Olympiad Test: Food, Health, And Sanitation -2 - Class 4 MCQ

Health means more than just not being sick. It includes:

• Physical well-being – feeling good in your body
• Mental well-being – having a good state of mind
• Social well-being – being happy with friends and family

So, to be truly healthy, you need to be well in all these areas!

To stay healthy, we need to eat a balanced diet. This means we should include a variety of foods in our meals, such as:

• Fruits and vegetables
• Whole grains like rice and bread
• Proteins from meat, fish, eggs, or beans
• Dairy products like milk and cheese

Eating too much fast food or just one type of food, like only eggs or only green vegetables, is not healthy. A mix of different foods helps our bodies get all the nutrients we need to grow and stay strong.

Personal hygiene is very important for staying healthy. Here are some key points about it:

• Regular handwashing helps prevent germs from spreading.
• Bathing regularly keeps our body clean and fresh.
• Using public toilets can be risky if not cleaned properly, so it's better to wash hands after using them.
• Exercising daily is good for health but is not a part of personal hygiene.

Therefore, the best example of personal hygiene is regular handwashing and bathing.

Regular exercise provides several important benefits for our health:

• Helps maintain a healthy weight.
• Reduces stress and makes you feel happier.
• Improves your heart and lung health.
• Strengthens your muscles and bones.

Staying active is fun and keeps your body strong!

Sanitation is very important for our health and well-being. Here are the main points:

• Safe disposal of human waste helps prevent diseases.
• Keeping our surroundings clean is essential for a healthy environment.
• Sanitation helps eliminate infectious diseases that can spread easily.

By focusing on these areas, we can ensure a healthier community for everyone.

The loss of extra water and salt from the body happens when we do not drink enough fluids. This condition is known as dehydration. Here are some important points to understand:

• Dehydration can make you feel tired and weak.
• It is important to drink enough water to stay healthy.
• Signs of dehydration include feeling thirsty, dry mouth, and dark urine.
• You can prevent dehydration by drinking water regularly, especially in hot weather.

Answer:
The disease caused by unclean surroundings and bad food habits is Diarrhoea.

By recycling, we can:

• Control pollution by reducing waste.
• Save natural resources like trees and minerals.
• Create useful things from materials we no longer need.

All these benefits show how important recycling is!

One main cause of disease that is not infectious is pollution. Here's why:

• Pollution can harm our health without spreading like germs.
• It includes dirty air, water, and soil.
• Unlike bacteria, fungi, and viruses, which can infect people, pollution is a result of human actions.

Therefore, pollution is a significant non-infectious cause of disease.

To keep ourselves safe from diseases, it is important to dispose of sewage properly. The best way to do this is through a:

• Covered drainage system, which helps to keep the sewage contained and prevents bad smells.
• This system also stops harmful germs from spreading in our environment.
• Using a covered drainage system is safer than throwing sewage in places like dustbins or garbage dumps.
