Olympiad Test Level 2: Food - Class 3 MCQ

Energy-yielding foods are those that provide high amounts of energy.

• These foods are rich in carbohydrates and fats.
• Examples include cereals, roots, tubers, dried fruits, oils, and butter.

Protective foods are foods that are rich in essential vitamins and minerals, which help protect the body from diseases and maintain overall health.
Apple, Pineapple, and Orange are fruits high in vitamins (especially Vitamin C) and antioxidants, classifying them as protective foods.

(i) Peeling off an apple can reduce its nutritional value because the skin contains fiber and various nutrients. Therefore, this statement is true.
(ii) Carrots and radishes are not edible stems; they are edible roots. Therefore, this statement is false.
(iii) In lemonade, along with lemon juice, sugar and water are also present. Therefore, this statement is true.
Therefore, correct answer is C: T, F, T

The unscrambled words and their classification are:

Option A: ETWHAB → WHEAT: Wheat is an energy-giving food, not a body-building food.

Option B: TURIFSC → FRUITS: Fruits are protective foods, rich in vitamins and minerals, not body-building foods.

Option C: AIEMZD → MAIZE: Maize is also an energy-giving food, not body-building.

Option D: SLPUES → PULSES: Pulses (like lentils, beans, and chickpeas) are body-building foods because they are high in protein, which helps repair and build body tissues.
Therefore, correct answer is option D.

The category "Eaten Raw" includes foods that are commonly consumed without cooking. Let's analyze the options:

Option A: Potatoes and Mushrooms: Potatoes are usually cooked before consumption and are rarely eaten raw. Mushrooms are sometimes eaten raw but not always.

Option B: Carrot and Mushrooms: Carrots are commonly eaten raw, but mushrooms are not consistently a raw food item.

Option C: Eggplant and Potatoes: Both eggplant and potatoes are typically cooked before being consumed.

Option D: Carrot and Apple: Carrots and apples are widely known to be eaten raw in salads, snacks, or as part of a healthy diet.

Hence, the answer is D: Carrot and Apple, as both fit the category "Eaten Raw."

• Coconut oil: It is used for cooking food, but it is not a fuel. It is an ingredient in food preparation.
• Petrol: Petrol is used as fuel for vehicles, not for cooking.
• Diesel: Diesel is also used as fuel for vehicles or machines, not typically for cooking.
• Liquefied Petroleum Gas (LPG): LPG is the most common fuel used for cooking in homes and restaurants. It is stored in cylinders or supplied through pipelines. It burns cleanly and provides efficient heat for cooking food.

So, LPG is the correct answer because it is specifically designed and widely used as a cooking fuel.

She is not taking vitamins and minerals which are protective foods present in vegetables and fruits.

1. Cooking makes the food soft, tasty, and easy to chew and digest – This statement is CORRECT. Cooking breaks down tough fibers, enhances flavor, and makes food easier to consume and digest.

2. Reheating food again and again restores nutrients in the food – This statement is INCORRECT. Reheating food multiple times can actually destroy nutrients and may even make the food unhealthy to consume.

3. Eating junk food very often can lead to health problems – This statement is CORRECT. Junk food is often high in fats, sugars, and salt, which, if consumed frequently, can cause health issues like obesity, diabetes, and heart problems.

4. Old people need food that is hard and raw – This statement is INCORRECT. Older people usually require soft, easily digestible food due to weaker teeth and digestive systems.

Option A: Balanced diet keeps us fit and healthy – This statement is CORRECT. A balanced diet provides essential nutrients for the body to function properly, keeping us fit and healthy.

Option B: Overcooking decreases the nutritive value of food – This statement is CORRECT. Overcooking destroys essential nutrients like vitamins and minerals, reducing the food's nutritional value.

Thus, the incorrect statement is D.
