background: residents of the northeastern region of iran experience high mortality rates from esophageal squamous cell carcinoma (escc). one etiologic factor might be exposure to high levels of polycyclic aromatic hydrocarbons, including benzo(|î±|)pyrene (bî±p). we examined whether food or water are the major sources of bî±p exposure in this population. materials and methods: we used a dietary...

Prices affect food purchase decisions, particularly in lower-income communities, where access to a range of food retailers (including supermarkets) is limited. The aim of this study was to examine differences in staple food pricing between small urban food stores and the closest supermarkets, as well as whether pricing differentials varied based on proximity between small stores and larger reta...

More than half the world’s population suffers from micronutrient malnutrition. Biofortification of staple food crops is a new public health approach to control vitamin A, iron, and zinc deficiencies in poor countries. Biofortification is the development of micronutrient‐dense staple crops using traditional breeding practices and modern biotechnology. It has multiple advantages: it capitalizes o...

Ferritin-iron has been shown to be as bioavailable as ferrous sulfate in humans. Thus, biofortification to breed crops with high ferritin content is a promising strategy to alleviate the global iron deficiency problem. Although ferritin is present in all food crops, its concentration varies between species and varieties. Therefore, a successful ferritin biofortification strategy requires a meth...

Executive Summary 1. Maize has been the recognised staple food for most Zambians in rural and urban areas. Food security policies and strategies in Zambia have therefore, remained highly biased towards maize. The danger of over-depending on maize is that its production is expensive and reliance on it alone narrows the food base, and also makes the national food security system vulnerable to dro...

OBJECTIVE To test Koctürk's model of dietary change among South-Asian Surinamese in the Netherlands. The model categorizes foods into staple, complementary and accessory foods and postulates that dietary change after migration begins with accessory foods while foods associated with ethnic identity (staple foods) change at a slower rate. DESIGN Cross-sectional data from the HELIUS study. Dieta...

Wheat, the "Staff of Life", has been an essential commodity to human existence through the centuries and is currently the most widely consumed staple food (Bagriansky, 2002). As versatile as they are nutritious, wheat products have graced tables in all continents. The range of forms this staple food takes is correspondingly varied: crusty French bread, soft Mexican tortillas and spicy Indonesia...
