Health Benefits of Eating Broccoli

Adding broccoli in your weekly keto diet meal plan not only helps you in your overall weight loss journey but also comes with other health benefits. Several studies support the fact that broccoli can help in disease prevention and boosting your overall body health.

Diabetes and Autism

For people with type 2 diabetes, broccoli extracts may be what you need to stay healthy. Sulforaphane in broccoli and other cruciferous vegetables like Brussels sprouts and cabbage could inhibit the activity or expression of the different genes associated with type 2 diabetes.

Scientists gave the extract to 97 people with type 2 diabetes in three months. While non-obese participants in the research never saw any effects, the obese saw the glucose levels decrease by 10% compared with the control group. However the doses administered to these individuals is 100 times that found naturally in broccoli.

Additionally, sulforaphane was also found to relieve symptoms related to autism. Participants who took this extract showed significant improvement in social interactions and verbal communications. (Source)


Broccoli may be what your doctor ordered for osteoarthritis treatment. It’s also an excellent anti-inflammatory remedy which can significantly reduce joint damages associated with osteoarthritis.

According to a 2013 research by University of East Anglia, broccoli’s sulforaphane can help relieve arthritis symptoms. This chemical compound blocks the enzymes responsible for joint destruction by stopping the main molecule that causes inflammation.

Additionally, broccoli is rich in omega-3 fatty acids and isothiocyanates that help regulate inflammation. A 2010 study suggested that flavonoid kaempferol found in broccoli help reduce the impacts of allergens in the intestinal tract, which can prevent chronic inflammation.

Cancer prevention

Many of the keto-friendly vegetables and fruits have anti-cancer benefits. Eating cruciferous vegetables has been linked with lower risks of cancer particularly colon and lung cancer. This can be attributed to sulforaphane, a chemical extract containing sulfur, which gives cruciferous veggies their bitter taste.

Studies have found out that this chemical compound can hinder the enzyme histone deacetylast (HDAC) known to facilitate the growth of cancer cells.

Additionally, broccoli contains an important vitamin (folate), which has been shown to decrease the risk of breast cancer. Sufficient amounts of this vitamin have also shown to help prevent against stomach, colon, cervical and pancreatic cancers. (Source) While the mechanism behind cancer protection isn’t fully understood, scientists believe that it may be something to do with folate’s role in RNA and DNA production and mutations prevention.

Glowing Tight Skin

Broccoli contains antioxidant vitamin C., And when eaten raw it can help prevent skin damage caused by ultraviolet rays from the sun and pollution. It also helps prevent wrinkles and improves skin texture.

One cup of broccoli provides 81 milligrams, which is more than recommended daily value. Vitamin C plays a crucial role in collagen formation which is the primary support system for the skin. Additionally, vitamin A and E in broccoli are also vital for healthy-looking skin.

Enhance the immune system

Vitamin C in broccoli plays a vital role in both innate and adaptive immunity. In addition, studies have confirmed that the chemical compound sulforaphane in broccoli helps in enhancing immune system functioning. (Source)
