Balanced diet and Recommended Dietary Allowances

Correct answer: A. They may reduce variety and nutrient intake

A balanced diet requires adequacy, variety and moderation. Unnecessary or excessive restrictions can remove whole food groups and reduce energy, protein, vitamins, minerals or fibre. Restrictions may be medically necessary in particular conditions, but they should be individualized rather than extreme. Hence option A is correct.

Correct answer: A. It may cause digestive discomfort

A very large meal close to bedtime may cause fullness, reflux, bloating or other digestive discomfort, especially when it contains much fat and is eaten quickly. Meal timing and quantity should suit the person’s routine and health; a late dinner is not automatically harmful, but the described heavy pattern is undesirable. Thus option A is correct.

Correct answer: A. Availability of some nutrients may increase

During sprouting, biochemical changes can improve the digestibility of some pulses and may increase the availability of certain vitamins and minerals. Sprouting does not make every nutrient increase and safe hygiene is essential because moist sprouts can support bacterial growth. In the context of the question, option A is correct.

Correct answer: A. Some water-soluble nutrients may reduce

When cut vegetables remain in water for a long time, water-soluble vitamins and some minerals can diffuse from the cut surfaces into the water. This reduces their nutritional value, particularly when the soaking water is discarded. Vegetables should be washed before cutting or washed briefly and cooked promptly; hence option A is correct.

Correct answer: A. Not taking any food beyond need

Moderation means consuming foods in suitable amounts according to the body’s needs, activity, age and health, without excessive intake. It does not mean fasting, eliminating all favourite foods or eating only one item. Moderation works together with variety and adequacy to form a balanced diet; therefore, option A is correct.

Correct answer: A. To keep fat and energy intake balanced

Oils are concentrated sources of energy, and excessive use can raise total fat and calorie intake beyond the body’s needs. Using a suitable amount helps maintain energy balance while still supplying essential fatty acids and allowing food to remain palatable. Oil control does not mean eliminating all fat; therefore, option A is correct.

Correct answer: A. Pulses and gram

Pulses and gram are legumes that provide substantial plant protein and can be combined with cereals to improve the overall amino-acid pattern of a meal. Groundnuts and sesame also contain protein but are especially rich in fat; salt, sugar, oil and ghee do not provide meaningful protein. Therefore, option A is the best answer.

Correct answer: A. They may contain more salt, sugar or fat

Many highly processed foods are formulated with substantial added salt, sugar or saturated fat and may contain less fibre and fewer naturally occurring nutrients than minimally processed foods. Frequent excess intake can increase total energy and sodium consumption. Some processed foods can fit a healthy diet, so the label and portion matter; option A is correct.

Correct answer: A. Following variety, balance and moderation

Healthy eating is based on variety, balance and moderation. Variety supplies different nutrients, balance provides appropriate proportions of food groups, and moderation prevents excessive sugar, salt, fat or total energy intake. Together, these principles support growth, health and disease prevention.

Correct answer: C. To supply different nutrients

Different food groups contain different combinations of carbohydrates, proteins, fats, vitamins, minerals, fibre and water. Including cereals, pulses, milk or alternatives, fruits, vegetables and suitable fats helps meet the body's varied requirements. Thus, food-group inclusion provides nutritional adequacy and balance.

Correct answer: D. When fluid balance, digestion and temperature control are concerned

Water is an essential component of the diet and is needed for transporting nutrients, removing wastes, supporting digestion, maintaining blood volume and regulating body temperature. Its importance is not limited to relieving thirst. Thus, fluid balance, digestion and temperature control clearly demonstrate why water must be considered in nutrition.

Correct answer: B. It is a guide for nutrient needs of healthy people

A recommended dietary allowance, or RDA, is a reference value intended to guide the daily intake of a nutrient for healthy people in a particular age, sex or physiological group. It supports meal planning and assessment, but it is not a medicine or an exact prescription for every individual. Illness and special needs may require professional adjustment.

Correct answer: A. Because heat and excess water can reduce heat-sensitive and water-soluble vitamins

Overcooking exposes food to heat for a longer period and often uses a large amount of water. Heat-sensitive vitamins, especially vitamin C and some B vitamins, may be destroyed, while water-soluble vitamins can move into the cooking water and be discarded. Using less water and cooking for only the necessary time helps conserve nutrients.

Correct answer: A. When food provides energy along with protein, vitamins, minerals, and fibre

Option A is correct because a balanced diet supplies energy-giving nutrients as well as body-building and protective nutrients in suitable proportions. Protein supports growth and tissue repair, vitamins and minerals regulate important body processes, and fibre supports digestion. Simply feeling full may result from eating large amounts of rice or sweets, but such food choices may not provide all essential nutrients. Therefore, fullness alone is not proof of a balanced diet.

Correct answer: C. When a person can take varied sources like pulses, milk, eggs, or nuts

Protein variety improves the chances of obtaining adequate amounts of essential amino acids and other nutrients. Pulses, milk, eggs, and nuts contribute protein in different amounts and with different nutrient profiles. Combining varied sources can improve overall diet quality, especially when plant proteins are complemented appropriately. Sugar, salt, and meal skipping do not provide meaningful protein variety.

Correct answer: C. A balanced mix of energy-giving, protein-rich, and protective foods

A healthy breakfast should contribute to the day’s energy and nutrient requirements rather than consist only of sugar, fat, or a beverage. A balanced combination may include an energy-giving cereal or grain, a protein source such as milk, pulses, or eggs, and protective foods such as fruit or vegetables. Thus option C reflects variety, balance, and adequate nourishment.

Correct answer: C. Combining cereals, pulses, vegetables, fruits, milk, and suitable fats

A balanced diet contains foods from different groups in suitable amounts and proportions so that the body receives energy, protein, essential fats, vitamins, minerals, fibre, and water. Cereals and pulses can complement one another, while vegetables, fruits, milk, and suitable fats add further nutrients. Eating only a few foods, taking only sweets, or skipping meals cannot provide balanced nourishment. Hence option C is the best answer.

Correct answer: A. To provide different essential nutrients in adequate amounts

Different food groups contribute different nutrients. Cereals and millets provide energy, pulses and animal foods provide protein, milk may provide protein and calcium, while fruits and vegetables supply vitamins, minerals, fibre, and protective compounds. Variety therefore improves nutritional adequacy and helps form a balanced diet rather than one based on only energy-giving foods.

Correct answer: A. Getting all nutrients in proper amounts

Balance means that the diet supplies different essential nutrients in suitable proportions and amounts for the person’s age, sex, activity, and physiological condition. A balanced diet includes variety from appropriate food groups and avoids dependence on one food. It supports energy, growth, repair, regulation, and maintenance of health.

Correct answer: B. Different food groups

A balanced plate should contain suitable amounts of foods from different groups, such as cereals or other grains, pulses or protein foods, vegetables, fruits, and milk or alternatives. This variety supplies carbohydrates, protein, healthy fats, vitamins, minerals, fibre, and water. A plate containing only sweets, fried foods, or sugary drinks cannot meet the body’s needs and may increase the risk of unhealthy weight gain and nutrient deficiencies.

Correct answer: C. It retains dietary fibre

Whole fruit generally retains its natural dietary fibre, especially in the edible skin and pulp, whereas much of this fibre may be lost when fruit is strained or processed into juice. Fibre slows digestion, supports bowel regularity, increases fullness, and can help moderate the rise in blood glucose. Juice may also be consumed quickly and may provide concentrated natural or added sugar, so whole fruit is usually the more filling choice.

Correct answer: D. It helps regulate hunger and energy intake

Following reasonably regular meal timings can help a person recognise normal hunger and avoid very long gaps that may lead to overeating. It also supports a more organised distribution of energy and nutrients throughout the day. Meal timing alone does not guarantee health: the quality, quantity, hydration, physical activity, sleep, and individual medical needs of the person also matter.

Correct answer: A. They can provide healthy fats, protein, fibre, and other nutrients

Nuts and seeds can supply unsaturated fats, plant protein, dietary fibre, vitamin E, magnesium, and other beneficial nutrients. However, they are energy-dense, meaning a small portion contains considerable calories. Eating an appropriate portion can add nutritional quality to the diet, while frequent overeating may contribute excess energy. Plain or lightly processed varieties are generally preferable to heavily salted, sugared, or fried products.

Correct answer: A. Nutritional needs and food selection

Menu planning involves selecting meals that meet nutritional needs while considering age, health condition, food preferences, culture, budget, availability, variety, and preparation facilities. It aims to make meals balanced, acceptable, safe, and practical. Wall colour, vehicle repair, and musical tune do not determine nutritional suitability. Hence, option A is correct.

Correct answer: B. Guiding people about balanced diets and healthy food choices

A nutrition educator teaches individuals or groups how to choose balanced meals, understand food groups, read nutrition information and develop healthy eating habits. Surgery belongs to medical practice, while industrial manufacturing and architectural design are different occupations. Therefore, guidance about balanced diets and healthy choices in option B is correct.
