b a ckground:  obesity is recognized as a major public-health problem, which has reached epidemic proportions, in both developed and developing countries. the purpose  of   this   survey  is   to   study  effects  of   gastric  bypass  surgery  at micronutrients and macronutrients intake on patients with morbid obesity. m et h o ds :   this quasi-experimental study was conducted on 21    patien...

Modest dietary restriction extends lifespan (LS) in a diverse range of taxa and typically has a larger effect in females than males. Traditionally, this has been attributed to a stronger trade-off between LS and reproduction in females than in males that is mediated by the intake of calories. Recent studies, however, suggest that it is the intake of specific nutrients that extends LS and mediat...

OBJECTIVES The present study investigated associations between income and intake of nutrients and food in adults (n = 11,063) from the fourth Korea National Health and Nutrition Examination Survey 2007-2009. METHODS To examine relationships between individual dietary intake and anthropometric measures and family income, multiple linear regression models were constructed for each outcome varia...

Dietary restriction extends lifespan in a variety of organisms, but the key nutritional components driving this process and how they interact remain uncertain. In Drosophila, while a substantial body of research suggests that protein is the major dietary component affecting longevity, recent studies claim that carbohydrates also play a central role. To clarify how nutritional factors influence ...

BACKGROUND/OBJECTIVES The incidence of thyroid cancer has increased in many countries, including Korea. International differences in the incidence of thyroid cancer may indicate a role of diet, but findings from previous studies are inconclusive. Therefore, we aimed to investigate the roles of nutrients in thyroid cancer risk in Korean women. SUBJECTS/METHODS We conducted a case-control study...

BACKGROUND A simplified optically readable food record (ORFR) was developed and compared with an open-ended weighed record (WR). OBJECTIVE To compare intake of nutrients and foods using a seven-day ORFR with intake estimated using a seven-day WR. The results from each method were validated against 24-h urinary nitrogen excretion and energy intake (EI)/estimated basal metabolic rate (BMR) cut-...

BACKGROUND: The ratio of protein to carbohydrate (P:C) consumed influences reproduction and lifespan, outcomes that are often maximized by different P:C intake. OBJECTIVE: Determine if reproduction in female Drosophila drives elevated P:C intake. Distinguish whether such a preference is driven by egg production or from male-derived sex peptides in seminal fluid. METHODS: Intake of protein and c...

BACKGROUND Gestational weight gain (GWG) above the recently recommended ranges is likely to be related to adverse pregnancy outcomes and therefore a challenge in industrialized countries. AIMS We conducted a systematic review on observational studies in order to gain more evidence on whether diets with lower caloric/protein content or other diets might be associated with lower GWG. METHODS ...

BACKGROUND Breakfast is considered the most important meal of the day, yet many people skip breakfast. Studies indicate that school age children who regularly skip breakfast are not likely to concentrate in class, thus affecting school performance. This study determined the breakfast habits and nutrient contributions of the breakfast meal to the days' nutrient intake. DESIGN A cross sectional...
