A comparison of three different method for the estimation of dietary intake. Illustrate your essay with specific examples.
Energy intake surveys form an integral part of studies aimed at
assessing food security. In the present study three methods
especially the 24-hour recall method, the 7-day weighed dietary
record method and the duplicate diet method were performed and
evaluated for their efficiency to estimate the food intake as
accurately as possible. It was found that the duplicate diet method
was the best as it involved laboratory analysis of foods for
calculation of energy content rather than rely on established
tables and websites for the same. Also it was able to predict the
exact energy amount consumed which is a very important step in food
security survey to assess health.
The advent of different survey methods and software programs has
definitely our understanding of nutritional value of foods and also
the amount of intake needed to maintain a healthy pattern of life.
The three survey methods used in the present study definitely have
advantages and disadvantages. After assessing all the three methods
it is concluded that the duplicate diet method is the best with
respect to accuracy and limited bias.
