INTRODUCTION Brazil has been called a nation in nutrition transitional because of recent increases in the prevalence of obesity and related chronic diseases. With overweight conditions already prevalent among middle-income populations, there exists a need to identify factors that influence nutrition behavior within this group. OBJECTIVE To address this subject, a research study was implemente...

OBJECTIVES The present study aimed to assess dietary adequacy and quality among Inuvialuit alcohol consumers and non-consumers in the Northwest Territories (NWT), Canada. STUDY DESIGN Cross-sectional study. METHODS A validated quantitative food frequency questionnaire was administered to individuals (n = 216) of randomly selected households in 3 NWT communities to capture dietary intake and...

BACKGROUND The consumption of low quality foods is common in low socioeconomic areas; and according to epidemiological studies, the density of nutrients often proves the quality of diet. This study aimed to compare the density of macronutrients and micronutrients in various parts of Tehran. METHODS This was a cross-sectional study performed from September to December 2007 in all the 22 distri...

BACKGROUND Combinations of foods that provide suitable levels of nutrients and energy are required for optimum health. Currently, however, it is difficult to define numerically what are 'suitable levels'. OBJECTIVE To develop new metrics based on energy considerations-the Nutrient Balance Concept (NBC)-for assessing overall nutrition quality when combining foods and meals. METHOD The NBC wa...

Calcium is an essential nutrient during pregnancy and lactation. Calcium contributes to bone development in the fetus and neonate and is considered a critical nutrient. Physiological changes in calcium metabolism occur during pregnancy and lactation. Some women may lose some of their bone density during pregnancy and/or lactation, and then regain it after the cessation of lactation. Implication...

Anthropogenic nutrient inputs into native ecosystems cause fluctuations in resources that normally limit plant growth, which has important consequences for associated food webs. Such inputs from agricultural and urban habitats into nearby natural systems are increasing globally and can be highly variable, spanning the range from sporadic to continuous. Despite the global increase in anthropogen...

a four-year field experiment was conducted to understand the characters of nutrient accumulation and distribution in maize under different yield levels, so as to provide scientific guidance for effective utilization of mineral fertilizers, and eventually for high yield of spring maize. the grain yield, nutrient (nitrogen, phosphorous, potassium) accumulation and uptake efficiency were evaluated...
