    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.
