Don’t just follow the trend; educate yourself. It’s time you find out exactly why and how you can introduce this super-healthy whole food into your diet.
What is Kale?
A member of the cruciferous vegetable family, kale is a relative of broccoli, cabbage, and many other healthy green leaf vegetables.1 There are a few varieties of kale including curly kale, ornamental kale, and Tuscan or Lacinato kale known as “dinosaur” kale, each offering a slightly different taste and texture. The most common variety is curly kale, available in domestic grocery stores, recognized for its ruffled hardy leaves, and sharp peppery taste.2
Curly kale served an important role during ancient Roman times as a staple food for peasants and it is said that kale was brought to the United States by English settlers in the 17th century². However, both ornamental and dinosaur kale are more recent variations, and didn’t make their debuts until the 19th or 20th centuries.
Kale Health Benefits
Kale contains many important vitamins and minerals including3:

This nutrient panel provided by kale has been linked to specific health benefits:
- Kale can help reduce oxidative stress and inflammation
The high levels of antioxidants found in kale have been linked to reduced oxidative stress and chronic inflammation associated with cancer preventative benefits. Carotenoids such as lutein and beta-carotene, and flavonoids including kaempferol, quercetin seem to play a significant role in these cancer-fighting mechanisms.
- Kale can support the body’s detoxification processes
Phytochemical isothiocyanates (ITCs) metabolized from glucosinolates found in kale, and high levels of sulfur compounds found in kale, help regulate and support detoxification at the cellular level. This cellular detoxification helps the body combat both dietary and environmental toxins.
- Kale can help lower cholesterol
Fiber-related components found in kale bind together with bile acids in the digestive tract and are excreted, thereby lowering cholesterol levels.
Buying & Storing Kale:
Look for kale in the cooled produce section of your local grocery store or health food market. It is recommended that you buy kale that is grown organically, as kale has become one of the newest members of the “Dirty Dozen,” a list of the most contaminated foods.
The leaves should be firm and deeply colored with stems that are moist and strong. Make sure that the leaves are not browning or yellowing, and they are free from small holes. If the raw leaves show signs of wilting, it is an indication that the greens have been sitting on the shelf for too long, or they were not properly stored…avoid these wilting leaves that alter the taste of the vegetable and can introduce unwanted toxins into your body.4
To store, keep kale refrigerated in an airtight bag. It can typically be stored for up to 5 days, but you may notice the flavor increase in bitterness with longer storage. Only wash the kale when you are ready to use it as washing before storage will promote spoilage.
