Study Notes
Starch
- Found in foods like rice, potatoes, bread, cereals, noodles, yam, cassava, beans, and grains.
- Different cultures derive carbohydrates from various sources:
- Western: Potatoes, bread, vegetables, meat.
- Malay: Rice, fish, vegetables.
- Chinese: Rice, meat, vegetables.
- Indian: Rice, vegetables.
- Italian: Pasta, bread, vegetables.
- Testing for starch involves iodine solution; a blue-black color indicates starch presence.
Sugars
- Natural sources include fruits, sugar cane, and milk.
- Used in making chocolates, candies, cakes, and soft drinks.
- Refined sugars provide energy with minimal nutrients, excessive intake is unhealthy.
- Surplus carbohydrates convert to fats and are stored in the body.
Fats
- Provide energy and are stored for long periods.
- Found in milk, butter, cheese, nuts, oils, meat, and egg yolk.
- Necessary for healthy growth and development.
Testing for Fats
- Brown paper test: A translucent spot forms on the paper when fat is present.
Fibre
- Composed of cellulose, unbreakable by the human body.
- Essential for digestive health, helps prevent constipation.
- Rich sources: Fruits, vegetables, brown rice, cereals, whole wheat bread.
Vitamins
- Essential for health in small amounts; deficiencies can lead to diseases like scurvy (Vitamin C deficiency) and rickets (Vitamin D deficiency).
Minerals
- Vital for growth and development in minute quantities.
- Important minerals and their functions:
- Calcium: Strong bones and teeth; found in dairy, greens, eggs.
- Iron: Forms hemoglobin; found in liver, meat, eggs, greens.
- Iodine: Produces thyroid hormones; found in seafood, greens, iodized salt.
- Sodium: Regulates body fluids; found in common salt.
Water
- Constitutes about 70% of body mass; essential for food breakdown, nutrient transport, and chemical reactions.
- Daily requirement: Approximately 2-3 liters (6-8 glasses).
- Water is also obtained from juicy fruits.
Energy Value of Food
- Main energy contributors: Carbohydrates, fats, and proteins.
- Energy values:
- Carbohydrates: 17 kJ/g
- Fats: 37 kJ/g
- Proteins: 17 kJ/g.
- Carbohydrates are the primary energy source; fats are secondary; proteins serve as a last resort.
Testing for Glucose
- Glucose presence indicated by Benedict’s solution, transitioning from blue to an orange-red precipitate upon heating.
Protein
- Composed of amino acids; essential for cell, tissue, enzyme, and hormone production.
- Deficiency leads to kwashiorkor, characterized by muscle wasting and distended belly.
- Protein-rich foods include meat, eggs, fish, milk, cheese, beans, nuts, and peas.
Testing for Proteins
- Biuret solution turns violet in the presence of soluble proteins.
Summary of Key Nutrients
- Key nutrient categories: Carbohydrates, fats, proteins, fibre, vitamins, minerals, water.
- Most foods contain a combination of these nutrients, but some are richer in specific nutrients than others.
