The vast majority of American middle schools and high schools sell what are known as ‘‘competitive foods,’’ such as soft drinks, candy bars, and chips, to children. The relationship between consumption of sugar-sweetened drinks and snacks and childhood obesity is well established, but it remains unknown whether competitive food sales in schools are related to unhealthy weight gain among children.

Anaemia aff ects a quarter of the global population, including 293 million (47%) children younger than 5 years and
468 million (30%) non-pregnant women. In addition to anaemia’s adverse health consequences, the economic eff ect
of anaemia on human capital results in the loss of billions of dollars annually. In this paper, we review the
epidemiology, clinical assessment, pathophysiology, and consequences of anaemia in low-income and middleincome countries. Our analysis shows that anaemia is disproportionately concentrated in low socioeconomic groups,

Understanding the patterns of wild meat consumption from tropical forests is important for designing approaches to address this major threat to biodiversity and mitigate potential pathways for transmission of emerging diseases. Bushmeat consumption has been particularly poorly studied in Madagascar, one of the world's hottest biodiversity hotspots. Studying bushmeat consumption is challenging as many species are protected and researchers must consider the incentives faced by informants.

We all know we need to eat less meat – here are the hard numbers.
