Lesson Worksheet: Diet and Health Science

In this worksheet, we will practice defining health, describing the relationship between activity and energy requirements, and outlining examples of malnutrition caused by an unbalanced diet.

Q1:

The table shows the nutritional content of milk and its substitutes.

Nutrient Value per 100 cm3
Type of Drink Energy (kJ) Sugar (g) Fat (g) Protein (g) Calcium (mg)
Whole milk 273 4.6 3.7 3.5 124
Semi-skimmed milk 201 4.7 1.8 3.6 124
Skimmed milk 150 4.8 0.3 3.6 130
Soy milk 187 2.2 2.5 3.2 134
Almond milk 105 3.1 0.1 0.5 124

  • CSkimmed milk
  • DAlmond milk

Q2:

What type of nutrient is usually used by cells for the transfer of energy?

  • AMinerals
  • BProteins
  • CFibers
  • DVitamins
  • ECarbohydrates

What form of energy is food?

  • AKinetic energy
  • BThermal (heat) energy
  • CLight energy
  • DSound energy
  • EStored chemical energy

What process inside cells transfers energy from food into other forms for cell activities?

  • ADiffusion
  • BPhotosynthesis
  • CRespiration
  • DCombustion

Q3:

Which of the following health problems is most likely for a person suffering from obesity?

  • ADeficiency diseases
  • BWeak immune system
  • CHigh blood pressure
  • DStunted growth

Q4:

The figure shows the daily energy requirements of different groups of people.

How much more or less energy per day does a female office worker need compared to a male office worker?

  • A2,000 kJ less
  • B200 kJ less
  • C2,000 kJ more
  • D200 kJ more

Calculate the percentage increase in energy requirement when a female office worker becomes pregnant.

Which statement about the data in the graph is true?

  • AFemale construction workers require less energy per day than male office workers.
  • BA pregnant woman requires more energy per day than a male office worker.
  • CAs children grow, they require more energy per day.
  • DMales require more energy per day than females at all ages.

Q5:

Which of the following is not a way of keeping your body healthy?

  • AEating a balanced diet
  • BExercising regularly
  • CTaking recreational drugs
  • DGetting at least 8 hours of sleep

Q6:

Which of the following health problems is more likely for a person suffering from starvation?

  • ADeficiency diseases
  • BDiabetes
  • CHeart disease
  • DStroke

Q7:

True or False: Health is defined as the absence of disease.

  • AFalse
  • BTrue

Q8:

The figure shows that a person’s body mass index (BMI) is based on their height and weight.

There are four categories that show health status: underweight, normal, overweight, and obese.

What is the health status of a person who is 155 cm tall and weighs 80 kg?

  • AObese
  • BNormal
  • COverweight
  • DUnderweight

Q9:

What are the units of energy used when stating the energy content of different foods?

  • AkJ
  • BN
  • Cm/s
  • Dkg

Q10:

You need 5.4 kJ of energy per hour (h) to maintain basic body functions. The basic energy requirement (BER) of a person can be calculated using the following formula: BERkJdayhbodymasskg(/)=5.4×24×().

Calculate the BER of a person of mass 50 kg.

  • A6,480 kJ/day
  • B2.592 kJ/day
  • C1,200 kJ/day
  • D270 kJ/day

Walking for 1 hour uses an additional 800 kJ of energy. Calculate the energy a 50 kg person uses in one day if they walk for 75 minutes every day.

  • A2,200 kJ/day
  • B7,480 kJ/day
  • C5,480 kJ/day
  • D7,280 kJ/day
