When it comes to the leafy greens you put in your salads, not all are created equal.

So which leaves and lettuces should you use in your salad to justify the croutons, bacon, and tasty dressing you add?

We’re here to help you find the most nutritious ones.

In the past rankings, we’ve relied on the CDC’s 2014 list of “powerhouse foods”. But this time, we factored in how many nutrients (specifically potassium, fiber, protein, riboflavin, niacin, folate, B6, calcium, iron, zinc, and vitamins A, C, and B6) the greens pack per calorie.

Iceberg lettuce has about only 7% of your daily vitamin A per cup, and only 3% of daily vitamin C — among the lowest on this list.

10. Radicchio

Radicchio is a member of the chicory family. It’s also packed with vitamin K, containing more than 100% of your daily value.

TIE – 8. Watercress

Watercress, with its little round leaves, was considered the top powerhouse food in the CDC study. However, by our metrics, it didn’t pack in as many nutrients as others on the list. It’s high in vitamins A, C, and K and incredibly low in calories.

It’s also linked to a lower risk of type-2 diabetes and is
