Mustard greens and kale help lower cholesterol. Here’s how: The liver uses cholesterol to make bile acids, which aid in fat digestion. When bile acid binds with the fibre of these greens, it gets excreted from the body-which means the liver has to use up more cholesterol to make new bile acid and, voilà, cholesterol levels are reduced. According to a U.S. study in Nutrition Research, steamed mustard greens and kale do this to a greater extent than raw.
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.
