Prevention of chronic diseases

Correct answer: D. Total energy intake may increase, raising the risk of weight gain

Explanation: Choosing an unsaturated oil may be preferable to using trans-fat-rich or repeatedly heated fats, but all edible oils are energy-dense. Fat provides about 9 kcal per gram, so excessive quantity can raise total energy intake even when the oil is considered healthy. Portion size, cooking method, and the overall dietary pattern must be considered together for weight and disease prevention.

Correct answer: B. Salt, sugar, fat, and nutrient quality

Explanation: Calories describe energy but do not show the complete nutritional quality of a product. A food with similar calories may differ greatly in sodium, added sugar, saturated fat, fibre, protein, vitamins, and degree of processing. Consumers should examine serving size, ingredients, and the nutrient table rather than relying on one number. This supports better choices for chronic disease prevention.

Correct answer: C. Stress management and portion control

Explanation: Stress-related overeating can increase total energy intake and may favour high-sugar or high-fat foods. Simply skipping later meals can worsen hunger and promote another episode of overeating. A better approach includes identifying triggers, practising stress-management techniques, planning balanced meals, eating mindfully, and using reasonable portions. Persistent distress or loss of control warrants professional support.

Correct answer: A. Increase whole grains, pulses, fruits, and vegetables

Explanation: Whole grains, pulses, fruits, and vegetables are important sources of dietary fibre. Fibre adds bulk to stool, supports regular bowel movement, promotes fullness, and may help with weight and metabolic health. The increase should be gradual with adequate fluids, particularly if the person previously ate very little fibre. Refined grains and strained juices generally provide much less fibre.

Correct answer: B. Take health counselling and make a behaviour plan

Explanation: Screening is useful only when its findings are understood and acted upon. A health professional can explain values, identify modifiable risks, clarify whether follow-up is needed, and help create realistic goals for diet, activity, medication, or further testing. The person should not self-diagnose or stop treatment based on an isolated report. Counselling converts information into preventive behaviour.

Correct answer: C. Check hidden sodium in packaged soup

Explanation: Reducing an obvious salty food such as pickle may not lower total sodium intake if other processed foods remain high in sodium. Packaged soups can contain considerable salt, flavour enhancers, and preservatives even when they do not taste extremely salty. The ingredient list and nutrition panel should be checked, serving size should be considered, and lower-sodium alternatives or homemade soup may be preferable.

Correct answer: D. Choose local pulses, whole grains, and seasonal vegetables

Explanation: A nutritious diet does not require expensive imported products or branded health foods. Local pulses, whole grains, seasonal vegetables, fruits, eggs, and other affordable foods can provide protein, fibre, vitamins, and minerals. Planning meals, buying seasonal produce, using leftovers safely, and limiting packaged snacks can control cost while improving diet quality. Practical affordability improves long-term adherence.

Correct answer: A. They provide more dietary fibre and can help increase satiety

Explanation: Whole grains retain the bran and germ in addition to the endosperm, so they generally provide more fibre, vitamins, minerals, and beneficial plant compounds than refined flour. Fibre supports digestion, promotes satiety, and can moderate the speed of glucose absorption. Portion size and preparation still matter, but replacing some refined grains with whole grains is a useful preventive change.

Correct answer: B. Use the plate method and practise portion control

Explanation: Portion control helps a person understand and regulate energy intake without requiring complete avoidance of nutritious foods. The plate method commonly encourages a substantial share of vegetables, a suitable portion of protein-rich food, and a measured portion of whole grains or other carbohydrates. Eating slowly, using standard serving utensils, and monitoring weight can support gradual, sustainable change.

Correct answer: C. Because regularity and consistency are necessary

Explanation: Chronic disease risk develops over time, so prevention depends on repeated habits rather than an isolated healthy day. Consistent improvement in food quality, portion size, activity, sleep, tobacco avoidance, and appropriate screening has a greater effect on long-term health. A single healthy meal is still positive, but it cannot compensate for an otherwise harmful pattern maintained over weeks, months, or years.

Correct answer: D. Calcium, vitamin D, and weight-bearing activity

Explanation: Bone health depends on adequate nutrients as well as mechanical stimulation. Calcium supports the mineral structure of bone, vitamin D helps calcium absorption and bone metabolism, and weight-bearing activity stimulates bone and muscle strength. Sources and supplements should be chosen according to age, diet, health status, and professional advice. Tobacco and excessive sugary drinks do not protect bones.

Correct answer: B. Total sodium intake may still increase

Explanation: Blood-pressure prevention depends on total sodium intake from cooking, table salt, packaged foods, pickles, sauces, snacks, and other sources. Adding salt after cooking can offset the reduction made during preparation, particularly when the habit is repeated daily. The person should taste food before salting, read labels, choose fresh foods more often, and use herbs, spices, or lemon for flavour where appropriate.

Correct answer: C. Stress management, a regular sleep routine, and regular meals

Explanation: Stress can disturb sleep, appetite, meal timing, and physical activity. Therefore, a broad correction should address stress management along with a regular sleep schedule and timely, balanced meals. This approach improves several connected lifestyle behaviours instead of trying to solve only one symptom. Sweet drinks, smoking, or stopping exercise can worsen long-term health and do not provide a suitable preventive strategy.

Correct answer: D. Salt, sugar, fat, and trans fat

Explanation: Frequent packaged-snack consumption requires checking salt or sodium, total sugar, total fat, and trans fat together. Excess amounts may contribute to hypertension, excess weight, diabetes, and cardiovascular disease. Calories and protein alone do not reveal the complete health impact. The serving size and number of servings in the packet should also be checked before judging the product.

Correct answer: A. Reducing one risk while increasing another

Explanation: Chronic-disease prevention requires a balanced pattern rather than focusing on only one nutrient. Reducing added sugar may be helpful, but replacing it with excessive salty foods can increase sodium intake and contribute to high blood pressure. Salt, sugar, fat, portion size, activity, and overall diet quality should be considered together. Thus, option A correctly identifies the mistake.

Correct answer: B. Check total sugar, added sugar, and energy per serving on the label

Explanation: Packaged juice may contain naturally occurring fruit sugar, added sugar, and considerable energy. A person at risk of diabetes should read total sugar, added sugar, energy, and serving size before deciding how much to drink. A front-of-pack claim such as “100% fruit” does not mean the beverage is sugar-free or suitable in unlimited amounts. Water and whole fruit may often be better choices.

Correct answer: D. Because inactivity throughout the day should also be reduced

Explanation: A planned evening workout is beneficial, but long uninterrupted sitting during the remaining hours can still contribute to poor metabolic health, stiffness, and reduced daily energy expenditure. Prevention therefore includes breaking up sitting with short walking or stretching breaks, standing when possible, and maintaining regular activity across the day. Exercise should complement, not excuse, prolonged inactivity.

Correct answer: A. Adopt portion control and a balanced plate

Explanation: A very large meal can provide excessive energy and may cause discomfort or post-meal sluggishness, although sleepiness can have several causes. Portion control, slower eating, a balanced plate with vegetables and protein, and regular meal timing are sensible preventive steps. The other options increase excess energy or disturb the routine and therefore do not address the underlying dietary issue.

Correct answer: A. Food-based fibre and varied micronutrients

Explanation: Fruits and vegetables provide dietary fibre, vitamins, minerals, water, and many protective plant compounds in a whole-food matrix. Supplements may be useful for a diagnosed deficiency under professional advice, but they do not fully replace the variety, fibre, texture, and food interactions supplied by whole foods. Prevention therefore requires improving food diversity rather than relying only on pills or powders.

Correct answer: A. Difficulty controlling food intake

Explanation: Skipping breakfast may lead to intense hunger by lunchtime, making portion control more difficult and encouraging rapid or excessive eating. If this pattern is repeated, it can contribute to excess daily energy intake and weight gain, although individual responses vary. Regular, balanced meals with fibre and protein can support better appetite control. Skipping a meal does not automatically increase fibre or improve sleep.

Correct answer: B. Weight, food habits, and activity records

Explanation: Recording weight trends, food habits, and physical activity gives a broader picture of behaviours that influence chronic-disease risk. Such records can reveal frequent sugary drinks, large portions, missed meals, or insufficient movement and help a person set measurable goals. Monitoring is useful when followed by realistic correction; it is not a substitute for professional assessment when symptoms or disease are present.

Correct answer: C. Teach low-oil cooking methods and portion control

Explanation: Family-based prevention works best when the household changes its normal food environment. Steaming, grilling, baking, boiling, or shallow sautéing can reduce excess oil, while portion control limits total energy intake. Vegetables should remain part of the balanced diet. Doubling oil and avoiding health discussions worsen risk, so teaching practical skills to all family members is the best correction.

Correct answer: D. Tobacco can increase serious risks independently of body weight

Explanation: Tobacco exposure can damage the lungs and cardiovascular system and is associated with cancers, stroke, and other serious diseases. These risks are not removed by being thin, physically active, or having a normal body-weight measurement. Weight is only one health factor; avoiding tobacco and seeking cessation support are important preventive actions for every person.

Correct answer: A. Total weekly energy balance can be affected

Explanation: Energy balance reflects total intake and expenditure over time, not simply the number of days that appear healthy. Large amounts of food, sugary drinks, or alcohol on two days can create a weekly energy surplus and reduce the benefit of balanced eating on the other days. Regularity, portion control, and the overall pattern are therefore important for weight and chronic-disease prevention.

Correct answer: B. Use lemon, spices, and herbs with less salt

Explanation: Reducing salt is more sustainable when flavour is maintained with lemon, garlic, herbs, spices, vinegar, or other low-sodium seasonings. Gradual reduction also allows taste preferences to adapt. Packaged salty snacks and extra salt can raise sodium intake and contribute to high blood pressure. The goal is not to stop eating, but to prepare tasty, varied food with less salt.
