Greetings from Nairobi. I’m here for a week’s rest and relaxation, which does not of course preclude blogging! Anyway, what I wanted to write about has nothing to do with Kenya. Or at least I don’t think buckwheat — our subject this evening — is grown here. It all started a week back when I went up to Lucca, near Pisa, for the weekend. That included a lot of eating, of course, and one of the dishes that particularly struck me was a main course composed of a thin tortilla-type thing, folded up, and filled with a nice sauce. I can’t remember the name of the dish, but the tortilla was made of “grano Saraceno,” according to the menu. I hadn’t heard the name, but a little snooping confirmed it to be buckwheat. A rarish crop in Italy, but nevertheless the basis of some interesting traditional recipes. Now, I knew a little about buckwheat, but next to nothing about its nutritious relative, Tartar(y) buckwheat. And I certainly didn’t know that there’s an easily de-hulled variety of this crop called rice-tartary which promises to be a boon to breeders. Nor that you can emasculate the flowers with hot water, which could also be useful if you’re trying to make crosses. I should eat out more.
Nutrition news from the Antipodes
What do these fruits have in common: Kakadu plum, Illawarra plum, Burdekin plum, Davidson’s plum, riberry, red and yellow finger limes, Tasmanian pepper, brush cherry, Cedar Bay cherry, muntries and Molucca raspberry? Five points if you said “They’re all native Australian fruits”. Ten points if you said “According to this press release I just read, they’re exceptional sources of antioxidants identified in research published in the journal Innovative Food Science & Emerging Technologies”.
Ten points to me.
Tree domestication a huge success
There’s a heart-warming tale over at the Rural Poverty Portal (nice site, too) of the International Fund for Agricultural Development. A tree domestication project in west Africa has brought higher incomes and improved status for women, which has translated into schooling and better nutrition. Women are running their own tree nurseries, selecting which species to grow and nurturing them for market. So far the number of species is limited, perhaps that will improve. The project was implemented by the World Agroforestry Centre.
GI had no idea there was so much diversity
We know hardly anything about the differences among varieties of the same crop. Oh sure, we know what different varieties look like; that’s easy. But detailed differences in composition are hard to find. There are the classics, of course, like wetet be gunche sorghum in Ethiopia, whose name translates as “milk in my mouth”. It contains almost a third more protein than other sorghum varieties and, even more important, about double the level of lysine, a vital amino acid for human nutrition. And there are the red and black varieties of rice, which are known to be high in iron and other minerals and vitamins and which are traditionally used to treat anaemia, especially in pregnant women. (I have been unable to discover whether this treatment is effective, in a Western sense, but it seems entirely reasonable, and a bit churlish to deny it.) But in general, we know next to nothing about the nutritional qualities of varieties, as opposed to species.

Cow vs goat milk
We’ve blogged before about how goat’s milk is more digestible than cow’s milk, but makes cheese which is lower in beta carotene. Now it turns out that goat’s milk has “higher bioavailability of iron, calcium, phosphorus and magnesium.” Goat’s milk has about 2% of the market. ((In the UK.)) Got (goat’s) milk?
