Stop vitamin A supplements
The editorial by Thorne-Lyman and Fawzi in 2011, (1) referring to the meta-analysis of the impact of vitamin A supplements by Mayo-Wilson, Imdad and others, (2,3) has now become more important than ever. The DEVTA results, only informally available in 2011, have now been published, (4) with extensive implications; indeed, as the editorial (1) says: ‘… the null findings have left lingering questions. Is vitamin A supplementation effective?’. These results have been the subject of conflicting comments recently in the Lancet, e.g. (5,6). But a number of inferences that should be drawn from the compilation and analysis of the evidence from trials prior to DEVTA (2,3) help answer this lingering question, and have not received adequate attention. There are three key related points, which now point to the need to seriously consider concrete steps to move beyond 6-monthly vitamin A supplementation at unphysiological levels.
OK, there’s a lot in that introduction to a recent paper in the British Medical Journal to digest, but it is worth it. I know I bang on about the colossal boondoggle that is high-dose vitamin A supplementation, but there’s a reason. It seems to be a complete waste of money based on a very limited reading of the evidence. In 2011 the BMJ published an editorial on Improving child survival through vitamin A supplementation (which is behind a paywall) that referenced a meta-analysis of supplementation. The new paper — Is vitamin A supplementation effective? — brings things up to date with a more detailed analysis of some of the research only hinted at in the original articles. Bottom line: there is no evidence for large-scale effectiveness of vitamin A supplements on child mortality.
As the authors of the rebuttal ask, why are resources still going into supplementation campaigns of the old sort? And they conclude:
Improved diets, fortified foods, and multiple micronutrient provision would surely bring broader improvements in nutrition to more people, including reproductive aged women who are now largely excluded.
Nibbles: Frogs, Spuds, Apples, Cucumbers, Tosh?
- Take that, you cheese-eating surrender monkeys. England boasts oldest eaten anuran legs.
- Ban potatoes NOW! You know it makes sense.
- As American as industrially harvested, intellectually protected apples.
- Step aside Golden Rice; the Golden Cucumber is just over the horizon. That and much more from deep re-sequencing.
- Also just over the horizon, hordes of new, public domain banana varieties, although they don’t actually own the domain the video points to. Oops. h/t Bifurcated Carrots.

- On the other hand, why bother mimicking C4 when you could just reinvent photosynthesis?
- Speaking of C4, maybe less US maize will be turned into fuel next year.
- The “portal” to the diversity of bananas gets an update. But don’t go looking for plantains.
- Perennial grains still under discussion.
- The Right To Food and Nutrition Watch – a name to sow confusion – has made its 2013 articles available.
- Nutrition, these days, means adequate fibre, so of course the natural way to do that is to add citrus fibre to meatballs. Smacks forehead.
