Question 1Food, Nutrition and Health

Which nutrient is the body's most concentrated source of energy, supplying 9 kcal per gram?

  1. Dietary fibre
  2. Vitamin C
  3. Fat Correct answer.
  4. Protein

Explanation

Fat supplies about 9 kcal per gram, roughly twice the energy of carbohydrate or protein at 4 kcal per gram. This makes it the most energy-dense macronutrient, which is why high-fat foods are calorie-rich.

Question 2Food, Nutrition and Health

Which food group is the richest dietary source of calcium for a Maltese teenager?

  1. Olive oil
  2. Oranges
  3. Milk and yoghurt Correct answer.
  4. White bread

Explanation

Milk and yoghurt are dairy foods rich in calcium, which is needed for bone growth during adolescence. A portion of dairy at breakfast and as a snack helps meet the daily calcium requirement.

Question 3Food, Nutrition and Health

Which vitamin is produced in the skin when it is exposed to sunlight?

  1. Vitamin B12
  2. Vitamin D Correct answer.
  3. Vitamin K
  4. Vitamin A

Explanation

Ultraviolet light converts a cholesterol compound in the skin into vitamin D, which then helps absorb calcium. Short regular sun exposure, common in Malta, supports this synthesis.

Question 4Food, Nutrition and Health

Which mineral is needed for the transport of oxygen in the blood?

  1. Iron Correct answer.
  2. Sodium
  3. Potassium
  4. Iodine

Explanation

Iron is a component of haemoglobin, the red blood cell pigment that carries oxygen around the body. Low iron intake can lead to iron-deficiency anaemia.

Question 5Food, Nutrition and Health

According to healthy eating guidance, what proportion of daily energy should come from carbohydrate?

  1. About 10 per cent
  2. About 80 per cent
  3. About 25 per cent
  4. About 50 per cent Correct answer.

Explanation

Guidelines recommend that carbohydrate provides around half of daily energy, with most of it from starchy and fibre-rich sources. Fat then supplies about a third and protein the remainder.

Question 6Food, Nutrition and Health

Which term describes a diet that supplies all nutrients in the correct amounts for good health?

  1. A therapeutic diet
  2. A balanced diet Correct answer.
  3. A vegan diet
  4. A fad diet

Explanation

A balanced diet provides energy and all essential nutrients in the right proportions to maintain health. The other diets describe particular patterns or medical regimes rather than the general definition.

Question 7Food, Nutrition and Health

Which condition is caused by a deficiency of vitamin C?

  1. Scurvy Correct answer.
  2. Night blindness
  3. Rickets
  4. Beriberi

Explanation

Scurvy results from insufficient vitamin C, causing bleeding gums, poor wound healing and fatigue. Fresh fruit and vegetables such as citrus and peppers prevent it.

Question 8Food, Nutrition and Health

Which cooking method best preserves water-soluble vitamins in vegetables?

  1. Soaking in water overnight before cooking
  2. Steaming until just tender Correct answer.
  3. Frying at a very high temperature
  4. Boiling in plenty of water for a long time

Explanation

Water-soluble vitamins such as vitamin C and B vitamins leach into cooking water and are destroyed by heat. Steaming for a short time uses little or no water and limits vitamin loss.

Question 9Food, Nutrition and Health

A person with coeliac disease must avoid which cereal protein?

  1. Casein found in cheese
  2. Albumin found in egg white
  3. Lactose found in milk
  4. Gluten found in wheat, barley and rye Correct answer.

Explanation

Coeliac disease is an autoimmune reaction to gluten, so wheat, barley and rye must be avoided. Safe alternatives include rice, maize and certified gluten-free products.

Question 10Food, Nutrition and Health

Why is dietary fibre important in the diet?

  1. It supplies most of the body's vitamin D.
  2. It provides a concentrated source of energy.
  3. It helps prevent constipation by adding bulk to the diet. Correct answer.
  4. It is the main building material for muscle.

Explanation

Fibre adds bulk to the diet and holds water in the intestine, helping to prevent constipation. It also supports bowel health and can help control blood cholesterol and glucose levels.

Question 11Food, Nutrition and Health

Which food is the safest choice to reduce the risk of food poisoning from raw animal products?

  1. Undercooked chicken
  2. Unwashed salad leaves
  3. Raw minced beef eaten immediately after purchase
  4. Pasteurised milk kept refrigerated Correct answer.

Explanation

Pasteurisation kills harmful bacteria such as Salmonella and Listeria in milk, and refrigeration slows their growth. This makes pasteurised refrigerated milk a low-risk choice.

Question 12Food, Nutrition and Health

Which practice best prevents cross-contamination in the kitchen?

  1. Storing raw meat above ready-to-eat food in the fridge
  2. Thawing raw meat on the kitchen counter overnight
  3. Using the same board for raw chicken and salad without washing
  4. Using separate colour-coded chopping boards for raw meat and ready-to-eat food Correct answer.

Explanation

Separate colour-coded boards stop bacteria from raw meat transferring to ready-to-eat foods. This is a key control in preventing foodborne illness at home and in catering.

Question 13Food, Nutrition and Health

Which change would most reduce the saturated fat content of a family meal?

  1. Choosing full-fat cheese over reduced-fat cheese
  2. Replacing butter with olive oil when cooking vegetables Correct answer.
  3. Adding extra cream to a soup
  4. Serving fried chips instead of boiled potatoes

Explanation

Olive oil is rich in unsaturated fat, while butter is high in saturated fat, so swapping them lowers saturated fat. Small ingredient substitutions are practical ways to improve a diet.

Question 14Food, Nutrition and Health

Which nutrient is most at risk of deficiency in a strictly vegan diet unless fortified foods are used?

  1. Fibre
  2. Vitamin B12 Correct answer.
  3. Vitamin C
  4. Potassium

Explanation

Vitamin B12 occurs naturally almost only in animal foods, so vegans need fortified foods or supplements. Vitamin C, potassium and fibre are plentiful in plant foods.

Question 15Food, Nutrition and Health

A pregnant woman is advised to avoid certain raw and undercooked foods mainly to reduce the risk of which infection?

  1. Listeriosis Correct answer.
  2. Scurvy
  3. Osteoporosis
  4. Anaemia

Explanation

Listeriosis, caused by Listeria monocytogenes, can be serious in pregnancy and may harm the fetus. Avoiding high-risk foods such as unpasteurised soft cheese and undercooked meat reduces exposure.

Question 16Food, Nutrition and Health

Which statement best describes the role of protein in the diet?

  1. It supplies amino acids for growth and repair of body tissues. Correct answer.
  2. It is the main source of dietary fibre.
  3. It is the body's main store of energy.
  4. It is needed only by athletes and children.

Explanation

Protein supplies amino acids used to build and repair tissues such as muscle, skin and blood. Everyone needs protein daily, with higher needs during growth, pregnancy and recovery.

Question 17Food, Nutrition and Health

Which factor would most increase a person's daily energy requirement?

  1. Sleeping for an extra hour each night
  2. Increasing the amount of vigorous physical activity Correct answer.
  3. Eating more fruit and vegetables
  4. Drinking more water

Explanation

Energy requirement depends on basal metabolic rate plus physical activity and the thermic effect of food. Vigorous activity raises energy expenditure, so the requirement increases.

Question 18Food, Nutrition and Health

What is the main purpose of fortifying a food such as flour with folic acid?

  1. To increase its shelf life
  2. To reduce the risk of neural tube defects in babies Correct answer.
  3. To improve the flavour of the product
  4. To make the product cheaper to produce

Explanation

Folic acid is needed early in pregnancy for the normal development of the neural tube. Fortifying staple foods helps women reach adequate intake before conception.

Question 19Food, Nutrition and Health

Which statement correctly describes the glycaemic index of a food?

  1. It measures how much water a food contains.
  2. It measures how quickly a food raises blood glucose compared with a reference food. Correct answer.
  3. It measures the vitamin content of a food.
  4. It measures the total fat content of a food.

Explanation

The glycaemic index ranks carbohydrate foods by how fast and how much they raise blood glucose compared with a reference such as glucose. Low-GI foods raise blood glucose slowly and steadily.

Question 20Food, Nutrition and Health

A patient with high blood pressure is advised to reduce salt intake. Which change would help most?

  1. Choosing fresh herbs and spices instead of stock cubes and processed sauces Correct answer.
  2. Increasing the amount of cured meat eaten
  3. Adding soy sauce to every meal
  4. Adding extra salt at the table to taste the food

Explanation

Processed sauces, stock cubes and cured meats are major sources of sodium, so replacing them with herbs and spices lowers salt intake. This helps reduce blood pressure.

Question 21Food, Nutrition and Health

A teenager who eats only white bread, chips and sugary drinks is most at risk of which combination of problems?

  1. Excess fibre and iron deficiency
  2. Excess vitamin A and anaemia
  3. Poor dental health and low intake of vitamins and fibre Correct answer.
  4. High calcium intake and obesity

Explanation

A diet dominated by refined starch and sugar is low in fibre, vitamins and minerals and encourages tooth decay. Such diets are associated with poor dental health and inadequate micronutrient intake.

Question 22Food, Nutrition and Health

Why does the body store excess energy as fat rather than as protein?

  1. Fat is the only nutrient that contains nitrogen.
  2. Fat can be stored with little water and yields more energy per gram. Correct answer.
  3. Protein is stored in the liver without limit.
  4. Protein cannot be digested by the body.

Explanation

Fat is stored in adipose tissue with little associated water and yields about 9 kcal per gram, making it an efficient energy reserve. Protein is not a dedicated storage nutrient and is used mainly for tissue building.

Question 23Food, Nutrition and Health

A family wants to reduce food waste while maintaining a balanced diet. Which strategy best achieves both aims?

  1. Buying large quantities of fresh produce and freezing none of it
  2. Removing fruit and vegetables to reduce spoilage
  3. Buying only foods that are on special offer regardless of need
  4. Planning meals, using leftovers safely and storing food correctly Correct answer.

Explanation

Meal planning reduces overbuying, correct storage extends shelf life and safe use of leftovers prevents waste. These measures keep fruit, vegetables and other nutritious foods in the diet rather than removing them.

Question 24Food, Nutrition and Health

Which explanation best accounts for the higher iron requirement of adolescent girls compared with younger children?

  1. Growth spurts and the onset of menstruation increase iron losses and needs. Correct answer.
  2. Adolescents eat less food than younger children in total.
  3. Girls digest iron less efficiently than boys of the same age.
  4. Iron is only needed once growth has stopped.

Explanation

Adolescent growth increases blood volume and muscle mass, raising iron needs, while menstruation adds regular losses. Together these factors mean adolescent girls have a particularly high iron requirement.

Question 25Food, Nutrition and Health

A caterer must provide a suitable main meal for a guest with lactose intolerance. Which choice is most appropriate?

  1. Grilled chicken with rice and vegetables Correct answer.
  2. A large bowl of milk-based soup
  3. Creamy cheese pasta with milk-based sauce
  4. Yoghurt with fresh fruit

Explanation

Lactose intolerance means milk sugar must be limited, so a meal of grilled chicken, rice and vegetables avoids dairy. Many lactose-intolerant people can still tolerate small amounts, but this meal is the safest choice.

Question 26Food, Nutrition and Health

Which nutrient functions mainly as a carrier of fat-soluble vitamins A, D, E and K through the digestive tract and into the lymph?

  1. Vitamin C
  2. Dietary fibre
  3. Dietary fat Correct answer.
  4. Calcium

Explanation

Fat-soluble vitamins dissolve only in lipid, so they are absorbed together with digested fat and transported in chylomicrons via the lymph. A very low-fat diet can therefore impair absorption of these vitamins even when intake is adequate.

Question 27Food, Nutrition and Health

Which mineral is essential for the formation of haemoglobin, and is best absorbed from red meat and from plant foods eaten with a source of vitamin C?

  1. Fluoride
  2. Iron Correct answer.
  3. Iodine
  4. Sodium

Explanation

Iron is a component of haem in haemoglobin, which carries oxygen in red blood cells. Haem iron from meat is well absorbed, while non-haem iron from plants needs vitamin C to be reduced to a more absorbable form.

Question 28Food, Nutrition and Health

A family wants a quick guide to whether their diet supplies enough of each nutrient. Which tool is designed specifically to show the proportions of different food groups needed for a balanced intake?

  1. The glycaemic index table
  2. The Eatwell Guide Correct answer.
  3. A allergen declaration
  4. A food additives list

Explanation

The Eatwell Guide is a visual model that divides foods into groups and shows the proportion each should contribute to the daily diet. It is used to plan balanced meals rather than to analyse single nutrients.

Question 29Food, Nutrition and Health

Which statement correctly describes the difference between a food intolerance and a food allergy?

  1. Both are caused by the same antibody and are treated identically.
  2. Allergy involves an immune response, whereas intolerance does not. Correct answer.
  3. Intolerance involves the immune system, whereas allergy does not.
  4. Both involve IgE antibodies but differ only in severity.

Explanation

A food allergy is an immune-mediated reaction, often involving IgE antibodies, that can cause severe symptoms such as anaphylaxis. Intolerance does not involve the immune system and usually produces digestive symptoms related to the body's inability to process a substance.

Question 30Food, Nutrition and Health

A person needs extra protein to repair tissue after surgery. Which combination of foods would provide complementary amino acids in one meal?

  1. Apple and orange
  2. Butter and white bread
  3. Rice and lentils Correct answer.
  4. Lettuce and cucumber

Explanation

Cereals such as rice are low in lysine, while pulses such as lentils are low in methionine; eaten together they supply a complete amino acid profile. Combining plant proteins in this way supports tissue repair without relying only on animal foods.

Question 31Food, Nutrition and Health

A mother wants to reduce the risk of dental caries in her young child. Which practice is most effective?

  1. Giving sweet drinks only at mealtimes and encouraging water between meals Correct answer.
  2. Letting the child sip juice slowly throughout the day
  3. Offering sugary snacks frequently so meals are smaller
  4. Replacing fruit with dried fruit eaten between meals

Explanation

Caries risk depends on how often teeth are exposed to sugar, not only on total amount. Limiting sweet drinks to mealtimes and drinking water between meals reduces the number of acid attacks on enamel.

Question 32Food, Nutrition and Health

Which change would most increase the amount of calcium absorbed from a vegetable-based meal?

  1. Serving the meal with a source of vitamin D and avoiding excess oxalate-rich foods Correct answer.
  2. Adding more spinach to the meal
  3. Drinking strong tea with the meal
  4. Increasing the salt content of the meal

Explanation

Calcium absorption depends on vitamin D and is reduced by oxalates and phytates, which bind calcium. Choosing low-oxalate vegetables and including vitamin D supports better uptake.

Question 33Food, Nutrition and Health

A teenager skips breakfast and feels tired and unable to concentrate by mid-morning. Which explanation best accounts for this?

  1. Water is retained in the tissues during sleep
  2. Vitamin C is destroyed overnight in the body
  3. Protein stores are used up during sleep
  4. Blood glucose falls after an overnight fast, reducing fuel for the brain Correct answer.

Explanation

After an overnight fast, blood glucose can fall and the brain relies on a steady supply of glucose. A balanced breakfast restores blood glucose and improves concentration and energy.

Question 34Food, Nutrition and Health

A person is advised to increase dietary fibre gradually and to drink more fluids. Why is the fluid advice important?

  1. Fluid neutralises fibre in the stomach
  2. Fluid prevents fibre from being fermented
  3. Fluid increases the energy value of fibre
  4. Fibre absorbs water, and without enough fluid it can cause constipation and bloating Correct answer.

Explanation

Fibre such as cellulose holds water and softens stool; without adequate fluid, a high-fibre diet can become hard and cause discomfort. Increasing fluid alongside fibre helps maintain regular bowel function.

Question 35Food, Nutrition and Health

Which cooking method best preserves the thiamin content of rice?

  1. Prolonged soaking before cooking
  2. Frying at a very high temperature
  3. Boiling in a large volume of water and discarding the water
  4. Steaming with minimal water Correct answer.

Explanation

Thiamin is water-soluble and heat-sensitive, so it leaches into cooking water that is discarded. Steaming with little water and short cooking times limits leaching and destruction.

Question 36Food, Nutrition and Health

A person following a low-income budget wants to meet protein needs. Which choice gives the most protein per unit of cost?

  1. Imported fresh salmon
  2. Prepared ready meals
  3. Soft cheese
  4. Pulses such as lentils and beans Correct answer.

Explanation

Pulses are inexpensive, store well and provide a good amount of plant protein per unit cost. They can be combined with cereals to give a complete amino acid profile.

Question 37Food, Nutrition and Health

A family wants to lower the glycaemic load of their evening meal without reducing total carbohydrate too much. Which change is most effective?

  1. Drinking fruit juice with the meal
  2. Replacing white rice with wholegrain rice and adding vegetables Correct answer.
  3. Eating the meal more quickly
  4. Adding sugar to the sauce

Explanation

Glycaemic load depends on both the quality and quantity of carbohydrate. Wholegrain rice has a lower glycaemic index and vegetables add fibre, slowing glucose absorption.

Question 38Food, Nutrition and Health

A patient with newly diagnosed type 2 diabetes asks how diet can help. Which advice is most appropriate?

  1. Replace meals with sugary drinks for energy
  2. Eat regular meals based on high-fibre carbohydrates and limit free sugars Correct answer.
  3. Eat one large meal late at night
  4. Avoid all carbohydrates completely

Explanation

Regular meals based on high-fibre, slowly absorbed carbohydrates help control blood glucose, while limiting free sugars reduces sharp rises. Carbohydrate should not be eliminated entirely, as it is the body's main fuel.

Question 39Food, Nutrition and Health

A family's food budget is tight, yet they want a nutritious diet. Which strategy best balances cost and nutritional quality?

  1. Buy fresh produce in bulk without a storage plan
  2. Buy seasonal vegetables and plan meals around pulses and wholegrains Correct answer.
  3. Buy only premium branded products
  4. Rely mainly on takeaway meals

Explanation

Seasonal produce and plant proteins such as pulses and wholegrains are economical and nutritious. Planning meals reduces waste and helps ensure a balanced intake despite a limited budget.

Question 40Food, Nutrition and Health

A community wants to reduce iron-deficiency anaemia among young women. Which intervention is most likely to be effective in the long term?

  1. Distributing iron supplements once only
  2. Nutrition education promoting iron-rich foods with vitamin C, plus food fortification Correct answer.
  3. Advising women to drink tea with every meal
  4. Encouraging a diet based mainly on refined cereals

Explanation

Long-term reduction of anaemia requires both increased intake and improved absorption of iron. Education on combining iron-rich foods with vitamin C, together with fortification, addresses both dietary quality and population reach.

Question 41Food Science, Food Safety and Meal Provision

Which temperature range is the danger zone in which food-poisoning bacteria multiply most rapidly?

  1. Between -18 °C and 0 °C
  2. Between 70 °C and 100 °C
  3. Between 0 °C and 5 °C
  4. Between 5 °C and 63 °C Correct answer.

Explanation

Food safety guidance identifies roughly 5 °C to 63 °C as the range in which bacteria such as Salmonella and Staphylococcus aureus multiply fastest, so high-risk foods should be kept out of it. Chilled storage below 5 °C slows growth, and thorough reheating above 70 °C kills most vegetative cells.

Question 42Food Science, Food Safety and Meal Provision

A student is preparing a packed lunch for a school trip on a warm day. Which practice best reduces the risk of food-borne illness?

  1. Chilling the sandwich thoroughly and carrying it in an insulated cool bag Correct answer.
  2. Warming the sandwich before wrapping it in foil
  3. Keeping the sandwich at room temperature in a paper bag
  4. Adding mayonnaise to the filling and leaving it in sunlight

Explanation

On a warm day a chilled, insulated cool bag keeps the food below the danger zone and slows bacterial multiplication. Pre-chilling the food before packing removes heat that would otherwise help bacteria grow during transport.

Question 43Food Science, Food Safety and Meal Provision

Which of the following is a high-risk food that should be stored under refrigeration?

  1. Cooked chicken Correct answer.
  2. White rice
  3. Dried pasta
  4. Plain flour

Explanation

High-risk foods are moist, protein-rich foods that support rapid bacterial growth, and cooked poultry is a classic example that must be refrigerated. Dry staples such as pasta, rice and flour have low moisture and keep safely in a cool, dry cupboard.

Question 44Food Science, Food Safety and Meal Provision

Which cooking method is most suitable for making a clear, flavoursome stock from bones and vegetables?

  1. Boiling vigorously for ten minutes
  2. Simmering gently for several hours Correct answer.
  3. Grilling over a high heat
  4. Deep-frying rapidly

Explanation

Gentle simmering extracts flavour and gelatin from bones and vegetables while keeping the liquid clear. Vigorous boiling agitates the mixture, emulsifies fat and clouds the stock, so it is avoided in stock-making.

Question 45Food Science, Food Safety and Meal Provision

Which of these is the main purpose of blanching vegetables before freezing?

  1. To soften the vegetables completely
  2. To add salt to the vegetable tissue
  3. To change the colour to brown
  4. To inactivate enzymes that cause spoilage Correct answer.

Explanation

Brief heating in boiling water inactivates enzymes such as peroxidase and polyphenol oxidase that would otherwise cause off-flavours, colour loss and texture breakdown during frozen storage. The vegetables are then cooled quickly before freezing.

Question 46Food Science, Food Safety and Meal Provision

Which nutrient is most likely to be lost if vegetables are boiled in a large volume of water and the water is discarded?

  1. Protein
  2. Dietary fibre
  3. Vitamin C Correct answer.
  4. Vitamin A

Explanation

Vitamin C is water-soluble and heat-sensitive, so it leaches into cooking water and is destroyed by prolonged heat. Discarding the water therefore removes a large share of this vitamin.

Question 47Food Science, Food Safety and Meal Provision

What does the term 'cross-contamination' mean in a domestic kitchen?

  1. Storing food in containers of the wrong size
  2. Adding too many ingredients to a recipe
  3. Transfer of harmful bacteria from one food or surface to another Correct answer.
  4. Cooking food at too low a temperature

Explanation

Cross-contamination occurs when bacteria from raw foods such as poultry or their juices are transferred to ready-to-eat foods via hands, chopping boards, knives or cloths. Separating raw and cooked foods and cleaning surfaces prevents it.

Question 48Food Science, Food Safety and Meal Provision

Which piece of equipment is used to measure the core temperature of a cooked joint of meat?

  1. A measuring jug
  2. A weighing scale
  3. A colander
  4. A probe thermometer Correct answer.

Explanation

A probe thermometer is inserted into the thickest part of the food to confirm that the core has reached a safe temperature, typically above 75 °C for poultry. This verifies that cooking has been adequate.

Question 49Food Science, Food Safety and Meal Provision

Why is salt used in the preservation of meat such as ham?

  1. It reduces the water available to microorganisms Correct answer.
  2. It raises the pH of the meat
  3. It sweetens the meat during curing
  4. It provides a source of vitamin C

Explanation

Salt lowers water activity by drawing water out of microbial cells, which inhibits the growth of spoilage and pathogenic bacteria. This is the principle behind curing, often combined with nitrites and drying.

Question 50Food Science, Food Safety and Meal Provision

A sauce has separated during cooking and looks grainy. Which explanation best accounts for this?

  1. The sauce was stirred with a wooden spoon
  2. The sauce contained too little liquid
  3. The sauce was heated too quickly or unevenly, causing the emulsion to break Correct answer.
  4. The sauce was served too hot

Explanation

Emulsions such as hollandaise or a roux-based sauce break when heat is applied too rapidly or unevenly, causing fat droplets to coalesce and separate. Gentle, even heating and constant whisking help maintain a stable emulsion.
