24 Incredible Benefits Of Broccoli
Broccoli has a wide variety of health benefits, including its ability to prevent cancerimprove digestion, lower cholesterol levels, detoxify the body, and maximize vitamin and mineral uptake. It also prevents allergic reactions, boosts the immune system, protects the skin, prevents birth defects, lowers blood pressure, eliminates inflammation, and improves vision and ocular health.

What is Broccoli?

Broccoli is a green vegetable, which belongs to the Italica cultivar group of Brassicaceae oleracealike cabbage and cauliflower. [1] 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.


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 generally has a mildly bitter taste like a cabbage. People with a particular receptor gene are sensitive to some flavors and hence, find it extremely bitter and unpleasant. This taste is actually because of the presence of natural compounds called glucosinolates.

Health Benefits of Broccoli

Health benefits of this cruciferous vegetable include the following:

Aids in Digestion

study was carried out by Gary Perdew, the John T. and Paige S. Smith Professor in Agricultural Sciences, Penn State, USA, to test if broccoli is helpful in maintaining gut health. [4] 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 played a vital role in regulating digestion. Along with kaempferol, it also tends to keep the stomach lining healthy and helps maintain healthy bacteria levels in the intestines.

Prevents Chronic Diseases

Broccoli contains certain phenolic compounds that help keep chronic diseases at bay. [5] This lowers your chances of suffering from, diabetesasthmaheart disorders, and many other lethal diseases, thereby, decreasing mortality.

Liver Health

A 2016 report published in the Journal of Nutrition revealed that broccoli can keep your liver functioning at its optimal level. [6] Non-alcoholic fatty liver disease (NAFLD) is linked to excess fat and can lead to liver cancer and cirrhosis.

Boosts Brain Health

Rich in vitamin K and choline, broccoli helps boost cognition and memory. In addition to this, sulforaphane in it also aids in preventing the onset of Alzheimer’s and many neurodegenerative diseases. [7]

Hair Care

Nutrients like vitamin A and vitamin C, found in broccoli, are great for keeping your hair shiny, thick, and healthy. These vitamins also counter dry hair by regulating sebum production on the scalp to naturally moisturize hair. [8] This leads to less brittle and fragile hair and reduces hair loss.

Reduces Allergies

Vitamin C-rich broccoli is great for reducing allergy symptoms. It is known to lessen the effects of pollution and keep you free of allergic reactions.

Anti-inflammatory Properties

A 2014 study published in the Preventive Nutrition and Food Science Journal suggests that broccoli florets have potent antioxidant and anti-inflammatory effects. [9] It has antioxidants like vitamin C, potassium, magnesium, sulforaphane, kaempferol, and many others, which makes this cruciferous vegetable good for relieving inflammation.

Antiaging Properties

Broccoli combats the aging process with the help of a compound called nicotinamide mononucleotide (NMN) present in it. NMN promotes the production of a compound which 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. [10]

Controls Diabetes

A 2012 study published in the International Journal of Food Sciences and Nutrition, suggests that broccoli sprouts may improve insulin resistance in type 2 diabetic patients. [11] To elaborate, it suggests that sulforaphane and kaempferol in this cruciferous food have the ability to lower blood sugar levels in diabetics, thereby helping control it.

Improves Metabolism

Nutrients such as fiber, vitamin C, vitamin D, vitamin K, folate, and vitamin A in broccoli assist in boosting body metabolism. Fiber, especially, shows a TEF (thermic effect of food) and increases your metabolic rate after eating.

Improves Sexual Performance

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

Anti-cancer Potential

Broccoli has anti-cancer potential. It is particularly beneficial for breast cancer and uterine cancer since it removes extra estrogen from the body. Dr. Jay Fowke, the University of Massachusetts, as part of his dissertation [12]“A Dietary Strategy to Reduce Breast Cancer Risk,” revealed that it could help produce a positive shift to the metabolites of estrogen called 2 hydroxyestrone ie. 2-OHE1 in post-menopausal women. Daily consumption of 500 grams or merely an over a pound of broccoli, twice a day, helped bring down the estrogen levels in the body. Additionally, it demonstrated that it may be an important component of a strategy to reduce breast cancer risk.
Senior researcher, Jed W Fahey, The Johns Hopkins University School of Medicine, in his report published in the Proceedings of the National Academy of Sciences of the United States of America, stated that broccoli has the presence of strong anti-carcinogenic compounds like sulforaphane, glucoraphanin, diindolylmethane, isothiocyanates, beta-carotene, and selenium in it. [13] Other nutrients which act as anti-cancer agents are vitamin C, A, and E, zinc, potassium and certain amino acids.

Detoxifies the Body

The presence of vitamin C, sulfur, and amino acids make broccoli a very good detoxifier. [14] It helps 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, goutarthritis, rheumatism, renal calculi, skin diseases like eczema, and hardening of the skin. It is an alkaline vegetable that helps balance the body’s pH levels.

Skin Care

Broccoli aids in skin care and gives you a glowing, healthy, and radiant appearance. The antioxidants like beta-carotene, vitamin A, vitamin Bcomplex, vitamin C, vitamin E, vitamin K, omega 3 fatty acids, amino acids, and folate, present in it, do this magic. [15]

Protects from UV Rays

Glucoraphanin, a phytonutrient found in significant amounts in broccoli, has been connected with reversing the negative effects of sun exposure. [16] You can turn back the clock on your skin by eating plenty of this beneficial vegetable.

Treats Stomach Disorders

Broccoli is very rich in fiber or roughage, which helps cure constipation since that is the root cause of almost all the stomach disorders. [17]Fiber adds to the bulkiness of the food, retains water, and stimulates healthy bowel movements. The magnesium and vitamins present in it cure acidity, facilitate proper digestion and absorption of nutrients from the food and soothe the stomach by reducing inflammation.

Prevents Heart Diseases

Along with glucoraphanin, the high-fiber content in broccoli helps reduce LDL or bad cholesterol levels and keep the heart functioning properly. [18] Also, reducing bile has a strong impact on cholesterol levels, thereby helping your heart health. Studies have shown that the fiber combines better with bile, making it much easier and efficient to excrete. Kaempferol is a flavonoid that also aids in keeping the heart healthy owing to its anti-inflammatory properties.

Eye Care

Carotenoids like zeaxanthin, beta-carotene, and phosphorus, and other vitamins such as vitamin A, B complex, C, and E found in broccoli are very good for ocular health. These substances protect eyes against macular degeneration and cataracts, while also repairing the damage caused by radiation. [19]

Amyotrophic Lateral Sclerosis

A Harvard Medical research paper suggests that broccoli is rich in beta-carotene, which when consumed causes nearly a 25 percent less risk of amyotrophic lateral sclerosis (ALS). [20] Besides, it contains omega 3 fatty acids, which also helps in preventing ALS. Recent research suggests that intake of diet rich in omega-3 fatty acids may reduce or delay the onset of Lou Gehrig’s disease.

Boosts Immunity

Broccoli derives its purple and green color from antioxidants like vitamin C, beta-carotene, selenium, copper, choline zinc, and phosphorus. [21] These compounds present are really great immune system boosters and they can protect you from numerous infections.

Improves Bone and Teeth Health

Broccoli keeps 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, old people, and pregnant or lactating women. That’s because these are the people most prone to osteoporosisweakening of bones and teeth, and calcium deficiency. [22] Moreover, vitamin K is essential for the formation of osteocalcin, which is a protein, only found in bones.

Helps in Pregnancy

Broccoli is full of nutrients essential for pregnant women. It contains proteins, calcium, vitamins, antioxidants, iron, and phosphorus. Being rich in fiber, it also eliminates constipation, which is very common during pregnancy. [23] The folate content in these vegetables ensures 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.

Regulates Blood Pressure

Chromium, found abundantly in broccoli, helps in the proper functioning of insulin and regulates blood sugar, thereby regulating blood pressure as well. [24] Also, potassium, found in it, is a vasodilator. It helps boost blood flow and oxygenation of essential organs by relaxing tension and stress of veins and blood vessels. Magnesium and calcium also aid in regulating blood pressure and keep the heart protected from cardiovascular diseases like strokes or heart attack.

Treats Anemia

Broccoli is rich in iron and protein and hence, forms an excellent remedy against anemia. [25] Copper is also another essential mineral in the production of red blood cells, along with iron. So include this green vegetable in your diet and prevent anemia.
