Dietary patterns are comprehensive variables of dietary intake appropriate to model the complex exposure in nutritional research. The objectives of this study were to identify dietary patterns by applying two statistical methods, principal component analysis (PCA) and reduced rank regression (RRR), and to assess their ability to predict all-cause mortality. Motivated by previous studies we chos...

Nutrient administration following an exercise bout vastly affects anabolic processes within the human body, irrespective of exercise mode. Of particular importance are protein and carbohydrates whereby these two macronutrients portray distinct functions as anabolic agents. It has been confirmed that protein and/or amino acid ingestion following resistance training is required to reach a positiv...

Background: The present study aimed to determine the mean blood glucose during the first 24 h post-surgery and its relation with the source of calorie intake.Methods: The data of the current observational retrospective study was collected from hospital medical records. A total of 45 neonates suffering from atresia in different parts of the gastrointestinal tract, who were candidates for o...

Objective: This study aimed at evaluating the balance in the intake of protein, carbohydrate, and fat among the Brazilian elderly population. Methods: The data analyzed were taken from the National Dietary Survey 2008-2009, from a total of 4,286 Brazilian elders (60-104 years old). Based on the dietary intake obtained from two food records, the Multiple Source Method (MSM) was used to evaluat...

OBJECTIVE We assessed whether the association between dietary saturated fatty acids (SFA) and incident coronary heart disease (CHD) depends on the food source, the carbon chain length of SFA, and the substituting macronutrient. APPROACH AND RESULTS From the Rotterdam Study, 4722 men and women (≥55 years) were included. Baseline (1990-1993) SFA intake was assessed using a validated food freque...

We evaluated the validity and reproducibility of the FFQ used in the Shanghai Men's Health Study (SMHS). The study included 195 randomly selected participants of the SMHS who completed one FFQ at baseline, twelve 24-hour dietary recalls (24-HDR) (once a month for twelve consecutive months) and a second FFQ at the end of the study. The FFQ accounted for 88.78% of the foods recorded in the 24-HDR...

This study aimed to diagnose the nutritional status of the Weight Lifting Permanent Olympic Team Athletes of the Brazilian Olympic Committee (COB). The sample was composed of 24 athletes, aged 16-23 yr, 12 males (19.7 ± 2.4 yr) and 12 females (19.2 ± 1.8 yr). The following procedure was applied to diagnose the nutritional status: analysis of the adequability of energy and macronutrient intake –...

BACKGROUND poor physical capability is associated with higher subsequent risk of disability and mortality in older people. Energy and macronutrient intakes may play a role in the maintenance of physical capability. This analysis aimed to examine the role of intakes of energy and the macronutrients, protein, carbohydrate and fat in early and mid-adulthood on objective measures of physical capabi...

Calorie restriction (CR), which usually refers to a 20-40% reduction in calorie intake, can effectively prolong lifespan preventing most age-associated diseases in several species. However, recent data from both human and nonhumans point to the ratio of macronutrients rather than the caloric intake as a major regulator of both lifespan and health-span. In addition, specific components of the di...

Rats increase their intake of food, but not water, after intraperitoneal injection of MK-801, a noncompetitive antagonist of N-methyl-D-aspartate-activated ion channels. We hypothesized that MK-801 might enhance intake by interfering with intestinal chemosensory signals. To test this hypothesis, we examined the effect of the antagonist on 15% sucrose intake after an intraduodenal infusion of ma...
