A brief description of fat and its effects on one's health.

2. Fats are one of the three
macronutrients along with
carbohydrates and proteins.
Fats that are liquid at room
temperature are called oils.
Fats are composed of three
fatty acid units and glycerol.

3. There are four types of fats:
• Saturated Fats
• Unsaturated Fats
• Trans Fat

4. Saturated fats are fat
molecules that have no
double bonds between the
carbon molecules because
they are saturated with
hydrogen molecules. They
are solidifed at room
temperature

5. Sources of Saturated Fats
Sources of Saturated Fats include:

6. Effects of Saturated Fats on health
Saturated Fats raises
cholesterol in your blood.
Cholesterol is a thick waxy
substance found in your
blood. High levels of
cholesterol in your blood
increases risks of heart
disease and stroke.

7. There are two types of
unsaturated fats:
• Monounsaturated Fats
• Polyunsaturated Fats

8. Monounsaturated fats
Monounsaturated fats are
simply fat molecules that
have one unsaturated
carbon bond in the
molecule, this is also called
a double bond. They are
usually found in oils.

9. Sources of Monounsaturated Fats
Sources of Monounsaturated Fats incude:

10. Effects of Monounsaturated Fats on health
Monounsaturated fats can
help reduce bad cholesterol
levels in your blood which
can lower your risk of heart
disease and stroke. They
also provide nutrients to help
develop and maintain your
body’s cells.

11. Polyunsaturated fats
• Polyunsaturated fats are
simply fat molecules that
have more than one
unsaturated carbon bond
in the molecule, this is also
called a double bond. Oils
that contain
polyunsaturated fats are
typically liquid at room
temperature

12. Sources of Polyunsaturated Fats
Sources of Polyunsaturated fats iclude:

13. Effect of Polyunsaturated Fats on health
• Polyunsaturated fats can
help reduce bad
cholesterol levels in your
blood which can lower
your risk of heart disease
and stroke. They also
provide nutrients to help
develop and maintain your
body’s cells.

14. Trans fat are a form of
unsaturated fat. There are
two types of trans fats
found in foods:
• Naturally-occuring trans fat
• Artificial trans fat

15. Naturally-occuring Trans Fat
Naturally-occurring trans fats
are produced in the gut of
some animals and foods
made from these
animals(eg. meat and milk
products) may contain small
quantities of these fats.

16. Artificial Trans Fat
Artificial trans fats (or trans
fatty acids) are created in
an industrial process called
hydrogenation.

17. Effect of Trans Fat on health
Trans fats raise your bad
(LDL) cholesterol levels and
lower your good (HDL)
cholesterol levels. Eating
trans fats increases your risk
of developing heart disease
and stroke. It’s also
associated with a higher risk
of developing type 2
diabetes.

18. 1. Hydrogenation is a process
in which a liquid unsaturated
fat is turned into a solid fat by
adding hydrogen. During this
manufactured partially
hydrogenated processing,
trans fat is made.

19. 2. Saponification- This is the
process whereby alkalis
break down fats into glycerol
a fatty acids(soap).
3. Rancidity- This is a
reaction that causes
unpleasant odours and
flavours in fats usually
caused by reactions with
oxygen, the action of
microbes and the action of
enzyme lipase on fats.
