- Staying hydrated is important; drink plenty of water daily.
- Avoid overeating, junk food, and maintain fixed meal times.
- Rinse the mouth after eating to maintain oral hygiene.
Cooking and Food Preservation
- Cooking methods include boiling, steaming, and frying to make food digestible and appetizing.
- Half-cooked foods are harder to chew, so proper cooking is necessary for digestibility.
- Preservation methods include refrigeration (slowing spoilage), canning (sealing food in airtight containers), boiling (killing germs), and drying (removing moisture to inhibit bacterial growth).
- Spoilage can be demonstrated through experiments, such as leaving bread outside versus refrigerated.
Importance of Food
- Food is essential for growth, development, and survival of all living beings.
- It provides energy required for various bodily functions and protects against diseases.
Nutrients in Food

Roughage and Water
- Roughage is required for normal body functioning and aids in digestion.
- Water, though not a nutrient, is crucial for digestive processes and waste removal; it constitutes about 75% of body weight.
Digestion Process
- Digestion is the breakdown of food into simpler substances.
- It involves multiple organs in the digestive system: mouth, food pipe, stomach, small intestine, and large intestine.
Digestive Organs and Their Functions
- Mouth: Ingestion occurs here, with teeth grinding food and saliva breaking down carbohydrates.
- Food Pipe: Transports food from the mouth to the stomach.
- Stomach: Mixes food with digestive juices, breaking it down further over three hours.
- Small Intestine: Main site for nutrient absorption.
- Large Intestine: Absorbs water from undigested food.
Balanced Diet
- A balanced diet contains the correct proportion of nutrients from various food groups.
- No single food contains all essential nutrients, necessitating a diverse diet for optimal health.
Key Facts
- Carbohydrates are primary energy sources for the body.
- People engaged in physical activities need higher carbohydrate intake due to increased energy demands.
- Enzymes, secreted by glands, expedite the digestion process.
Dietary Recommendations
- Daily diet should include a variety of foods from all nutrient groups to maintain health.
- Light protein foods such as pulses and porridge are beneficial for digestion.
- Regular intake of fresh fruits and vegetables is crucial for a nutrient-rich diet.
Quick Check Questions
- Differentiate between ingestion and egestion in the context of food consumption.
- Identify the largest gland in the human body: the liver.
- Understand the role and partitioning of nutrients in the digestive process, focusing on how they interact within the digestive system.
Nutritional Essentials
- Proteins are vital for repairing damaged cells in the body.
- Key sources of protein include eggs, fish, cheese, milk, and chicken.
- Fats provide more energy than carbohydrates and contribute to skin health.
- Common fat sources are oil, ghee, butter, and nuts.
Importance of Vitamins and Minerals
- Vitamins play a crucial role in growth and body maintenance. Essential vitamins include A, C, D, E, K, and B-complex.
- Minerals, such as iodine, are important for processes like blood formation. Iodised salt and fish are good sources of iodine.
Role of Water
- Water, while not a nutrient, is essential for digestion and waste removal. It constitutes up to 75% of body weight.
Digestive Process
- Digestion is the breakdown of food into simpler substances.
- Ingestion happens in the mouth, aided by teeth, tongue, and salivary glands.
- Saliva begins breaking down carbohydrates into sugars, making starchy foods taste sweet when chewed.
Digestive System Components
- The food pipe transports food from the mouth to the stomach.
- The stomach is a muscular organ where food is stored and chemically processed for three hours.
- Most nutrient absorption occurs in the small intestine; waste water is absorbed in the large intestine.
Balanced Diet
- A balanced diet includes the correct proportions of all nutrient groups: carbohydrates, fats, proteins, vitamins, and minerals.
- No single food contains all nutrients; therefore, variety in the diet is essential.
Food Preservation Methods
- Refrigeration slows spoilage of food items like milk, bread, and fruits.
- Canning prevents bacterial growth by sealing foods in airtight containers.
- Boiling at high temperatures can kill germs, preserving liquids like milk.
- Drying reduces moisture in vegetables, thus extending shelf life.
Quick Checks and Concepts
- Ingestion: Taking in food through the mouth.
- Enzymes: Juices that aid in food digestion.
- Shelf Life: Duration a food product remains safe to consume.
- Always store food properly to avoid spoilage and maintain its nutritional value.
Nutritional Elements and Their Sources
- Essential amino acids (EAA) are crucial for protein formation; sources include egg yolk, soya beans, and certain vegetables.
- Minerals like iodine are vital for protein synthesis, primarily obtained from iodised salt and fish.
- Calcium is essential for bone health, sourced from milk, fish, green leafy vegetables, and a variety of green vegetables.
Role of Water
- Water makes up approximately 75% of body weight and is essential for bodily functions despite being a non-nutrient.
- Facilitates digestion and waste removal; 8-10 glasses of water are recommended daily to compensate for loss.
Food Requirements by Demographics
- Dietary needs vary by age and activity level; infants primarily consume milk.
- Growing children require energy-dense foods rich in carbohydrates, fats, and proteins due to increased activity.
- Adults need energy-rich foods but less protein as they do not grow further in size.
- Older adults require fewer calories due to decreased physical activity; diets should be balanced with fruits, vegetables, and light proteins.
Importance of Roughage
- Roughage, or dietary fiber, comes from leafy vegetables and cereals, aiding in digestive health.
- It is indigestible but necessary for preventing constipation and promoting regular bowel movements.
Digestion Process
- Food digestion involves breaking down complex substances into simpler forms through the digestive system, involving organs like the mouth, stomach, and intestines.
- Intestinal juices contribute to the digestion in the small intestine, while the large intestine absorbs water and forms semi-solid waste.
Balanced Diet
- A balanced diet includes necessary nutrients in appropriate proportions and requires consuming a variety of foods since no single food provides all nutrients.
- Healthy eating habits include consuming fruits and vegetables daily, drinking ample water, not overeating, and avoiding junk food.
Cooking Methods and Benefits
- Different cooking methods include boiling, steaming, frying, baking, and roasting; proper cooking enhances flavor and aids digestion.
- Overcooking should be avoided to preserve nutrients; nutrients can be retained by using water from soaked pulses.
Food Preservation
- Food preservation prevents spoilage caused by microorganisms, extending shelf life and maintaining the nutritional value.
- Proper food handling practices include washing fruits and vegetables before consumption to prevent contamination and nutrient loss.
- Covered food minimizes the risk of germ contamination and reduces waste.
