Broccoli vs. CauliflowerBroccoli and cauliflower are two vegetables that have a lot in common. They are both cruciferous vegetables and family members from the Brassica oleracea plant species. Both vegetables also originated from Europe’s Mediterranean region. Finally, they were likely both among the vegetables that you refused to eat as a kid—unless they were covered with cheddar cheese sauce, of course!


There’s no doubt that both veggies are healthy and packed full of nutrition. However, with all that similarity, it begs the question: what Brassica veggie is better for your health?

In this article:

Let’s compare the nutrients and health benefits to determine the winner of broccoli vs. cauliflower.

Nutrition Facts: Broccoli vs. Cauliflower

You should be eating at least five cups a week of cruciferous vegetables, especially including broccoli and cauliflower. Why should you eat these specific veggies? Well, the similarities between broccoli and cauliflower continue into their nutrient content.


Broccoli and cauliflower both contain vitamins A, C, and K; however, broccoli offers greater nutrient content in all three vitamins. Vitamins A and C are both essential for immune support.

A cup of broccoli contains 2,280.7 IU (international units) of vitamin A, which provides 46.6% of your recommended daily intake. It also contains 123.4 mg (milligrams) of vitamin C, or an incredible 205.7% of your recommended daily intake! Cauliflower only contains 54.9 mg of vitamin C and 21.08 IU of vitamin A.

What about vitamin K? Broccoli also outperforms cauliflower in this category. Broccoli contains 155.2 mcg (micrograms) of vitamin K compared to 11.2 mcg in cauliflower. The green cruciferous veggie also contains greater amounts of vitamin E and the B vitamins folate (B9), pyridoxine (B6), pantothenic acid (B5), niacin (B3), and riboflavin (B2).


Protein is essential for every cell in your body. The macronutrient is considered important for building and strengthening muscles, bones, skin, cartilage, and blood. Protein is also necessary for strong immunity and healthy brain function.

It is important to remember that not all protein sources are the same. For instance, your daily protein bar may be packed with protein, but it is also filled with sugar and food additives. Cruciferous vegetables like cauliflower and broccoli help contribute to your daily protein intake, but broccoli packs bigger muscle in the protein category as well. A cup of cooked broccoli (156 grams) contains 4.7 g of protein, while cauliflower contains 2.3 g of protein per cup (124 g).


Are you concerned about your calorie intake? The good news is that broccoli and cauliflower are both extremely low in calories; however, cauliflower has a slight edge in this category. A cooked cup of broccoli contains 44 calories, whereas cooked cauliflower contains only 29 calories per cup, which is good news for your waistline.

Broccoli and cauliflower also benefit any weight loss plan with about 0.55 g of total fat per cup. Overall, both veggies should help you lose weight.


Besides vitamins, the powerhouse cruciferous vegetables are also packed with the other important micronutrients—minerals. Both vegetables are high in calcium, iron, and magnesium.

Calcium is important for the maintenance and development of teeth and bones, and iron helps with your body’s energy production. Magnesium prevents calcium deposits and also acts as a muscle relaxant.

A cup of cooked broccoli is considered a better dietary source of all three minerals. Broccoli contains 74.7 mg of calcium, and cauliflower only has about 19.8 mg; broccoli has 1.4 mg of iron, whereas cauliflower provides 0.41 mg; and broccoli is a very good source of magnesium with 39.0 mg—about 10% of your daily value—while cauliflower only has 11.2 mg of magnesium.

Broccoli is also a better source of manganese, potassium, phosphorus, and zinc.

Health Benefits of Broccoli

It is clear that broccoli is a nutritional superfood, and scientific evidence supports its wide range of health benefits. For instance, broccoli has widely been regarded for cancer prevention based on epidemiological data and experimental testing.

Cancer Prevention

Broccoli contains the sulfur-containing compound sinigrin, which helps release special phytonutrients, like isothiocyanates, that detoxify cancer-causing carcinogens.

The vegetable also contains other cancer prevention properties. In particular, indole-3-carbinol, found in broccoli, helps deactivate the tumor promoter 4-hydroxyestrone, especially in breast cells. The phytonutrient glucoraphanin in broccoli is also known to convert to sulforaphane in your body; sulforaphane is helpful for liver detoxification, which quickly removes any potential carcinogens.

Heart Health

Broccoli also contains plenty of heart-healthy benefits. Broccoli’s sulforaphane also contains anti-inflammatory properties, which can help prevent and reverse blood vessel damage from inflammatory chronic blood sugar issues. Broccoli is loaded with other heart-healthy nutrients, such as omega-3 fatty acids, magnesium, potassium, folate, fiber, and vitamins B3, B6, and E. The soluble fiber in broccoli even helps reduce cholesterol levels in your body.

Eradication of Harmful H. Pylori Bacteria

What are broccoli’s other health benefits? The sulforaphane in broccoli and broccoli sprouts may help eradicate the bacterium Helicobacter pylori (H. pylori), which is responsible for many stomach ulcers and stomach cancer risk. In a study published in the journal Antimicrobial Agents and Chemotherapy in 2003, researchers found that sulforaphane eliminated H. pylori in eight of 11 infected mice. In another study published in the journal Cancer Prevention Research in 2009, researchers observed 48 H. pylori-infected patients for a two-month period. They were assigned randomly to eat 70 g daily of the sulforaphane-heavy broccoli sprouts or a placebo (alfalfa sprouts, which do not contain sulforaphane). The broccoli sprouts decreased biomarkers of H. pylori colonization, including H. pylori stool antigen and levels of urease. The broccoli sprouts also reduced biomarkers of stomach damage, including serum pepsinogens I and II.

Eye Health

Broccoli is also thought to benefit people with vision problems, such as cataracts. Broccoli contains two powerful antioxidants, lutein and zeaxanthin, which are from the carotenoid family. The sulforaphane in broccoli also may contain antioxidant properties, which helps protect the eye from potentially damaging free radicals.

Other Health Benefits

Broccoli is also important for bone health, osteoporosis prevention, and weight control. The alkalinizing vegetable also helps reduce acidity within your body.

What Are the Best Ways to Eat Broccoli?

You can eat it raw, but if you plan to cook broccoli, it is best to steam it lightly. Broccoli doesn’t taste good when overcooked. (Keep reading to find out some other tasty ways to enjoy this cruciferous vegetable.)

Health Benefits of Cauliflower

Now let’s take a look at cauliflower. Although broccoli contains more nutrients, there are still plenty of reasons to pile cauliflower on your plate. Here are some of its health benefits.

Cancer Prevention

Similar to broccoli, cauliflower contains glucosinolates and thiocyanates, such as sulforaphane, which can help liver enzymes eliminate carcinogens and prevent cancers, including ovarian cancer, prostate cancer, colon cancer, rectal cancer, lung cancer, endometrial cancer, stomach cancer, breast cancer, and bladder cancer.

In a review published in the journal Advances in Experimental Medicine and Biology in 1999, researchers observed six cohort studies and 74 case-control studies regarding the anti-cancer effects of Brassica vegetables, including Brussels sprouts, broccoli, kale, and cauliflower. In 64% of the case-control studies, there was an association between Brassica vegetable consumption and a lower cancer risk.

Heart Health

The cruciferous vegetable is also excellent for heart health. Cauliflower is a good source of folate and vitamin B6; these B vitamins are necessary for homocysteine metabolism, which can prevent issues associated with cardiovascular disease, such as arterial wall damage and high blood levels. Cauliflower also contains the omega-3 essential fatty acid, alpha-linolenic acid, which can reduce biomarkers for cardiovascular disease.

Cauliflower also contains the heart-healthy nutrients vitamin B3, vitamin C, magnesium, and potassium. The sulforaphane in cauliflower may also help reverse blood vessel damage. Finally, cauliflower also contains allicin, which is associated with the reduction of heart disease and stroke.


Cauliflower is important for digestion. The vegetable contains 2.28 g of fiber, which helps with digestive support. The sulforaphane in cauliflower also helps protect the stomach lining and prevents H. pylori overgrowth.

The glucosinolates and thiocyanates also display anti-inflammatory properties, which can reduce inflammation in health conditions likes ulcerative colitis, irritable bowel syndrome (IBS), inflammatory bowel disease, Crohn’s disease, rheumatoid arthritis, type 2 diabetes, insulin resistance, metabolic syndrome, and obesity.

The vitamin K and omeg-3 fatty acids in cauliflower help prevent chronic inflammatory conditions. The vegetable’s glucosinolates (gluconasturtiian, glucoraphanin, and glucobrassicin) also help activate and regulate enzyme activity during the liver detoxification process.

What Is the Best Way to Eat Cauliflower?

Lightly steaming cauliflower is always a good idea. Mashing cooked cauliflower can also turn it into a healthy alternative to mashed potatoes. It is an easy recipe, and only requires a large head of cauliflower, five garlic cloves, a third cup of chives and basil, and grey Celtic sea salt.

To make some nutritious cauliflower mash, first steam the cauliflower and garlic for about 15 minutes, or until tender. Next, combine the steamed cauliflower and garlic, sea salt, and fresh herbs in a high-powered blender or food processor until a mashed potato consistency forms. And that’s it: in two steps, you have a delicious side dish to any healthy meal.

Is Broccoli Better Than Cauliflower?

And the winner is…

The statistics don’t lie: broccoli is more nutritious than cauliflower. Broccoli outperforms cauliflower in every major nutritional category, especially for protein, fiber, calcium, iron, magnesium, and vitamins A, C, and K.

Where does cauliflower have the advantage? Cauliflower contains fewer calories.

Overall, you can’t go wrong with either cruciferous vegetable. After all, they are both loaded with nutrients, even if one is a seeming superfood and the other is just a healthy food choice.

Is There Any Downside to Their Health Benefits?

Both vegetables pose a common side effect: gas or bowel irritation. Like most vegetables, however, the health benefits of broccoli and cauliflower far outweigh the adverse effects.

One important note: broccoli is a higher source of vitamin K, which may interfere with blood-thinning drugs.

It is also important to remember that broccoli and cauliflower contain the lowest amounts of pesticide levels, according to the Environmental Working Group. This indicates that it is safer to buy conventional broccoli and cauliflower, though it is still wise to purchase organic whenever possible.
