ISU Extension: Get your Green on St. Patty's with Kale
By Rachel Wall, ISU Extension Dietitian
Want to be trendy in 2014? Then eat more kale. This dark leafy green vegetable is considered to be a "nutritional powerhouse" and is high on the list of nutrition trends for the new year. All fruits and vegetables are healthy and provide a variety of vitamins, minerals and antioxidants, the compounds that protect cells from damage.
However, kale is marketed as one of the healthiest vegetables for humans. It's part of the Brassica family, which includes other cruciferous vegetables such as broccoli, cauliflower, cabbage and Brussels sprouts.
MyPlate recommends we eat 1 ½ cups to 2 cups of dark green vegetables each week
One cup of chopped kale provides:
o 684% of the daily value of Vitamin K
o 206% of the daily value of Vitamin A
o 134% of the daily value of Vitamin C
Kale's eye health and anticancer benefits are linked to its concentration of two antioxidants: carotenoids and flavonoids.
Vitamin K plays an important role in blood clotting, but also helps with bone health and acts as an antioxidant. Vitamin K has been shown to help lower the overall risk of getting or dying from cancer. However, the Vitamin K of kale can interfere with blood thinning medications, such as warfarin. Anyone taking a blood thinner should talk with his or her health care professional before eating kale. Despite its many health benefits, kale has oxalates, which can interfere with calcium absorption. So it's important to eat calcium-rich foods at different times than when eating kale.
Tips for Buying, Storing and Preparing Kale:
Kale is available throughout the year. Its peak time is from the middle of winter through the beginning of spring.
Look for kale with firm, deeply colored leaves and moist hardy stems.
The leaves should look fresh, be unwilted, and be free from signs of discoloration, such as yellowing. Choose kale with smaller-sized leaves. These are more tender and have a milder flavor than kale with large leaves.
To store, place kale in a plastic storage bag, removing as much of the air from the bag as possible. Store kale in the refrigerator; it will keep for five days. The longer it is stored, the more bitter its flavor becomes. Do not wash kale before storing, because exposure to water encourages spoilage. Before using, rinse kale leaves under warm running water.
Chop the leaves into 1/2" slices and the stems into 1/4" lengths for quick and even cooking.
