Getting enough vitamin A in Kenya

There’s an interesting juxtaposition of material in today’s Nation. Unfortunately, none of it is online so you’ll just have to take my word for it, unless you live in Kenya that is. On the one hand there’s an advertising feature announcing the launch of fortified fats and oils. The four-page spread says that “a team representing government, the standards setting body, testing agencies and the private sector brought Vitamin A-fortified oil to the supermarket shelves in only 130 days.” It includes statements by the Ministers of Health and of Trade & Industry, the Director of Medical Services, the Director of the Bureau of Standards, the Director of the Kenya Medical Research Institute and the Africa Regional Director of the Micronutrient Initiative. The mid-term review of the effort is on the Micronutrient Initiative website here.

Interestingly, the Ministry of Agriculture seems not to have been involved, but in a different part of the paper there’s an article about the widespread and rapid adoption of new, vitamin A-rich sweet potato varieties by communities in western Kenya as part of a project funded by Farm-Africa under the Community Mobilisation Against Desertification (CMAD) programme, in which that ministry did take part. A women’s group in Homa Bay has set up a bakery that uses sweet potato flower mixed with wheat to make bread, cakes and other products for local schools and hospitals.

So, two contrasting ways of trying to achieve the same thing: and end to hidden hunger. I wonder which approach will end up proving better value for money? Do we need both?

More tea, vicar?

You may remember an earlier – somewhat facetious – post on a possible threat to tea diversity in China. Now, from CropBiotech Update, there’s a summary of a far from facetious review paper on tea breeding in that country. Turns out that the China National Germplasm Tea Repositories can count on some 3000 tea germplasm accessions, and that over 200 improved varieties have been released. Some quite advanced biotechnological approaches are being used to speed up breeding. One of the things the researchers are looking at is developing cultivars with low or no caffeine, using RNAi. Personally, I think caffeine-free tea and coffee, like alcohol-free beer, are a bit like a one-legged man at a butt-kicking contest: useless. But the technology is cool.

Bees in trouble

This short piece from EurekAlert describes research in Spain which compared lots of different honeys and showed that the best for antioxidants is that which bees make from honeydew, the exudate produced by plants when they’ve been attacked by sap-sucking bugs. So let’s all go out and eat more honeydew honey, right? Well, we better be quick about it. Unfortunately, according to this other piece coincidentally also published today, life for European bees is set to get considerably more difficult, due to the incursion of Chinese wasps. It is already pretty bad for American bees in 22 states due to something nasty called Colony Collapse Disorder, according to this. Which completes today’s trifecta.

Brazil to market biodiversity

Under an Environment Ministry initiative in Brazil research groups have selected 775 species to encourage production and hopefully develop major markets. Read about it here:

Five books will be published this year, each dedicated to one of the five major regions of Brazil, containing the knowledge that has been accumulated about these “plants of the future”. Seminars for the business community will be held to spread the word about the potential of these plants, which are ornamental or used to produce foods, beverages, medicines, oils and perfumes.

Olive oil spreads

There’s increasing recognition around the world that olive oil, as a key component of the so-called Mediterranean diet, is really good for you. The latest news is about its effect on ulcers. So obviously the traditional growing countries are trying to expand cultivation and production. But as this article points out, that’s not always so easy. Pity there’s nothing in the piece on varieties, though.
