Youth being recalcitrant about veggies
The Journal of the American Dietetic Association has a paper ((Impact of garden-based youth nutrition intervention programs: A review. Journal of the American Dietetic Association, Volume 109, Issue 2, Pages 273-280. R. Robinson-O’Brien, M. Story, S. Heim.)) which goes all meta on projects which aimed to encourage kids to eat more fruit and vegetables by getting them to work in gardens, for example at school. It covers the period 1990-2007, but only US-based studies, alas. I’m trying to get hold of the paper, but from the abstract it seems that the best that can be said about such interventions is that they may have a nutrition impact. We have blogged about how people are using school gardens etc. to educate yoofs about the importance of agrobiodiversity: it’s kind of sad to see that it is not entirely clear if the message is getting through.

Fighting osteoporosis with lettuce
Researchers have apparently engineered lettuce to express higher levels of the sCAX1 gene which pumps calcium into the cell’s vacuole, leading to 25-32% higher levels of the nutrient in the leaves. Sadly, there’s nothing in the article about genetic variation in Ca content among different varieties, so it’s not clear whether these increases could have been achieved by conventional breeding. Anyway, despite the paper, which I nibbled yesterday, showing the possibility of a link between Ca content and bitterness, there was apparently no difference in bitterness between the normal and biofortified lettuces. So that’s allright then.
Traditional African vegetables hit the mainstream
It’s not really all that long since we brought together researchers on that overlooked portion of African agrobiodiversity that is its traditional vegetables for one of the first ever times. I wonder how many of us ever thought that in little more that 10 years we would be able to buy terere and managu and the like wrapped in plastic and barcoded in supermarkets in Kenya:
Or indeed buy nicely packaged and labelled seed from small agricultural suppliers in places like Limuru:
Preparation is time-consuming and fiddly, sure:
But the taste and nutrients are worth it, as more and more people are finding out. We had some Amaranthus for Christmas lunch, from grandma’s shamba. Can’t get much more mainstream than that.
