## Exercise 1 – Fill in the missing words

Passage:

> In order to stay healthy, the body needs seven main chemicals which are called food types. These are carbohydrates, proteins, fats, minerals, vitamins, fibre and water. A balanced diet contains the correct amounts of all seven food types. Carbohydrates are sugars and starch. Carbohydrates give us energy quickly. Fats also give us energy but they release it much more slowly. Stored fat under the skin also helps us to keep warm. We need protein to help us grow and to repair damaged parts. Minerals and vitamins are needed in smaller amounts to keep the body healthy. Fibre helps to keep the food moving along the intestines.

✔ Explanation of Answers:

1. healthy – The goal of a balanced diet is to maintain good health.
2. types – The seven categories (carbs, protein, fats, etc.) are referred to as “food types” — this is confirmed by the table below and common nutrition terminology.
3. fats – Listed as one of the seven main food chemicals.
4. correct – A balanced diet means getting the *right* or *correct* proportions of each nutrient.
5. starch – Carbohydrates include both sugars and starches (e.g., potatoes, bread, cereals).
6. energy – Fats are a concentrated source of energy, just like carbs — though released more slowly.
7. warm – Body fat acts as insulation, helping regulate body temperature.
8. protein – Essential for growth and tissue repair (muscle, skin, organs).
9. vitamins – Along with minerals, they’re micronutrients needed in small amounts for health.
10. intestines – Fibre adds bulk to stool and helps food move through the digestive tract — specifically the intestines.

## Exercise 2 – Write down the main FOOD TYPES that each of the foods below contain

*(Images from left to right, top to bottom)*

Top Row:

1. Potatoes → Carbohydrate
*(Starchy vegetable — high in starch, a complex carb)*

2. Fish → Protein
*(Lean animal protein source — also contains some fats, especially omega-3s, but primarily classified as protein)*

3. Onion & Banana → Vitamins / Fibre
*(Both are fresh produce — rich in vitamins (like vitamin C) and dietary fibre. Since “vitamins” is listed as a food type and “fibre” is separate, either could be acceptable. However, since the banana is sweet and starchy, it also has carbs — but the question asks for the *main* food type. Given the context of the worksheet, Vitamins is best here because fruits/veg are grouped under “Vitamins” in the table.)*
➤ Answer: Vitamins *(or Fibre — but Vitamins is more directly supported by the table)*

4. Nuts → Fat / Protein
*(Nuts are high in healthy fats and also contain significant protein. But since “fat” is listed as a primary food type and nuts are often categorized under fats/oils in food groups, Fat is the best single answer here.)*
➤ Answer: Fat

---

Bottom Row:

5. Whole grain bread → Carbohydrate
*(Made from grains — primary source of starch/carbs)*

6. Milk → Protein / Minerals
*(Milk contains protein, calcium (mineral), and some fat. According to the table, milk is listed under “Protein” and “Minerals” (calcium). Since the question asks for the *main* food type, and milk is commonly associated with protein and calcium, either could work. But looking at the table, milk is listed under Protein first.)*
➤ Answer: Protein

7. Chicken → Protein
*(Classic animal-based protein source)*

8. Cupcake → Carbohydrate
*(Made from flour, sugar, butter — high in carbs and fats, but primarily carbs due to sugar and flour. In the table, cakes are listed under Carbohydrate.)*
➤ Answer: Carbohydrate
