KNOXVILLE, Tenn. (WVLT) -- It's green stalks look rough and it might taste bitter.
To Dr. Pete Sulack, it's the king of the greens.
"Kale is more than just for health freaks, kale is for all of us," said Dr. Pete, America's Leading Stress Expert. "You're getting a ton of nutrients, you're detoxifying the body, you're helping your body deal with stress, and it can help you lose weight."
Kale is part of the cabbage family. According to an article in Self Magazine, it's been around for ages, but started getting popular about 15 years ago. Dr. Pete added it should stay.
He said the leafy green plant is power packed with nutrients and antioxidants, like vitamin A, C, and K.
"It has more vitamin C than a whole orange does," said Dr. Pete.
He called it one of the most nutrient-dense foods on the planet.
"It means you're getting the biggest bang for your buck," said Dr. Pete. "You're getting the most nutrients for a minimal amount of calories."
You can't just buy any kale. Dr. Pete told Local 8 News this is one of those foods you must buy organic.
"It's one of the foods that has more insecticides and pesticides than almost any other food, so I want to make sure I'm reducing toxins," said Dr. Pete.
If you don't like the bitter taste of raw kale, that's no problem.
You can stick it in your smoothies, drizzle it with some balsamic vinaigrette and saute it, or even make kale chips.
A small amount will fill you up without the extra calories. Dr. Pete suggested eating one cup three times a week.
