Estimation of Dietary Intake - Lab Report Example

Nutrient content was estimated using software from the website, Nutriondata.com.1 Methods and results are as follows. A diary was kept for a 7-day period detailing all nutritional intake including snacks and meals on a daily basis. All portions were weighed and a volume in grams was obtained. Nutritional content was then determined using software that determined Fat, protein and carbohydrate content for each food. Percentage equivalents for daily Calcium(Ca) and Iron(Fe) were also obtained. Dietary intake was then into caloric value in KiloJules(KJ) using the following conversion factors: 1 gram Fat=9 KJ, 1 gram Protein=4 KJ, 1 gram Carbohydrate=4 KJ, Miscellaneous Sugars= 4 KJ2.

Total KiloJule energy readings were obtained for each day. Percent required Ca3 and A classmate was interviewed for the dietary intake of foods from the previous day. Care was taken not to be judgmental and all answers were recorded and converted into gram portions. A table of the portions was again analyzed using nutrient analysis software and Fat, protein, carbohydrate, and sugars content determined, along with percentages of Ca and Fe daily requirements. Total energy from daily diet was determine in KiloJules as in &-day weighed method.

A table was made for each day of dietary intake a. 3. Total Nitrogen and proteinThese three results were then used to determined energy parameters of the diet.Results7-day Weighed RecordA table was made for each day of dietary intake and Fat, Protein, carbohydrate analysis was made using Nutridata software and according to the weight of the portion recorded.
