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.
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."
