Nutritional benefits of broccoli
There have been many health claims over the years about broccoli and whether it could be labelled a 'superfood' or not, but its nutrient-rich profile does offer some real health benefits.
Broccoli is a good source of fibre and protein, and contains iron, potassium, calcium, selenium and magnesium as well as the vitamins A, C, E, K and a good array of B vitamins including folic acid.
Discover more about why we need fibre, vitamins and minerals.
Is broccoli good for heart health?
A study by Nutrition Research found that consuming steamed broccoli regularly lowers the risk of cardiovascular disease by reducing the total amount of cholesterol in the body. Another study in the US also found that increasing vegetables in the diet, especially cruciferous vegetables like broccoli, could reduce the risk of heart disease.

Can broccoli help build strong bones?
Vitamin K is an essential nutrient that is needed for blood clotting, and may play an important role in keeping our bones healthy and strong. Whilst more research is needed, there has been consistent evidence that vitamin K can improve bone health in general as well as increasing bone mineral density and reducing fracture rates in those with osteoporosis.
Adults need 1 mcg of vitamin K per kilogram of body weight, which means a 75kg adult would need 75mcg of vitamin K a day. Just 100g steamed broccoli provides 145mcg of vitamin K, so this nutrient can be easily achieved through diet alone.
Please note, if you are taking blood thinners such as warfarin, you need to be mindful of your vitamin K consumption as it may interact with the medication, so check with your GP before making any dietary changes.

Is broccoli good for eye health?
Broccoli contains certain carotenoids called lutein and zeaxanthin that, in studies in 2006 and 2003, were linked to a decreased risk of age-related eye disorders, such as cataract and macular degeneration. Night blindness is also associated with a deficiency of vitamin A. Broccoli contains beta-carotene which the body converts to vitamin A.
Can broccoli help prevent cancer?
While there are no single 'superfoods' that can prevent cancer and certain risk factors for cancer are unrelated to diet, there is evidence that eating a healthy diet can reduce the risk of cancer. A key component of broccoli is a phytochemical known as sulforaphane, which also gives broccoli a slight bitter taste.
Studies have shown that sulforaphane may play a part in enhancing detoxification of airborne toxins, such as cigarette smoke, and could help reduce the risk of certain cancers. Further research has suggested that broccoli may have anti-cancer properties and could reduce the risk of prostate cancer.
Broccoli sprouts are, in fact, a more concentrated source of these cancer-fighting compounds. These can easily be sprouted from seed on your windowsill, just like growing cress.
Is broccoli best eaten raw or cooked?
A 2008 report by the Journal of Agriculture and Food Chemistry found that boiling and steaming was best for preserving broccoli’s antioxidant status, but that cooking can destroy vitamin C. Another piece of research, however, demonstrated that raw broccoli was best when it comes to preserving the levels of sulforaphane. In short, whether you eat broccoli raw or cooked, it is a valuable addition to a balanced diet.
