Prevention of chronic diseases

Correct answer: A. Vegetables and salad

Explanation: A practical balanced-plate guide places about half the plate in a variety of vegetables and salad. These foods add dietary fibre, vitamins, minerals, water, and relatively few calories, supporting fullness, healthy weight, glucose regulation, and heart health. Grains and protein foods remain important, but they occupy the other portions. Sweets and fried foods should not form the main half of a meal.

Correct answer: A. Unsweetened lemon water or plain water

Explanation: Plain water or unsweetened lemon water contains no added sugar and virtually no saturated fat, making it a heart-friendly beverage choice. Creamy drinks and full-cream milkshakes may supply saturated fat, while sugary drinks can add excess energy and raise triglycerides. A beverage alone cannot cure abnormal cholesterol, but choosing low-sugar, low-saturated-fat drinks supports an overall cholesterol-lowering lifestyle.

Correct answer: A. To identify risk early

Explanation: Blood pressure and blood glucose can remain abnormal for a long time without obvious symptoms. Regular screening helps identify hypertension, prediabetes, or diabetes early, allowing a person and health professional to begin diet, activity, weight-management, monitoring, or treatment measures. Early detection can reduce later complications affecting the heart, kidneys, eyes, nerves, and blood vessels. The other options have no medical connection.

Correct answer: A. A balanced diet low in unhealthy fats and regular activity

Explanation: Family history may increase inherited susceptibility to cardiovascular disease, but it does not make disease unavoidable. A balanced diet with less saturated and trans fat, more fibre-rich foods, regular physical activity, healthy weight, no tobacco, and periodic screening can reduce modifiable risk. Therefore, option A is the appropriate precaution. Fried foods, smoking, and sugary drinks move risk in the opposite direction.

Correct answer: A. It can reduce risk to the heart and blood vessels

Explanation: Tobacco smoke damages the lining of blood vessels, promotes inflammation and clot formation, and can reduce oxygen delivery to the heart. Nicotine also raises heart rate and blood pressure. Quitting smoking lowers these risks over time and benefits both smokers and people exposed to second-hand smoke. It is therefore a major, modifiable step in preventing heart attack, stroke, and other vascular disease.

Correct answer: A. They may be linked with some risk factors

Explanation: Some processed foods, particularly processed meats, are associated with increased risk of certain cancers when consumed frequently. Charring or burning food can form compounds such as polycyclic aromatic hydrocarbons and heterocyclic amines; risk depends on the food, amount, and cooking conditions. Choosing more fresh foods and avoiding heavily burnt portions is a sensible preventive practice. Option A is appropriately cautious because it does not claim that every processed food causes cancer.

Correct answer: A. It can increase the risk of liver disease

Explanation: The liver metabolizes alcohol, and repeated excessive exposure can injure liver cells. It may begin with fatty liver and progress to alcoholic hepatitis, fibrosis, cirrhosis, liver failure, or increased cancer risk. The damage depends on amount, duration, individual factors, and drinking pattern. Alcohol does not strengthen liver regeneration or prevent fat and inflammation, so option A is the only correct answer.

Correct answer: A. To avoid uncontrolled fried and sweet snacks

Explanation: Planning snacks helps a person decide in advance what and how much to eat, rather than choosing high-sugar or fried foods when very hungry. Nutritious options such as fruit, unsweetened curd, roasted gram, nuts in suitable portions, or vegetable pieces can support satiety and nutrient intake. Planned snacks are not meant to replace all meals; they help maintain a balanced eating pattern and control excess energy.

Correct answer: A. To reduce extra sugar and energy

Explanation: Sweetened drinks can provide a large amount of added sugar and energy without creating the same fullness as solid, fibre-rich foods. Frequent intake may contribute to excess calorie consumption, weight gain, dental caries, raised triglycerides, and greater risk of type 2 diabetes. Replacing them with water or unsweetened beverages is a practical preventive step. The purpose is not to remove protein, fibre, or hydration altogether.

Correct answer: A. It helps avoid overeating

Explanation: Recognizing physical hunger and noticing satiety are parts of mindful eating. They help a person begin eating when the body needs food and stop when comfortably satisfied, rather than continuing because of distraction, stress, advertising, or large portions. This can improve portion control and energy balance, although it should not be used to ignore genuine hunger or medical nutritional needs. Therefore, option A is correct.

Correct answer: A. Balanced use of lemon, spices, and herbs

Explanation: Lemon, herbs, garlic, ginger, pepper, and other spices can add aroma, acidity, and flavour without supplying large amounts of sodium. Using them helps people adapt gradually to less salt. Packaged sauces may themselves be high in sodium, while doubling salt or adding excessive sugar shifts the problem rather than creating a balanced diet. Flavouring should be used sensibly and should not replace professional dietary advice for a medical condition.

Correct answer: A. Steaming and boiling

Explanation: Steaming and boiling generally require little or no added fat, so they can help reduce the energy and saturated fat content of a meal when compared with deep frying or cooking in excess ghee. Repeatedly heating oil may also produce undesirable degradation products. The total recipe still matters: excess salt, creamy sauces, and large portions can reduce the benefit. Nevertheless, steaming and boiling are the best choices among the listed methods.

Correct answer: A. Fibre, protein, and micronutrients are obtained

Explanation: Salad and pulses complement one another in a balanced meal. Vegetables and salad can provide fibre, potassium, folate, vitamins, minerals, and protective plant compounds, while pulses provide plant protein, fibre, iron, and other nutrients. Together they support fullness, bowel health, and a varied diet that may reduce chronic-disease risk. They do not provide only fat and cannot eliminate the body’s need for water or other food groups.

Correct answer: A. Sodium, sugar, fat, and ingredient list on the nutrition label

Explanation: The nutrition information panel and ingredient list provide objective information about sodium, added sugar, total fat, saturated fat, fibre, allergens, and serving size. Checking them helps consumers compare products and avoid items that are excessively salty, sugary, or fatty. Marketing claims, package colours, and shop decoration do not reliably indicate nutritional quality. It is also important to check expiry date, storage instructions, and the number of servings in the package.

Correct answer: A. It does not give extra sugar and energy

Explanation: Plain water hydrates the body without adding sugar, fat, or significant calories. Sweetened drinks can contribute substantial added sugar and energy while providing little fibre or satiety, which may promote weight gain, dental caries, and metabolic risk when consumed frequently. Water is therefore usually the better everyday beverage, although individual medical conditions may require specific advice. Option A states the relevant advantage accurately.

Correct answer: A. Reducing sweet drinks and choosing fruits

Explanation: Reducing sugar-sweetened drinks is a practical way to lower added-sugar and calorie intake. Whole fruits can provide natural sweetness together with fibre, water, vitamins, and minerals, which generally makes them more filling than sweets or fruit-flavoured drinks. Portion and overall diet still matter, and fruit juice is not identical to whole fruit. The other options increase added sugar rather than reducing it, so option A is correct.

Correct answer: A. It can support weight and blood pressure control

Explanation: Regular aerobic and muscle-strengthening activity can improve cardiovascular fitness, support healthy body weight, and help the heart and blood vessels work more efficiently. For many people, this contributes to lower or better-controlled blood pressure, especially when combined with lower sodium intake, a balanced diet, adequate sleep, and limited alcohol. Exercise does not remove the need for food or fibre and does not increase dietary salt, so option A is correct.

Correct answer: A. Whole grains, pulses, vegetables, and curd

Explanation: Option A combines several minimally processed food groups: whole grains and pulses provide fibre and plant protein, vegetables supply vitamins, minerals, and protective compounds, and curd can provide protein and calcium. Such variety supports healthy weight, glucose regulation, bowel health, and cardiovascular health when portions and preparation are appropriate. The other choices are commonly high in added sugar, sodium, unhealthy fat, or refined energy and therefore are poorer routine choices.

Correct answer: A. Helps add freshness, dietary variety, and nutrients to the diet

Explanation: Seasonal fruits and vegetables are often fresher, more varied, and easier to obtain during their natural period of availability. They can supply dietary fibre, vitamins, minerals, water, and plant compounds that support digestive, metabolic, and cardiovascular health. They do not replace cereals, pulses, dairy, or other needed food groups, and they do not remove the need to drink water. Most people benefit from including a variety of them in meals.

Correct answer: A. They may cause nutrient deficiencies, muscle loss, and weight regain

Explanation: Crash diets severely restrict calories or exclude important food groups. They may cause deficiencies of protein, vitamins, and minerals, and the body may lose muscle along with fat. Such diets are difficult to sustain, so weight often returns when normal eating resumes. Safe weight management requires gradual, balanced, adequate, and sustainable dietary changes.

Correct answer: A. To identify obesity risk and changes early

Explanation: Regularly checking body weight and waist circumference helps a person notice gradual changes that may otherwise go unnoticed. Increased waist circumference can indicate excess abdominal fat, which is associated with a higher risk of diabetes, hypertension, and cardiovascular disease. Early recognition supports timely lifestyle correction and professional advice.

Correct answer: A. Regular balanced meals, an active life, and timely check-ups

Explanation: Chronic disease prevention is strongest when several healthy behaviours are followed together. Balanced meals supply essential nutrients, regular physical activity supports healthy weight and metabolic function, and timely check-ups can identify risk factors early. Medicines may be necessary for some people, but they cannot replace healthy eating, activity, and screening.

Correct answer: A. To make timely lifestyle improvements

Explanation: Risk factors such as smoking, inactivity, excess salt, unhealthy diet, obesity and family history indicate increased disease probability. Identifying them early allows appropriate diet, activity and medical guidance to begin before complications develop; it does not justify stopping prescribed medicines.

Correct answer: B. Whole grains, pulses, and vegetables

Explanation: A heart-healthy eating pattern emphasises whole grains, pulses, vegetables, fruits, and other minimally processed foods. These foods provide dietary fibre, vitamins, minerals, and protective plant compounds, while generally containing less saturated and trans fat than fried or highly processed foods. Fibre and balanced nutrition support healthy cholesterol, blood pressure, body weight, and blood-vessel function. Therefore, option B is the best choice.

Correct answer: C. It can help appetite and blood sugar control

Explanation: Regular, balanced meal timing can reduce long gaps followed by overeating and may support steadier appetite and blood-glucose management. The benefit also depends on suitable portions, fibre-rich foods and overall activity. Meal timing alone cannot prevent every case of diabetes.
