There’s kind of an interesting post and discussion at the Biodiversity Weblog about a study showing another reason why organic vegetables may be better for you than conventional.

If I may be so bold as to condense a 10 year study into a few words, the basic idea is that many plants have natural defence mechanisms to pests that cause them to produce substances (in this case flavonoids in tomatoes) which seem to have a benefit to human health.

This may be part of the reason organic or home grown produce tastes different too.

Depending on your point of view I suppose, this is either justification for more research into this mechanism in order to devise ways of producing healthier foods, or it’s another reason we should be eating more natural foods.
