Why organic tomatoes are good for you
I’ve been meaning to blog this for almost a month. R. Ford Denison (a name to reckon with) blogged about some of his own research that summarizes 10 years of research into the flavonoid content of tomatoes grown conventionally and organically. Bottom line is that the organic tomatoes contained almost double the flavonoids of conventionals. I’m not going to go into whether that’s a good thing or not. Instead, I’ll stress the point that Denison himself makes, about Darwinian agriculture.
Why do the organic tomatoes contain more flavonoids? Maybe because flavonoids play a part in combatting herbivory. And they are often produced in response to pest attacks, rather than all the time. So one reason that organic tomatoes contain more of these compounds — which are believed to be good for human health — is precisely because on an organic farm there are a few pests that attack the plants. No pests, no need for defense, no benefits for human health.
This is just one aspect of what Denison calls Darwinian agriculture, a fascinating approach to the whole question of just what is being selected. There is, as someone else wrote, grandeur in this view of life …
A devoted gardner speaks
Michael Pollan looks at things from the point of view of agricultural biodiversity, and concludes we are all being manipulated by corn. ((Thanks to Hugh for the headsup.)) ((Sorry, the video is slightly wider than the column, but that’s down to the folks at TED, not us, and there’s nothing we can do about it other than distort Pollan.))

More complicated than it seems; feral pigs may have contaminated organic California spinach.
