We’ve skipped the iceberg lettuce and show you some nutrient packed leafy greens that are packed with nutrients, and add texture and flavor to any salad. The following make great salad greens, but you can also cook these greens to add to various dishes or briefly sauté or wilt them before adding to salads.

Fresh greens are crisp, unwilted, vibrant in color and definitely not slimy or browning. As a general rule place greens in a plastic bag and put in crisper drawer in the refrigerator for up to 4 days. Wash thoroughly just before ready to use. Bunches of greens are often especially sandy may require several rinses.

Taste: peppery, slightly bitter

This slightly bitter and peppery green contains a chock-full of nitrate – over 250mg/100g! This natural form of nitrate has amazing health properties. Dietary nitrate protects the cardiovascular system by regulating blood flow and normalizing blood pressure1. Also, when absorbed dietary nitrate is converted to nitrite which our body reduces to nitric oxide in the stomach. This nitric oxide inhibits inflammation and platelet aggregation thereby reducing the risks of atherogenesis2.

Get the most out of your leafy green: If you’re not going to consume the arugula immediately after purchase, wrap it loosely in a thin kitchen towel and keep in an airtight container.

Taste: sweet, mild

A type of head lettuce, this tender lettuce has a smooth texture and its most well know varieties are ‘Bibb’ or ‘Boston lettuce’, which are rich in lutein and zeaxanthin (1223µg/100g) 1. Research suggests that these two antioxidant carotenoids reduce the risks of malignant melanoma, the most severe type of skin cancer, by protecting the skin against UV radiation3, as well as filter light’s high-energy blue and blue-green wavelengths from the visible-light spectrum – in doing so, lutein and zeaxanthin help prevent cell damage in the eyes4.

How to buy: Look for butter lettuce with fairly large, loose heads with thick leaves and even green coloring.

How to eat: It’s subtle taste and crisp leaves means that Butterhead lettuce lends itself to countless uses. Butterhead lettuce makes for a wonderful salad.

Don’t like the sight of dandelions on your lawn? You’re right – they should be in your plate. This wild green is rich in luteolin, an antioxidant flavonoid which could help delay and even prevent memory loss. According to a lab study, luteolin can reduce inflammation in the brain of aged rodents. The most interesting finding is that this effect appears to restore memory to levels observed in younger mice10.

How to buy:  Available in both red and green varieties, dandelion greens are delicious mixed with other greens in a salad.

How to eat: Because of their strong taste, they pair well with rich flavors such as bacon, goats cheese, egg yolk. Young dandelion leaves are delicious in salads. Larger greens taste best when they’re cooked. Chop leaves and add to soups, stews, or a crockpot dish. Finely chop leaves and steep in hot water for 10 minutes, then drain for a cup of fresh dandelion leaf tea. Add to salads in place of arugula.
