1.4 Assessing key methods to measure nutritional status of chosen examples of food

As per the given case study, there are various kinds of methods to measure nutritional status of different types of food such as milk, butter, green leafy vegetables, beans and peas etc. Some techniques are as follows.

Anthropometric assessment: It is used to identifying a human being nutritional status. In this context, the height and weight of children and infants has measured. The effect of all types of food such as milk, butter, yogurt etc on the growth and development of the body of 8 to 18 years old ages girls.

Body Mass index: It defines the weight of a person in the against of his hight. As per the give case, for determining the BMI, the weight of the girls have measured in the respect of their height. The result has reflected the fat stores in body.

24 hours recall: In this process, a trained interviewer has asked some questions to recall and define every food and drinking item which has consumed during 24 hours by girls. With the help of this, it can be easy to determine the required average intake for girls i.e. 8 to 18 years old ages (Mehdi and et.al., 2013).

Weighted inventory: It is a most common technique in which a records of all types of drinks and food which has been consumed by a person has maintained. With the use of it, it can be easy to keep the records of average consumption of food of girls which help in future to determine the required nutritional values for further ages (Mitchell, 2012).

National food survey: It is a major food survey in UK which aim is to collect comprehensive cross sectional information about dietary habits as well as nutritional level of people of UK. In the context of 8 to 18 year old ages girls of school, a survey can be conducted. This framework has identified the nutrition intakes which has analysed from dietary records. Along with this, urine and blood sample, physical activity and measurement can be used for analyse nutritional status of girls (Rubatzky and Yamaguchi, 2012).
