Balanced diet and Recommended Dietary Allowances

Correct answer: D. Changing cooking method and increasing whole grains, fruits and vegetables

A diet dominated by fried foods may provide excess fat and energy while supplying too little fibre and protective nutrients. Replacing deep-frying with methods such as steaming, boiling, baking or shallow cooking can improve fat quality and reduce unnecessary oil. Increasing whole grains, fruits, vegetables and other fibre-rich foods supports bowel function and improves vitamin, mineral and phytochemical intake. Hence, option D is the appropriate improvement.

Correct answer: C. Adding a vitamin C-rich food to a plant source of iron

Plant foods commonly provide non-haem iron, whose absorption can be limited by other dietary factors. Vitamin C converts iron into a form that is more readily absorbed and can improve the utilisation of non-haem iron. Therefore, meals such as lentils with lemon, beans with tomatoes, or leafy vegetables with amla can be helpful. This principle supports dietary anaemia prevention, although diagnosis and treatment require professional assessment.

Correct answer: A. Vitamin D supports intestinal calcium absorption and its use in bone mineralisation

Vitamin D is essential for maintaining calcium balance because it increases the intestinal absorption of calcium and helps the body use calcium for bone mineralisation. Consequently, a person may consume adequate calcium yet have poor utilisation when vitamin D is deficient. Vitamin D does not add calcium to food and does not completely stop excretion. Bone health therefore depends on adequate calcium, vitamin D, physical activity and other factors.

Correct answer: A. To reduce iodine loss

Iodised salt is used to supply iodine, a micronutrient needed for thyroid hormone production and normal growth and development. Prolonged exposure to heat, moisture and cooking conditions can reduce the amount of iodine retained in food. Adding iodised salt near the end of cooking and storing it in a covered, dry container helps conserve iodine. Heating does not meaningfully convert salt into fibre or protein and does not remove its sodium in the intended way.

Correct answer: B. Improve fluid intake appropriately

Fibre absorbs water and adds bulk to stool, but increasing fibre without adequate fluid may worsen bloating, discomfort or constipation in some people. Fluid intake should therefore be assessed and improved appropriately before or along with a gradual increase in fibre, unless a medical condition requires fluid restriction. Regular activity, fruits, vegetables, whole grains and a planned routine can also support bowel function. Persistent or severe constipation needs medical evaluation.

Correct answer: A. To support the needs of the mother and developing foetus

Pregnancy involves growth of the foetus, formation of new tissues, expansion of maternal blood volume and preparation of the mother for childbirth and lactation. Adequate energy, protein, iron, folate, calcium and other nutrients support these processes and help protect maternal health. Therefore, option A is correct.

Correct answer: A. Protein may be used for energy

When the diet does not provide enough energy from carbohydrates and fats, the body can break down protein and use its amino acids as fuel. Consequently, less protein remains available for synthesis and repair of muscles, enzymes, hormones and other tissues. This is why adequate energy and protein must be planned together.

Correct answer: B. Because dietary fat helps the absorption of vitamins A, D, E and K

Vitamins A, D, E and K are fat-soluble. Dietary fat supports the formation of micelles and helps these vitamins pass from the intestine into the body. Thus, an extremely low-fat diet may reduce their absorption, while excessive fat is also undesirable. Balanced intake is the correct principle.

Correct answer: D. Principle of improving absorption

Plant foods mainly provide non-haem iron, whose absorption is generally lower than that of haem iron. Vitamin C helps convert iron into a more absorbable form and can reduce the effect of some inhibitors. Therefore, combining foods such as pulses or leafy vegetables with amla, guava, citrus fruit or tomatoes can improve iron absorption.

Correct answer: B. Because vitamin D helps intestinal calcium absorption and its use in the body

Vitamin D regulates calcium homeostasis and promotes active calcium absorption in the intestine. It also supports the proper use of calcium in bone mineralisation. Consequently, calcium planning should consider vitamin D status, sunlight exposure and, when appropriate, professional advice; simply increasing calcium may not solve poor absorption caused by deficiency.

Correct answer: B. To understand nutrient amounts and choose healthier, safer foods

Food labels provide information that helps consumers compare products and control their intake of sodium, added sugar, and fat. Excess sodium may contribute to high blood pressure in susceptible people, while excessive sugar and energy-dense fat can make weight and blood-glucose control more difficult. The serving size must be checked because the stated nutrient amount may apply to only one portion. Labels support informed choices but do not replace medical advice.

Correct answer: C. It may be energy-dense but nutrient-poor

Oil and sugar can provide considerable energy, but they do not by themselves supply adequate protein, dietary fibre, vitamins, or minerals. A food pattern with high energy and low protective nutrients may be described as energy-dense but nutrient-poor. It can contribute to excess energy intake without meeting the body’s needs for growth, repair, satiety, and digestive health. Therefore, the food should be assessed within the whole diet rather than called balanced.

Correct answer: C. To support the nutritional needs of the mother and developing fetus

Pregnancy involves growth and development of the fetus, formation of the placenta, expansion of maternal tissues and blood volume, and preparation for childbirth and breastfeeding. These processes increase the importance of adequate energy, high-quality protein, iron, folate, iodine, calcium, vitamin D, and other nutrients. Requirements should be met through a balanced, safe, and appropriately planned diet rather than indiscriminate overeating or removal of food groups.

Correct answer: C. Encouraging slower eating and measured portions

Eating speed can affect awareness of fullness and may encourage overeating before the body's satiety signals are noticed. Advising the patient to eat slowly, take small bites, chew well, pause during the meal and use measured portions can improve mindful eating and portion control. The aim is behaviour change, not unnecessary food restriction.

Correct answer: C. It is an energy-dense but nutrient-poor diet

Energy density describes how many calories a food provides in a given amount; it does not indicate that the food supplies sufficient fibre, vitamins, minerals, or protective compounds. A diet based on refined, fatty, or sugary foods may provide many calories while remaining nutrient-poor. Such a pattern can contribute to excess energy intake and micronutrient inadequacy, so variety and nutrient density should be improved.

Correct answer: B. Because vitamin D supports intestinal calcium absorption and its use in bone mineralisation

Vitamin D increases the efficiency of intestinal calcium absorption and helps maintain calcium balance needed for bone mineralisation. Therefore, planning calcium intake without considering vitamin D status may give an incomplete picture of bone nutrition. Adequate vitamin D does not eliminate the need for calcium, but it supports the body’s ability to absorb and use calcium. The other options describe unrelated effects.

Correct answer: C. It may be energy-dense but nutrient-poor

Oil and sugar provide considerable energy, but they do not supply the full range of nutrients needed for a balanced diet. A food with much energy and little protein, fibre, vitamins, or minerals may be described as energy-dense but nutrient-poor. Frequent reliance on such foods can reduce diet quality and may increase risks associated with excess energy intake. The conclusion does not mean that all oil or sugar must be eliminated; amounts and the total dietary pattern matter.

Correct answer: A. Include vegetables in a varied balanced diet to obtain fibre and other nutrients

Vitamin supplements may help correct a diagnosed deficiency, but they do not fully replace the fibre, water, variety of vitamins and minerals, and beneficial plant compounds supplied by vegetables. The patient should therefore include suitable vegetables in a varied balanced diet, while using supplements only as advised by a qualified professional. Increasing the dose without advice may be ineffective or harmful, and supplements cannot correct every problem caused by a poor dietary pattern. Food-based improvement remains the central goal unless a clinical condition requires a specific modification.

Correct answer: B. Offer nutrient-rich foods frequently in small portions

When large meals cause discomfort, dividing the daily intake into smaller, more frequent meals may improve tolerance and make it easier to meet energy and protein needs. Each portion should be nutrient-dense and selected according to the patient’s medical condition, swallowing ability, digestion, preferences, and prescribed restrictions. Forcing large portions can worsen symptoms, while stopping food or removing whole food groups may increase nutritional inadequacy. The plan should be monitored and adjusted by the healthcare team if symptoms persist.

Correct answer: B. Using suitable spices and a small amount of lemon in moderation for flavour

Excess sodium can be harmful, particularly for people who need sodium restriction because of hypertension, fluid retention, or certain heart and kidney conditions. Herbs, suitable spices, garlic, and a small amount of lemon can improve flavour without adding much sodium. Thus, option B is the safest choice among the alternatives.

Correct answer: B. It may be energy-dense but nutrient-poor

Oil and sugar provide considerable energy, but they contribute little protein, fibre, vitamins and minerals. A food pattern with excessive energy and inadequate protective nutrients may be described as energy-dense but nutrient-poor. Regularly relying on such foods can increase the risk of poor diet quality, excessive weight gain and nutrient inadequacy. A balanced diet should supply appropriate amounts of all major nutrients.

Correct answer: C. Local seasonal fruits or other affordable protective foods

A sound nutrition plan must consider affordability, availability, culture, and seasonal supply. Local seasonal fruits can provide vitamins, minerals, fibre, and protective phytochemicals at a lower cost than imported fruits. If fruit is still unavailable, suitable affordable protective foods such as selected vegetables, sprouts, or other locally accessible choices may be included without removing the whole food group.

Correct answer: A. Calcium and vitamin D

Calcium provides the mineral structure of bone, while vitamin D helps the intestine absorb calcium and supports bone mineralisation and muscle function. Adequate protein, safe weight-bearing activity, and appropriate sunlight exposure may also contribute to bone health. Sugar, oil, or chilli alone cannot prevent osteoporosis, so the best answer among the options is A.

Correct answer: D. Limit very spicy condiments

Very spicy, irritating, or greasy foods may worsen symptoms in some patients with gastric irritation, although tolerance differs and diet does not replace medical treatment. Limiting foods that clearly trigger pain, burning, reflux, or discomfort is sensible, while choosing balanced, adequately nourishing meals. The patient should follow the diagnosed condition’s treatment and seek advice for persistent or severe symptoms.

Correct answer: C. Identify a specific nutrition problem

A nutrition diagnosis identifies and clearly describes a specific nutrition problem that can be addressed through nutrition intervention. It is based on assessment findings and helps connect the patient’s intake, clinical signs, behaviour, or other evidence with an appropriate plan. It is different from a medical disease diagnosis and supports targeted intervention and monitoring.
