Here is an overview of the nutrients found in 1 cup, or 128 grams, of raw cauliflower (1):
- Calories: 25
- Fiber: 3 grams
- Vitamin C: 77% of the RDI
- Vitamin K: 20% of the RDI
- Vitamin B6: 11% of the RDI
- Folate: 14% of the RDI
- Pantothenic acid: 7% of the RDI
- Potassium: 9% of the RDI
- Manganese: 8% of the RDI
- Magnesium: 4% of the RDI
- Phosphorus: 4% of the RDI
Summary: Cauliflower is an excellent source of vitamins and minerals, containing some of almost every vitamin and mineral that you need.
2. High in Fiber
Cauliflower is quite high in fiber, which is beneficial for overall health.
There are 3 grams of fiber in one cup of cauliflower, which is 10% of your daily needs (1).
Summary: Cauliflower contains a high amount of fiber, which is important for digestive health and may reduce the risk of several chronic diseases.
3. Good Source of Antioxidants
Cauliflower is a great source of antioxidants, which protect your cells from harmful free radicals and inflammation.
Similar to other cruciferous vegetables, cauliflower is particularly high in glucosinolates and isothiocyanates, two groups of antioxidants that have been shown to slow the growth of cancer cells (9, 10, 11, 12, 13).
In test-tube studies, glucosinolates and isothiocyanates have been shown to be especially protective against colon, lung, breast and prostate cancer (10).
What’s more, cauliflower contains high amounts of vitamin C, which acts as an antioxidant. It is well-known for its anti-inflammatory effects that may boost immune health and reduce the risk of heart disease and cancer (19, 20).
Summary: Cauliflower provides a significant amount of antioxidants, which are beneficial for reducing inflammation and protecting against several chronic diseases.
4. May Aid in Weight Loss
Cauliflower has several properties that may help with weight loss.
First, it is low in calories with only 25 calories per cup, so you can eat a lot of it without gaining weight.
It can also serve as a low-calorie substitute for high-calorie foods, such as rice and flour.
As a good source of fiber, cauliflower slows digestion and promotes feelings of fullness. This may automatically reduce the number of calories you eat throughout the day, an important factor in weight control (6, 8).
High water content is another weight loss friendly aspect of cauliflower. In fact, 92% of its weight is made up of water. Consuming lots of water-dense, low-calorie foods is associated with weight loss (1, 21).
Summary: Cauliflower is low in calories but high in fiber and water — all properties that may assist in weight loss.
5. High in Choline
Cauliflower is high in choline, an essential nutrient that many people are deficient in.
Choline has several important functions in the body.
Choline is also involved in brain development and the production of neurotransmitters that are necessary for a healthy nervous system. What’s more, it helps prevent cholesterol from accumulating in the liver (24).
Not many foods contain choline. Cauliflower, along with broccoli, is one of the best plant-based sources of the nutrient.
Summary: Cauliflower is a good source of choline, a nutrient many people are lacking. It is involved in many processes in the body and works to prevent several diseases.
6. Rich in Sulforaphane
Cauliflower contains sulforaphane, an extensively studied antioxidant.
Many test-tube and animal studies have found sulforaphane to be particularly helpful for suppressing cancer development by inhibiting enzymes that are involved in cancer and tumor growth (27, 28, 29).
Sulforaphane appears to be most protective against colon and prostate cancer but has also been studied for its effects on many other cancers, such as breast, leukemia, pancreatic and melanoma (29).
Finally, animal studies suggest that sulforaphane may also play a role in diabetes prevention and reducing the risk of diabetes-induced complications, such as kidney disease (30).
While more research is necessary to determine the extent of sulforaphane’s effects in humans, its potential health benefits are promising.
Summary: Cauliflower is rich is sulforaphane, a plant compound with many beneficial effects, such as reduced risk of cancer, heart disease and diabetes.
7. Low-Carb Alternative to Grains and Legumes
Cauliflower is incredibly versatile and can be used to replace grains and legumes in your diet.
Not only is this a fantastic way to increase your veggie intake, but it is also especially helpful for those who follow low-carb diets.
This is because cauliflower is significantly lower in carbs than grains and legumes.
Here are some examples of recipes that can be made with cauliflower instead of grains and legumes:
