Broccoli: a new sunscreen that lets in vitamin D
In tests on people and mice, broccoli extract successfully prevented cancer caused by light and it did so in a really interesting way. Sunscreens usually provide a barrier to either UV or UB rays. This means that they also block out vitamin D. Broccoli works by stimulating the body's own cancer protection mechanisms. And once they get switched on they can keep going for days after you've showered off the sunscreen. Best of all, you will be protected but not missing out your much-needed daily dose of D.
Verdure's coyness about using broccoli may be due to the fact that the research, conducted at the John Hopkins School of Medicine, is so new. The other problem that may slow down the use of broccoli in sunscreens is that the pigment, which could give you a Martian hue, is difficult to remove.
UPDATE 5/6/2008: I ordered a tube of Verdure Matte and it has just arrived. There is a huge laundry list of ingredients. Most of them are emollients and silicones. Unfortunately, there are two many known irritants as well: sodium hydroxide (very low levels will irritate); phenoxyethanol; ethylhexylglycerin; and hexylene glycol.
