Common Questions About Kale

Is frozen kale just as good as fresh?

Fresh kale maybe intimidating at times, because its' large, curly, fibrous leaves can trap dirt, making it challenging to clean and cut. If you are not used to making it, you may not know what to do with it.

Instead, you can either purchase kale that has already been cleaned and cut (this is good to make kale chips or easy to use to saute or throw in soups, stews, or chili) or purchase frozen, chopped kale. Many times, buying frozen vegetables is just as good, if not better, than buying fresh because the vegetables are picked at their peak freshness which makes them retain more vitamins and minerals.

Which variety of kale is the healthiest?

Purple varieties contain anthocyanins too, which have been linked with improving heart health.

Note that some experts suggest steaming kale to maximize it's cholesterol lowering effects because the fiber-related components in kale do a better job of binding together with bile acids in your digestive tract when they've been steamed.

Picking and Storing Kale

Purchase kale, whole, frozen, or cleaned, chopped, and packaged. Look for kale that is crisp, with a grayish-green color. Avoid kale that is wilted or limp.

You can store kale in the coldest part of your refrigerator for a few days. To prevent wilting, place kale in a plastic bag first and close it loosely. If you are unable to use it in a few days, you can cook it—boil or steam, and place it back in the refrigerator cooked. Freeze it if you don't plan on using it for a while, it will keep in the freezer for about a month or two.

To wash fresh kale, place it in a bowl of cold water. Empty the bowl and repeat until all the dirt is cleared from the leaves.
