Prevention of chronic diseases

Correct answer: A. To soften stool, support its easy passage, and help prevent constipation

Explanation: Many types of fibre hold water and increase stool bulk. Adequate fluid helps keep that stool softer and easier to pass, supporting regular bowel movements. Increasing fibre suddenly without enough fluid may cause bloating or worsen hard stools in some people. Fibre is not simply digested and absorbed like a sugar, so options B and C are inaccurate.

Correct answer: A. Total sodium intake includes contributions from all sources, including packaged foods

Explanation: Total sodium includes salt added during cooking or at the table as well as sodium already present in packaged foods such as savoury snacks, instant noodles, sauces, pickles, and canned products. Counting only visible table salt underestimates intake. Reading labels and limiting highly processed foods therefore supports more accurate sodium reduction and hypertension prevention.

Correct answer: A. Their combined effects can raise the risk of cancer, cardiovascular disease and other chronic diseases

Explanation: Smoking and excess alcohol are each modifiable risk factors for several chronic diseases. When they occur together, exposure to harmful substances and behaviours may compound risks for cancers, cardiovascular disease, liver disease, and other conditions. Prevention should therefore address both through counselling, achievable reduction or cessation goals, social support, and professional treatment where needed.

Correct answer: A. To assess adherence, progress and barriers, and make necessary modifications to the diet plan

Explanation: A follow-up allows the counsellor and client to review adherence, progress, symptoms, weight or other relevant measures, and practical barriers. The plan can then be adjusted to changing needs, preferences, medical findings, and circumstances. Follow-up also reinforces motivation and corrects misunderstandings. Keeping the first plan unchanged without review may make it unsuitable or unrealistic.

Correct answer: A. A balanced diet maintains nutrient adequacy and is easier to follow long term

Explanation: A balanced pattern provides variety and appropriate amounts of energy, protein, fibre, vitamins, and minerals. Unnecessary elimination can create nutrient gaps and make an eating plan difficult to sustain. Balance does not mean equal portions of every food; it means suitable proportions based on age, activity, health status, culture, and professional advice. Medically necessary restrictions should include suitable replacements.

Correct answer: A. It may help control total energy intake, late-night overeating, and dietary glycaemic load

Explanation: A very large late meal may increase total daily energy intake and, when rich in refined carbohydrates, may produce a high glycaemic load. Moderating the portion and choosing fibre-rich, minimally processed foods can support weight and glucose management. This does not mean everyone must skip dinner; timing, composition, total intake, activity, and individual medical advice all matter.

Correct answer: A. To make the change strategy according to the person's stage

Explanation: People differ in whether they are unaware of a risk, considering change, preparing to act, or already maintaining a new behaviour. Assessing readiness helps the counsellor choose an appropriate strategy, such as building awareness, resolving concerns, setting a first goal, or preventing relapse. It supports respectful, individualized counselling rather than imposing identical advice on everyone.

Correct answer: A. They may contain hidden sugar, unhealthy fat or salt

Explanation: A health claim or familiar packaging does not guarantee that biscuits are low in sugar, saturated fat, trans fat, sodium, or calories. Regular or large consumption can displace more nutritious foods and contribute to excess energy intake. Consumers should read the ingredient list and nutrition panel, compare products, control portions, and prefer minimally processed, fibre-rich foods where possible.

Correct answer: A. A person makes better decisions by understanding labels, advice, and risk messages

Explanation: Health literacy enables a person to understand nutrition labels, medical advice, screening information, and risk messages. This knowledge supports healthier food choices, regular physical activity, timely medical consultation, and adherence to preventive recommendations. Therefore, it helps reduce modifiable risk factors for chronic diseases.

Correct answer: A. Disease risk, body weight, lifestyle habits, and screening results may change

Explanation: Prevention must be responsive to a person’s current risk. Weight, diet, activity, blood pressure, blood glucose, lipid levels, age, and family circumstances can change. Regular reassessment allows dietary advice, exercise targets, screening, and follow-up to be modified before a chronic disease develops.

Correct answer: A. To increase healthy food options at home and reduce unhealthy impulsive buying

Explanation: Family participation makes healthy shopping a shared routine rather than an individual effort. A planned list can include vegetables, fruits, whole grains, pulses, and other nutritious foods while limiting highly processed, sugary, salty, or fatty products. This improves the home food environment and supports long-term prevention.

Correct answer: A. Because healthy habits develop from childhood

Explanation: Nutrition education in schools helps children understand balanced eating, hygiene, portion control, physical activity, and the harmful effects of excessive sugar, salt, and unhealthy fats. Habits formed during childhood can continue into adulthood and may lower the risk of obesity, diabetes, hypertension, and other chronic diseases. Thus, school-based nutrition education supports prevention and is related to the preventive scope of clinical nutrition.

Correct answer: A. By giving healthy eating and lifestyle advice

Explanation: Clinical nutrition contributes to prevention by promoting balanced eating, suitable portions, physical activity, healthy weight and reduced intake of excess salt, sugar and unhealthy fats. These measures can lower risk for several chronic conditions, although they do not guarantee prevention in every person. Individual advice should reflect age and health status.

Correct answer: A. By giving healthy canteen options and lifestyle advice

Explanation: Workplace obesity prevention can combine healthier canteen choices, portion guidance, nutrition education, and support for regular physical activity. The aim is not starvation or unrealistic restriction, but sustainable lifestyle improvement that lowers long-term risk of obesity, diabetes, and cardiovascular disease.

Correct answer: A. By advising on food, activity, sleep, and behaviour

Explanation: Lifestyle counselling is an important clinical nutrition approach for preventing and managing chronic conditions. Advice may cover balanced food choices, appropriate portions, physical activity, sleep, stress management, and sustainable behaviour change. Such counselling is individualized and practical; it does not depend on cosmetic changes to food, fear, or the unnecessary removal of entire food groups.

Correct answer: A. Through healthy-eating guidelines and awareness programmes

Explanation: Population-level nutrition actions can promote balanced diets, appropriate portions, physical activity, food safety, and reduced intake of excess salt, sugar, or unhealthy fats. Guidelines and awareness programmes help prevent risk factors for obesity, diabetes, hypertension, and cardiovascular disease. Effective programmes should be evidence-based, culturally suitable, accessible, and supported by healthy environments.

Correct answer: C. Preventive nutrition

Explanation: Nutrition counselling is not limited to people who are already ill. Advising a healthy person about balanced food, appropriate fat and salt intake, fibre, activity and weight management can lower future cardiovascular risk. Since the purpose is to prevent disease before it develops, the work is preventive nutrition rather than disease treatment or advertising.

Correct answer: D. Because diet and lifestyle can affect many disease risks

Explanation: Nutrition influences body weight, blood glucose, blood pressure, blood lipids, bowel health, and overall metabolic function. Balanced eating, physical activity, and practical counselling can reduce risk or delay the onset of several chronic diseases, while therapeutic diets help manage established illness. Therefore, prevention and treatment are both part of the field’s scope.

Correct answer: D. Because food, activity and weight are linked with many disease risks

Explanation: Lifestyle-related conditions such as obesity, type 2 diabetes, hypertension, and cardiovascular disease are influenced by dietary pattern, physical activity, body weight, sleep, and other behaviours. Clinical nutrition helps assess risk, set achievable goals, modify food intake, support medication plans, and monitor outcomes. It complements medical treatment rather than claiming that diet alone replaces medicine; D is correct.

Correct answer: B. Developing healthy eating behaviour and disease prevention from childhood

Explanation: School nutrition programmes can establish healthy food habits early, improve nutrition literacy, identify risks such as undernutrition or unhealthy weight, and support prevention of diet-related disease. They may also encourage safe, nutritious, and acceptable school meals. Their purpose is broader than academic marks and includes long-term health promotion; therefore, option B is the best answer.

Correct answer: C. By improving the workplace food environment, lifestyle, and disease risk

Explanation: Corporate wellness programmes can improve access to healthier foods, support regular meals and hydration, encourage physical activity, and provide evidence-based counselling. These measures may reduce modifiable risks for obesity, diabetes, hypertension, and other chronic conditions, while respecting employee choice and privacy. Punishment, removing healthy choices, or misleading sales is not professional nutrition practice; therefore, C is correct.
