OBJECTIVE To determine the relationship between nutritional status and dietary intake in patients with cystic fibrosis. METHODS Cross-sectional study involving 85 cystic fibrosis patients between 6 and 18 years of age. Dietary intake was evaluated by the 3-day diet record (weighing the food consumed). The outcome measures were the following nutritional status indicators: weight/height (W/H%) ...

CONTEXT Nutrition education aims to enhance knowledge and improve dietary intake in athletes. Understanding athletes' nutrition knowledge and its influence on dietary intake will inform nutrition-education programs in this population. PURPOSE To systematically review the level of nutrition knowledge in athletes, benchmark this against nonathlete comparison groups, and determine the impact of ...

OBJECTIVE The insulin-like growth factor (IGF) system has been implicated in the aetiopathogenesis of cancer, cardiovascular disease and diabetes. Since dietary factors and ethnicity are considered contributory to the development of these diseases, we examined the IGF system in relation to nutritional intake by ethnic group. DESIGN, SUBJECTS AND SETTING Dietary intake in 257 subjects of White...

Guidelines have recommended significant reductions in dietary sodium intake to improve cardiovascular health. However, these dietary sodium intake recommendations have been questioned as emerging evidence has shown that there is a higher risk of cardiovascular disease with a low sodium diet, including in individuals with type 2 diabetes. This may be related to the other pleotropic effects of di...

BACKGROUND We have recently shown that biomarker levels of selected metals are higher in Asians than in other U.S. ethnic groups, with important differences within selected Asian subgroups. Much of this difference may be dietary in origin; however, this is not well established. OBJECTIVE We evaluated dietary intake of toxic metals as a source of increased biomarker levels of metals among U.S....

BACKGROUND & AIMS Lower birth weight is associated with an increased risk of cardiovascular and metabolic disease. These associations may, at least in part, be explained by alterations in dietary intake in later life. The aim of this study is to examine whether lower birth weight is associated with alterations in dietary intake in later life, and whether this association is due to intrauterine ...

 Background: Oxidative stress is detrimental to semen quality and has a significant role in the etiology of male subfertility. Methods: Dietary intake of antioxidants were compared between thirty two men with oligolastheno/ teratazoospermic (cases) and 32 normospermic volunteers (controls) attending fertility clinic in Mirza Koochak-khan Hospital in Tehran, Iran. All participants were...

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...

BACKGROUND AND PURPOSE An inverse relationship of dietary potassium to stroke mortality in a small community has been previously reported. To further assess this association in a larger sample, we examined data from the first National Health and Nutrition Examination Survey (NHANES I) Epidemiological Follow-up Study. METHODS We analyzed baseline data during 1971-1975 and follow-up through 199...
