Kale Nutrition Facts

Gone are the days when greens, mainly kale, collard and Swiss chard, were salted and stewed beyond recognition. Today kale is the sexy new salad staple that’s prominently featured in trendy restaurant menus from Melrose Avenue to Rodeo Drive—and for good reason. Kale is one of those super foods that’s good for just about every part of your body. Kale is a highly nutritious vegetable with powerful antioxidant properties and is considered to have anti-inflammatory properties, too. Kale is very high in beta-carotene, vitamin K, vitamin C, lutein, zeaxanthin and reasonably rich in calcium. (Note: Because of its high vitamin K content, patients taking anti-coagulants such as Warfarin are encouraged to avoid this food because it increases the vitamin K concentration in the blood, which is what the drugs are often attempting to lower.)

Kale, as with broccoli and other brassicas (cruciferous), contains sulforaphane (particularly when chopped or minced), a chemical believed to have potent anti-cancer/anti-inflammatory properties. Sulforaphane, which is formed when cruciferates are chopped or chewed, triggers the liver to produce enzymes that detoxify cancer-causing chemicals, inhibits chemically induced breast cancers in animal studies and induces colon cancer cells to go bye-bye.

Types of Kale

There are three types of kale: Curly, Black and Russian.

Curly Kale: Curly is the most common variety of kale that you can find in most supermarkets. Curly kale has large broad leaves with kinked and curly edges. It ranges in color from a light green to a dark purple, though dark green is the most common color. (Colored curly kale leaves are typically used as garnishes.)

Black Kale: Also known as Tuscan, this kale (my favorite) has oblong shaped, deep green bubbly leaves.  This variety hails from Italy and grows in tall, long stalks.  Choose leaves that are less than 18 inches because longer leaves tend to be bitter.

Red or Russian Kale: These kale leaves resemble oak leaves, because of their soft sage color and red veins. Russian kale is milder and sweeter in flavor than the other two varieties. When cooked, the green and red coloring in its leaves intensifies, creating a dramatic deep red and vibrant green color palette.

How to Buy, Store and Use Kale

How to buy: Choose leaves that are firm, not wilted, and are deeply colored with stems that are moist and strong. Make sure the leaves have no brown or yellow spots, and make sure they are free from small holes.

How to store: First wrap the kale in a paper towel. Then, place it in an airtight bag in the refrigerator. Kale typically stores well for up to one week. (A chef taught me to wrap it in paper towel. It’s amazing how it will keep the leaves fresh and perky!)

How to use: Only wash the kale when you are ready to use it, as washing before storage will make the leaves spoil faster. (Cooking note: As I prefer my kale slightly crunchy, I hold off on putting kale into soups or any other cooked recipe until the end. This will also help maintain its bright green color.)
