Lesson summary

This week, we will be focusing on developing healthy eating habits. Understanding what we eat and how it affects our bodies is extremely important. Many South Africans, including children, face challenges like malnutrition (not getting enough nutrients) or obesity (being overweight). Making good food choices helps us grow strong, stay healthy, concentrate better in school, and have more energy to play and enjoy our lives. Learning about healthy eating habits is not just about knowing what foods are good for us, it's about making informed choices that benefit our well-being and contribute to a healthier community.

Lesson notes

What are Food Groups? Food groups are categories of foods that share similar nutritional properties. Eating a variety of foods from each group ensures our bodies get all the vitamins, minerals, and other nutrients we need to function properly.

The Five Food Groups: Grains (Carbohydrates): Provide energy for our bodies. Examples include bread (brown is better!), rice, maize porridge (pap), mealie bread, pasta, and oats. These are particularly important as a staple food in many South African homes. Why? Grains release energy slowly, keeping you full for longer and helping you concentrate in class. Brown rice and whole-wheat bread have more fibre, which aids digestion.

South African example: Pap (maize porridge) is a cheap and nutritious grain that can be eaten for breakfast, lunch, or dinner.

Fruits: Source of vitamins, minerals, and fibre. Examples include oranges, apples, bananas, mangoes (when in season!), grapes, and pawpaw. Why? Fruits boost our immune system and help us fight off illnesses. They also keep our skin healthy.

South African example: Mangoes are abundant and delicious in many parts of South Africa during summer.

Vegetables: Also full of vitamins, minerals, and fibre. Examples include spinach, carrots, tomatoes, potatoes, cabbage, butternut, and beetroot. Remember leafy greens like morogo! Why? Vegetables are essential for growth and overall health. They also help protect us from diseases.

South African example: Morogo (African spinach) is a nutritious and affordable leafy green that is widely consumed.

Protein: Essential for building and repairing muscles, and for overall growth. Examples include meat (chicken, beef, fish), eggs, beans, lentils (dhal), nuts, and dairy products like milk and yogurt. Why? Protein helps us grow strong and feel full. It's especially important for growing children.

South African example: Beans and lentils are affordable and readily available sources of protein, especially important for families who can't afford meat every day.

Dairy (or Dairy Alternatives): Provides calcium for strong bones and teeth. Examples include milk, yogurt, cheese, and calcium-fortified soy milk. Why? Calcium is crucial for developing strong bones and preventing diseases like osteoporosis later in life.

South African example: Maas (sour milk) is a traditional South African dairy product that is a good source of calcium.

Understanding Balanced Meals: A balanced meal includes foods from several different food groups. It’s like a puzzle – each piece (food group) contributes something important to the overall picture (your health). A plate filled only with chips, for example, provides energy but lacks the vitamins, minerals, and protein needed for growth and repair.

Worked example

Example 1: A healthy breakfast could be: Maize porridge (grain) with a sliced banana (fruit) and a glass of milk (dairy). This provides energy, vitamins, minerals, and calcium to start the day.

Example 2: A balanced lunch could be: A whole-wheat sandwich (grain) filled with chicken (protein) and lettuce and tomato (vegetables) with an apple (fruit) on the side.

Example 3: A nutritious supper could be: Rice (grain), lentil curry (protein and vegetables), and a side salad (vegetables).

The Importance of Reducing Sugary Drinks and Processed Foods:

Sugary drinks (like fizzy drinks and juice boxes) and processed foods (like chips, sweets, and fast food) are often high in sugar, salt, and unhealthy fats. They provide empty calories, meaning they offer little nutritional value. They can contribute to weight gain, tooth decay, and other health problems. It’s best to limit these foods and drinks and choose healthier options like water, fresh fruit, and homemade snacks.

Guided Practice (With Solutions)

Question 1: Name three foods that belong to the grain food group and explain why they are important for our bodies.

Solution: Three foods from the grain group are bread, rice, and maize porridge. They are important because they provide energy that our bodies need to function.

Question 2: Why is it important to include fruits and vegetables in our daily diet? Give two examples of each.

Solution: Fruits and vegetables are important because they provide vitamins, minerals, and fibre. Examples of fruits are oranges and apples. Examples of vegetables are spinach and carrots.

Question 3: Sipho only eats pap for breakfast, lunch, and supper. Explain why this is not a healthy eating habit and what he could add to his meals to make them more balanced.

Solution: Eating only pap is not healthy because it only comes from one food group (grains). Sipho should add protein (like beans or eggs), fruits (like an apple or banana), vegetables (like spinach or tomatoes), and dairy (like milk or yogurt) to his meals to make them more balanced.

Question 4: Which of these snacks is the healthiest option: a packet of chips, an apple, or a chocolate bar? Explain your answer.

Solution: The healthiest option is an apple. It is a fruit, which provides vitamins, minerals, and fibre. A packet of chips and a chocolate bar are often high in sugar, salt, and unhealthy fats, and provide little nutritional value.
