Broccoli Nutrition & Calories - Complete data of all nutrients
While broccoli is not incredibly dense in macronutrients, it is an excellent source of vitamins and minerals, including vitamin C, vitamin K, potassium, and manganese.
Broccoli is also rich in health-beneficial phytochemicals, such as glucosinolates and polyphenols. These compounds have expressed anticancer and antidiabetic qualities among others.
Steaming is the preferred method of cooking broccoli as fewer nutrients are lost this way.
Broccoli is often regarded as a token of a healthy lifestyle due to its nutritional value and numerous health benefits. In this article, we will discuss in detail the ingredients of broccoli and see what sets this vegetable apart from others.
Table of contents
The nutritional information and infographics in this article will focus on raw broccoli. We will discuss the nutritional alteration of broccoli due to various cooking methods below.
Overall, raw broccoli consists of 90% water and 10% nutrients.
One average serving size of broccoli per person weighs 148g.
Broccoli is a low-calorie food, providing only 34 calories per 100g serving. Subsequently, one average serving size of broccoli contains 50 calories.
Broccoli can be a great addition to a diet as a source of protein.
One average serving size of broccoli provides 4g of protein.
The protein found in broccoli contains all essential amino acids and is particularly high in tryptophan while being relatively low in leucine.
A 100g serving of broccoli covers 12% of your daily tryptophan need.
Protein quality breakdown
Broccoli contains 6.64g of carbohydrates per 100g serving, of which 39% is made up of dietary fiber (2.6g) and 61% of net carbs (4.04g).
Broccoli contains predominantly insoluble dietary fiber. Of the 2.6g of dietary fiber found in broccoli, 91% is insoluble fiber, and only 9% is soluble fiber (1).
Fiber content ratio for Broccoli
The net carb content consists of 1.7g of sugar and 2.34g of other carbohydrates.
The sugar content of broccoli includes low levels of various sugars such as fructose, glucose, lactose, maltose, and sucrose.
Carbohydrate type breakdown
Broccoli contains a negligible amount of fats, only 0.37g per 100g serving.
Like other plant-based foods, broccoli naturally contains no cholesterol.
Fat type information
There’s a reason why broccoli is so often associated with healthy eating. Despite the low-calorie content, broccoli is an excellent source of many vitamins.
Broccoli falls in the top 10% of foods as a source of vitamin C.
Just a 100g serving of raw broccoli can cover the daily need for vitamin C. In fact, broccoli is 1.7 times higher in this vitamin compared to oranges.
Broccoli is also in the top 23% of foods as a source of vitamin A. However, a 100g serving of this vegetable covers only 12% of the daily vitamin A needs.
A 100g serving of broccoli also covers 85% of the daily required amount of vitamin K.
Broccoli provides adequate levels of vitamin E and B complex vitamins, especially vitamin B9 or folate.
Broccoli, however, entirely lacks vitamin D and vitamin B12.
Vitamin coverage chart
Broccoli is also rich in minerals. It falls in the top 35% of foods as a source of potassium and calcium.
Broccoli is a good source of manganese, iron, magnesium, and phosphorus while also containing some levels of zinc, selenium, copper, and choline.
Broccoli without added salt contains only 33mg of sodium. However, boiling broccoli with salt raises the sodium level to 262mg (2). Regardless, both forms of broccoli are low in sodium.
The daily recommended amount of sodium intake is between 3 and 5g (3).
Mineral coverage chart
Another reason for broccoli’s appreciable health-beneficial qualities is its phytonutrient content.
The Brassicaceae family of broccoli is abundant in sulfur-containing phytochemicals called glucosinolates. Broccoli contains the highest level of glucoraphanin amongst commonly consumed vegetables of this family, including cabbage, cauliflower, and Brussel sprouts. There is strong evidence that sulforaphane derived from glucoraphanin can be protective against cancer (4).
The broccoli family is also rich in polyphenols, including phenolic acids and flavonoids. Some of these compounds found in broccoli are chlorogenic, gentisic, ferulic, and sinapic acids (5). All of these chemicals contain strong antioxidant qualities that can reduce cell damage.
Polyphenols have also been studied to potentially prevent diabetes, ulcers, osteoporosis, cancer, neurodegenerative and cardiovascular diseases (6).
Research shows that cooking methods such as boiling, microwaving, and stir-frying causes broccoli to lose some of its antioxidant and nutrient content, including vitamin C, soluble proteins, and sugars. Steaming broccoli does not have the same adverse effects.
The glucosinolate phytonutrients can also be significantly reduced by these cooking methods but not by steaming (7).
Boiling broccoli can reduce its vitamin C content by up to 33%, while microwaving decreases this vitamin by 16% (7).
The boiling process drains the broccoli of its water-soluble vitamins and macronutrients; therefore, it is not an ideal preparation method. Instead, it is better to steam, briefly microwave, or simply eat it raw. Alternatively, you can use the leftover water from boiling broccoli.
The glycemic index value of broccoli has not yet been calculated due to the low sugar content; however, it is assumed to be low.
Due to their high sulforaphane content, broccoli sprouts are researched to be an excellent choice for supplementary treatment in type 2 diabetes (8).
Eating broccoli before a rice meal was shown to decrease the glycemic response of the meal while lowering insulin sensitivity (9).
The insulin index demonstrates how much the given food raises the insulin level in the body after consumption.
Broccoli has an insulin index of 29 (10). This means that broccoli is considered to be a low insulin index food and can be recommended to diabetic individuals.

Broccoli has a pH value of around 6.23, making this vegetable slightly acidic. At room temperature, the pH of broccoli is a little closer to neutral - 6.54 (11).
However, when looking at the potential renal acid load or the PRAL value of broccoli, we can see that it is slightly alkaline-forming in the body.
Comparison to Similar Foods
In this section, we will compare broccoli to similar and popular vegetables. It is important to note that broccoli, broccoli rabe, and Chinese broccoli are separate vegetables.
Compared to cabbage, broccoli is slightly higher in calories, protein, carbohydrates, including both fiber and net carbs, vitamins, and minerals.
If interested, you can find a full comparison article of “Broccoli vs. Cabbage”.
In comparison to cauliflower, broccolis is richer in calories, protein, dietary fiber, vitamins, and minerals, while cauliflower is higher in sugars. You can also find a complete “Broccoli vs. Cauliflower” comparison.
When looking at the “Broccoli vs. Chinese Broccoli” comparison, once again, broccoli is richer in calories, protein, net carbs, and dietary fiber. However, when it comes to vitamins and minerals, both of these vegetables have their advantages.
