Interesting story in the papers the last few days about how sales of beetroot have risen since it was reported to lower blood pressure.
There was a similar one a while ago about blueberries -- how popular they have become since they were shown to be a good source of phytochemicals.
I think it shows that people do take in information, and do care about healthy eating.
Contrary to the popularised media vision of people who have no idea, or don't care, and just eat "junk food" whatever that is. Whenever the public get any clear and credible message, they'll go for it. I'm sure the "dark chocolate good for you" one has sunk in too -- the supermarket shelves seem to devote much more space than they ever used to to chocolate with 70% cocoa or more.
