Olympiad Test: Food And Health - 2 - Free MCQ with solutions Class 5 Science

Eating fruits and vegetables and milk as part of your regular diet is a healthy eating habit. These foods provide essential vitamins, minerals, and calcium needed for good health.

• Option A (Saumya sometimes eats cold spaghetti or leftover pizza for breakfast) is not ideal because pizza and spaghetti are not balanced or nutrient-rich breakfast options.
• Option C (Sumit skips breakfast when he is late for school) is not a healthy habit. Skipping meals can affect energy levels and overall nutrition.
• Option D (Anubhav counts fruit pie and sugared drinks as his daily fruit servings) is not a healthy practice. Fruit pies and sugary drinks are high in added sugars and do not provide the same nutritional benefits as whole fruits.

So, the correct answer is Option B: Ananya likes to eat a lot of fruits and vegetables along with milk.

Bread, jam, and potato chips are all rich in carbohydrates.

• Bread is made primarily from flour, which is a carbohydrate source.
• Jam contains sugar, which is a simple carbohydrate.
• Potato chips are made from potatoes, which are rich in starch, a complex carbohydrate.
• Option A (Rich in fat) is not accurate for all three items. While potato chips are high in fat, bread and jam are not primarily fat-rich.
• Option B (Rich in carbohydrate and protein) is not true for these foods; they are not good sources of protein.
• Option D (Rich in fiber) is not true either, as these foods are generally low in fiber.

So, the correct answer is Option C: Rich in carbohydrate.

Carbohydrates are primarily found in foods like starchy vegetables, grains, and sugar-rich plants.

• Potato, wheat, maize, and sugarcane are rich in starch, which is a complex carbohydrate that provides energy.
• Option A (Spinach, onion, ginger, tomato) contains fiber, vitamins, and minerals, but these are not significant sources of carbohydrates.
• Option C (Mango, papaya, orange, banana) are fruits that contain natural sugars (simple carbohydrates), but they don't have as much starch as the foods in Option B.
• Option D (Meat, fish, egg, pulses) is rich in protein and fats, not carbohydrates.

So, the correct answer is Option B: Potato, wheat, maize, sugarcane.

If a person eats too much food rich in fat and does no physical work, it leads to obesity. Obesity occurs when the body takes in more calories than it burns, leading to excess fat storage. This is often caused by overeating high-fat foods and lack of physical activity.

• Malnutrition (Option A) refers to a lack of proper nutrients, which can be caused by poor diet, but it's not directly linked to overeating fat.
• Vitamin deficiency (Option B) occurs when the body does not get enough vitamins, not typically from overeating fat.
• Night blindness (Option C) is a condition caused by a lack of vitamin A, not overeating fat.

So, the correct answer is Option D: Obesity.

Deficiency diseases occur when the body lacks essential nutrients over a long period. These diseases are caused by a lack of vitamins, minerals, or other important nutrients in the diet.

• For example:
  • Scurvy is caused by a lack of vitamin C.
  • Rickets is caused by a lack of vitamin D.
  • Anemia is caused by a lack of iron.
• Infectious diseases (Option A) are caused by infections from bacteria, viruses, or other pathogens, not by a lack of nutrients.
• Food lacking diseases (Option C) is not a standard term in medical terminology.
• Obesity (Option D) is related to overeating or an imbalance in energy intake and expenditure, not a nutrient deficiency.

So, the correct answer is Option B: Deficiency diseases.

Scurvy is a disease caused by a deficiency of vitamin C. The symptoms of scurvy include bleeding gums, swollen joints, weakness, and fatigue. This occurs because vitamin C is essential for collagen formation, which helps in maintaining the health of gums, joints, and blood vessels.

• Beri Beri (Option A) is caused by a deficiency of vitamin B1 (thiamine), leading to symptoms like weakness, numbness, and swelling.
• Rickets (Option B) is caused by a deficiency of vitamin D, leading to weak bones and deformities.
• PEM (Protein-Energy Malnutrition) (Option D) occurs due to an overall lack of protein and calories, leading to growth failure and other severe symptoms.

So, the correct answer is Option C: Scurvy.

Common cold is primarily spread through direct contact with an infected person or contaminated surfaces. The virus is spread when an infected person coughs, sneezes, or touches objects that others then touch, transferring the virus.

• Foul air (Option B) is not a common way for the common cold to spread.
• Houseflies (Option C) do not play a significant role in spreading the common cold.
• Dog-bite (Option D) is unrelated to the spread of the common cold.

So, the correct answer is Option A: Direct contact.

Calcium and phosphorus are essential minerals that are primarily required for the development and maintenance of healthy bones and teeth. They help in making bones strong and durable, and they also contribute to maintaining proper dental health.

• Blood (Option A) does require some minerals like iron, but calcium and phosphorus are not specifically needed for blood.
• Glowing skin (Option C) is generally influenced by vitamins like vitamin A and C, not calcium and phosphorus.
• Energy for playing (Option D) is mainly provided by carbohydrates and fats, not calcium and phosphorus.

So, the correct answer is Option B: Healthy bones and teeth.

A deficiency disease is a condition that occurs when the body does not receive enough of a specific nutrient, such as a vitamin or mineral, over a prolonged period. This can lead to various health problems, depending on which nutrient is lacking.

• Option B ("A disease caused by the lack of nutrients in food") refers to the general cause of deficiency diseases.
• Option C ("A disease which is caused due to deficiency or the lack of particular minerals or vitamins in the body") explains that these diseases are caused by the lack of specific nutrients like minerals or vitamins.

Thus, the correct answer is Option D: Both B and C.

A disease is a condition where the body does not function properly due to issues such as infections, deficiencies, or malfunctions in organs or systems. It can affect different parts of the body, including bones, but it isn't limited to bone problems.

• Option A ("When our bones do not function properly") only describes a specific issue related to bones, but diseases affect the body as a whole, not just one part.
• Option B is correct because diseases affect the normal functioning of the entire body, not just bones.
• Option C ("Both A and B") is incorrect because the disease is not only about bones not functioning but also about the entire body.
• Option D ("None of the above") is incorrect because Option B is the correct answer.

So, the correct answer is Option B: When our body does not function properly.

Vaccination is a medical process that involves:

• The injection of a substance into the body.
• Providing protection against specific diseases.
• Stimulating the immune system to recognise and fight infections.

Vaccines are crucial for preventing serious illnesses and safeguarding public health.

Vaccines are designed to protect us from specific diseases, but are not effective against all pathogens. They primarily target viruses and certain bacteria. However, vaccines do not provide protection against fungi.

Scurvy is a non-communicable disease caused by a deficiency of vitamin C (ascorbic acid) in the diet. It is not caused by bacteria, viruses, or any infectious agents, so it cannot be passed from one person to another.

• Option A ("Communicable disease") is incorrect because scurvy is not spread from person to person.
• Option C ("Infectious disease") is incorrect because scurvy is not caused by an infection but by a nutritional deficiency.
• Option D ("None of the above") is incorrect because Option B is the correct answer.

Thus, the correct answer is Option B: Non-communicable disease.

To stay healthy, it is important to eat a balanced diet that includes all the essential nutrients in the right proportions. A balanced diet provides carbohydrates, proteins, fats, vitamins, minerals, and water, all of which are necessary for the body to function properly and maintain good health.

• Option A ("All the nutrients") is incomplete because it doesn't mention the need for balance or the right proportions of nutrients.
• Option C ("Carbohydrates and proteins") is also incorrect because while carbohydrates and proteins are important, they are not enough on their own. A healthy diet needs a variety of nutrients, including fats, vitamins, and minerals.
• Option D ("Both A and C") is incorrect because the best answer is a balanced diet, not just focusing on specific nutrients.

So, the correct answer is Option B: Balanced diet.

Citrus fruits like oranges, lemons, and grapefruits are an excellent source of Vitamin C (ascorbic acid). Vitamin C is essential for the growth and repair of tissues in the body, helps heal wounds, and boosts the immune system.

• Option A ("A") refers to Vitamin A, which is mainly found in foods like carrots, sweet potatoes, and spinach.
• Option B ("B") refers to Vitamin B group, which includes several vitamins like B1 (thiamine), B2 (riboflavin), and B12 (cobalamin). These are found in foods like eggs, milk, and whole grains.
• Option C ("D") refers to Vitamin D, which is primarily found in foods like fish, eggs, and fortified dairy products.

So, the correct answer is Option D: C.
