Prevention of chronic diseases

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
