involved in many essential body functions, such as regulating blood pressure by reducing the effects of salt in your diet.
