The document discusses the basics of nutrition and health promotion. It defines nutrients as substances that provide nourishment essential for life and growth. The major components of food that are nutrients include carbohydrates, proteins, fats, vitamins, minerals, water, and fiber. Each component is described in terms of its functions and major food sources. Carbohydrates, proteins, and fats provide energy, aid growth and cell formation, and have other roles. Vitamins and minerals help regulate body processes and allow growth through their roles in digestion, metabolism, hormone production and other functions. Water is essential for life processes and helps absorb nutrients, while fiber aids digestion.

COMPONENTS OF FOOD

6. Food Groups

7. Proteins are very important for our body.
• It helps in repairing worn out tissues.
• If we don’t have proteins in our body, cells will be damaged.
• Proteins helps in the formation of hair, nails etc. They are body building
foods.
PROTEINS

8. • Proteins can be animal proteins and
plant proteins.
• Animal protein rich food include eggs,
fish, meat, milk, cheese and pulses.
• Plant protein rich food include pulses
of beans.
• Food rich in proteins include lean
meat, fish, eggs, milk, cheese, nuts,
beans, peas, etc

9. • Carbohydrates are made up of carbon, hydrogen and oxygen atoms.
• They are important because :
1. All organisms use them for energy.
2. Reserve food materials.
3. Formation of cell
4. Organelle and cell compounds
CARBOHYDRATES

10. • Vegetables
• Beans
• Fruits
• Rice
• Grains (wheat, oats, millets)
CARBOHYDRATES – Sources

11. • Is a nutrient.
• Is a source of energy.
• Adds taste and texture to food.
• Helps absorbs fat soluble vitamins
• FUNCTIONS:
• Fats gives us energy. It gives much more energy than carbohydrates.
FATS

12. • Oil,
• Ghee,
• Milk,
• Butter,
• Eggs,
• Meat
FATS – Sources

13. • Compounds needed in
• small amounts to regulate body
processes and allow growth.
FUNCTIONS:
• Digestion
• Absorption
• Metabolism
VITAMINS

14. VITAMINS – Sources

15. • Naturally occurring inorganic substances.
FUNCTIONS:
• Catalyst for many biological reactions within the body.
• Production of hormones.
• Structural functions
• Acid base and water balance
MINERALS

16. • Animal foods are best sources
of Calcium, Iron and zinc. (milk,
meats)
• Plant foods are good sources of
potassium and magnesium.
(whole grain, cereal)
MINERALS – Sources

17. • A major portion of our body is formed of water.
• It helps our body to absorb nutrients from food.
• It is essential for most of the life processes or body functions.
• It is also helps in throwing out some wastes from body as urine and
sweat
WATER

18. • We drink water directly as well as
we receive water from milk, tea,
fruits, vegetables, cold drinks etc.
WATER – Sources

19. • Dietary fibre is that part of the food that cannot be digested by human
enzymes.
FUNCTIONS:
• Prevents constipation.
• Adds bulk to assist in peristalsis.
• Absorbs water /retains water therefore softer faeces for easy
defecation
