Food is essential for life, providing energy and materials for growth. This note covers the nutrients that constitute our food and their roles.
Food consists of various components called nutrients, each with specific functions in the body.
This chapter introduces the basic sources of our daily food. Food provides energy, supports growth, and maintains health.
These notes align with NCERT and CBSE syllabus for easy understanding.

Nutrients are substances in food that our body needs to function properly. They are classified into several types based on their roles.
Carbohydrates are the primary source of energy. They include sugars, starches, and fibres. Sources: rice, wheat, potatoes, and fruits. They provide quick energy and are vital for daily activities.
Proteins are building blocks for the body, used for growth and repair of tissues. They are made of amino acids. Sources: milk, eggs, meat, pulses, and nuts. Deficiency can lead to stunted growth.
Fats provide concentrated energy and help absorb fat-soluble vitamins. They insulate the body and protect organs. Sources: oils, butter, ghee, and nuts. Excess fat can cause health issues.
Vitamins are organic compounds needed in small amounts for various metabolic processes. For example, Vitamin A for vision, Vitamin C for immunity, and Vitamin D for bone health. Sources: fruits, vegetables, and sunlight.
Minerals are inorganic elements essential for body functions. Calcium for strong bones, iron for blood, and iodine for thyroid function. Sources: dairy products, leafy greens, and salt.
Water is crucial for digestion, nutrient transport, and temperature regulation. It makes up most of our body weight. Drink plenty of water daily to stay hydrated.
Fibre adds bulk to food, aiding digestion and preventing constipation. It is found in whole grains, fruits, and vegetables. It helps maintain a healthy digestive system.
A balanced diet contains all nutrients in the right proportions according to age, gender, and activity level. It includes a variety of foods from different groups to ensure proper health and prevent deficiencies.
Lack of specific nutrients leads to diseases. Examples:
Eating a diverse diet can prevent these conditions.
Developing healthy eating habits from childhood ensures proper growth, boosts immunity, and reduces the risk of chronic diseases. Encourage consumption of fresh, whole foods over processed items.
Food components like carbohydrates, proteins, fats, vitamins, minerals, water, and fibre are vital for health. A balanced diet incorporating all these nutrients is key to well-being for Class 6 students.
Food is any substance consumed by living organisms for energy, nutrients, and growth. Humans obtain food from various sources, mainly plants and animals. Learning about these sources is key to science and nutrition.
Food can be categorized into two main sources: plants and animals. Each offers diverse items that form our daily diet.
Plants produce their own food via photosynthesis. We depend on plants directly or indirectly. Different plant parts are eaten:
Plants also provide spices, oils, and beverages.
Animals give us various food products:
Other animal products are eaten in different cultures.
Animals are grouped by their diet:
This helps understand food chains and ecosystems.
To reinforce concepts, students can:
Practical activities make science engaging and memorable.
Knowing food sources promotes balanced diets and environmental awareness. This chapter builds a foundation for biology and nutrition studies, highlighting life's interconnectedness.
