Nutritional science - Assignment Example However, protein intake was 7% compare to the National Reference Value (NRV) of (15-25%) means less protein could cause serious health risks. The energy intake compared to expenditure reveals that intake was less than the population benchmark. This was attributed to by the medical condition the participant had known as lap band laparoscopy had only selective type of food. Generally the study concludes that most dietary assessment methods are limited by both bioavailability and natural variations in nutrients. Dietary assessment is the processes of evaluating nutrient intake by employing appropriate methods in order to identify the type of nutrients that are either under taken or overtaken by individual or a population. The appropriate method for dietary assessment is determined by the purpose and the target individuals. However, an appropriate dietary assessment must report all foods consumed by individuals including quantification, frequency and the nutrient content of each one (1). It is also important to note that quantification is very critical in assessment of nutrient intake and physical activity levels because of the need to compare individuals’ intakes of energy, macro and micronutrients with the recommended targets such as national reference values (NRV), Recommended Daily Intake (RDI), Estimated Average Requirement (EAR) and Acceptable Daily Intake (ADI). One of the best methods for assessing nutrient intake and physical activity is the Weighed Food Records. Weighed food record is a dietary assessment method that involves an individual taking actual weights of foods and drinks prior to their consumption (2). The records also contain details of eaten foods including full description and the time of consumption. The precise weight of food eaten is gotten by subtracting the left over from the original weights before consumption to improve on accuracy. High calorie foods have been
