Significance

Sugar-sweetened drinks can supply substantial added sugar and energy while contributing little protein, fibre, or micronutrient value. Limiting them supports reduced added-sugar intake, better energy balance, dental health, and healthier beverage choices such as water or unsweetened options. It does not mean replacing drinks with medicines or focusing only on protein. Therefore, option B is correct.

Nutritional value does not make food automatically safe. Food can become contaminated with bacteria, viruses, parasites, chemicals, or toxins during preparation, storage, or serving. A patient may be especially vulnerable to foodborne illness, so hand hygiene, clean equipment, safe temperatures, separation of raw and cooked foods, and proper storage are essential. Therefore, option C is correct.

Proper nutrition supports immunity because proteins, vitamins, minerals, essential fats, and adequate energy are needed to build immune cells, maintain protective tissues, and produce effective immune responses. Nutritional deficiency can weaken resistance to infection and slow recovery. Therefore, the correct answer is that nutrition supports the body’s defence system, not any decorative or clothing-related activity.

Regular meal timing establishes a predictable routine, supports consistent energy intake, and may help digestion and appetite. It also makes it easier for a patient to follow prescribed portions, snacks, fluids, and medicines when timing matters. The schedule should still be adjusted for symptoms and the individual treatment plan.

Diet advice after discharge is an important part of continuity of care. It explains what foods, portions, meal timings, preparation methods and restrictions should be followed at home. Following the advice can maintain treatment benefits, prevent complications and support recovery. It does not mean that the patient should stop eating.

Food should be served at a temperature that is safe and comfortable for the individual patient. Very hot food may burn the mouth or throat, while very cold food may cause discomfort or be unsuitable for certain conditions. Temperature may need adjustment for sensitivity, swallowing problems, or medical instructions, so A is the best answer.

Large amounts of added sugar can raise blood glucose rapidly and provide energy without supplying many essential nutrients. Limitation may be important for diabetes, poor glucose control, dental problems, obesity, or a therapeutic plan. The restriction is not identical for every patient, so it should follow professional advice. Therefore, B is the correct reason.

Fried foods commonly absorb oil or fat during cooking. Eating them frequently or in large portions can therefore increase total fat and energy intake, especially when the oil is reused or the food is heavily coated. Excess energy may contribute to weight gain, while a high-fat pattern may increase long-term health risks. Fibre does not automatically increase because food is fried.

Fat is energy-dense, providing about nine kilocalories per gram, more than carbohydrate or protein. Therefore, adding large amounts of fatty foods can substantially increase total energy intake, especially when activity is low. Unsaturated fats are useful in suitable amounts, but all fats should be consumed with portion control.

Refined sugar supplies calories mainly as simple carbohydrate but contributes very little protein, fibre, vitamins or minerals. Excess intake can therefore provide ‘empty calories’, displace more nutritious foods and contribute to dental caries and excess energy intake. It does not increase calcium or fibre, so option A is correct.

A semi-liquid diet has a thicker, smoother consistency and may include foods such as porridge, custard, or thin cereal preparations that can often be eaten with a spoon. A full-liquid diet is more fluid and contains foods that become liquid at room temperature. The prescribed texture depends on swallowing and digestive ability.

A high-energy diet may be useful when a person is underweight, has increased energy requirements, is recovering from illness, or cannot eat large quantities. Energy-dense foods provide more calories in a smaller volume. Such a plan should still be balanced and individually prescribed; it is not designed primarily to reduce sodium or alter colour.

Clinical nutrition is growing because lifestyle-related conditions, chronic diseases, ageing, complex medical treatments, and public awareness have increased the need for specialised nutrition care. Dietitians help assess patients, plan therapeutic diets, support recovery, and prevent complications. The other options deny the established relationship between diet and health.
