Broccoli Calories

A 100 gm serving of raw broccoli has approximately 32 calories, making it an excellent choice to add to meal when trying to induce weight loss. Broccoli can help promote satiety due to its fiber content thus keeping you fuller for longer periods.

Health Benefits of Broccoli

Health benefits of this cruciferous vegetable include the following:

Aids 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 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.

Prevents Chronic Diseases

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

Liver Health

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

Boosts Brain Health

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

Hair Care

Nutrients, found in broccoli, like vitamins A and C 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. This leads to less brittle and fragile hair and reduces hair loss.

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. It has antioxidants like vitamin C, potassium, magnesium, sulforaphane, kaempferol, and many others, which makes this cruciferous vegetable good for relieving inflammation.

Anti-aging 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 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.

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. To elaborate, it suggests 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.

Improves Metabolism

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

Improves Sexual Libido

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.

Detoxifies the Body

The presence of vitamin C, sulfur, and amino acids make broccoli a good detoxifier. 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, gout, arthritis, rheumatism, renal calculi, skin diseases like eczema, and hardening of the skin. It is also an alkaline vegetable and can help balance the body’s pH levels.

Skin Care

Broccoli aids in skincare and gives 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, do this magic.

Protects from UV Rays

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

Relief from Stomach Disorders

Broccoli is very rich in fiber or roughage, which helps 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 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 (Crohn’s or ulcerative colitis) as well as diverticulitis, avoid roughage as this can cause flare-ups.

Prevents Heart Disease

Along with the antioxidant glucoraphanin, the high-fiber content in broccoli helps reduce LDL or bad cholesterol levels and keep the heart functioning properly. 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.

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). Plus, 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. These compounds present are really great immune system boosters and they can 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.

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, elderly people, and/or pregnant or lactating women. Child and older adults are 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.

Helps Fetal Development During 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. The folate content in these vegetables helps to 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.

Regulates Blood Pressure

Chromium, found abundantly in broccoli, helps to regulate blood pressure. Also, the nutritious amount of potassium in broccoli can act as a vasodilator. More specifically, potassium helps improve 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 can help keep the heart protected from cardiovascular diseases like strokes or heart attacks.

Fights Anemia

The vegetable is rich in iron and protein and hence, forms an excellent remedy against anemia. 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 help prevent iron-deficiency anemia.

How to Select Broccoli?
