Preserve vision health
Leafy greens-in particular kale, dandelion, mustard greens and Swiss chard-are good sources of carotenoids lutein and zeaxanthin, which help filter high-energy light that may cause eye damage. Lutein and zeaxanthin reduce discomfort caused by glare, decrease the risk of cataracts and increase how far you can see.
Help fuel your body
A one-cup serving of raw escarole provides 1/10 of your daily needs for vitamin B5 (pantothenic acid). The B vitamins help convert the carbs in food to glucose that the body can use as a fuel to produce energy. B vitamins are water soluble, which means the body doesn’t store them, so you need to get enough each day.
Boost bone health
The slightly bitter taste of many leafy greens is a good sign: It reflects their high levels of calcium. It’s unlikely you’d be able to eat enough greens in one day to get the 1,000 mg of calcium recommended daily for women ages 31-50, but they can help you get there: A ½-cup serving of dandelion greens contains 78 mg calcium; mustard greens have 55 mg; Swiss chard has 54 mg; and kale has 49 mg.
