Sample Questions
Why is jaggery considered nutritionally superior to refined white sugar, even though both are placed in the same food group?
Show answer
Jaggery contains iron which is important for the formation of Red Blood Cells, which refined sugar lacks
Step 1: Both jaggery and refined sugar belong to the 'Fats and Sugar' food group and primarily provide carbohydrates. Step 2: However, the chapter explicitly states: 'jaggery is better than sugar because jaggery contains iron.' Step 3: Iron is an essential mineral for the formation of Red Blood Cells (RBC) in our body. Deficiency of iron causes anaemia. Step 4: Refined white sugar is processed and loses most of its mineral content during refining, so it provides only empty calories (carbohydrates). Step 5: Option A is incorrect — both provide similar amounts of carbohydrates. Option C is wrong
Sarita's grandfather is 70 years old and has a slow digestive system. Which meal would be MOST appropriate for him from the perspective of the chapter's guidelines?
Show answer
Soft well-cooked khichri with steamed vegetables and curd
Step 1: The chapter discusses 'Age' as a key factor in meal planning. Step 2: For elderly (old) people, the chapter recommends: soft and easy-to-digest food in small quantity; soft and well-cooked high fibre meal. Step 3: Khichri is a soft, well-cooked dish made from rice (cereal) and dal (pulse) — it is easy to digest and provides complementary protein. Steamed vegetables add fibre and vitamins. Curd provides calcium and is easy to digest. Step 4: Option A is wrong — fried puri and gulab jamun are high-fat, hard-to-digest foods, inappropriate for elderly. Step 5: Option C may seem healthy but
Which of the following correctly explains why a rickshaw puller requires a different diet compared to a software engineer working in an air-conditioned office?
Show answer
The rickshaw puller requires more carbohydrates and proteins because physical labour demands more energy and muscle repair
Step 1: The chapter identifies 'Occupation' as a key factor affecting meal planning. Step 2: People who do heavy manual work — like labourers, rickshaw pullers, farmers, and sports persons — expend much more energy than those in sedentary occupations. Step 3: The chapter states: 'people like labourers, rickshaw pullers, sports persons and farmers do more manual work...so they require more carbohydrates and proteins.' Step 4: Carbohydrates provide energy for physical work, and proteins are needed for muscle repair after heavy physical activity. Step 5: Option A is a common misconception — vitam
A meal consists of: chapati, arhar dal, paneer curry, potato-beans sabji, and tomato salad. Using the five food group system, which food group is MISSING from this meal?
Show answer
Fats and sugar
Step 1: The five food groups are: (1) Cereals and grains, (2) Pulses and legumes, (3) Milk, egg and meat products, (4) Fruits and vegetables, (5) Fats and sugar. Step 2: Let us map each item — Chapati = Cereals (Group 1) ✓; Arhar dal = Pulses (Group 2) ✓; Paneer curry = Milk products (Group 3) ✓; Potato-beans sabji + tomato salad = Vegetables (Group 4) ✓. Step 3: After checking all five groups, Group 5 (Fats and sugar) has NO representative food item in this meal. Step 4: In a traditional Indian thali, oil or ghee used for cooking or a small amount of sugar/jaggery usually represents this grou
