Food groups, teeth & keeping healthy

Answers and reasoning. Review before teaching.

1. What is the healthiest drink for quenching thirst throughout the day without adding sugar to your teeth: plain water or fizzy soda?
Plain water
Water hydrates every cell in the body without sugar or acid that can harm tooth enamel.
2. Which hard framework inside your body supports your weight, gives your body its shape and protects vital organs like the brain and heart: the skeleton (bones) or the skin?
The skeleton (bones)
The human skeleton supports the body, protects organs and works with muscles to allow movement.
3. Which vitamin found in oranges, lemons, guavas, berries and peppers helps wounds heal and keeps gums healthy: Vitamin C or iron?
Vitamin C
Sailors historically ate citrus fruit rich in Vitamin C to prevent scurvy.
4. What happens to your heart rate and breathing rate when you run, swim or play sport: both your heart rate and breathing rate speed up to deliver more oxygen and glucose to working muscles, or they slow down to zero?
Both your heart rate and breathing rate speed up to deliver more oxygen and glucose to working muscles
Active muscles respire faster and need a faster supply of oxygenated blood.
5. What is the hardest substance in the human body, which forms the protective outer coating of each tooth: tooth enamel or fingernails?
Tooth enamel
Enamel is a mineralised layer covering the crown of each tooth.
6. What is the first set of 20 temporary teeth that young children grow before their adult teeth come through: milk teeth (baby/deciduous teeth) or wisdom teeth?
Milk teeth (baby/deciduous teeth)
Children’s milk teeth gradually fall out from around age 6 to make room for 32 permanent adult teeth.
7. Which group of foods—including rice, bread, pasta, oats and potatoes—is our body’s main source of everyday energy: carbohydrates or table salt?
Carbohydrates
Starchy carbohydrates break down into glucose to fuel our muscles and brain.
8. Which nutrient—found in fish, eggs, beans, lentils, chicken and nuts—helps our bodies build and repair muscles and grow: protein or water?
Protein
Proteins supply amino acids needed to grow and repair body tissues.
9. Why is washing your hands with soap and clean water for 20 seconds before eating and after using the toilet so important: soap removes and breaks down microscopic germs (bacteria and viruses) so they cannot make you ill, or soap makes hands sticky?
Soap removes and breaks down microscopic germs (bacteria and viruses) so they cannot make you ill
Handwashing is the single most effective everyday habit for preventing the spread of infections.
10. Why do children and teenagers need a good night’s sleep every night: the brain consolidates learning and memory while the body repairs tissues and releases growth hormone, or sleep wastes energy?
The brain consolidates learning and memory while the body repairs tissues and releases growth hormone
Adequate sleep is essential for concentration, immune health and physical growth.
11. Why does the body sweat when you exercise on a warm day: as sweat evaporates from the skin, it carries away heat energy and cools the body down, or sweat warms the skin?
As sweat evaporates from the skin, it carries away heat energy and cools the body down
Evaporative cooling helps keep core body temperature near 37 °C.
12. Which mineral found in milk, yoghurt, cheese, tofu and leafy greens helps build strong bones and teeth: calcium or helium?
Calcium
Calcium gives bones and tooth enamel their strength and hardness.
