What is Broccoli?

Broccoli may be a cruciferous vegetable, which belongs to the Italica cultivar group of Brassicaceae oleracea like cabbage and cauliflower. The most commonly eaten parts of it are the green or purple flowering heads, which are shaped like a tree, coming off a thick and edible stalk. [1]


There are many types of broccoli, which are popular in different parts of the world. The three main varieties are as follows.

  • Calabrese broccoli: It is the most common type, named after Calabria (Italy) and is simply called broccoli.
  • Sprouting broccoli: This variety has many heads and thin stalks.
  • Purple cauliflower: It is shaped like cauliflower and consists of tiny flower buds.
  • The other types include broccoli Rabe, Chinese broccoli, and broccoflower.

What Does Broccoli Taste Like?

Raw broccoli may generally has a mildly bitter taste like a cabbage. People with a particular receptor gene might be sensitive to some flavors and find it extremely bitter and unpleasant. This taste is because of the presence of natural compounds called glucosinolates.

Health Benefits of Broccoli

Health benefits of this cruciferous vegetable include the following:

May Aid in Digestion

Research on broccoli published in the Journal of Functional Foods revealed the results of an animal study conducted to check if broccoli is helpful in maintaining gut health. As part of the study, a group of mice was administered the green vegetable as part of their regular diet and it was seen that they were better able to tolerate their digestive issues such as colitis and leaky gut in comparison to those that were not given the green vegetable. It was thus concluded that the fiber content may have played a vital role in regulating digestion. Along with kaempferol, fiber also tends to keep the stomach lining healthy and helps maintain healthy bacteria levels in the intestines.

May Prevent Chronic Diseases

Broccoli may contain certain phenolic compounds that might help keep chronic diseases at bay. This may lower your chances of developing diabetes, asthma, heart disorders, and many other lethal diseases, thereby, decreasing mortality. Broccoli may be most effective when consumed with other healthy, disease-preventing foods that are not processed.

May Improve Liver Health

A 2016 report published in the Journal of Nutrition revealed that broccoli may help keep your liver functioning at its optimal level by lessening the development of fatty liver.

May Boost Brain Health

Broccoli may help boost cognition and memory because it is rich in vitamin K and choline. In addition to this, sulforaphane may also help aid in preventing the onset of Alzheimer’s and many neurodegenerative diseases.

May Aid In Hair Care

Nutrients, found in broccoli, like vitamins A and C might be great for keeping your hair shiny, thick, and healthy. These vitamins may also counter dry hair by regulating sebum production on the scalp to naturally moisturize hair leading to less brittle and fragile hair and reduces hair loss.

May Have Anti-inflammatory Properties

A 2014 study published in the Preventive Nutrition and Food Science Journal suggests that broccoli florets might have potent antioxidant and anti-inflammatory effects. It may have antioxidants like vitamin C, potassium, magnesium, sulforaphane, kaempferol, and many others, which makes this cruciferous vegetable good for relieving inflammation.

May Possess Anti-aging Properties

Broccoli may combat the aging process with the help of a compound called nicotinamide mononucleotide (NMN) present in it. NMN may promote the production of a compound that triggers metabolism and hence prevents genetic changes that lead to premature aging. Antioxidants like vitamin A, vitamin C, and collagen also play a key role in delaying aging.

May Help Control Diabetes

A 2012 study published in the International Journal of Food Sciences and Nutrition, may suggest that broccoli sprouts may improve insulin resistance in type 2 diabetic patients. To elaborate, it may suggest that sulforaphane and kaempferol in this cruciferous food might have the ability to lower blood sugar levels in those who have Type 2 Diabetes Mellitus diabetics, thereby helping control it. Broccoli in addition to a heart-healthy, carbohydrate-controlled diet is always encouraged for the best results when it comes to blood glucose control.

May Improve Metabolism

Nutrients such as fiber, vitamin C, vitamin D, vitamin K, folate, and vitamin A in broccoli may assist in boosting the body’s metabolism. Fiber, especially, shows a TEF (thermic effect of food) and may increase your metabolic rate after eating. It may also promote satiety by having a good amount of dietary fiber.

May Augment Sexual Libido

Broccoli might help boost blood circulation to the organs of the body and may help in improving libido. It contains folate and vitamin C, which can improve fertility.

May Detoxify the Body

The presence of vitamin C, sulfur, and amino acids may make broccoli a good detoxifier. It might help remove free radicals and toxins like uric acid from the body, thereby purifying the blood and keeping away toxin-related problems such as boils, itches, rashes, gout, arthritis, rheumatism, renal calculi, skin diseases like eczema, and hardening of the skin. It may also be an alkaline vegetable and can help balance the body’s pH levels.

May Help With Skin Care

Broccoli may aid in skincare and give you a glowing, healthy, and radiant appearance. The antioxidants like beta-carotene, vitamin A, vitamin B complex, vitamin C, vitamin E, vitamin K, amino acids, and folate, present in it, might do this magic.

May Protect From UV Rays

Glucoraphanin, a phytonutrient found in significant amounts in broccoli, may have been connected with reversing the negative effects of sun exposure.

May Offer Relief from Stomach Disorders

Broccoli may be very rich in fiber or roughage, which may help relieve constipation since that is the root cause of almost all the stomach disorders. Fiber adds to the bulkiness of the food, retains water, and stimulates healthy bowel movements. The magnesium and vitamins present in it may help reduce acidity, facilitate proper digestion, and aid in the absorption of nutrients from the other foods. It might also soothe the stomach by reducing inflammation. It is recommended that those who suffer from Irritable Bowel Disease as well as diverticulitis, may avoid roughage as this can cause flare-ups.

May Aid In Eye Care

Carotenoids like zeaxanthin, beta-carotene, and phosphorus, and other vitamins such as vitamin A, B complex, C, and E found in broccoli may be very good for ocular health. These substances can be used to protect eyes against macular degeneration and cataracts, while also repairing the damage caused by radiation.

May Boost Immunity

Broccoli may derive its purple and green color from antioxidants like vitamin C, beta-carotene, selenium, copper, choline zinc, and phosphorus. These compounds present may be really great immune system boosters and they might protect you from numerous infections. In addition to eating a balanced diet, it is encouraged to get adequate sleep and manage stress to see the best results.

May Improve Bone and Teeth Health

Broccoli may keep the bones and teeth strong as it is rich in vitamin K, calcium, magnesium, zinc, and phosphorus. Eating the vegetable can be very beneficial, particularly for children, elderly people, and/or pregnant or lactating women. Children and older adults may be very prone to osteoporosis, weakening of bones and teeth, and calcium deficiency. Moreover, vitamin K is essential for the formation of osteocalcin, which is a protein, only found in bones.

May Help Fetal Development During Pregnancy

Broccoli might be full of nutrients essential for pregnant women. It may contain proteins, calcium, vitamins, antioxidants, iron, and phosphorus. Being rich in fiber, it may also eliminate constipation, which is very common during pregnancy. The folate content in these vegetables might help ensure that there are no birth defects such as neural tube defects, which is a major problem for pregnant women who have a folic acid deficiency in their diet. It is still recommended that women take prenatal vitamins or take what is instructed by their OB/GYN.

May Regulate Blood Pressure

Chromium, found abundantly in broccoli, may help regulate blood pressure. Also, the nutritious amount of potassium in broccoli might act as a vasodilator. More specifically, potassium may help improve blood flow and oxygenation of essential organs by relaxing tension and stress of veins and blood vessels. Magnesium and calcium may also aid in regulating blood pressure and can help keep the heart protected from cardiovascular diseases like strokes or heart attacks.

May Fight Anemia

The vegetable may be rich in iron and protein and hence, forms an excellent remedy against anemia. Copper might also be another essential mineral in the production of red blood cells, along with iron. So include this green vegetable in your diet and help prevent iron-deficiency anemia.
