AI Article Synopsis
- Estimation of caloric intake is key in treatment for eating disorders at the National Institute of Mental Health, using daily food recordings and food composition tables.
- Comparison of these estimates with laboratory data over 15 days showed a 2.4% overall underestimation of daily caloric intake, with carbs and fats overestimated by 4.5% and 5.4%, respectively.
- The findings indicate that methods based on food exchange lists are reasonably accurate for patients in treatment, making them a viable option for estimating calorie intake.
Article Abstract
Estimation of caloric intake is an integral part of a comprehensive research/treatment program for patients with eating disorders at the National Institute of Mental Health. Caloric intakes are estimated by recording daily food intake and calculating calories using food exchange lists and food composition tables. To evaluate the validity of that method, caloric intake estimates were compared with laboratory analysis data over a 15-day period. The estimations for daily caloric intake in comparison with the laboratory analysis data were underestimated by a mean percent difference of 2.4%. The estimated carbohydrate and fat intakes were overestimated by 4.5% and 5.4%, respectively. The estimated protein intake was underestimated by 1.1%. The data suggest that estimates of caloric intake based on food exchange lists and food composition tables are within an acceptable range of error and, therefore, represent a practical approach to estimating caloric intake for patients hospitalized with an eating disorder.

Hand-rearing of marine mammals is an essential technique for the husbandry of orphans in captivity or the wild, especially endangered cetacean species. The purpose of the present study was to establish a method for successful hand-rearing and evaluate the nutritional state of neonatal finless porpoises. Two neonate finless porpoises maternally neglected at 5 days of age (Day 5) (neonate A, animal A) and Day 4 (neonate B, animal B) were hand reared.

Unlabelled: In very preterm-born infants, nutritional intake is important to reduce the risk of severe metabolic bone disease including the risk of a lower bone mineral density (BMD). The aim of this study was to evaluate bone mineral content (BMC) and BMD (measured as BMC per bone area (BA)) at six years of age in very preterm-born infants fed different diets post-discharge. Data on this topic so far is insufficient, and with this study we aim to supply more useful data.

Telomere length has been related to human health and ageing in multiple studies. However, these studies have analyzed a small set of variables, according to pre-formulated hypotheses. We used data from NHANES 1999-2002 to perform a preregistered cross-sectional analysis.

Rewards are rewarding owing to their hedonic or metabolic value. Individual differences in sensitivity to rewards are predictive of mental health problems but may reflect variation in metabolic types. We have assessed the association of two distinguishable aspects of reward sensitivity, openness to rewards (the striving towards multiple rewards) and insatiability by reward (the strong pursuit and fixation to a particular reward), with measures of metabolism and activity in a longitudinal study of representative birth cohort samples.

Background: Inadequate energy intake among athletes can lead to low energy availability (LEA) which in turn can result in negative effects on athletic performance and physical and psychological health. This syndrome is known as relative energy deficiency in sports (REDs).
Objective: To map perceived changes in overall food intake among adolescent athletes during the previous year, as well as weekly changes during a 3-month period and to examine how these changes are associated with mental health, physical load and sex.
