Practice questions
01 If the diet is low in protein and the person feels hungry soon, which correction is useful?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Add pulses, curd, eggs, or other suitable protein sources
Explanation: Including an appropriate protein source in meals can improve satiety and support muscles, enzymes, hormones, and body repair. Pulses, beans, milk or curd, eggs, fish, poultry, soy, and nuts can be selected according to personal needs and dietary preferences. Protein should be part of a balanced plate with vegetables, whole grains, and adequate water; simply adding sugar does not solve early hunger.
02 If a person removes all fats for weight loss, what problem can occur?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Essential fats and nutrient balance may be affected
Explanation: Dietary fat is energy-dense, so its amount and quality should be managed, but eliminating every source is not appropriate. Essential fatty acids support cell membranes, brain function, and other processes, while some vitamins require fat for absorption. A healthy plan limits trans and excessive saturated fat, uses moderate healthier fats, and maintains overall nutritional balance rather than following an extreme restriction.
03 If a person has high blood pressure and does not exercise, which suggestion is suitable?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Start regular activity according to medical advice
Explanation: Regular, appropriately prescribed physical activity can support blood-pressure control, heart fitness, weight management, mood, and overall metabolic health. A person with hypertension should discuss the suitable intensity and type of exercise with a healthcare professional, especially if symptoms or other conditions exist. Activity should accompany medication advice, lower-sodium eating, monitoring, and follow-up rather than replace them.
04 If a person leaves pulses and vegetables to avoid excess salt, what is the correct correction?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Prepare nutritious pulses and vegetables with less salt
Explanation: Salt reduction should modify preparation, not remove naturally nutritious foods. Pulses provide protein and fibre, while vegetables provide vitamins, minerals, fibre, and protective plant compounds. They can be cooked with less salt and flavoured with herbs, spices, lemon, garlic, or other suitable ingredients. Packaged snacks are often high in sodium, so replacing pulses and vegetables with them would worsen the problem.
05 If a person drinks an unlimited amount of a drink labelled sugar-free every day, what is the caution?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Energy, ingredients, and portion should still be checked
Explanation: “Sugar-free” describes one claim and does not prove that a beverage is calorie-free, nutrient-rich, or suitable in unlimited quantities. The product may contain other sweeteners, energy, sodium, caffeine, or acids, and large amounts may displace water or nutritious foods. Consumers should read the nutrition panel, ingredients, serving size, and total daily intake before making it a regular habit.
06 If a person starts regular walking but does not reduce sweet drinks, why will prevention be limited?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Because both physical activity and sweet-drink intake affect chronic-disease risk
Explanation: Walking can improve fitness, energy expenditure, mood, and glucose regulation, but sweetened beverages may continue adding rapidly absorbed sugar and excess calories. Persistently high intake can undermine weight and metabolic goals and maintain risk for obesity, type 2 diabetes, and cardiovascular disease. Effective prevention combines regular movement with sensible beverage choices; exercise is valuable but cannot erase every dietary risk.
07 If a person dislikes fruits and vegetables, what practical step fits prevention?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Gradually try varied options and preparations according to preference
Explanation: A gradual, preference-sensitive approach can improve acceptance and make healthy eating sustainable. The person can try different seasonal fruits, cooked or raw vegetables, soups, mixed dishes, salads, pulses with vegetables, and varied seasonings or textures. Repeated exposure without force may help. Completely removing these foods can reduce fibre and micronutrient intake, while sweets and tobacco increase health risks rather than solving the problem.
08 If a person eats outside, which choice is better for heart-disease prevention?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. A low-oil, low-salt option
Explanation: When eating outside, choosing food prepared with less oil and salt can reduce exposure to excess energy, saturated fat, and sodium. A person should also prefer vegetables, pulses, whole grains, grilled or steamed preparations, and moderate portions when available. Deep-fried, creamy, and trans-fat foods may increase cardiovascular risk, especially when eaten frequently. One choice does not guarantee prevention, but it is the healthier option among those listed.
09 If a person sleeps less at night and skips morning exercise, which lifestyle component should be improved?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Sleep routine and activity plan
Explanation: The situation directly identifies two connected lifestyle problems: insufficient sleep and inadequate physical activity. A realistic plan should establish a regular sleep schedule, protect adequate sleep time, and gradually include safe daily movement or exercise. Improving these habits can support mood, appetite regulation, weight control, metabolic health, and cardiovascular health. Changing only snacks or beverages would not address the main problem described.
10 If a person records only main meals but not snacks, what will be missing?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Accurate assessment of total energy and hidden salt, sugar, and fat
Explanation: Snacks and drinks between meals can contribute substantial energy, sugar, sodium, saturated fat, or trans fat. Omitting biscuits, fried snacks, sweets, and sweetened beverages makes the estimate of total daily intake incomplete and may hide behaviours relevant to chronic-disease risk. A useful food record should include every food and drink, its approximate quantity, and timing, not only the main meals.
11 If a person understands diet advice but cannot follow it, what is the most useful next step?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: B. Identify practical barriers and make a small plan
Explanation: Option B is correct because understanding advice does not automatically produce adherence. The counsellor should respectfully identify barriers such as cost, time, family food habits, access, taste, or lack of confidence, and then set one or two realistic, measurable goals. Small achievable changes, follow-up, encouragement, and problem-solving make dietary advice practical, sustainable, and safer than blame or extreme restrictions.
12 Control of risk factors in chronic disease prevention is best reflected by what?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: C. Regular healthy habits and improving checkup reports
Explanation: Option C is correct because effective risk-factor control is demonstrated through continuing behaviour and measurable health improvement. Regular physical activity, a balanced eating pattern, suitable weight management, avoidance of tobacco, and appropriate medical follow-up can improve indicators such as blood pressure, blood glucose, and blood lipids. One expensive purchase or one isolated checkup cannot show sustained prevention.
13 Which is the broadest principle of prevention of chronic diseases?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: D. Balanced diet, active life, regular checkups and sustainable behaviour change
Explanation: Option D is correct because chronic-disease prevention is comprehensive and continuous rather than dependent on one food, one medicine, or one test. A balanced diet supplies varied nutrients, activity improves fitness and metabolic health, screening detects risk early, and sustainable behaviour change helps maintain benefits. A holistic plan also adapts to individual health needs and living conditions.
14 Why is a combination of vegetables, pulses, grains and curd good in a balanced plate?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It provides a balanced mix of fibre, protein, energy, calcium and micronutrients
Explanation: Option A is correct because the foods contribute complementary nutrients. Vegetables provide fibre, vitamins, minerals, and protective plant compounds; pulses provide protein and fibre; grains mainly supply energy-giving carbohydrates and, when whole, additional fibre; and curd contributes protein, calcium, and beneficial cultures. Together they improve dietary variety, satiety, and nutrient adequacy within a balanced plate.
15 Why is advice of active breaks important for people doing sitting work?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It can reduce prolonged sitting and increase energy expenditure
Explanation: Active breaks such as standing, walking briefly, stretching, or climbing stairs interrupt prolonged sitting. They add light physical activity, increase energy expenditure, improve circulation, and may reduce some risks linked with sedentary behaviour. They complement, but do not replace, regular exercise, a balanced diet, and other preventive measures.
16 Why is body mass index alone not a complete indicator in disease prevention?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Waist measurement and body-fat distribution also indicate disease risk
Explanation: BMI compares weight with height and is useful for initial screening, but it does not distinguish muscle from fat or show where fat is stored. Abdominal or central fat is associated with higher metabolic and cardiovascular risk. Therefore, waist circumference, clinical history, and other measures should be considered with BMI rather than relying on BMI alone.
17 Why is it important to link regular blood pressure and blood sugar checks with a lifestyle plan?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. So that diet, exercise and other lifestyle measures can be adjusted promptly according to the results
Explanation: Regular monitoring shows whether dietary changes, physical activity, weight management, medicines, or other parts of a prevention plan are producing the desired response. Results allow timely professional advice and adjustment. Testing alone does not remove disease risk, and it never makes a balanced diet or appropriate activity unnecessary.
18 Why is a small amount of unsalted nuts better in heart disease risk reduction?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. They can give good fats but portion matters because they are energy dense
Explanation: Nuts provide unsaturated fats, protein, fibre, and several micronutrients that can fit into a heart-healthy dietary pattern. However, they are energy-dense, so very large portions may add excess calories and hinder weight control. Choosing unsalted nuts also avoids unnecessary sodium. Thus, a modest portion is more appropriate than unlimited consumption.
19 What is the expert rationale for including seasonal vegetables in a prevention plan?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. They can be accessible, fresh, fibrous and micronutrient-rich sources
Explanation: Seasonal vegetables are often fresher, locally available, and less expensive than out-of-season alternatives. They supply dietary fibre, vitamins, minerals, and protective plant compounds while generally adding few calories. Including a variety of vegetables can support weight control, digestive health, and lower chronic disease risk. Availability and preparation still influence the final nutritional value.
20 Why is it necessary to ask about food availability and affordability in nutrition counselling?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. To provide practical, affordable, and sustainable advice for the individual
Explanation: Nutrition advice is effective only when a person can obtain, afford, prepare, and regularly eat the recommended foods. Asking about availability and income helps the counsellor identify local, seasonal, culturally acceptable, and lower-cost alternatives. This improves adherence and sustainability, but it does not replace assessment of health status, nutritional risk, or medical needs.
21 Why is meal combination important in diabetes prevention?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Protein, fibre and fat can modify the effect of carbohydrates
Explanation: The glycaemic response to a meal depends not only on the carbohydrate itself but also on portion size, processing, fibre, protein, fat, and the overall meal pattern. Fibre, protein, and healthy fats may slow digestion and glucose release. This does not mean carbohydrates must be eliminated or that foods must always be eaten separately; balanced combinations are more practical.
22 What separate contribution does physical activity make in heart disease prevention apart from diet?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. It improves cardiorespiratory fitness and helps control body weight and blood pressure
Explanation: Regular physical activity increases energy expenditure and improves cardiorespiratory fitness. It can support healthy body weight, insulin sensitivity, vascular function, and blood-pressure control, thereby contributing independently to cardiovascular prevention. Reducing saturated fat, increasing dietary fibre, and lowering salt are changes to food, not direct effects of exercise, so options B, C, and D confuse separate interventions.
23 Why is a highly restrictive diet especially concerning in adolescents?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Growth, nutrition and eating behaviour can be affected
Explanation: Adolescence is a period of rapid physical growth, hormonal change, bone development, and increasing nutrient needs. Severe restriction may cause inadequate energy, protein, iron, calcium, vitamins, or other nutrients. It can also encourage unhealthy weight-control practices and disordered eating. A balanced, varied plan with professional guidance is safer than unnecessary elimination of foods.
24 Why should messages in a community nutrition programme not be limited to knowledge only?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Behaviour change and available options are also necessary
Explanation: Knowledge is an important foundation, but people may not change behaviour if healthy food is unavailable or unaffordable, facilities are missing, social norms discourage change, or practical skills are lacking. Effective community programmes combine clear education with supportive environments, accessible choices, counselling, skills, and follow-up. Thus, knowledge should lead to feasible action rather than remain information alone.
25 Why is food safety included in chronic disease prevention?
0 reads0 helpful★ – (0)
Answer and explanation
Correct answer: A. Safe food helps reduce food-borne infections and maintain overall health and nutritional status
Explanation: Food safety includes hand hygiene, clean preparation, adequate cooking, prevention of cross-contamination, safe storage, and appropriate water use. These practices reduce food-borne infections, which can impair nutrient intake and status and complicate management of existing disease. Food safety is therefore part of overall health protection, not merely a way to improve taste or storage.
