Describe the methods of diet survey. Add a note on consumption units.

1. 1 · Open in two lines. Diet surveys measure the food and nutrient intake of individuals or families to judge whether it meets their needs.
2. 2 · Name the methods.
   • 24-hour recall.
   • Food frequency questionnaire.
   • Weighment.
   • Diet history, food inventory, expenditure.
3. 3 · Draw the methods table. [Table: method, how it is done, merits, demerits]
4. 4 · Steps of a 24-hour recall. Standard measures, meal by meal, probing for forgotten items, conversion to raw amounts, nutrients from IFCT 2017.
5. 5 · Consumption units. Coefficients (sedentary man 1.0, sedentary woman 0.8, child of 3-5 years 0.5) and why they are needed.
6. 6 · Worked example. 3.3 CU family; 1320 g ÷ 3.3 = 400 g of cereals per CU per day.
7. 7 · In the community. Recall in every sampled home, weighment in a few; compare intake per CU with ICMR-NIN 2020 needs.
8. 8 · Close in one line. Choosing a method is a balance between accuracy, time and cost.

Scoring tip: A short CU sum inside the answer stands out. Show the total CU, the daily amount and the division on separate lines.
