Healthiest Salad Greens

1. Spinach

Look: Spinach leaves tend to be narrow to round leaves with no protrusions. They are dark, tender and soft to the touch.

Taste: Often the exclusive foundation of a salad, spinach is hearty with a bitter finish.

Nurition Factor: Spinach is a great source of the eye supporting antioxidant, lutein. It is one of the healthiest salad greens. Its also high in iron, calcium, vitamin K, vitamin A, Vitamin C and B vitamins. Although spinach packs more iron per gram than beef, it also contains oxalates. Oxalates can bind to both calcium and iron, compromising absorption. To maximize absorption of these minerals, try a citrus-based dressing. Vitamin C can boost iron absorption.

Fun Fact: The Florence, Italy-born wife of King Henry II of France, Queen Catherine de’ Medici, loved spinach so much that she insisted it be served at every meal. To this day, her love of spinach is the reason we call recipes that are dressed with spinach “Florentine.”

2. Romaine

Look: Romaine heads are tall with long leaves. They have a firm rib in the center. They tend to be lighter and more firm at the base and darker more loosely packed toward the tip. Romaine comes in both green and red varieties. It is one of the only common salad greens that can accurately be called “lettuce.”

Taste: Romaine leaves are very mild. They have an increasingly bitter taste closer to the rib.

Nurition Factor: This crunchy green a very hydrating leaf. It is a great source of vitamin A, vitamin C and folate.

Fun Fact: As you probably know, the romaine leaf is the only green used in Caesar salads. But what you might not know is that the Caesar salad was invented in the U.S. by restaurant owner Caesar Cardini. In 1924, a Fourth of July rush depleted his kitchen of most ingredients. In a moment of desperation, Caesar sprung into action creating a salad with the ingredients he had left: Romaine, olive oil, garlic, vinegar, Worcestershire sauce, lemon juice, egg, Parmesan and croutons.

3. Arugula

Look: Fast becoming a salad staple, the arugula leaves are long and skinny. They are darker in color and have 2-3 side projections.

Fun Fact: Arugula also grows tiny flowers which are often used as edible garnishes on salads.

4. Frisée

Look: Also known as “curly endive,” Frisée’s leaves are skinny and curly with colors that range from light yellow to yellow green. (I always remembered the name of this leaf by recalling that they look frazzled– “frazzeled frisée”).

Taste: This green is mildly bitter and nutty with notes of pepper.

Nutrition Factor: These leaves are a great source of vitamin C and fiber.

Fun Fact: Did your salad seem huge but you’re still hungry? Frisée is often used by restaurants to add volume and dimension to salads. It makes salads look bigger than they really are.

Taste: Belgium endive is mildly bitter with the more mild tastes coming from the lighter end of the leaf.

Nutrition Factor: Endive is an excellent source of beta carotene, B vitamins and fiber.

Fun Fact: In his 1617 publication of The Surgeon’s Mate, John Woodall recommended watercress as a potential remedy for scurvy.

7. Butterhead Lettuce

Look: Another of the true “luttuces,” butterhead lettuce is actually an umbrella term used to describe Boston, Bibb, Buttercrunch and Tom Thumb. Due to their delicacy, you’ll typically find these leaves packed in plastic containers. Butterhead lettuce heads are loosely packed with small, round and soft leaves. They range from pale green to dark green in color.

Taste: These leaves are very mild and smooth (like butter). Sometimes, they are even a little on the sweeter side.

Nutrition Factor: All varieties of butterhead lettuce are high in vitamin K. They are also very hydrating. They usually average about 96% water (how cleansing!).

Look: The final “lettuce” on this list is crisphead lettuce, also known as iceberg. It is larger in size with tightly packed leaves that are light pale green in color.
