An article in the February 2011 issue of Comprehensive Reviews in Food Science and Food Safety (CRFSFS) discussed how orange sweet potatoes could help prevent vitamin A deficiency in developing countries where this nutritional disease causes over 600,000 deaths per year--mostly of young children or pregnant women.
Most sweet potatoes in the United States are orange, but in developing countries sweet potatoes can also be white, cream, yellow and purple. According to the author, Betty J. Burri, of Western Human Nutrition Center at the United States Department of Agriculture, in these countries where vitamin A deficiency is common, it would help if the food industry could find ways to increase the production and consumption of orange-fleshed sweet potatoes.
Specifically, food companies could further this goal by developing improved varieties of prolific, hardy, disease and drought-resistant orange-fleshed sweet potatoes while developing and testing different food products made from sweet potatoes. For example, one of the sweet potato products that international programs are testing is sweet potato flour, which they can make into biscuits and buns.
There are many good sources of vitamin A and pro-vitamin A carotenoids in the American diet as well as access to orange sweet potatoes. However, in some parts of Africa the custom is to feed orange sweet potatoes to livestock and white sweet potatoes (which have very little pro-vitamin A carotenoids) to people. There are ongoing educational programs to guide these populations to eat more orange sweet potatoes and improve their vitamin A status. The food industry could help educate people about the types of sweet potatoes that are available, their nutrient content, and the best methods for storing, preparing, and cooking them.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
