Diet therapy

Correct answer: A. When safe alternatives are needed for restricted foods

Explanation: Food alternatives are useful when a therapeutic diet restricts particular foods or nutrients. They allow the patient to substitute an acceptable, affordable, culturally familiar, and nutritionally similar item, improving adherence without violating the prescription. This is an important part of individualized diet counselling.

Correct answer: A. So that the patient follows the diet while therapeutic limits are maintained

Explanation: A therapeutic diet must satisfy medical requirements, such as controlling salt, sugar, fat, fluid, or fibre according to the disease. At the same time, acceptable taste, aroma, texture, and variety encourage the patient to eat the prescribed food regularly. Therefore, flavour should be improved through permitted ingredients and cooking methods without violating therapeutic restrictions. This balance improves adherence while supporting recovery and preventing complications.

Correct answer: A. Because processed foods may also contain hidden sodium

Explanation: Much dietary sodium comes from packaged, processed, preserved, restaurant, and ready-to-eat foods rather than from salt added at the table. Therefore, hypertension management should include reading food labels, limiting pickles, papad, sauces, instant foods, and salty snacks, and following the individualized medical plan. Table-salt reduction alone may miss substantial sodium exposure.

Correct answer: A. Blood phosphorus level and disease stage

Explanation: Healthy kidneys remove excess phosphorus and help regulate mineral balance. In kidney disease, phosphorus may accumulate, particularly when renal function is reduced, and persistent elevation can disturb calcium and bone metabolism and contribute to vascular complications. The need and degree of restriction should therefore be based on laboratory results, kidney function, dialysis status, medications, and the prescribed renal nutrition plan.

Correct answer: A. Allergy may involve an immune response, whereas intolerance may involve digestion or tolerance

Explanation: A food allergy involves an immune response to a food protein and may cause hives, swelling, breathing difficulty, vomiting, or anaphylaxis. Food intolerance generally does not involve the immune system; lactose intolerance, for example, results from inadequate lactase and causes digestive symptoms. Correct identification is essential because allergy can require strict avoidance and emergency planning.

Correct answer: A. Identify the cause and offer acceptable alternatives

Explanation: Food aversion may result from nausea, medication effects, altered taste or smell, pain, anxiety, previous unpleasant experiences, or the disease itself. The nutrition expert should assess the cause, respect preferences, modify flavour, texture, temperature, timing, and presentation, and offer nutritionally equivalent alternatives. This patient-centred approach supports adequate intake without force.

Correct answer: A. When symptoms suggest lactose intolerance

Explanation: Diarrhoea can temporarily reduce the intestinal enzyme lactase, so some patients may develop bloating, cramps or loose stools after milk. Milk should not be stopped automatically; it may be limited briefly only when lactose-intolerance symptoms occur, while fluids, electrolytes and adequate nutrition are maintained.

Correct answer: A. Serve low-odour, cool or room-temperature food

Explanation: Strong food aromas can intensify nausea, particularly during chemotherapy. Cool or room-temperature foods generally release fewer volatile smells than steaming hot foods and may therefore be easier to tolerate. Small portions, ventilation and the patient’s preferences should also be considered while maintaining hydration and nutrition.

Correct answer: A. Control blood glucose while meeting maternal and fetal nutrition needs

Explanation: Gestational diabetes requires control of blood glucose without compromising the energy, protein, vitamins and minerals needed by the mother and developing fetus. Carbohydrates should be distributed and selected wisely rather than eliminated. Meal timing, monitoring, activity and prescribed treatment should be individualized by the healthcare team.

Correct answer: A. The disease, nutrient needs, and tolerance

Explanation: A therapeutic diet is individualized according to the disease condition, nutritional requirements, treatment goals, and the person's tolerance of particular foods. Age, appetite, allergies, cultural preferences, and the ability to chew or digest food may also be considered. Thus, option A gives the medically relevant basis; the other options have no therapeutic importance.

Correct answer: A. To replace foods with similar nutritional value

Explanation: A food exchange list groups foods with broadly similar amounts of energy and key nutrients within a specified exchange portion. A person can substitute one food for another in the same group while maintaining better control of the meal plan. This is useful for variety and for therapeutic planning, including diabetes management, under professional guidance.

Correct answer: A. To improve diet adherence

Explanation: A diet plan is more likely to succeed when it respects a person’s taste, culture, religion, schedule, cooking skills, and usual food habits while still meeting health requirements. Offering acceptable and safe alternatives improves satisfaction and adherence. Personal preference must be balanced with allergies, medical restrictions, and nutritional adequacy.

Correct answer: A. Replacing foods with similar nutritional value

Explanation: A food exchange list groups foods with approximately similar amounts of energy and key nutrients. One food can therefore be replaced by another from the same exchange group without greatly disturbing the planned diet. This supports variety, flexibility and accurate control, especially in therapeutic diets such as diabetic meal planning.

Correct answer: C. Nutrition principles and disease needs

Explanation: Diet therapy is the scientific use of food and nutrients to support the treatment or management of a health condition. It combines principles of nutrition with the patient's disease, symptoms, age, activity, tolerance, and medical requirements. Advertising, kitchen decoration, or food colour cannot provide a therapeutic basis.

Correct answer: B. It helps choose options with similar carbohydrate or energy

Explanation: A food exchange list groups foods with broadly similar amounts of carbohydrate, protein, fat, or energy. It allows a person with diabetes to replace one food with another while keeping the meal plan and carbohydrate distribution reasonably controlled. It supports variety, but it does not replace medical advice or prescribed medicines.

Correct answer: A. Diet therapy modifies balanced-diet principles according to the disease

Explanation: Therapeutic diet planning begins with the principles of a balanced diet but adjusts energy, nutrients, texture, meal timing, or fluid according to the person’s disease, symptoms, treatment, and tolerance. For example, sodium may be limited in some conditions. Such changes should be planned by a qualified professional.

Correct answer: B. Because diet adherence can decrease

Explanation: Food preference affects enjoyment, satisfaction, willingness to continue, and the likelihood of following a diet over time. Ignoring it completely may lead to rejection of the plan, although preferences must still be balanced with safety and therapeutic requirements. A good counsellor offers acceptable alternatives within the prescribed limits.

Correct answer: B. When the person applies correct information in food behaviour

Explanation: Nutrition education is more than the transfer of facts. Its broader purpose is to help people understand nutrition, develop practical skills, make informed choices, and apply suitable knowledge in daily food behaviour. A person who changes food selection, preparation, or eating practices demonstrates application. Merely hearing information without any behavioural change does not show that education has achieved its full purpose.

Correct answer: A. It is modified according to the disease

Explanation: A therapeutic diet usually begins with the principles of a normal balanced diet and then changes one or more features to meet a patient’s condition. Modifications may involve energy, nutrients, fibre, texture, meal frequency or fluid, depending on the disease. The diet should remain adequate, safe and acceptable while supporting medical treatment.

Correct answer: D. Because processed, packaged, and salty foods may contain hidden sodium

Explanation: Total sodium intake comes from more than salt added at the table. Pickles, papad, savoury snacks, sauces, instant foods, bakery products, canned foods, and other packaged items may contain substantial salt or sodium compounds before they reach the plate. Thus a person may reduce visible table salt but still consume a high total amount. Reading labels and limiting processed foods are important parts of sodium control. Therefore, option D is correct.

Correct answer: A. The person can better understand and adopt the plan

Explanation: Shared decision-making combines professional evidence with the person’s preferences, culture, resources, schedule, goals and readiness to change. When people understand the reasons for a plan and help choose realistic options, they are more likely to feel ownership and follow it consistently. The professional still explains risks and therapeutic limits, so shared decision-making is collaboration, not abandonment of expert guidance.

Correct answer: C. Balanced control of carbohydrates and total energy

Explanation: Diabetes diet planning aims to regulate blood glucose through appropriate carbohydrate portions, meal timing, fibre, total energy, and overall food quality. It does not mean eliminating all carbohydrates or skipping meals. The plan should consider medicines, activity, age, preferences, and blood-glucose goals under professional guidance.

Correct answer: B. Controlling energy intake in a balanced way

Explanation: Diet therapy in obesity aims to create a sustainable energy deficit while preserving nutritional adequacy, muscle, and health. It emphasises balanced portions, nutrient-dense foods, appropriate physical activity, behaviour change, and realistic goals. Extreme crash diets are unsafe, difficult to maintain, and may cause nutrient deficiencies or muscle loss.

Correct answer: C. High-energy and high-protein diet

Explanation: Underweight and protein-energy malnutrition commonly require energy-dense and protein-rich foods to support weight restoration, growth, tissue repair, and immune function. Meals may need to be small, frequent, and culturally acceptable. The plan must be gradual and medically supervised when severe malnutrition, infection, or complications are present.

Correct answer: C. Gradually according to the patient’s tolerance

Explanation: After surgery, gastrointestinal function, alertness, nausea, swallowing ability, and the type of operation determine when and how feeding advances. Diet is commonly progressed from appropriate fluids to soft or regular foods as tolerated and as prescribed. Gradual advancement helps detect vomiting, distension, aspiration risk, or poor tolerance.
