Nutrition, Health and Well-being — NCERT Solutions

Given: The dietary components — saturated fats, excess sugars and salt — and their effects on school-age children.

Reasons to limit each:

1. Saturated Fats:

• Saturated fats (found in butter, ghee, fried foods, processed foods) raise the level of LDL (bad) cholesterol in the blood.
• Excess consumption leads to deposition of fat in blood vessels (atherosclerosis), increasing the risk of heart disease and hypertension (high blood pressure) in later life.
• Excess fat intake also contributes to childhood obesity, which is increasingly common.
• Obese children are at higher risk of developing Type 2 diabetes, joint problems and psychological issues.

2. Excess Sugars:

• Foods high in sugar (sweets, chocolates, soft drinks, pastries) provide empty calories — energy without essential nutrients.
• Excess sugar intake leads to tooth decay (dental caries), as bacteria in the mouth feed on sugar and produce acids that erode tooth enamel.
• It contributes to obesity and increases the risk of Type 2 diabetes (deficiency of insulin leading to high blood glucose).
• High sugar intake can also cause energy spikes and crashes, affecting the child's concentration and mood.

3. Excess Salt (Sodium):

• High salt intake is associated with hypertension (high blood pressure).
• Habits formed in childhood tend to persist into adulthood, so a high-salt diet in childhood increases the risk of cardiovascular diseases in adult life.
• Excess sodium also affects kidney function.

Conclusion: Limiting saturated fats, excess sugars and salt in a school child's diet helps prevent obesity, dental problems, hypertension and diabetes, and promotes long-term health and well-being.

Given: The practice of involving school-age children in meal planning.

Ways in which involving children in meal planning promotes healthy eating:

1. Develops ownership and interest: When children are involved in choosing and planning meals, they feel a sense of ownership and are more likely to eat what they have helped plan.

2. Increases awareness: Children learn about different foods, their nutritional value and the importance of a balanced diet. This knowledge helps them make healthier food choices.

3. Reduces fussiness: Children who are involved in meal planning are less likely to be fussy eaters, as they have had a say in what is being prepared.

4. Teaches life skills: Participating in meal planning and preparation teaches children practical life skills such as budgeting, cooking and food hygiene.

5. Encourages variety: Children can be guided to include a variety of foods from different food groups, making meals more nutritious.

6. Builds healthy habits: Positive experiences with food planning and preparation during childhood are likely to result in healthy eating habits that continue into adulthood.

Conclusion: Involving children in meal planning is an effective strategy to encourage healthy eating, develop nutritional awareness and build lifelong healthy food habits.

Given: The statement that childhood obesity is increasing.

Definition: Obesity is a condition in which excess body fat has accumulated to the extent that it may have a negative effect on health.

Reasons for the increase in childhood obesity:

1. Unhealthy dietary habits:

• Increased consumption of high-calorie, high-fat, high-sugar processed and fast foods (chips, burgers, pizzas, soft drinks, chocolates).
• These foods are energy-dense but nutrient-poor, leading to excess calorie intake.

2. Sedentary lifestyle:

• Children today spend more time watching television, playing video games and using smartphones/computers.
• Physical activity has reduced significantly, so fewer calories are burned.

3. Reduced outdoor play:

• Urbanisation, lack of safe play spaces and increased academic pressure have reduced the time children spend in outdoor physical activities.

4. Influence of media and advertising:

• Aggressive advertising of junk food and fast food on television and social media influences children to demand and consume these unhealthy foods.

5. Peer influence:

• Children tend to eat what their peers eat. If peers consume junk food, the child is likely to follow.

6. Skipping breakfast:

• Children who skip breakfast tend to overeat later in the day, often choosing unhealthy snacks.

7. Genetic factors:

• Children with obese parents are at a higher risk of becoming obese due to genetic predisposition.

8. Emotional eating:

• Stress, anxiety and boredom can lead children to eat for comfort rather than hunger.

Consequences: Childhood obesity increases the risk of Type 2 diabetes, hypertension, heart disease, joint problems and psychological issues like low self-esteem.

Conclusion: A combination of poor diet, physical inactivity and environmental factors is responsible for the rising trend of childhood obesity.

Given: The Mid-day Meal Scheme and its impact on children's health and school performance.

About the Mid-day Meal Scheme:
The Mid-day Meal Scheme is a Government of India programme that provides free cooked meals to children in government and government-aided primary schools. It is one of the largest school feeding programmes in the world.

How it has boosted children's health:

1. Improved nutritional status: The meal provides a significant portion of the child's daily energy and protein requirements, helping to address malnutrition, especially among children from low-income families.

2. Reduction in anaemia: Inclusion of iron-rich foods in the meal helps reduce the prevalence of iron-deficiency anaemia among school children.

3. Improved immunity: A nutritious meal strengthens the immune system, making children less susceptible to infections and communicable diseases.

4. Better growth: Regular nutritious meals support healthy physical growth and development.

How it has boosted school performance:

1. Increased enrolment: The promise of a free meal has attracted more children, especially girls and children from disadvantaged communities, to enrol in school.

2. Reduced absenteeism: Children are more regular in attending school when they know they will receive a meal.

3. Improved concentration: A child who is well-fed can concentrate better in class, leading to improved learning outcomes.

4. Reduced hunger: Many children come to school hungry. The mid-day meal addresses this hunger, improving their ability to learn and participate in class activities.

5. Social benefits: Children from different castes and communities eat together, promoting social equality and integration.

Conclusion: The Mid-day Meal Scheme has been highly effective in simultaneously improving the nutritional status and educational performance of school-age children in India.

Given: A situation where village children are malnourished. The task is to advise parents on the following aspects.

(i) Role of adequate nutrition in protecting children from diseases:

I would explain to the parents:

• Adequate nutrition strengthens the immune system, which is the body's natural defence against infections and diseases.
• Well-nourished children have better resistance to communicable diseases like measles, diarrhoea, respiratory infections and tuberculosis.
• Specific nutrients play protective roles:
• Vitamin A protects the mucous membranes (first line of defence against germs) and supports immune cell function.
• Vitamin C enhances immunity and helps in wound healing.
• Iron and zinc are essential for the production and functioning of immune cells.
• Protein is needed to produce antibodies that fight infections.
• Malnourished children have weakened immunity, making them more vulnerable to infections. Even if they survive an infection, recovery is slower and complications are more likely.
• Adequate nutrition also ensures proper physical and mental development of the child.

(ii) Planning balanced meals for young children:

I would advise parents to:

• Include foods from all food groups in every meal:
• Cereals (rice, wheat, ragi, maize) — for energy
• Pulses (dal, beans, groundnuts) — for protein
• Milk and milk products (milk, curd) — for calcium and protein
• Fruits and vegetables (especially green leafy vegetables and yellow/orange fruits) — for vitamins and minerals
• Fats and oils (ghee, oil) — for energy and fat-soluble vitamins
• Use locally available and low-cost foods to prepare nutritious meals (e.g., ragi porridge, khichdi, dal-rice, seasonal vegetables).
• Feed young children small, frequent meals (5–6 times a day) as their stomach is small.
• Ensure food is clean and hygienically prepared to prevent food-borne illnesses.
• Avoid giving too many sweets, fried foods and junk foods.
• Encourage the child to eat a variety of foods to ensure all nutrients are obtained.

(iii) Communicable diseases and importance of immunisation:

I would explain:

• Communicable diseases are diseases that spread from one person to another through air, water, food, contact or insects. Examples: measles, polio, tuberculosis, diphtheria, whooping cough, tetanus.
• These diseases are especially dangerous for young, malnourished children and can cause death or permanent disability.
• Immunisation (vaccination) is the most effective and low-cost method of preventing communicable diseases.
• Vaccines work by introducing a weakened or killed form of the disease-causing organism into the body, which stimulates the immune system to produce antibodies. If the child is later exposed to the actual disease, the immune system recognises and fights it quickly.
• Immunisation not only protects the individual child but also contributes to herd immunity, protecting the entire community.
• Parents should ensure that all children receive their vaccines on time as per the immunisation schedule.

(iv) Immunisation schedule during preschool years:

I would share the following schedule with parents:

• I would stress that missing a vaccine dose leaves the child unprotected and that booster doses are as important as the first doses.
• Vaccines are available free of cost at government health centres and anganwadis.

Given: A two-month-old infant with repeated diarrhoea. The task is to explain nutritional needs, importance of exclusive breastfeeding and low-cost complementary foods.

Nutritional needs of infants:

• Infants (0–12 months) are in a period of rapid growth and development. Their nutritional needs per unit of body weight are higher than at any other stage of life.
• Energy: Infants need approximately 108 Kcal/kg body weight per day (0–6 months) to support rapid growth, brain development and physical activity.
• Protein: Essential for growth and development of all body tissues, including the brain. Breast milk provides the ideal quality and quantity of protein for infants.
• Fat: Provides energy and is essential for brain development. Breast milk contains the right proportion of fats, including essential fatty acids (DHA) needed for brain and eye development.
• Calcium and Phosphorus: Essential for bone and teeth development.
• Iron: Needed for haemoglobin formation and brain development. Breast milk iron, though present in small amounts, is highly bioavailable.
• Vitamins A, C and D: Essential for immunity, skin health, bone development and vision.
• Water: Infants have a high water requirement relative to body weight. Breast milk provides adequate water.

Importance of exclusive breastfeeding for the baby's health and development:

• Exclusive breastfeeding means giving the infant only breast milk (no water, other liquids or foods) for the first six months of life.
• Nutritional completeness: Breast milk is the perfect food for infants — it contains all nutrients in the right proportions needed for growth and development.
• Immunity: Breast milk contains antibodies (immunoglobulins), especially IgA, which protect the infant from infections. Colostrum (the first milk produced after birth) is especially rich in antibodies and is called the infant's first vaccine.
• Protection against diarrhoea: Breast milk contains anti-infective factors that protect the gut lining and prevent the growth of harmful bacteria. Exclusively breastfed infants have significantly lower rates of diarrhoea and respiratory infections.
• Easy digestion: Breast milk is easily digested by the infant's immature digestive system, reducing the risk of digestive problems.
• Brain development: Breast milk contains DHA (docosahexaenoic acid), an essential fatty acid crucial for brain and eye development.
• Emotional bonding: Breastfeeding promotes a strong emotional bond between mother and child, which is important for the child's psychological development.
• Economic advantage: Breast milk is free, always available at the right temperature and requires no preparation.
• For the mother: Breastfeeding helps the uterus return to its normal size, reduces the risk of breast and ovarian cancer and helps the mother lose pregnancy weight.

In the case of this two-month-old infant with repeated diarrhoea:

• The mother should be strongly advised to continue exclusive breastfeeding and not give any other food or water.
• Breastfeeding should be continued even during diarrhoea as it provides fluids, nutrients and antibodies that help the baby recover faster.
• ORS (Oral Rehydration Solution) should be given to prevent dehydration.
• The mother should consult a doctor if diarrhoea persists.

Low-cost complementary foods and their preparation from locally available foodstuffs:

(Note: Complementary foods are introduced after 6 months of age. For this two-month-old, only breast milk is recommended. However, the following information is provided for when the baby reaches 6 months.)

• Complementary foods are foods given in addition to breast milk after 6 months of age.
• They should be energy-dense, nutritious, locally available, low-cost, hygienic and of appropriate texture.

Examples of low-cost complementary foods and their preparation:

1. Rice/Wheat/Ragi Porridge:

• Preparation: Cook rice, wheat flour or ragi flour in water or milk to a soft, semi-liquid consistency. Add a little jaggery or sugar and a few drops of ghee to increase energy density.
• Nutrients provided: Energy (carbohydrates), calcium (ragi), iron (ragi).

2. Khichdi (Rice + Dal):

• Preparation: Cook rice and moong dal together with a little salt and ghee until very soft and mushy.
• Nutrients provided: Energy, protein, iron.

3. Mashed Banana or Papaya:

• Preparation: Mash ripe banana or papaya to a smooth consistency.
• Nutrients provided: Energy, Vitamin A (papaya), Vitamin C, potassium.

4. Dal Soup:

• Preparation: Cook moong or masoor dal until soft, strain and give the liquid as soup.
• Nutrients provided: Protein, iron, B vitamins.

5. Mashed Potato with Ghee:

• Preparation: Boil and mash potato, add a little ghee and salt.
• Nutrients provided: Energy, Vitamin C.

6. Egg Yolk:

• Preparation: Hard boil an egg, remove the yolk and mash it with a little water or breast milk.
• Nutrients provided: High-quality protein, iron, Vitamin A, Vitamin D.

Key principles for preparation:

• Always wash hands before preparing food.
• Use clean utensils and water.
• Food should be freshly prepared and not stored for long.
• Start with thin consistency and gradually thicken as the baby grows.
• Introduce one new food at a time to check for allergies.

Given: The task of developing healthy food habits in school-going children.

Steps involved in developing healthy food habits in school-going children:

1. Be a role model:

• Children learn by observing adults. Parents and teachers should themselves practise healthy eating habits.
• If adults eat fruits, vegetables and balanced meals, children are more likely to follow.

2. Involve children in meal planning and preparation:

• Allow children to participate in choosing healthy foods and helping in simple cooking tasks.
• This creates interest in food and makes them more willing to try new foods.

3. Offer a variety of nutritious foods:

• Introduce children to a wide variety of foods from all food groups.
• Variety ensures nutritional adequacy and prevents monotony.
• Make meals colourful and visually appealing.

4. Establish regular meal timings:

• Set fixed times for breakfast, lunch, dinner and snacks.
• Regular meal timings help regulate appetite and prevent overeating or skipping meals.
• Emphasise the importance of not skipping breakfast, as it provides energy for the school day.

5. Provide healthy snacks:

• Replace unhealthy snacks (chips, chocolates, soft drinks) with nutritious options like fruits, nuts, milk, sprouts and homemade snacks.
• Keep healthy snacks readily available at home.

6. Limit junk food and fast food:

• Explain to children why junk food (high in fat, sugar and salt) is harmful.
• Limit eating out and consumption of processed foods.
• Teach children to read food labels.

7. Educate children about nutrition:

• Teach children about the importance of different nutrients and food groups in simple, age-appropriate language.
• Use stories, games and activities to make nutrition education interesting.

8. Create a positive eating environment:

• Eat meals together as a family whenever possible.
• Avoid distractions like television or mobile phones during meals.
• Make mealtimes pleasant and stress-free.

9. Encourage adequate water intake:

• Teach children to drink sufficient water throughout the day instead of sugary drinks.

10. Limit screen time and encourage physical activity:

• Reduce sedentary behaviour (TV, video games) and encourage outdoor play and sports.
• Physical activity increases appetite and helps maintain a healthy weight.

Conclusion: Developing healthy food habits in school-going children requires consistent effort from parents, teachers and the school environment. Habits formed during these years are likely to persist throughout life.

Given: Helping children with special needs (children with physical, mental or developmental disabilities) with nutritional issues.

Aspects to be considered:

(i) Observation:

• Careful and continuous observation of the child is the first and most important step.
• Observe the child's eating behaviour — how much the child eats, how long it takes, whether the child shows interest in food or refuses certain foods.
• Observe for signs of nutritional deficiencies — pale skin (anaemia), poor growth, dental problems, fatigue, etc.
• Note any food allergies or intolerances — rashes, vomiting, diarrhoea after eating certain foods.
• Observe the child's chewing and swallowing ability, as some children with special needs (e.g., cerebral palsy) may have difficulty with these.
• Observations should be shared with healthcare professionals (doctor, dietitian) to plan appropriate nutritional interventions.

(ii) Physical activity:

• The level of physical activity of a child with special needs varies greatly depending on the nature and severity of the disability.
• Energy requirements must be adjusted according to the child's activity level — a child who is physically inactive needs fewer calories, while a child who is hyperactive may need more.
• Encourage appropriate physical activity within the child's capabilities, as it improves appetite, muscle strength, bone density and overall well-being.
• For children with mobility limitations, physiotherapy exercises may be recommended.
• Physical activity also helps prevent obesity, which is a common problem in children with certain disabilities (e.g., Down syndrome).

(iii) Developing eating skills:

• Many children with special needs have difficulty with self-feeding due to poor motor coordination, muscle weakness or cognitive limitations.
• Occupational therapy can help develop fine motor skills needed for self-feeding (holding a spoon, cup, etc.).
• Use adaptive utensils (specially designed spoons, cups, plates with suction bases) to make self-feeding easier.
• Teach eating skills step by step, with patience and positive reinforcement.
• For children with swallowing difficulties (dysphagia), food should be of appropriate texture (pureed, minced or soft) to prevent choking.
• Developing eating skills promotes the child's independence and self-esteem.

(iv) Variety:

• Children with special needs may be selective eaters or have strong food preferences/aversions due to sensory sensitivities (e.g., children with autism may be sensitive to food textures, colours or smells).
• Despite these challenges, it is important to offer a variety of nutritious foods to ensure all nutrients are obtained.
• Introduce new foods gradually and patiently, without forcing the child.
• Experiment with different textures, colours and presentations to make food more acceptable.
• Variety in diet prevents nutritional deficiencies and makes meals more interesting.
• Consult a dietitian if the child's food preferences are severely limited.

(v) Special diets:

• Some children with special needs require specific therapeutic diets based on their medical condition:
• Phenylketonuria (PKU): A low-phenylalanine diet is required.
• Coeliac disease: A gluten-free diet (avoiding wheat, barley, rye) is essential.
• Diabetes: A controlled carbohydrate diet with regular meal timings is needed.
• Food allergies: Strict avoidance of the allergen (e.g., nut-free, dairy-free diet).
• Epilepsy: A ketogenic diet (high fat, low carbohydrate) may be prescribed in some cases.
• Special diets should always be planned by a qualified dietitian or doctor to ensure they are nutritionally complete.
• Parents and caregivers should be trained to prepare and provide the special diet correctly.
• Regular monitoring and follow-up with healthcare professionals is essential.

Conclusion: Addressing the nutritional needs of children with special needs requires a holistic, individualised approach involving careful observation, appropriate physical activity, skill development, dietary variety and medically supervised special diets.

Given: The influence of family, media and peers on children's food intake.

1. Influence of Family:

Family is the most important and earliest influence on a child's food habits.

• Role modelling: Children observe and imitate the eating habits of their parents and older siblings. If the family eats a balanced, nutritious diet, the child is likely to develop similar habits.
• Food availability: The foods that parents buy and keep at home determine what the child eats. If healthy foods are readily available, the child will eat them.
• Feeding practices: How parents feed the child — whether they force-feed, restrict certain foods or allow the child to self-regulate — affects the child's relationship with food.
• Cultural and religious practices: Family food traditions, cultural preferences and religious dietary restrictions shape the child's food choices (e.g., vegetarian diet, fasting practices).
• Meal environment: Eating together as a family, having regular meal timings and creating a positive, stress-free meal environment encourages healthy eating.
• Socioeconomic status: The family's income determines the variety and quality of food available to the child. Low-income families may not be able to afford a diverse, nutritious diet.

2. Influence of Media:

Media (television, internet, social media, advertisements) has a powerful influence on children's food choices.

• Advertising of junk food: Children are heavily targeted by advertisements for fast food, soft drinks, chocolates, chips and other unhealthy foods. These advertisements use attractive visuals, cartoon characters and celebrity endorsements to appeal to children.
• Creating demand: Repeated exposure to food advertisements creates a desire in children to consume these products, often overriding parental guidance.
• Unrealistic body image: Media can also promote unrealistic body images, leading some children to adopt unhealthy eating behaviours (skipping meals, crash dieting).
• Positive influence: Media can also be used positively — educational programmes, health campaigns and social media content promoting healthy eating can encourage children to make better food choices.
• Screen time and sedentary behaviour: Excessive screen time is associated with increased snacking on unhealthy foods while watching TV or using devices.

3. Influence of Peers:

As children grow older, especially during school age, peer influence on food choices becomes increasingly important.

• Social acceptance: Children want to fit in with their peer group. If peers eat certain foods (e.g., fast food, chips), the child may feel pressured to eat the same to be accepted.
• Eating at school: The school canteen, tiffin sharing and eating with friends expose children to a variety of foods. Positive peer influence can encourage trying new healthy foods.
• Negative peer pressure: Peers may mock children who bring healthy home-cooked food or who do not eat junk food, leading children to abandon healthy eating habits.
• Food trends: Food trends popular among peers (e.g., a particular fast food item or beverage) can strongly influence what children want to eat.
• Positive peer influence: If healthy eating is promoted as 'cool' within the peer group or school environment, children are more likely to adopt healthy food habits.

Conclusion: Family, media and peers all play significant roles in shaping children's food intake. While family provides the foundation of healthy eating habits, media and peers can either reinforce or undermine these habits. It is important for parents, schools and policymakers to work together to create an environment that supports healthy food choices for children.
