Minerals, vitamins, and medicinal properties of cauliflower

Cauliflower is a good source of many vitamins and minerals. It is naturally gluten-free, making it the best option in all respects for gluten-intolerant people.

Cauliflower is a keto-friendly vegetable

People on a low-carb diet often turn to cauliflower because it is low in carbohydrates but high in nutrients. Gluten-free dieters will be pleased to discover cauliflower rice and cauliflower flour, a gluten-free, low-carb alternative to wheat and other grains.


Adults need 28–34 g of fiber per day. Adding vegetables and other fiber-rich foods is a roundabout way to ensure you are getting enough of this important nutrient.

Dietary fiber improves digestive health, reducing the risk of:

  • Heart disease
  • Stroke
  • High blood pressure
  • Some stomach problems
  • Obesity
  • Type 2 diabetes
  • Certain cancers

Only about 5% of people meet their recommended daily intakes, so eating cauliflower could be a way to reach your goal.

Cauliflower antioxidants

Vegetables in the Brassica family, like cauliflower, are good antioxidants. Antioxidants are important because they protect your body from free radical damage, which is caused by your exposure to cell-damaging chemicals.

Researchers have found that the non-edible parts of cauliflower, like the leaves, are high in antioxidants, suggesting they could be useful in the development of new food-related products.


Choline is a hormone that helps your metabolism. As for vegetables, cauliflower is one of the best sources of choline.

Choline is good for the following:

  • Memory
  • Mood
  • Use of muscles
  • Function of the brain and nervous system

The recommended intake for adults is 425–550 mg per day. It may sound like a lot, but many foods contain a lot of choline. For example, one hard-boiled potato contains 147 mg.

 What vitamins do cauliflower have?

Cauliflower is naturally rich in vitamins C and K. Adults should get 75–90 mg of vitamin C and 90–120 mcg of vitamin K daily. Cauliflower packs a punch with 51 mg of vitamin C and 16 mcg of vitamin K.

Vitamin C is a water-soluble vitamin, which means it doesn’t get stored in your body, and you have to get enough of it through food every day. This nutrient is good for the skin, especially for wound healing, and plays a role in the immune system.

Vitamin K is a fat-soluble vitamin. That means your body can store it. Vitamin K is essential for blood clotting and bone metabolism.

Cauliflower minerals

Cauliflower is rich in minerals, e.g.

  • Calcium: Vegetables, especially leafy greens like kale, are good sources of calcium. At 23 grams of calcium per cup, cauliflower packs the same punch as half a cup of fresh kale.
  • Magnesium helps regulate muscle and nerve function, regulate blood glucose, and regulate blood pressure. It compares to 16 mg per cup of broccoli. Adults need 310–420 mg per day.
  • Phosphorus is found in bones, teeth, DNA, and RNA. Adults need 700–1,250 mg per day. Cauliflower is one of the best vegetable sources of this essential mineral.
  • Potassium is required for normal cell function, fluid, and plasma levels. Most people probably think of bananas when they think of potassium because they are very high in the mineral. A medium banana has 422 mg of potassium, and 1 cup of cauliflower has 320 mg.

What happens when you eat cauliflower?

Research has shown that eating cruciferous vegetables, including cauliflower, can prevent cancer in the following ways:

  • Protecting cells from DNA damage
  • Avoid carcinogens
  • It shows antibacterial and antibacterial properties.
  • Causes cell death in damaged cells
  • Prevents tumor cell metastasis

Side Effects

While cauliflower benefits most people, some may experience side effects from eating too much of this vegetable. Cauliflower is known to cause gas, so if you experience stomach issues like irritable bowel syndrome (IBS), you may want to eat a small amount of cauliflower to see if it bothers you.

If you are taking blood thinners such as warfarin, there is conflicting evidence that dietary vitamin K may interfere with the drug. However, researchers say there is insufficient evidence to recommend dietary changes because more would be needed. However, to be safe, discuss this with your healthcare provider.

Excessive amounts of brassica vegetables, including cauliflower, can interfere with iodine absorption into the thyroid. Researchers believe this will only be an issue for iodine-deficient people who eat a lot of these vegetables.

How to Cook Cauliflower to Enjoy for Health

Many people wonder if raw or cooked cauliflower is better for them nutritionally. And it’s true: how many nutrients you get for your health from cauliflower may depend on how you cook it.


Studies show that cooking and blanching cause nutrient loss, but steaming, stir-frying, and microwaving retain most of the nutrients in cooking.

Fresh cauliflower has higher antioxidant levels than cooked cauliflower. The retention of antioxidants after cooking was highest after the cauliflower was rinsed with cold water, steamed, stirred, and microwaved.


Cauliflower is a nutrient-dense superfood, including fiber, antioxidants, vitamins, and minerals. It’s a low-carb diet, making it ideal for people on a keto or gluten-free diet because it can be made with flour and rice.

But it can be especially gassy, so people with digestive problems may want to start small and see how their bodies respond. Raw is the strongest, followed by steam stirring.
