Food, Nutrition, Health and Fitness Class 11 NCERT Book PDF Highlights
Food, Nutrition, Health and Fitness is the main nutrition chapter in Class 11 Home Science. It starts with the meaning of food, nutrition and nutrients, then moves to balanced diet, recommended dietary allowances, food groups and the food guide pyramid.
| NCERT area | Main idea | How to revise it |
|---|---|---|
| Food and nutrition | Food supplies nutrients that support health and activity | Learn the definitions first |
| Balanced diet | Correct variety and proportion of foods for daily needs | Connect it with RDA and safety margin |
| Food groups | Planning tool for choosing meals | Revise the food guide pyramid |
| Adolescent habits | Food choices change due to growth, peers and media | Use examples from daily life |
The safest short answer in this chapter defines the term first and then adds one meal or adolescent-life example.
Food, Nutrition and Nutrients in Chapter 3
NCERT defines food as any solid or liquid that is swallowed, digested and assimilated to provide nutrients. Nutrition is the science of food, nutrients and their action in the body. Nutrients include carbohydrates, proteins, fats, vitamins, minerals, water and fibre.
- Carbohydrates and fats: major energy-giving nutrients.
- Proteins: needed for growth and repair of tissues.
- Vitamins and minerals: protective and regulatory nutrients.

Balanced Diet and RDA in Class 11 Home Science
A balanced diet includes different foods in adequate amounts and correct proportions. It meets the day's needs for energy, body building, protection and regulation. NCERT also explains Recommended Dietary Allowances as requirement plus a margin of safety.
- Include cereals, pulses, milk, vegetables, fruits, fats and adequate water.
- Match food intake with age, sex, body size and activity.
- Use the food guide pyramid to avoid one-sided meals.
RDA is not the bare minimum. It includes a safety margin for short gaps in intake.
Health, Fitness and Food Groups in Chapter 3
The chapter links nutrition with health and fitness. Health is not only absence of disease. It includes physical, mental and social well-being. Fitness means the ability to do daily work, remain active and recover from exertion.
| Food group | Role in diet | Example |
|---|---|---|
| Cereals and millets | Energy | Rice, wheat, jowar |
| Pulses and animal foods | Protein | Dal, egg, fish |
| Milk and milk products | Protein and calcium | Milk, curd, paneer |
| Vegetables and fruits | Vitamins, minerals and fibre | Leafy vegetables, citrus fruits |
Adolescent Food Habits and Nutrition Risks
Adolescence brings a rapid growth spurt, so nutrient needs rise sharply. NCERT asks students to notice how peers, media, body image, pocket money and school routine affect food habits. Skipping meals, eating outside often and following extreme diets can disturb health.
- Anaemia: often linked with poor iron intake and fatigue.
- Obesity: linked with excess energy intake and low activity.
- Eating disorders: need early family, school and medical support.
For school answers, connect adolescent food habits with growth needs, peer pressure and body-image concerns.
