BACKGROUND The Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA) for vitamin A are 1.7 and 2.4 μmol/d (500 and 700 μg retinol activity equivalents/d), respectively, for nonpregnant, nonlactating women aged >19 y. This intake is presumed to maintain a minimally acceptable liver concentration of 0.07 μmol (20 μg) retinol/g; however, liver reserves have not been evaluated...

The study provides original analytical data on the micronutrient profile of some traditional Italian hams, representative of the major ham categories produced in Italy: 4 dry-cured hams (Modena, Nazionale, Parma, San Daniele), 3 cooked hams (Cotto, Scelto, Alta Qualità), 1 smoked ham (Speck). Data on macronutrients (protein, lipid, moisture), energy, trace elements (Fe, Zn, Cu, Mn, Se), B vitam...

Menstrual blood loss was measured in 80 apparently healthy women aged 15-44 years. The study showed a median menstrual blood loss of 37.1 ml per period and the range was from 5.4-169.0 ml. With an average menstrual cycle of 29 days and a mean hemoglobin content of 12.8 g/dl the average iron loss was estimated to be about 0.55 mg/day. The simultaneous effects of menstrual iron loss and dietary i...

Skeletal muscle mass and function are progressively lost with age, a condition referred to as sarcopenia. By the age of 60, many older adults begin to be affected by muscle loss. There is a link between decreased muscle mass and strength and adverse health outcomes such as obesity, diabetes and cardiovascular disease. Data suggest that increasing dietary protein intake at meals may counterbalan...

The purpose of this study was: 1) to collect baseline data on nutrient intake in order to advise athletes about nutrition practices that might enhance performance, and 2) to evaluate the dietary iron intake and blood iron status of Japanese collegiate soccer players. The subjects were 31 soccer players and 15 controls. Dietary information was obtained with a food frequency questionnaire. The me...

BACKGROUND The more effective treatment for severe obesity is bariatric surgery. Gastric bypass is a surgical technique used worldwide; however, as well as other techniques; it has postoperative risks, including nutrient deficiency. AIM To determine the amounts of dietary iron, calcium, vitamin D and vitamin B12 ingested by patients of a public hospital one year after gastric bypass, and comp...

OBJECTIVE Breakfast has been linked to several aspects of health, yet breakfast skipping is rampant across the globe. Studies in India have focused mostly on children. Hence the present study examined breakfast behaviour across different age and gender groups. DESIGN Cross-sectional sample, purposive sampling. Nutrient intakes of the participants derived from 24 h dietary recall and 3 d break...

The objective of this study was to measure anthropometric and haemoglobin level and nutrient intake of expecting women in the third trimester of pregnancy and to relate the birth weight of neonates as outcome of pregnancy. A cross sectional study was performed in Zahedan City. Two hospitals situated in the city were selected based on their approval and cooperation. Five hundred healthy pregnant...

The current investigation examined the effect of variations in protein intake on Whole body protein turnover (WBPTO) at rest in endurance-trained males. Whole body protein turnover is influenced by both diet and exercise. Whether endurance athletes require more protein than the non-exerciser remains equivocal. Five male runners (21.3 +/- 0.3 years, 179 +/- 2 cm, 70.6 +/- 0.1 kg, 8.7% +/- 0.4% b...

A total of 905 human milk samples collected in all provinces of Poland, between 12 and 75 days of lactation, were analyzed for selenium concentration. The distribution of Se levels in milk between the provinces was narrow and varied from 8.81 to 11.58 ng/mL, with the mean value (+/- SD) of 10.24 +/- 2.82 ng/mL. The regions with lower levels of Se were in the central and eastern part of Poland; ...
