What Are Cruciferous Vegetables and What Are They Good For?

Cruciferous vegetables: health benefits and recipe uses.

Cruciferous vegetables include kale, Brussels sprouts, arugula, and so much more. Nutritious, anti-inflammatory, and possible aids in cancer prevention, cruciferous vegetables are a supergroup containing root vegetables, leafy greens, and even a few veggies that can provide both from one plant!

The word “cruciferous” comes from the Latin word cruciferae, meaning “cross bearing.” This is because it’s an informal name for the mustard family of plants, the leaves of which have four petals that resemble a cross. Like many green vegetables, a lot of cruciferous veggies contain high amounts of vitamin K, vitamin C, and folate. Rich in fiber and low in calories, cruciferous vegetables are a valuable part of an adult’s diet, which ideally should include 2 1/2 cups of vegetables per day.

Cruciferous vegetables also contain phytonutrients, plant-based compounds that can possibly help lower inflammation and reduce the risk of cancer (including prostate cancer and breast cancer).

With so many benefits, cruciferous veggies are a healthy eating requirement. So, let’s get into the crux of cruciferous vegetables.

Cruciferous Vegetables

Here you’ll find the roots, tubers, and buds of the cruciferous family.

Brussels Sprouts

Brussels sprouts grow on one long stem in small cabbage-like bud clusters.

  • Brussels sprouts are helpful in detoxification and contain cancer-fighting properties.

The Best Ways to Eat

  • Cut Brussels sprouts in half and toss/roast them with something sweet or salty—maple syrup if you wish, or some Parmesan cheese.
  • Slice and bake them into lightly salted veggie chips, or sear them in a pan with some olive oil.
  • Steam them whole and drizzle with lemon juice, or chop them up raw and use them in salads.


Cauliflower is a cabbage that grows a large head of small white flower buds. Each head can be cut into “steaks” or chopped down into florets.

  • Cauliflower is high in fiber, which is good for digestive support.
  • This white veggie has detoxifying phytonutrients and antioxidant benefits from vitamin C, and may help lower your risk of cancer.
  • Cauliflower is an excellent source for vitamin K and its anti-inflammatory benefits.

The Best Ways to Eat

  • Chop and stir-fry cauliflower as a rice replacement.
  • Roast the florets with olive oil and your preferred spices to serve as a side dish.

Also called “German turnip,” Kohlrabi is a non-starchy vegetable shaped like a bulb with green fronds and similar in look to fennel (though not in taste).

The Nutritional Benefits

  • Kohlrabi contains an abundant amount of vitamin C and other vitamins, as well as dietary fiber.
  • With only 27 calories per 100 grams, a minuscule amount of fat, and no cholesterol, kohlrabi is another healthy addition to any diet.
