Total Calories (total + calory)
Selected AbstractsExpenditure dispersion and dietary quality: evidence from CanadaHEALTH ECONOMICS, Issue 9 2008Timothy K. M. BeattyArticle first published online: 13 AUG 200 Abstract This paper examines links between the way in which a household spreads their food expenditure over time and the dietary quality of the food they purchase. I find that households who make more frequent, smaller food purchases buy healthier foods than households who make fewer, larger purchases. These households are more likely to purchase foods with a lower share of total calories from fats, saturated fats and a larger share of calories from fruits and vegetables. The analysis is extended using quantile regression. The effect of expenditure dispersion is found to be largest among households with poor diets i.e. those households with diets high in saturated fats and low in fruits and vegetables.

SEKER ABSTRACT In this study, shortening content in a wire-cut cookie formulation was reduced at 10, 20, 30 and 40% and replaced with apricot kernel flour (AKF). The effects of increased concentrations of AKF on the properties of cookies were investigated. Protein, fat and total dietary fiber (TDF) contents of the apricot kernels were determined as 21.8%, 40.2% and 35.8%, respectively, which confirmed that the apricot kernel is an important source of dietary protein as well as oil and fiber. Addition of AKF decreased the spread ratio and increased the hardness of the cookies (P , 0.01). However, sensory evaluation revealed that the cookies containing AKF were acceptable to the panelists at all concentrations (P , 0.01). TDF contents of the cookies increased significantly (P , 0.01) as the AKF supplemention increased. AKF is a suitable replacer of shortening in cookies at 10 and 20%. PRACTICAL APPLICATIONS Province of Malatya (Turkey) is one of the major apricot and apricot kernel producing regions in the world. Apricot kernels are generally exported and the importing countries use it especially in the production of oil, benzaldehyde, cosmetics, active carbon and aroma. Apricot kernels are also utilized in retail bakeries and consumed as appetizers. Cookies are one of the most popular bakery products and textural characteristics of cookies are highly influenced by their fat content. Health specialists recommend that daily fat consumption should not exceed 30% of the total calories in a diet. In this study, the preparation of apricot kernel flour (AKF), which does not require much processing and has the advantage of including other nutrients, was achieved. With the production of high-fiber and low-fat cookies by the usage of AKF, an exciting new potential as a food ingredient, especially in cereal products, is offered. [source] Time Course of Elevated Ethanol Intake in Adolescent Relative to Adult Rats Under Continuous, Voluntary-Access ConditionsALCOHOLISM, Issue 7 2007Courtney S. Vetter Background: Adolescence is a period of elevated alcohol consumption in humans as well as in animal models. Previous studies in our laboratory have shown that adolescent Sprague,Dawley rats consume approximately 2 times more ethanol on a gram per kilogram basis than adult animals in a 2-bottle choice free-access situation. The purpose of the present study was to examine the time course and pattern of elevated ethanol intake during adolescence and the adolescent-to-adult transition, contrast this intake with ontogenetic patterns of food and water intake, and determine whether adolescent access to ethanol elevates voluntary consumption of ethanol in adulthood. Methods: Adolescent [postnatal day (P)27,28] and adult (P69,70) male Sprague,Dawley rats were singly housed with continuous access to both water and 1 of 3 experimental solutions in ball-bearing,containing sipper tubes: unsweetened ethanol (10% v/v), sweetened ethanol (10% v/v+0.1% w/v saccharin), and saccharin alone (0.1% w/v). Results: Ethanol consumption plateaued at approximately 7.5 g/kg/d during the first 2 weeks of measurement (i.e., P28,39) in early adolescence, before declining sharply at approximately P40 to levels that were only modestly elevated compared with adult-typical consumption patterns that were reached by approximately P70. In contrast, intake of food and total calories showed a more gradual decline into adulthood with no distinguishable plateaus in early adolescence. When adolescent-initiated and adult-initiated animals were tested at the same chronological age in adulthood, animals drank similar amounts regardless of the age at which they were first given voluntary access to ethanol. Conclusions: Taken together, these data suggest that the elevated ethanol intake characteristic of early-to-mid adolescence is not simply a function of adolescent-typical hyperphagia or hyperdipsia, but instead may reflect age-related differences in neural substrates contributing to the rewarding or aversive effects of ethanol, as well as possible modulatory influences of ontogenetic differences in sensitivity to novelty or in ethanol pharmacokinetics. Voluntary home cage consumption of ethanol during adolescence, however, was not found to subsequently elevate ethanol drinking in adulthood. [source] Deficiencies in nutritional intake in patients admitted with diabetes-related foot complicationsNUTRITION & DIETETICS, Issue 3 2007Sarah PITT Abstract Aim:, Adequate nutritional intake is an essential component for timely wound healing. The present research aimed to identify the frequency of inadequate dietary intake, including the specific nutritional elements most frequently lacking, in a group of patients admitted with diabetes-related foot complications. Methods:, Consecutive patients admitted to a diabetic foot unit underwent a dietary assessment, which included the retrospective collection of a seven-day food history for the period just prior to admission. The collected data were entered into FoodWorks, and comparisons were made with recommendations made by national guidelines. Results:, Thirty-five patients underwent nutritional assessment, 74% male and 26% having impaired renal function. Protein consumption was in excess of daily recommended intake, and although the overall fat intake as a percentage of total calories consumed was in keeping with national guidelines, the intake of saturated fat was inappropriately high. Of the 12 micronutrients assessed, niacin and vitamin C were appropriately consumed by all; average intake of potassium, phosphorus and thiamine approached recommended levels, while the intake of magnesium, calcium, zinc, riboflavin, folate and vitamin A all fell short of recommended daily requirements. No dietary differences were identified between individuals with normal and abnormal renal function, but deficiencies in calcium and iron were identified only in women. Conclusion:, Dietary deficiencies of macronutrients were not identified in individuals admitted with diabetes-related foot complications, but many patients were found to be consuming well below the daily recommended daily intake of one or more of the micronutrients deemed necessary for normal wound healing. [source] Health Beliefs toward Cardiovascular Risk Reduction in Patients Admitted to Chest Pain Observation UnitsACADEMIC EMERGENCY MEDICINE, Issue 5 2009David A. Katz MD Abstract Objectives:, Even after acute coronary syndrome (ACS) is ruled out, observational studies have suggested that many patients with nonspecific chest pain have a high burden of cardiovascular risk factors (CRFs) and are at increased long-term risk of ischemic heart disease (IHD)-related mortality. The aim of this study was to evaluate the premise that evaluation in an observation unit for symptoms of possible ACS is a "teachable moment" with regard to modification of CRFs. Methods:, The authors conducted a baseline face-to-face interview and a 3-month telephone interview of 83 adult patients with at least one modifiable CRF who presented with symptoms of possible ACS to an academic medical center. Existing questionnaires were adapted to measure Health Belief Model (HBM) constructs for IHD. Stage of change and self-reported CRF-related behaviors (diet, exercise, and smoking) were assessed using previously validated measures. The paired t-test or signed rank test was used to compare baseline and 3-month measures of health behavior within the analysis sample. Results:, Of the 83 study patients, 45 and 40% reported having received clinician advice regarding diet and physical activity during the observation unit encounter, respectively; 69% of current smokers received advice to quit smoking. Patients reported lower susceptibility to IHD (13.3 vs. 14.0, p = 0.06) and greater perceived benefit of healthy lifestyles (27.5 vs. 26.4, p = 0.0003) at 3-month follow-up compared to baseline. Patients also reported greater readiness to change and improved self-reported behaviors at follow-up (vs. baseline): decreased intake of saturated fat (10.1% vs. 10.5% of total calories, p = 0.005), increased fruit and vegetable intake (4.0 servings/day vs. 3.6 servings/day, p = 0.01), and fewer cigarettes (13 vs. 18, p = 0.002). Conclusions:, Observed changes in IHD health beliefs and CRF-related behaviors during follow-up support the idea that observation unit admission is a teachable moment. Patients with modifiable risk factors may benefit from systematic interventions to deliver CRF-related counseling during observation unit evaluation. [source] | ||||||||||
