Yes, lettuce can be a healthy part of your eating plan. “People often underestimate the nutritional value of lettuce,” says registered dietitian Susan Campbell, RD, LD. “But as a leafy green, it’s just as good for you as kale or spinach.” And because you probably eat lettuce raw, you get most of its nutrients, as raw vegetables keep more nutrients than cooked ones.
Americans typically eat four main types of lettuce. Nutritional values vary depending on which leafy green you choose.
Campbell shares how lettuce can help keep you healthy.
Lettuce has been a healthy part of people’s meals since ancient times. Egyptians from thousands of years ago recognized the health benefits of lettuce and grew it in their gardens. Eating more of this green leafy veggie has several health benefits:
One cup of shredded lettuce leaves (any type) has approximately:
Nutrient-wise, a cup of lettuce (any type) has up to:
But it’s also important to know that not all lettuce is created equal. For instance, red and green leaf lettuce outshine iceberg lettuce in terms of nutrition, says Campbell. They can have six to 20 times more vitamin A, vitamin K and lutein. In general, “The darker colors of the lettuce make it more of a rock star,” Campbell adds.
Lettuce is chock-full of antioxidants. These food chemicals protect you against free radicals, which cause inflammation and may contribute to eye diseases, diabetes and other chronic conditions.

Lettuce is especially high in:
Research shows that eating a small side salad before your main course can help you feel fuller. As a result, you eat fewer calories during your meal. Findings suggest that starting your meal with a salad can lead to weight loss or help you maintain a healthy weight.
Most lettuce varieties are excellent sources of vitamin K. “Your body needs vitamin K to build strong bones and clot your blood,” says Campbell.
Vitamin K, along with lutein and folate (vitamin B9), may also help prevent memory loss. A 2018 study found that a daily serving of green leafy vegetables improved memory in people as they aged.
As much as 95% of lettuce’s weight comes from water. So, when you eat lettuce, you’re also quenching your thirst. And the high water content fills you up faster, helping curb hunger and prevent overeating.
Lettuce is a versatile vegetable that’s affordable and easy to add to dishes. “Lettuce is a great fat-free, low-calorie way to get more leafy greens into your meals,” notes Campbell.
