The document discusses nutrients and their importance for health. It defines nutrients as essential substances needed for growth and health, dividing them into caloric nutrients (carbohydrates, proteins, fats) and non-caloric nutrients (water, minerals, vitamins). Carbohydrates, proteins and fats are described in detail along with their functions, food sources and types. The document also covers water, minerals like calcium and iron, vitamin groups and specific vitamins. It discusses calories and provides recommendations for daily calorie and nutrient intake for teenagers. Finally, it describes the nutrition pyramid as a visual guide for healthy eating.
5. Complete proteins sources:
• Foods containing all the essential amino acids in the
correct proportion
Examples: meat, fish, eggs, milk, cheese
Incomplete proteins sources:
• Foods that are missing some essential amino acids
Examples: Legumes, nuts, whole grains

Proteins
12. Functions:
- Is the solvent in which all the chemical
reactions of the body take place
- transport of materials in the body by
making up most of the liquid part of
blood (plasma)
- helps to regulate body T
- helps to break down food
in the digestive system
14. The minerals and most of the
vitamins your body needs must be
obtained from the FOODS you
eat since your body cannot make
them.
15. Minerals
• Minerals are INORGANIC
substances required by your
body in order to develop and
grow:
Calcium Magnesium
Potassium Iron
16. Calcium
• Function: Helps to build
strong bones and teeth,
regulates blood clotting
• Food sources: dairy
products, leafy and green
vegetables
17. Iron
• Function: Helps to build
hemoglobin which is the
oxygen-carrying protein in
your red blood cells
• Food sources: eggs,
meats, whole grains
18. Potassium
• Function: Helps regulate fluid
balance in the body, assists with
the normal functioning of muscles
and nerves
• Food sources: bananas,
carrots, milk
19. Vitamins
Vitamins: Group of complex
compounds that help your
body maintain normal
metabolism, growth, and
development
21. Water- Soluble Vitamins:
• Vitamins that dissolve in
water and are NOT stored in
your body for future use
B Complex Vitamins
Vitamin C
22. Examples of Water-Soluble
Vitamins: Vitamin C
• Fights against infection,
maintains healthy gums,
strengthens and maintains blood
vessel structure
• Sources: citrus fruits, tomatoes,
leafy vegetables
23. B Complex vitamins :
• Help prevent birth defects, and
are needed in the formation of
red blood cells and nucleic acids
• Sources: broccoli, avocado,
meat and lentils
_
24. Fat-Soluble Vitamins:
• Vitamins that dissolve into and are
transported by fat
• They can be stored in fat tissue,
in the liver, and the kidneys
• Vitamins A, D, E, and K
25. Examples of Fat-Soluble
Vitamins:
• Vitamin A: Maintains good vision,
promotes body cell growth, helps
protect teeth
Food sources:
green vegetables, dairy products
26. • Vitamin D: Promotes the
development of healthy bones
and teeth
–Food sources: eggs, fish,
fortified breakfast cereal
– Sunlight stimulates
–our skin to produce it
31. So, why is it shaped like a pyramid?
The base or the bottom of the pyramid is the grain, cereal
and bread group. We need 6 to 11 servings of this group.
The most of any of them. If you were to make a pyramid
out of Tater Tots you would put the most on the bottom to
support all the rest.
From USDA
• The base or the bottom of the pyramid is
the grain, cereal and bread group.
• The next layer up is the fruits and
vegetables group.You need 2 to 4 servings of
the fruits and 3 to 5 servings of the
vegetables.
33. The next layer is the dairy and the protein
groups. We need 2 to 3 servings a day of the
dairy group and 2 to 3 servings of the protein
group.
The tip-top of the pyramid is the sugar, fats,
and salt group. Guess what? We don’t need to
make choices for that group because if we eat
other foods, we get all the fats, sugars and
salt our bodies needs.
34. • Maybe you’re too tired to do your work
at school,
• Or it takes longer to get over a cold,
• Cuts and injuries might
take longer to heal,
• You’re cranky.
If you don't use a proper diet, little
things might happen like:

35. In the long run if we don’t
choose a healthy diet we have a
greater chance of getting some
bad diseases like:
• Heart disease
• Diabetes
• Obesity
