Broccoli Protects Against Ultraviolet Radiation

Broccoli as a Sunscreen


Broccoli is well known for its benefits to the body, it lowers choloesterol and helps detoxify the body and blood, it is loaded with vitamin D as well as Vitamins A and K. Broccoli is also packed with the flavonoid kaempferol which can lessen the negative allergic reactions our bodies display to various substances. Broccoli also acts as an anti inflamatory agent. It's prized for it's documented ability to help avert various Cancers.



A recently discovered benefit of Broccolli comes from the substance found in cruciferous vegetables such as Brussels sprouts, cabbages and broccoli. Broccoli also contains elevated levels of glucoraphanin which not only has anti- carcinogenic properties but is converted into sulforaphane by the body. Sulforaphane will help protect the body from the harmful effects of UV radiation aka excessive exposure to the sun. In effect it reduces the risk of skin cancer.

A study by Dr. Paul Talalay and colleagues at Johns Hopkins University has found that the extract from Broccoli sprouts which is high in sulforaphane, when applied topically to the skin absorbs the UV rays before they can enter. It creates a barrier that no chemical or natural sunblock has been able to match.



The broccoli sprout extract drives protective enzymes into the pores and will help to protect the skin on a cellular level from uv radiation damage. The proteins will protect the skin cells for days, even after the extract has been washed away.




As per Dr. Talalay ... "the cells contain an elaborate network of protective genes that code for proteins that protect against four principal injurious processes to which all of our cells are exposed and which are the causes of cancer, degenerative disease and aging,.... oxidation; DNA damage; inflammation and radiation..." In particular ultraviolet radiation.

The study by Johns Hopkins demonstrated that the broccoli extract reduced skin redness and inflammation by nearly 40% and was still effective when applied 3 days prior.



Broccoli Sprout-Derived Extract Protects Against Ultraviolet Radiation [John Hopkins University]

"A team of Johns Hopkins scientists reports in this week’s issue of the Proceedings of the National Academy of Sciences that humans can be protected against the damaging effects of ultraviolet (UV) radiation - the most abundant cancer-causing agent in our environment - by topical application of an extract of broccoli sprouts.

The results in human volunteers, backed by parallel evidence obtained in mice, show that the degree of skin redness (erythema) caused by UV rays, which is an accurate index of the inflammation and cell damage caused by UV radiation, is markedly reduced in extract-treated skin.

Importantly, notes investigator Paul Talalay, M.D., professor of pharmacology, this chemical extract is not simply a sunscreen. Unlike sunscreens, it does not absorb UV light and prevent its entry into the skin. Rather, the extract works inside cells by boosting the production of a network of protective enzymes that defend cells against many aspects of UV damage. Consequently, the effects are long-lasting; the protection lasts for several days, even after the extract is no longer present on or in the skin."
