OBJECTIVE To compare specific nutrient intake between normospermic and oligoasthenoteratospermic patients attending infertility clinics in two Mediterranean provinces of Spain. DESIGN Case-control study. SETTING Private fertility clinics in southeastern Spain. PATIENT(S) Thirty men with poor semen quality (case subjects) and 31 normospermic control subjects of couples attending our fertil...

The present study examined the dietary intakes of a population of pregnant women living in the North of England. The objectives of the paper were to assess and describe the dietary intakes of the population and relate the findings to existing data on the diet of pregnant and non-pregnant women in the UK. A total of 250 pregnant women attending their first antenatal appointment at the Jessop Win...

OBJECTIVE To compare the key differences between school lunches and packed lunches as consumed in a nationally representative sample of primary schools, 6-8 months after the nutrient-based standards for school lunch became mandatory. DESIGN Data on 6580 pupils' school lunches and 3422 pupils' packed lunches were collected between February and April 2009 from pupils attending primary schools i...

We have developed a thirty-nine-item semi-quantitative food-frequency questionnaire (FFQ) to assess the dietary consumption of 11,746 men and women in a prospective cohort study that evaluates the health effects of As from drinking water in Bangladesh. In order to validate the FFQ, two 7 d food diaries (FD) were completed for 189 randomly selected cohort participants in two different seasons of...

Protein food intake appears to partially structure dietary patterns, as most current emergent diets (e.g., vegetarian and flexitarian) can be described according to their levels of specific protein sources. However, few data are available on dietary protein patterns in the general population and their association with nutrient adequacy. Based on protein food intake data concerning 1678 adults f...

PURPOSE The aim of this study was to determine the energy and nutrient content of the served food, the actual energy and nutrient intake and the nutritional status of elderly residents in a nursing home. METHODS The nutritional status of 23 individuals aged 69 to 89 years with dementia were assessed by Mini Nutrition Assessment -test (MNA). The nutrient content of the served food was calculat...

Self-reported dietary intake is assessed by methods of real-time recording (food diaries and the duplicate portion method) and methods of recall (dietary histories, food frequency questionnaires, and 24-hour dietary recalls). Being less labor intensive, recall methods are more frequently employed in nutritional epidemiological investigations. However, sources of error, which include the partici...

The measurement of habitual food and energy intake in man is one of the hardest tasks a physiologist can undertake. There are three basic problems: firstly, the accurate determination of the subject’s customary intake; secondly, the conversion of this information to energy and nutrient intakes; and, thirdly, the length of time food intake should be measured before the information obtained can b...

In assessing food intake patterns in groups of individuals, it is usually important to know how many of these individuals present nutrient intakes above or below a determined criterion. This information is relevant for planning healthcare actions, both in monitoring and in assessing such interventions, and also for the purposes of regulating commercial activities. This paper discusses a new met...

The effect of improved food composition data on nutrient intake estimates was determined by re-analyzing dietary intake data from the Continuing Survey of Food Intake by Individuals (CSFII) 1994–1996, 1998 with the multi-year version of the Food and Nutrient Database for Dietary Studies (FNDDS) 1.0, wherein only the data improvements such as those due to new analytical data replaced the older v...
