 Tangerine peel 'kills cancer' |  A compound extracted from tangerine peel can kill certain human cancer cells, research shows. A team from Leicester School of Pharmacy found Salvestrol Q40 was turned into a toxic compound in cancer cells, destroying them.
Salvestrol 40 is a type of phytoalexin - a chemical produced by plants to repel attackers, such as insects or fungi. It is converted into a toxic compound by the P450 CYP1B1 enzyme, found in much higher levels in cancer cells. As a result, the researchers found, it proved to be 20 times more toxic to cancer cells than their healthy equivalents
Salvestrol Q40 is found at higher concentrations in tangerine peel, than in the flesh of the fruit. The researchers suggest the modern trend to throw away peel may have contributed to a rise in some cancers...

The full story adds a point which I think validates the "only eat organic" talking points.
However, the compound tends to be produced at higher levels when infection levels among crops are high.
Therefore, the use of modern pesticides and fungicides, which have cut the risk of infections, have also led to a drop in Salvestrol levels in food.
I'm also wondering about the peel as such because of this quote:
The researchers suggest the modern trend to throw away peel may have contributed to a rise in some cancers.
As I understood it peel and skin is the same thing, but this makes it read like the peel is the white thing under the skin, otherwise I don't understand the "modern trend to throw away peel".

I think this is an very interesting subject, so i have postet one of the projekt that i wrote in 2004, which touches the subject. I especially like the notion of interspecific and intraspecific competition between plants.
