Regular diet and modified diets

Correct answer: B. Salty pickle

Explanation: Salty pickles commonly contain a large amount of added salt, whose main mineral is sodium. They are therefore restricted in a low-sodium diet, especially for people with hypertension, fluid retention, or certain heart and kidney conditions. Fresh banana, plain rice, and unsalted lentils are generally much lower in sodium when no extra salt is added.

Correct answer: B. Balanced calorie control

Explanation: A low-energy diet reduces total calorie intake while continuing to provide adequate protein, vitamins, minerals, fibre, and other essential nutrients. Balanced calorie control is safer and more effective than crash dieting or stopping food. Sweets add concentrated calories, and doubling salt has no benefit for energy control and may harm health.

Correct answer: C. Carbohydrate and meal timing

Explanation: Carbohydrate quantity, distribution, food quality, and meal timing influence blood-glucose levels, so they are important in a diabetes meal plan. Regular balanced meals and appropriate portions can help avoid sharp rises or falls in glucose. The exact plan depends on medicines, activity, age, and medical advice; plate decoration and room light are irrelevant.

Correct answer: D. Excess fat and fried food

Explanation: For many heart conditions, excess saturated fat, trans fat, fried foods, and excessive calories may be limited to support healthier blood lipids and body weight. The exact prescription depends on the diagnosis and clinician’s advice. Fibre, water, and vitamins are not automatically removed; they are usually encouraged in suitable amounts unless another condition requires restriction.

Correct answer: A. For nutrient and mineral control

Explanation: Diseased kidneys may not remove metabolic waste and excess minerals efficiently. Depending on kidney function and treatment, protein, sodium, potassium, phosphorus, fluid, or energy may need careful adjustment. The prescription must be individualised by a qualified health professional because requirements differ between stages of disease and dialysis. Colour and decoration have no therapeutic role.

Correct answer: B. Celiac disease

Explanation: In coeliac disease, gluten proteins in wheat, barley, and rye trigger an immune reaction that damages the lining of the small intestine. Strict avoidance of gluten is the established dietary treatment and supports intestinal healing. Crohn’s disease, iron-deficiency anaemia, and hypertension may require other dietary measures, but gluten avoidance is not their defining treatment.

Correct answer: C. Tolerance to milk sugar

Explanation: Lactose is the natural sugar in milk and many dairy products. A lactose-modified diet reduces lactose or uses lactose-free alternatives for people who cannot digest it adequately and develop symptoms such as bloating, cramps, or diarrhoea. It is different from low-sodium, low-purine, and low-fat diets, which modify other dietary components.

Correct answer: D. Giving small, frequent meals

Explanation: Meal frequency means how many times a person eats during the day. Giving small, frequent meals increases the number of eating occasions while keeping each serving relatively small. This modification may help a person with poor appetite, weakness, early fullness, or difficulty eating a large meal. Therefore, option D is correct; the other options do not modify meal frequency or the diet itself.

Correct answer: B. To provide vitamins, minerals, and fibre

Explanation: Fruits and vegetables are important because they supply vitamins, minerals, dietary fibre, water, and many protective plant compounds. These nutrients support immunity, digestion, growth, and general health. They do not primarily provide salt or oil, and their inclusion makes a regular diet more varied and nutritionally adequate.

Correct answer: C. Energy

Explanation: Cereals such as rice, wheat, maize, and millet are rich in carbohydrates, which are the body’s major source of energy. They also provide some protein, fibre, vitamins, and minerals, especially when whole grains are used. Therefore, cereals are classified mainly as energy-giving foods, not as medicines or primary sources of vitamin C.

Correct answer: A. Protein

Explanation: Pulses and milk are valuable sources of protein. Protein supplies amino acids needed for growth, formation and repair of body tissues, production of enzymes and hormones, and maintenance of muscles. Milk also contributes calcium and other nutrients, while pulses additionally provide fibre and several minerals.

Correct answer: A. Maintaining fluid balance in the body

Explanation: Maintaining fluid balance is a principal function of water. Water forms part of blood and cellular fluids, supports transport of nutrients and hormones, assists digestion, regulates body temperature, and helps remove wastes through urine and other routes. It provides neither protein nor fat and supplies no energy.

Correct answer: C. To improve diet adherence

Explanation: Considering a patient’s preferences allows the dietitian to select safe, acceptable foods within the prescribed restrictions. When meals suit taste, culture, routine, and availability, the patient is more likely to eat them consistently. Better acceptance improves adherence and helps the therapeutic diet achieve its intended health outcome.

Correct answer: A. Patient comfort and safety

Explanation: Food temperature must be appropriate for the patient’s comfort, tolerance, and safety. Food that is excessively hot can burn the mouth or throat, while food that is too cold may be uncomfortable or unsuitable for some conditions. Colour, quantity, and cost may matter in other contexts, but they are not the primary temperature checks.

Correct answer: B. A low-sodium or diabetic diet

Explanation: Food labels provide information about sodium, sugars, total carbohydrate, fat, serving size, and ingredients. This information is especially useful when selecting packaged foods for a low-sodium diet or a diabetes diet. Labels help identify hidden salt and added sugar, although they should be interpreted with the patient’s complete dietary plan.

Correct answer: B. Steaming

Explanation: Steaming is a cooking-method modification that can prepare food with little or no added oil. It may help reduce fat intake and preserve the natural flavour and some nutrients of food. The exact method depends on the patient’s condition; frying in excess oil generally increases energy and fat content rather than improving a low-fat therapeutic diet.

Correct answer: A. For safe swallowing

Explanation: A pureed diet changes the texture of food into a smooth, uniform consistency. This can make swallowing easier and reduce the risk of hard pieces, lumps, or poorly chewed food entering the airway. It may be prescribed for people with chewing or swallowing difficulty, but the texture and thickness should follow professional guidance.

Correct answer: C. Helping blood glucose control

Explanation: Regular meal timing helps distribute carbohydrate intake more evenly during the day. This can reduce large fluctuations in blood glucose and coordinate meals with medicines, insulin, activity, and the patient’s daily routine. The exact schedule must be individualized, but skipping meals or eating unpredictably can make glucose management more difficult.

Correct answer: D. Lemon and mild herbs

Explanation: Lemon juice and suitable mild herbs can add flavour without substantially increasing sodium. Other useful choices may include spices, garlic, ginger, or vinegar when appropriate. Doubling salt, salty pickles, and large amounts of packaged sauces defeat the purpose of a low-sodium diet because they may contain considerable sodium.

Correct answer: A. Excess saturated fat

Explanation: A fat-modified diet commonly limits excessive saturated fat and avoids frequent fried foods, depending on the medical purpose. High saturated-fat intake may adversely affect blood lipid levels and cardiovascular risk in susceptible people. The diet should still provide essential fats in suitable amounts; it does not mean eliminating every source of fat.

Correct answer: B. Fibre is increased or decreased

Explanation: A fibre-modified diet changes the amount or type of dietary fibre according to the patient’s condition. Fibre may be increased to support bowel regularity or reduced temporarily when intestinal irritation or obstruction risk requires it. The change should be gradual and accompanied by suitable fluid intake unless medically restricted.

Correct answer: C. Salt control

Explanation: Sodium-modified diets control the amount of sodium, often by limiting added salt and high-sodium foods such as salty snacks, pickles, processed foods, and some sauces. Such modification may be advised for selected conditions, but the required restriction varies. Reading labels and choosing fresh foods can help reduce sodium intake.

Correct answer: A. It can increase fat and energy intake

Explanation: Fried foods can absorb considerable oil during cooking, increasing their fat and energy density. Frequent excess intake may contribute to unwanted weight gain and may worsen some cardiovascular or metabolic risks. Frying does not automatically increase fibre, replace water, or create vitamin C, so moderation and varied cooking methods are preferred.

Correct answer: B. To make a practical and followable diet

Explanation: A diet plan must be affordable and realistic for the patient and family. Considering economic resources helps the dietitian choose nutritious local foods, suitable substitutes, and preparation methods that can be continued over time. An expensive plan may not be followed, whereas an affordable plan improves adherence without sacrificing nutritional adequacy.

Correct answer: A. They may be available and acceptable

Explanation: Local foods are often easier to obtain, less expensive, culturally familiar, and more acceptable to the patient. Using suitable local choices can make a therapeutic diet practical and sustainable while still meeting nutrient and medical restrictions. They do not automatically cure disease or replace prescribed medicines, and their suitability must be assessed individually.
