The health effects of zinc and iron deficiencies can be devastating, particularly in developing countries. One strategy for addressing this problem involves fertilizing crops with the micronutrients. But no one has yet figured out whether these added nutrients end up in food products made with the fortified crops. Now researchers report in ACS' Journal of Agricultural and Food Chemistry that this type of biofortification can boost micronutrients in bread, but other factors are also important.
Harvests from freshwater fisheries such as the Great Lakes could total more than 12 million tons a year globally and contribute more to global food supplies and economies than previous estimates indicate, according to a study published today by Michigan State University and the US Geological Survey.
But the woodrats' unique adaptation that allows them to break down creosote toxins may be in jeopardy if temperatures continue to rise, according to University of Utah researchers. Their new study in Molecular Ecology explains why: Livers of mammals (including us) may be less efficient at breaking down toxins at higher temperatures.
Kansas State University researchers published a study in Frontiers in Environmental Science that showed Manganese relates differently than its cancer-causing cousin, arsenic, to dissolved organic matter in groundwater. Researchers say more studies are need to understand the relationship.
Researchers from the University of Zaragoza (Spain) have analyzed drinking water and detected oocysts of Cryptosporidium and cysts of Giardia, two protozoa that cause outbreaks of diarrhea in humans. The levels detected are very low and do not represent a health risk; however, according to the study, the ubiquity of these parasites and the inefficiency of conventional water treatment in reducing them may present a public health issue.
A comprehensive program to reduce or prevent childhood obesity in low-income communities led to significant improvements in obesity-related measures among children cared for at a Massachusetts community health center.
A large-scale effort to reduce childhood obesity in two low-income Massachusetts communities resulted in some modest improvements among schoolchildren over a relatively short period of time, suggesting that such a comprehensive approach holds promise for the future, according to a new study from Harvard T.H. Chan School of Public Health.
Researchers in China have developed a genetic engineering approach capable of delivering many genes at once and used it to make rice endosperm -- seed tissue that provides nutrients to the developing plant embryo -- produce high levels of antioxidant-boosting pigments called anthocyanins. The resulting purple endosperm rice holds potential for decreasing the risk of certain cancers, cardiovascular disease, diabetes, and other chronic disorders. The work appears June 27 in the journal Molecular Plant.
Just as people endlessly calculate how to upsize or downsize, bacteria continually adjust their volume (their stuff) to fit inside their membrane (their space). But what limits their expansion? The answer will suprise you.
Individuals who do not produce enough iron are anemic, and often experience fatigue. One common remedy is for physicians to prescribe an iron infusion to their anemic patients. This makes sense, but can lead to unexpected consequences like increasing the risk of food poisons such as Salmonella. These types of poisons depend on abundant access to iron. Physicians should be attuned to this dynamic when determining the strength of iron infusions for their anemic patients.
