Nutrition and Food Sources Questions
-
liver and liver products, such as pâté
-
Unpasteurised cheese
-
Cooked meat
-
Shark, swordfish and marlin
C
Correct answer
Explanation
Cooked meat is safe to consume during pregnancy as long as it is prepared thoroughly to eliminate harmful bacteria. In contrast, liver contains high levels of vitamin A which can be harmful, unpasteurised cheese carries a risk of listeria, and large fish like shark contain high levels of mercury.
B
Correct answer
Explanation
While folate is found in foods like leafy greens, it is highly difficult to consistently obtain the recommended daily amount of 400 micrograms from diet alone. Therefore, taking a daily folic acid supplement is highly recommended for pregnant mothers.
B
Correct answer

-
Muscular strength
-
Energy
-
Protection against disease
B
Correct answer
Explanation
Cereals, potatoes, and bread are rich in carbohydrates, which are the body's primary and most efficient source of energy. When consumed, these foods are broken down into glucose, which fuels cellular functions and physical activities.
B
Correct answer
Explanation
A balanced diet must contain a wide variety of nutrient-dense foods from all major food groups, including fruits, vegetables, whole grains, proteins, and healthy fats. Biscuits and processed snacks are typically high in refined sugars, unhealthy fats, and sodium, and lack essential nutrients, making them unsuitable as the foundation of a balanced diet.
-
Fats, carbohydrates, proteins, vitamin and mineral

All nutrients and water
-
All nutrients, water and roughage
C
Correct answer
Explanation
A balanced diet is defined as one that provides all the essential nutrients (carbohydrates, proteins, fats, vitamins, and minerals) along with adequate amounts of water and dietary fiber (roughage). Roughage is crucial for healthy digestion and preventing constipation, while water is vital for all metabolic processes.
-
Milk
-
Eggs
-
Fruit and vegetables
-
Red meat
C
Correct answer
Explanation
Scientific evidence strongly suggests that a diet rich in fruits and vegetables can lower the risk of developing several types of cancer due to their high content of vitamins, minerals, fiber, and phytochemicals. Red meat is actually associated with an increased risk of certain cancers, while milk and eggs do not have the same broad protective association.

Read meat
-
Peas, beans and lentils

C
Correct answer
