OBJECTIVE To assess the relationship between feeding pattern and body mass index in free-living humans. DESIGN AND SUBJECTS Feeding pattern was assessed from 220 7-day weighed dietary records. 187 records were obtained from three separate existing studies, and reanalysed. These studies contained data on three age groups in the British population; Elderly(More)
Single-dose oral administration of 100 mg caffeine increased the resting metabolic rate of both lean and postobese human volunteers by 3-4% (p less than 0.02) over 150 min and improved the defective diet-induced thermogenesis observed in the postobese subjects. Measurements of energy expenditure (EE) in a room respirometer indicate that repeated caffeine(More)
OBJECTIVES To assess meals versus snacks in terms of their contribution to total daily energy intake (TDI), macronutrient composition, and food commodity profile. DESIGN AND SUBJECTS Meals and snacks were assessed from 220 7-day weighed dietary records. 187 records were obtained from three separate existing studies, and reanalysed. These studies contained(More)
One hundred and seventy-two 0.5-3.0-year-old children in a mountainous area of northern Hebei Province of China were randomly assigned to a vitamin A supplementation group (n = 98) or a control group (n = 74) for a 1 year double-blind study. Capsules containing 200,000 IU vitamin A and 40 IU vitamin E were given to the children in the experimental group 3(More)
BACKGROUND AND AIMS During the long-term treatment of patients with hereditary haemochromatosis (HH) the authors observed that proton pump inhibitors (PPI) reduced the requirement for maintenance phlebotomy. Gastric acid plays a crucial role in non-haem iron absorption and the authors performed a case review and intervention study to investigate if(More)
This article is a summary of the publication "Iron and Health" by the Scientific Advisory Committee on Nutrition (SACN) to the U.K. Government (2010), which reviews the dietary intake of iron and the impact of different dietary patterns on the nutritional and health status of the U.K. population. It concludes that several uncertainties make it difficult to(More)
In view of the high prevalence of edentulousness in developed countries, the evidence is reviewed for the effects of tooth loss on nutrition and health in the following categories of effects: mortality; food choice and nutrient intake; gastrointestinal irritation; digestion and nutrient absorption; nutritional status. The evidence indicates reduced(More)
The UK Food Standards Agency convened a group of expert scientists to review current research investigating factors affecting iron status and the bioavailability of dietary iron. Results presented at the workshop show menstrual blood loss to be the major determinant of body iron stores in premenopausal women. In the presence of abundant and varied food(More)
Daily metabolic rates of 16 post-obese women and 16 matched, lean controls were measured at three different levels of activity in a room respirometer. Both groups had similar height, weight, age, and other anthropometric indices. Results show that the post-obese have metabolic rates approximately 15% lower than their controls at any level of activity. They(More)
Oxidative damage to DNA in human tissues can be determined by measuring multiple products of oxidative damage to the purine and pyrimidine bases using gas chromatography-mass spectrometry (GC-MS). Oxidative damage to lipids (lipid peroxidation) can be quantitated by the mass spectrometry-based determination of F2-isoprostanes, specific end-products of the(More)
