BACKGROUND Accurate assessment of diet in study populations is still a challenge. Some statistical strategies that use biomarkers of dietary intake attempt to compensate for the biasing effects of reporting errors. OBJECTIVE The objective was to correlate biomarkers of dietary intake with 2 direct measures of dietary intake. METHODS Subjects provided repeated 24-h dietary recalls and 2 food...

A previously described mathematical model of Zn absorption as a function of total daily dietary Zn and phytate was fitted to data from studies in which dietary Ca, Fe and protein were also measured. An analysis of regression residuals indicated statistically significant positive relationships between the residuals and Ca, Fe and protein, suggesting that the presence of any of these dietary comp...

background: migraine is defined as a chronic disabling condition which influences all physical, mental, and social dimensions of quality of life. some 12-15% of the world population suffers from migraine. the disease is more common among women. the onset, frequency, duration, and severity of migraine attacks may be affected by other predisposing factors including nutrition. therefore, determini...

background: we have previously reported multiple health benefits in individuals following the christian-based fasting protocol known as the daniel fast (df). however, our prior work has involved only short-term (21-day) assessments. for dietary modification to have a profound impact on health, compliance to the dietary plan must be established for the long-term. materials and methods we determi...

background: although several in vitro and animal studies have suggested that isoflavones might exert inhibitory effects on gastric carcinogenesis, epidemiologic studies have reported inconclusive results in this field. the aim of this brief review was to investigate whether such an association exists among dietary isoflavones and gastric cancer incidence, prevention, and mortality in epidemiolo...

conclusions the used protocol is not enough for treating vitamin d deficiency. furthermore, the protocol should be revised according to baseline vitamin d classification. results after initial evaluation, 116 cases were found to be deficient, and were divided into two equal groups of 58. no significant difference was found between the normal, treated and non-treated groups regarding age and gen...

agaricus bisporus and agaricus bitorquis are among most favorite mushrooms of the world. mineral contents, proximate composition and fatty acid profile of these mushrooms were determined for evaluation of their dietary value. na, k and li contents were high, while cr, cu, pb, co, zn, mn and ni concentrations were low in both agaricus bisporus and agaricus bitorquis. proximate analysis showed th...

The nutritional value of a high-carbohydrate diet was evaluated. Seven male marathon runners kept a food record diary for the three days preceeding two endurance races. They were instructed in how to compose a diet which contained about 9 g carbohydrate day-1 kg body weight-1. Sixty three per cent of the subjects' total energy intake was derived from carbohydrates. The dietary intake of vitamin...

Research into how protein restriction improves organismal health and lengthens lifespan has largely focused on cell-autonomous processes. In certain instances, however, nutrient effects on lifespan are independent of consumption, leading us to test the hypothesis that central, cell non-autonomous processes are important protein restriction regulators. We characterized a transient feeding prefer...
