Diet therapy

The success of diet therapy should be assessed through meaningful outcomes rather than cost or appearance. A suitable plan is followed by the patient and produces improvement in relevant indicators such as weight, blood glucose, blood pressure, symptoms or laboratory values. Adherence and clinical response together make option A the most balanced measure.

Dietary fibre, particularly soluble fibre, can slow digestion and the absorption of carbohydrate. This may reduce the rapid rise in blood glucose after a meal and can also support satiety and bowel health. Fibre does not replace diabetes medicines and does not always affect blood pressure in the stated way. Therefore, option B is the accurate explanation.

Energy density means the amount of energy supplied by a given weight or volume of food. Adding milk and nut powder to porridge increases calories and nutrients without greatly increasing the volume, which is useful for a patient with poor appetite or increased requirements. Water dilutes food, removing oils lowers energy, and halving the portion is inappropriate. Hence C is correct.

A liquid diet may provide insufficient calories, protein, vitamins or minerals if it is used for a prolonged period or is poorly planned. The patient may also receive inadequate fluid, especially when intake is restricted by nausea or illness. Intake, output, duration and nutrient adequacy should therefore be monitored. Dehydration and nutrient deficiency are the clinically important risks, making D correct.

Avoiding extra salt at the table is a practical way to reduce sodium intake. However, a complete low-sodium plan also requires checking hidden sodium in pickles, packaged snacks, canned soups, sauces and processed foods. Option B is the only behaviour that reduces added salt; the other choices commonly supply substantial sodium. Therefore, B is correct.

Organ meats such as liver, kidney and brain contain high amounts of purines. Their breakdown can increase uric acid, which may contribute to gout attacks in susceptible people. Plain rice, apples and milk are not typical high-purine choices in this comparison. A low-purine plan must still be individualized, but organ meat is the clear answer. Therefore, D is correct.

Sugar-sweetened drinks can supply a large amount of rapidly absorbed carbohydrate without creating much fullness. They may therefore raise blood glucose quickly and add unnecessary energy. Choosing an unsweetened beverage reduces this extra sugar load, although the overall meal plan and medication still matter. It does not remove protein or stop digestion. Thus, B is correct.

Fever and infection may increase metabolic demands and promote tissue breakdown. Adequate, good-quality protein supplies amino acids needed for tissue repair, immune proteins and preservation of muscle mass. The exact amount depends on age, kidney function, illness severity and tolerance, and should be combined with adequate energy. Therefore, D is correct.

After diarrhoea, the intestine may remain sensitive, so food should be reintroduced gradually according to tolerance. Rehydration with suitable fluids and oral rehydration solution is important, while light, easily digested foods can be advanced step by step. Fried foods and excess sugar may worsen symptoms, and stopping fluids is unsafe. Thus, A is correct.

Mouth sores can make chewing and swallowing painful, especially when food is acidic, spicy, salty, rough or very hot. Soft, moist and mild foods are usually easier to tolerate and may help maintain energy and protein intake during cancer treatment. The patient should also follow clinical advice about oral care and food safety. Therefore, option B is correct.

Empty-calorie foods provide substantial energy, often from added sugar or solid fat, but little protein, fibre, vitamins or minerals. Frequent consumption can make it difficult to achieve an energy deficit and may displace nutrient-rich foods. Replacing them with vegetables, whole grains, pulses and other nutrient-dense choices supports healthier weight control. Thus, A is correct.

Small, frequent meals can provide repeated opportunities to obtain energy and protein without making the patient face a large, uncomfortable portion. They may be easier to tolerate when appetite is poor, fatigue is present or early fullness occurs. Meals should still be nutrient-dense and planned around the patient’s medical needs. Therefore, option B is the most suitable pattern.

When kidney function is impaired, phosphorus may accumulate because excretion is reduced. Depending on laboratory results and the treatment plan, foods with high phosphorus or phosphate additives may need to be limited. The diet should remain nutritionally adequate, and restrictions must be individualized with medical and dietetic advice. Therefore, high-phosphorus foods in option C are correct.

Safe weight loss should reduce excess energy gradually while supplying adequate protein, fibre, vitamins, minerals and fluids. Balanced meals, portion awareness, physical activity where appropriate and regular monitoring make the plan more sustainable. Extreme crash diets, eliminating whole food groups without reason and sweet-drink-only plans can cause deficiency or poor adherence. Hence D is correct.

Respecting religious and cultural food practices helps build trust and makes the therapeutic plan more acceptable and realistic. When patients can follow foods consistent with their beliefs, adherence and long-term participation often improve. The dietitian must still check nutrient adequacy, allergies and medical restrictions. This respectful, individualized approach makes option A correct.

Children need nutrients not only for recovery from illness but also for normal growth, brain development, activity and tissue building. A therapeutic diet must therefore meet age-specific energy, protein, vitamin and mineral needs while respecting the disease-related restriction. Excessive restriction can impair growth, so monitoring and professional guidance are important. B is correct.

Measuring food quantity helps the patient follow the prescribed portion size accurately. It allows the dietitian to estimate energy, protein, carbohydrate, fat, vitamins, and mineral intake, compare actual intake with requirements, and make suitable adjustments. It supports portion control but does not cure every disease by itself.

A person with lactose intolerance may have digestive symptoms after consuming ordinary milk because lactose is not adequately digested. Depending on individual tolerance, curd or yoghurt, lactose-free milk, or another calcium-rich alternative may be selected. The choice should preserve nutrition without forcing the problem food.

Laboratory tests provide objective information that cannot always be obtained from a food history alone. Blood glucose, haemoglobin, serum proteins, lipid levels, electrolytes, and kidney-function results can help assess nutritional status, identify problems, monitor disease control, and guide safe dietary modification.

Burn injuries damage skin and other tissues and may increase metabolic rate and protein breakdown. Adequate high-quality protein supplies amino acids needed for immune function, formation of new tissue, collagen production, and wound healing. Energy and fluids must also be planned according to clinical need.

Skipping meals can make blood-glucose levels fluctuate, especially when a person uses insulin or medicines that stimulate insulin release. It may cause low blood glucose, excessive hunger, overeating later, or poor overall control. Regular, balanced meals help coordinate carbohydrate intake with treatment.

Diet planning in gestational diabetes must maintain adequate energy and nutrients for the pregnant woman and growing fetus while avoiding excessive rises in blood glucose. Regular meals and snacks, appropriate carbohydrate portions, fibre-rich foods, and monitoring are important. Severe restriction or removal of essential foods is unsafe.

Steaming and grilling generally require little or no added oil, so they can reduce the fat and energy content of a meal compared with deep frying. Baking, boiling, or pressure-cooking may also be suitable. The total recipe, portion size, and the patient’s prescribed therapeutic plan should still be considered.

Many fruits and vegetables provide potassium, fibre, antioxidants, and other nutrients and are naturally low in sodium when prepared without added salt. They fit heart-healthy eating patterns such as DASH. They do not replace prescribed medicines, and the overall diet must also control sodium and portions.

Cross-contamination occurs when an allergenic food or its residue reaches food that should be safe, for example through shared knives, boards, pans, hands, or storage containers. Some allergic individuals react to very small quantities, so careful cleaning, separation, label reading, and communication are essential for safety.
