Prevention of chronic diseases

Correct answer: A. Because total energy, fibre, meal timing and activity also affect risk

Explanation: Option A is correct because diabetes risk depends on the overall pattern of energy intake, carbohydrate quality, fibre, portions, meal timing, physical activity, body weight, and beverage choices. Reducing added sugar can help, but it cannot compensate for excess total energy, refined carbohydrates, inactivity, or frequent overeating. Whole-pattern counselling supports realistic and sustained metabolic improvement.

Correct answer: C. Support in blood lipid and weight control

Explanation: Option C is correct because limiting saturated and trans fats can improve the quality of dietary fat and support healthier blood-lipid levels, while fibre-rich foods improve fullness and may help regulate energy intake and cholesterol handling. Together, these changes support weight management and cardiovascular health, although they complement rather than replace medical care when treatment is required.

Correct answer: D. Because sodium may be hidden in packaged sauces, savoury snacks, and ready-to-eat foods

Explanation: Option D is correct because sodium is often added to packaged sauces, savoury snacks, instant foods, breads, preserved items, and ready-to-eat meals for flavour or preservation. Such foods may not taste extremely salty, so taste alone is unreliable. High sodium intake can contribute to raised blood pressure in susceptible people; reading labels and choosing fresh, minimally processed foods helps reduce exposure.

Correct answer: A. Whole grains can help with fibre, micronutrients and satiety

Explanation: Option A is correct because whole grains retain more of the bran and germ, which provide dietary fibre, vitamins, minerals, and other beneficial compounds. Their structure can slow digestion and improve satiety, supporting blood-glucose regulation and weight control. Refined grains lose much of this structure during processing. Whole grains are beneficial within an appropriate, balanced diet, not as an unlimited food.

Correct answer: A. To identify emotional eating and habit triggers

Explanation: Option A is correct because recording time, situation, feelings, and reasons reveals patterns that a simple food list may miss. A person may eat in response to stress, boredom, social pressure, fatigue, television, or easy availability rather than physical hunger. Recognising these triggers allows counselling to target practical alternatives, mindful eating, portions, routines, and emotional support.

Correct answer: A. Because environment can make healthy choices easier

Explanation: Option A is correct because individual knowledge is difficult to apply when healthier foods are unavailable, unaffordable, inconvenient, or socially unsupported. Schools, workplaces, markets, and community programmes can improve access to safe water, fruits, vegetables, pulses, and balanced meals while reducing the prominence of unhealthy choices. Environmental support makes healthy behaviour more feasible, equitable, and sustainable.

Correct answer: A. Because family risk can be identified early and reduced

Explanation: Option A is correct because family history may indicate increased susceptibility, but it does not make disease inevitable. Appropriate screening can detect raised blood pressure, glucose, lipids, or other early changes before serious complications develop. At the same time, balanced eating, physical activity, healthy weight, adequate sleep, and avoidance of tobacco can reduce modifiable risk and support earlier intervention.

Correct answer: B. Use of local affordable pulses, millets and seasonal vegetables

Explanation: Option B is correct because a preventive diet must be nutritious, affordable, culturally acceptable, locally available, and realistic for the family. Pulses provide protein and fibre, millets and other whole grains provide energy and nutrients, and seasonal vegetables supply vitamins, minerals, and protective compounds. Planning around local foods supports regular use and avoids dependence on expensive or highly processed products.

Correct answer: A. Energy surplus and weight gain

Explanation: Option A is correct because sweetened drinks can add substantial sugar and energy without creating the same fullness as solid, fibre-rich foods. Low physical activity reduces energy expenditure, so the combination can produce a repeated energy surplus and promote weight gain. Over time, excess weight may increase the risk of insulin resistance, type 2 diabetes, hypertension, and other chronic conditions.

Correct answer: A. To improve adherence and sustainable change

Explanation: Option A is correct because a nutrition plan is effective only when the person can and will follow it. Including preferences, culture, budget, cooking skills, and available foods allows healthier substitutions without unnecessary deprivation. This improves acceptability, motivation, adherence, and long-term sustainability. Preferences do not mean ignoring medical needs; they are incorporated within safe, evidence-based limits.

Correct answer: A. Fruit and a small amount of unsalted nuts

Explanation: Option A is correct because fruit provides fibre, water, vitamins, and minerals, while a small portion of unsalted nuts provides protein, unsaturated fats, and satiety. Replacing deep-fried snacks and trans-fat-rich products can improve overall fat quality and reduce excess energy intake. Portion size remains important because nuts are nutritious but energy-dense, and individual medical advice should be followed.

Correct answer: A. Sleep can affect appetite-regulating hormones, metabolism and eating behaviour

Explanation: Option A is correct because inadequate or poor-quality sleep can influence appetite-regulating hormones, energy metabolism, mood, and food-choice behaviour. Sleep loss may increase cravings for energy-dense, sugary, or fatty foods and may reduce motivation for activity. These effects can contribute to obesity and metabolic risk. Sleep counselling therefore complements, but never replaces, a balanced diet and physical activity.

Correct answer: A. Stress can affect uncontrolled eating and blood pressure

Explanation: Option A is correct because persistent stress can influence the nervous and hormonal systems, raise blood-pressure responses, disturb sleep, and promote emotional or uncontrolled eating. Some people respond by choosing high-sugar or high-fat foods and becoming less active. Stress-management skills such as relaxation, regular activity, social support, adequate sleep, and professional help when needed can support healthier prevention, although they do not replace medical care.

Correct answer: A. It can make high-sugar, high-salt and high-fat foods attractive

Explanation: Option A is correct because advertising, packaging, brand characters, promotions, and digital marketing can shape children’s preferences, requests, and perceptions of what is normal or desirable to eat. Marketing often makes highly processed foods rich in sugar, salt, or unhealthy fat appear attractive. Nutrition education, media literacy, parental guidance, and supportive food environments help children evaluate such messages and make healthier choices.

Correct answer: A. Whole fruit provides fibre, takes longer to chew, and promotes satiety

Explanation: Option A is correct because whole fruit retains its natural fibre and physical structure. Fibre and chewing can slow eating, support satiety, and moderate the rate at which carbohydrate is digested and absorbed. Juice usually contains less fibre and can be consumed quickly in a larger amount, making a rapid sugar and energy load more likely. Whole fruit does not completely block glucose absorption, so option C is false.

Correct answer: A. Calorie-controlled diet, reduced salt intake, regular physical activity, and monitoring of weight and blood pressure

Explanation: When obesity and hypertension coexist, the plan should address both energy balance and blood-pressure risk. A balanced calorie-controlled diet, reduced sodium, regular activity, gradual weight loss when appropriate, and monitoring can work together. Skipping meals is unsafe and difficult to sustain, while exercise alone or continued salty processed foods fails to address all major risk factors. Individual medical guidance remains important.

Correct answer: A. Prescribing medicine without qualification

Explanation: Prescribing medicines without the required legal qualification exceeds the usual scope of a dietitian and may endanger the patient. A dietitian should provide nutrition assessment and counselling within authorised competence, document concerns, and refer or coordinate with a physician when medication or medical diagnosis is needed.

Correct answer: A. Because diet can reduce disease risk through healthy habits

Explanation: Diet influences body weight, blood pressure, blood glucose, blood lipids, and overall cardiometabolic risk. Appropriate dietary patterns, physical activity, and early counselling can help prevent or delay several chronic conditions, although they do not replace medical care. Thus, option A correctly explains the preventive scope.

Correct answer: B. With healthy eating guidelines, awareness, and policy support

Explanation: At population level, nutrition contributes through dietary guidelines, public education, supportive food environments, surveillance, and policies that improve access to healthy and safe foods. These strategies can reduce exposure to major risk factors for chronic disease and help people make informed choices. They are broader than individual taste and do not involve removing food safety, so option B is correct.

Correct answer: A. Through continuous counselling, monitoring and lifestyle modification

Explanation: Chronic diseases usually require sustained dietary and lifestyle support rather than a single instruction. The professional assesses progress, reinforces achievable goals, monitors adherence and coordinates with the medical team. Plans may be adjusted as the patient’s condition, laboratory results or circumstances change. Medication prescribing remains outside this nutrition role. Hence, option A is correct.
