Prevention of chronic diseases

Correct answer: A. Balanced and varied

Explanation: A balanced and varied diet supplies carbohydrates, proteins, healthy fats, vitamins, minerals, and fibre in suitable proportions. Variety helps prevent dependence on one type of food, while limiting excessive sugar, salt, and fried foods supports healthy weight and lowers chronic-disease risk.

Correct answer: B. Vitamins and dietary fibre are obtained

Explanation: Fruits commonly provide vitamins, minerals, water, and dietary fibre. Fibre supports bowel function and fullness, while micronutrients support normal body processes. Fruits are protective foods within a balanced diet, but they do not supply every nutrient or replace grains, pulses, milk, and other food groups.

Correct answer: C. Risk of chronic diseases

Explanation: Green leafy vegetables supply fibre, folate, vitamin K, vitamin C, carotenoids, and several minerals. As part of a varied diet, these nutrients support digestion, blood health, and overall wellness. Their regular inclusion may help lower the risk of some chronic diseases, although no single food prevents every disease.

Correct answer: D. High blood pressure

Explanation: Excess sodium can contribute to fluid retention and increased blood pressure, especially in salt-sensitive people. Reducing highly salted foods and choosing fresh foods can support blood-pressure control. Salt reduction is not a complete cure or guarantee, but it is an important dietary measure for preventing and managing hypertension.

Correct answer: A. Whole wheat chapati

Explanation: Whole-wheat chapati is made from grain that retains more of the bran and germ than refined flour. Consequently, it generally supplies more dietary fibre and micronutrients, which support digestion, fullness, and healthier blood-glucose control. Soda, chips, and sweets are not whole-grain foods.

Correct answer: B. Obesity

Explanation: Insufficient physical activity reduces the amount of energy used by the body. If food intake remains high, the excess energy may be stored as fat, increasing the likelihood of overweight and obesity. Regular movement also supports heart fitness, muscles, insulin sensitivity, and prevention of several chronic conditions.

Correct answer: C. Diabetes and weight gain

Explanation: Sugar-sweetened packaged drinks can provide a large amount of added sugar and energy without much fibre or satiety. Frequent intake may contribute to excess calorie consumption, weight gain, insulin resistance, and a higher risk of type 2 diabetes. Water or unsweetened drinks are generally better everyday choices.

Correct answer: C. Heart disease and obesity

Explanation: Highly fried foods are often energy-dense and may contain large amounts of saturated fat, trans fat, or repeatedly heated oil. Frequent excessive intake can promote weight gain and unhealthy blood-lipid levels, thereby increasing cardiovascular risk. Fibre-rich foods, water, and less-oily cooking are better choices for regular meals.

Correct answer: A. Keeping food quantity controlled

Explanation: Portion control means being aware of how much food is served and eaten at one time. It helps regulate total energy intake without requiring a person to skip every meal or avoid all foods. Appropriate portions, combined with food variety and activity, can support healthy weight and chronic-disease prevention.

Correct answer: B. To reduce risk of heart and lung diseases

Explanation: Tobacco smoke contains many harmful chemicals that damage blood vessels and lung tissue. Smoking increases the risk of coronary heart disease, stroke, chronic lung disease, and several cancers. Avoiding smoking, and avoiding second-hand smoke where possible, is therefore an important part of chronic-disease prevention.

Correct answer: C. Pulses and vegetables

Explanation: Pulses and vegetables provide dietary fibre along with vitamins, minerals, and other useful nutrients. Fibre supports normal bowel movement, helps maintain fullness, and can assist healthy blood-glucose and cholesterol control. Sweet drinks and sugar provide little or no fibre, while fried papad is not a dependable fibre-rich choice.

Correct answer: D. Energy and fat intake will be controlled

Explanation: Oils are energy-dense, so even a small quantity contributes substantial calories. Measuring oil and limiting unnecessary additions can help control total fat and energy intake, support healthy body weight, and reduce excessive saturated-fat consumption. Oil should not be eliminated completely because some dietary fat is needed for health.

Correct answer: A. Healthy low-fat cooking method

Explanation: Steaming cooks food through the heat of water vapour rather than immersing it in oil. Because little or no added fat is usually required, steaming helps retain the natural character of many foods while keeping calorie and fat additions low. It is therefore a healthy low-fat cooking method.

Correct answer: B. Salt, sugar and fat

Explanation: Many highly processed packaged foods contain substantial added salt, sugar, and fat to improve taste, texture, or shelf life. Regularly eating such foods can increase energy intake and may contribute to obesity, hypertension, diabetes, and cardiovascular risk. Reading labels and choosing minimally processed foods can help.

Correct answer: D. Healthy lifestyle

Explanation: Adequate, regular sleep supports physical repair, brain function, mood, immune activity, and hormonal regulation. Poor sleep may affect appetite, stress, concentration, and metabolic health. Therefore, sufficient sleep belongs to a healthy lifestyle along with balanced nutrition, physical activity, and avoidance of tobacco.

Correct answer: A. Regular exercise and relaxation

Explanation: Regular physical activity and relaxation practices can reduce muscle tension, improve mood, and support healthier stress responses. Helpful approaches may include walking, breathing exercises, yoga, hobbies, adequate sleep, and talking with a trusted person. Smoking, meal skipping, and excess sugary drinks do not provide healthy long-term stress management.

Correct answer: B. To detect high blood pressure early

Explanation: High blood pressure may develop without obvious symptoms, so a person can feel well while vascular damage is occurring. Regular measurement helps identify raised pressure early and encourages timely lifestyle changes, follow-up, or treatment. Early detection can reduce the risk of stroke, heart disease, kidney disease, and other complications.

Correct answer: C. Diabetes

Explanation: Blood glucose testing measures the amount of sugar in the blood and is used to screen for, diagnose, or monitor diabetes. Persistent high blood glucose can damage blood vessels, nerves, eyes, kidneys, and the heart. Testing alone is not a cure, but early identification supports medical advice and effective management.

Correct answer: D. By helping adopt healthy food and activity

Explanation: Family members can influence the home food environment, encourage physical activity, share healthy routines, and provide emotional support. Such cooperation makes healthy choices easier to maintain and can improve adherence over time. Family support does not mean forcing food or stopping exercise; it means practical, respectful encouragement.

Correct answer: A. Fruit and roasted gram

Explanation: Fruit and roasted gram can provide fibre, vitamins, minerals, and plant protein without the large amount of oil, salt, or trans fat commonly found in fried or highly processed snacks. As part of a balanced diet, such a choice supports healthier weight and blood-lipid patterns, helping reduce cardiovascular risk.

Correct answer: B. Heart health

Explanation: Trans fats can raise LDL cholesterol and lower HDL cholesterol, producing an unfavourable blood-lipid profile. Regularly consuming them increases cardiovascular risk, so limiting foods containing partially hydrogenated oils is beneficial for heart health. This recommendation is part of a broader diet that also controls saturated fat, salt, and excess calories.

Correct answer: C. For calcium and protein

Explanation: Milk and curd commonly provide calcium and high-quality protein, along with other nutrients such as phosphorus and, when fortified, vitamin D. Calcium and protein support bones, teeth, muscles, and growth. The amount of fat varies by product, so low-fat choices may be suitable when total fat intake must be controlled.

Correct answer: D. Bone health

Explanation: Calcium provides the main mineral structure of bones, while vitamin D helps the intestine absorb calcium and supports bone mineralisation. Adequate amounts of both nutrients help maintain strong bones and teeth and reduce the risk of poor bone development and fragility. Therefore, bone health is the only appropriate answer.

Correct answer: A. It helps reduce health risks

Explanation: Excessive alcohol intake can increase the risk of liver disease, some cancers, high blood pressure, injuries, dependence, and poor nutritional status. Avoiding or limiting alcohol is therefore an important preventive health measure. It does not provide fibre, guarantee better nutrition, or replace physical activity.

Correct answer: B. Cancer and heart disease

Explanation: Tobacco smoke contains nicotine and many toxic chemicals that damage blood vessels, the heart, and body tissues. Tobacco use is strongly associated with cancers, coronary heart disease, stroke, and respiratory illness. Avoiding tobacco is therefore a major step in preventing chronic disease; it does not improve digestion, fibre intake, or sleep.
