The "trophic level enrichment" between diet and body results in an overall increase in nitrogen isotopic values as the food chain is ascended. Quantifying the diet-body Δ(15) N spacing has proved difficult, particularly for humans. The value is usually assumed to be +3-5‰ in the archaeological literature. We report here the first (to our knowledge) data from humans on isotopically known diets, ...

Although dietary nutrient intake is often adequate, nutritional supplement use is common among elite athletes. However, high-dose supplements or the use of multiple supplements may exceed the recommended daily allowance (RDA) of particular nutrients or even result in a daily intake above tolerable upper limits (UL). The present case report presents nutritional intake data and supplement use of ...

BACKGROUND Plant seeds have gained interest for their health benefits due to their fatty acid content. The objective of this study was to determine the effects of dietary consumption of milled sesame/pumpkin/flax seed mixture on glycemic control, serum lipids, phospholipid fatty acid status, and inflammatory factors in patients on hemodialysis. METHODS Thirty patients with well nutrition stat...

Alkylresorcinols (AR) could be good biomarkers of consumption of fiber-rich cereal products. The aim of this study was to examine the relationship between plasma ARs or urinary AR metabolites and cereal fiber intake in women consuming their habitual diet. Twenty-five postmenopausal and 31 premenopausal women were recruited. The subjects included also vegetarians (n = 20) to obtain a broad range...

We assessed the effect of a diet high in leafy and green vegetables, fruit, and nuts on serum lipid risk factors for cardiovascular disease. Ten healthy volunteers (seven men and three women aged 33 +/- 4 years [mean +/- SEM]; body mass index, 23 +/- 1 kg/m2) consumed their habitual diet (control diet, 29% +/- 2% fat calories) and a diet consisting largely of leafy and other low-calorie vegetab...

OBJECTIVE To provide an independent evaluation of seven day weighed dietary records, which are currently accepted as the most accurate technique for assessing habitual dietary intake in studies investigating the links between diet and health. DESIGN Subjects who had previously participated in the Northern Ireland diet and health study were reselected by stratified random sampling to represent...

OBJECTIVES The present study examined the amount and relative contribution of calcium from the habitual diet among rural Thais. MATERIAL AND METHOD Calcium intake was assessed using 3-day food records and interviewer-administered quantitative food-frequency questionnaire, containing 73 food items. RESULTS The authors recruited 436 healthy participants (181 men and 255 women), between 20 and...

Background: An upward trend has been noted for the incidence of prostate cancer (PCa) in Vietnam, but information is limited on modifiable factors associated with this form of cancer. This case-control study was conducted to ascertain any relationship between habitual tea consumption and PCa risk. Materials and Methods: Two hundred and fifty-three incident patients with histologically confirmed...
