The Tale of Kale

hands holding kale Kale (Brassica oleracea) is a green leafy plant similar to broccoli, Brussels sprouts, and cabbage recently toted as a “superfood” for its health benefits. Super or not, kale provides essential nutrients such as vitamins A, C, and K, along with potassium, magnesium, calcium, sulfur, omega-3 and omega-6 fatty acids, and dietary fiber.

Despite the recent hype, kale has been around since the 40’s when is was promoted for the its hardy nature making it easy to grow and the nutrients it supplies making up for an otherwise stunted wartime diet. Once World War II ended and rationing was no longer an issue, many families strayed away from kale due to its taste, texture, and association with the war. In the decades since, kale varieties have changed to make it more taste bud friendly and many new recipes have been discovered making it possible to sneak kale into the diets of even the pickiest eaters. In the grocery store, look for kale that’s firm and has dark green or purple leaves for the best taste.

Like many things, no matter how healthy and nutritious kale is there is a possibility of consuming too much of it and negatively affecting your body. Eating a lot of kale, like most leafy vegetables, is likely to cause bloating, gas, and constipation. Also like many vegetables, there is a risk of pesticide ingestion with kale, so look for organically grown varieties if possible and make sure to thoroughly wash whatever you buy.
