In comparison to European Union markets, where bans and protests have limited availability, genetically modified (GM) foods have entered United States supermarkets with little public opposition. This study compared attitudes towards GM foods in San Francisco versus Swedish consumers to determine if a difference exists. Previous studies have concluded that a difference exists although no study h...

OBJECTIVE To assess the status of food security--i.e., access to food, food availability and food utilization--in South Africa. METHODS A systematic search of national surveys that used the Community Childhood Hunger Identification Project (CCHIP) index to measure food security in South Africa over a period of 10 years (1999-2008) was conducted. Anthropometric data for children aged 1-9 years...

Food security is concerned with the food supply. Nutrition status, however, depends not only on suitable food but also on good basic health services and, particularly for children and the elderly, adequate care. Malnutrition generally results not from a lack of food in the community (limited availability) but from the skewed distribution of the food that is available. The skew results mainly be...

The oral bioavailability of many hydrophobic bioactive compounds found in natural food products (such as vitamins and nutraceuticals in fruits and vegetables) is relatively low due to their low bioaccessibility, chemical instability, or poor absorption. Most previous research has therefore focused on the design of delivery systems to incorporate isolated bioactive compounds into food products. ...

AIMS To systematically review the literature on daily losses and bioavailability of vitamin B12. These estimates could be used for deriving recommendations on vitamin B12 intake for adults and elderly. METHODS We identified publications on daily vitamin B12 losses (July 2011) and publications on the bioavailability of vitamin B12 from foods or diets (June 2010) in MEDLINE, EMBASE and the Coch...

Southeast Asia's lowland dipterocarp forests experience supra-annual "mast" fruiting and flowering events, in which the majority of trees reproduce simultaneously at irregular intervals, with extensive intervening periods of very low primate food availability. This scarcity of food results in a negative energy balance and a reliance on "fallback foods" in some primate species. By contrast, ombr...
