Why You Need This Recipe

This anti-cancer smoothie recipe is similar to my Collard Green Smoothie recipe, but with the addition of frozen broccoli florets. Broccoli contains sulforaphane, the compound in broccoli that has been studied for its cancer-fighting properties.

In this recipe, you actually can’t taste the frozen broccoli once it’s blended with all of the other great ingredients in this recipe. The carrot juice, fruit, citrus, cocoa powder, mint leaves all work together to magically cover up the “green” flavor of the veggies.

Even if you don’t necessarily love the taste of green vegetables, I think that you will enjoy the flavor of this very healthy anti-cancer smoothie. Here’s a list from the MD Anderson Cancer Center of more cancer-fighting foods and here’s my list of the best greens for smoothies.

How Broccoli Fights Cancer

Studies show that there are compounds in cruciferous vegetables known as isothiocyanates that fight cancer. However, as far as we know, these compounds are only present in raw or very gently cooked cruciferous vegetables. So, that’s why this recipe uses gently blanched and frozen broccoli florets.

It’s also easier to hide the flavor of frozen broccoli as opposed to fresh broccoli. And, the frozen florets even help to thicken the smoothie.

Key Ingredients

Carrot juice is the base of this healthy green smoothie. It adds natural sweetness with no added sugar.

Frozen broccoli adds cancer-fighting compounds and add thickness to the smoothie.

Frozen banana and frozen strawberries add thickness and more natural sweetness.

Cocoa powder and fresh mint leaves help add flavor and cover any “green” flavor from the veggies.

Recipe Steps

Step One

The first step of this recipe is to gather up your ingredients.

This recipe is forgiving, so don’t worry if you don’t have every single one of the ingredients. For instance, if you don’t have carrot juice, you can use water (see my recipe for homemade carrot juice). If you don’t have fresh mint, you can just leave it out.

Combine all of the ingredients in the base of a high-speed blender like a Blendtec or a Vitamix. Blend on high for just about 45 seconds, or until the smoothie is thick and creamy.

Recipe FAQs

Can I use frozen broccoli florets that I buy at the store?

Most frozen vegetables you buy at the store are meant to be cooked before being consumed. So, it’s better to buy fresh broccoli, blanch it, and then freeze it yourself.

Can I leave out the banana in this recipe?

Yes, but the smoothie will not be as creamy. I would recommend substituting frozen mango for the banana.
