Balanced diet and Recommended Dietary Allowances

Correct answer: C. क्योंकि उसमें आवश्यक पोषक तत्वों की कमी हो सकती है

Satiety or fullness does not necessarily mean that the body has received adequate nutrition. A food may provide bulk or calories but lack protein, vitamins, minerals, essential fatty acids, fibre, or other nutrients. A balanced diet must provide sufficient variety and nutrient quality, not merely fill the stomach. Therefore, the possible lack of essential nutrients makes option C correct.

Correct answer: C. Deficiency of micronutrients

Hidden hunger is a form of malnutrition in which a person may consume enough calories or may not appear visibly underweight, yet lacks essential micronutrients such as iron, iodine, vitamin A, zinc, or folate. It can impair immunity, growth, learning, and work capacity. Because the deficiency is not always obvious from hunger or body size alone, it is called hidden hunger. Therefore, option C is correct.

Correct answer: B. Body building and tissue repair may be affected

Energy and protein are separate nutritional requirements. A person may receive enough calories from carbohydrates or fat but still lack sufficient protein for growth, maintenance of muscles, production of enzymes and hormones, and repair of body tissues. Prolonged protein deficiency can contribute to poor growth, loss of muscle, delayed healing, and reduced immunity. Hence, option B is correct.

Correct answer: A. Energy intake being greater than the body’s requirement

Overnutrition occurs when intake of energy or particular nutrients is consistently greater than the body’s needs. Excess calories, especially from energy-dense foods and drinks high in added sugar or fat, can lead to weight gain and increase the risk of obesity, diabetes, cardiovascular disease, and other conditions. Energy balance also depends on activity and metabolism, but excessive energy intake is a major dietary cause. Therefore, option A is correct.

Correct answer: B. Because fat can help their absorption

Vitamins A, D, E, and K are fat-soluble vitamins. Dietary fat helps stimulate bile release and supports the formation of micelles, which assist these vitamins in being absorbed through the intestine. This does not mean that very large amounts of fat are required; a suitable amount is generally sufficient, and the type of fat also matters for health. Therefore, option B is correct.

Correct answer: A. It can support the absorption and use of some iron

Vitamin C improves the absorption of non-haem iron, the form commonly found in plant foods such as pulses, cereals, and leafy vegetables. It helps convert iron into a form that the intestine can absorb more readily. This is why lemon, amla, guava, or other vitamin C-rich foods may be eaten with iron-containing meals. It does not remove iron, add salt, or destroy calcium.

Correct answer: C. To help reduce iodine loss

Iodine in iodized salt can be lost to some extent through prolonged heating, moisture, and improper storage. Adding the salt toward the end of cooking may help reduce exposure to heat and conserve more iodine in the prepared food. It does not whiten the food, double the amount of salt, or primarily preserve the meal. Iodized salt should also be stored in a covered, dry container.

Correct answer: A. They may contain high amounts of hidden salt, sugar, or fat

Many highly processed foods can contain substantial amounts of added sugar, sodium, saturated fat, or energy while providing relatively little fibre and micronutrient value. Frequent intake may therefore make it harder to maintain a balanced diet, especially when these foods replace fruits, vegetables, pulses, and whole grains. Not every processed food is unhealthy, so labels, ingredients, portion size, and the degree of processing should be considered.

Correct answer: A. Adequacy of fibre and water

Constipation is often associated with hard or infrequent stools, and insufficient fibre or fluid intake may contribute to it. Suitable dietary fibre adds bulk to stool, while adequate fluid helps the fibre work and supports softer stool consistency. The patient’s medical condition, swallowing ability, activity level and healthcare advice must also be considered; a sudden large fibre increase may not suit everyone. Therefore, option A is the appropriate general dietary consideration.

Correct answer: A. Vitamins, minerals, and fibre may be low

Adequate food quantity does not necessarily mean adequate diet quality. Fruits and vegetables commonly contribute vitamins, minerals, dietary fibre, and protective phytochemicals. If they are eaten in insufficient amounts, the patient may have a less varied diet and a higher risk of inadequate micronutrient and fibre intake, even when total calories appear sufficient. Nutrition assessment must therefore consider both quantity and composition.

Correct answer: C. By slowing tissue repair

Protein supplies amino acids needed to build and repair muscles, skin, blood components, and other body tissues. During illness, injury, or surgery, inadequate protein can reduce tissue formation, weaken immunity, and delay wound healing and recovery. Thus, option C correctly describes the main effect of protein deficiency.

Correct answer: A. When more fibre and better nutrient quality are needed

Whole grains retain the bran and germ in addition to the endosperm, so they generally provide more dietary fibre and several vitamins, minerals, and beneficial plant compounds than refined grains. Fibre can support bowel health and satiety. Thus, when improved fibre and nutrient quality are desired, option A is correct.

Correct answer: A. High in energy and low in protective nutrients

Oil is energy-dense, so using too much can raise the calorie content of a meal without supplying many vitamins, minerals, or dietary fibre. Vegetables provide protective nutrients such as vitamin C, folate, carotenoids, minerals, and fibre; eating few vegetables reduces these contributions. Thus, the overall diet may become energy-rich but poor in protective nutrients. Option A is the only accurate answer.

Correct answer: A. Suggesting healthy drinks with less sugar

Very sweet drinks often provide large amounts of added sugar and calories but relatively little protein, fibre, vitamins, or minerals. Replacing them with water, unsweetened lemon water, plain milk when suitable, or unsweetened buttermilk can reduce excess sugar while maintaining hydration and, in some cases, nutrient intake. The exact choice must consider the patient’s condition. Fluids should not be stopped, and fried foods are not a healthy replacement.

Correct answer: A. Total daily energy and nutrient intake may reduce

Breakfast can contribute energy, protein, fibre, vitamins, minerals, and regular meal structure. Skipping it may reduce the total amount and variety of food eaten during the day, especially when the missed meal is not replaced with nutritious foods. Some people may later overeat energy-dense snacks, while others may fail to meet nutrient requirements. The effect is not identical for everyone, but reduced overall energy and nutrient intake is a valid possible consequence. Therefore, option A is correct.

Correct answer: A. Choosing affordable nutrient sources like pulses and seasonal vegetables

Choosing affordable, locally available foods such as pulses, cereals, seasonal vegetables, fruits, milk or curd can provide protein, vitamins, minerals and fibre at a reasonable cost. Seasonal and minimally processed foods are often cheaper than supplements or highly packaged products. A balanced diet does not require expensive foods; it requires variety, suitable portions and wise planning. Therefore, option A is correct.

Correct answer: A. Energy fuels the body and fibre helps digestion

Energy-yielding nutrients, mainly carbohydrates and fats and also protein, provide fuel for metabolism, movement, growth and repair. Dietary fibre is not a digestive enzyme and generally does not supply usable energy in the usual school-level classification. It adds bulk, supports bowel movement, helps prevent constipation and may improve blood-glucose and cholesterol control. Thus, option A correctly states their complementary roles.

Correct answer: A. Checking food groups, quantity, quality and hygiene

Evaluating a balanced diet requires a comprehensive approach. The assessment should consider representation of major food groups, adequacy of portions, nutrient quality, variety, meal frequency, safety and hygiene. Colour, taste or plate size alone cannot show whether the diet supplies enough energy and essential nutrients. Therefore, option A is the most complete and academically correct approach.

Correct answer: A. They may contain hidden salt, sugar, or unhealthy fat and may provide little fibre

Many processed foods are formulated with substantial sodium, added sugar, saturated fat, or refined starch, while offering relatively little fibre and fewer protective nutrients than minimally processed alternatives. Frequent intake can make it harder to control blood pressure, blood glucose, body weight, and overall diet quality. Processing itself is not always harmful, so the label, ingredients, serving size, and total dietary pattern should be considered.

Correct answer: A. Matching food quantity with nutrition needs

Portion control means adjusting the amount of food served and eaten according to a person’s energy and nutrient needs. It helps prevent both excessive intake and inadequate intake, supports a balanced diet, and makes dietary advice more practical. Therefore, option A is correct; the other options are unrelated to nutrition planning.

Correct answer: A. Because energy needs and expenditure may change.

Physical activity changes how much energy the body spends. A more active patient may need additional energy and sometimes more carbohydrate, while reduced activity may require adjustment to prevent unwanted weight gain. The final plan also considers illness, age, body size, and treatment; activity is one important factor affecting energy balance and recommended intake.

Correct answer: D. Increasing the balance among food groups

Cereals are important sources of energy, but a cereal-heavy plate may not provide enough protein, calcium, vitamins, minerals and fibre. Adding suitable amounts of pulses, milk or alternatives, fruits and vegetables improves variety and nutrient balance. The goal is not to remove cereals, but to include all appropriate food groups in suitable proportions.

Correct answer: A. तरल सेवन सुधारना

Dietary fibre adds bulk and can support bowel movement, but fibre works best when adequate fluid is available. If fibre is increased while fluid intake remains very low, constipation, bloating, or discomfort may worsen in some people. Fluid needs depend on medical conditions, so a patient should follow professional advice, especially if there is fluid restriction. Therefore, option A is correct.

Correct answer: D. Because it may provide excess energy while supplying fewer essential nutrients

Oil and sugar are energy-dense ingredients, but foods containing large amounts of them may provide relatively little protein, fibre, vitamins, and minerals. If such foods displace pulses, vegetables, fruits, whole grains, or other nutrient-rich foods, the diet can become high in calories but poor in essential nutrients. This is why option D accurately describes reduced nutrient quality.

Correct answer: B. Add a variety of fruits and vegetables for vitamins, minerals, and fibre

Fruits and vegetables provide vitamins, minerals, dietary fibre, water, and many protective plant compounds. Variety improves the chance of receiving different micronutrients and colours of produce, while fibre supports digestive health. They should complement rather than unnecessarily replace all cereals or other food groups. Increasing fried foods or stopping water would not correct the nutritional gap, so option B is best.
