The document discusses different types of fat found in foods, including saturated, unsaturated, trans, monounsaturated, polyunsaturated, omega-3 and omega-6 fatty acids. It provides information on the health effects of these fats, noting that saturated fats can raise cholesterol levels while unsaturated fats may help improve cholesterol levels. Examples are given of foods that contain different types of fats.

2.  FAT
The foods we eat contain nutrients that provide
energy and other substances the body needs .
The body uses fat as a fuel source
TYPES OF FAT
1Saturated fat
2.Unsaturated fat
3.trans fat

3.  What are saturated fats?
 From a chemical standpoint, saturated fats are
simply fat molecules that have no double bonds
between carbon molecules because they are
saturated with hydrogen molecules. Saturated
fats are typically solid at room temperature
How do saturated fats affect my health?
 Replacing foods that are high in saturated fat
with healthier options can lower blood
cholesterol levels and improve lipid profiles

4.  What foods contain saturated fats?
 lamb,
 fatty beef,
 pork,
 poultry with skin,
 beef fat (tallow),
 lard and cream,
 butter,
 cheese and
 other dairy products made from whole or reduced-fat
(2 percent) milk

5.  conflicting information about saturated fats
 The American Heart Association recommends limiting
saturated fats – which are found in butter, cheese, red
meat and other animal-based foods. Decades of sound
science has proven it can raise your bad cholesterol
and put you at higher risk for heart disease

6. 
Unsaturated fat
 Unsaturated fat is liquid at room temperature. It is
mostly in oils from plants. If you eat unsaturated fat
instead of saturated fat, it may help improve your
cholesterol levels. Try to eat mostly unsaturated fats.
Monounsaturated fat and polyunsaturated fat are
types of unsaturated fat.

7. Monounsaturated fat
This fat is in avocado, nuts, and vegetable oils, such
as canola, olive, and peanut oils. Eating foods that
are high in monounsaturated fats may help lower
your "bad" LDL cholesterol. Monounsaturated fats
may also keep "good" HDL cholesterol levels high.
But eating more unsaturated fat without cutting back
on saturated fat may not lower your cholesterol

8. Polyunsaturated fat
 This type of fat is mainly in vegetable oils such as
safflower, sunflower, sesame, soybean, and corn
oils. Polyunsaturated fat is also the main fat found
in seafood. Eating polyunsaturated fat in place of
saturated fat may lower LDL cholesterol. The two
types of polyunsaturated fats are omega-3 and
omega-6 fatty acids.

9. Omega-3 fatty acids
 are found in foods from plants like soybean oil,
canola oil, walnuts, and flaxseed. They are also
found in fatty fish and shellfish as
eicosapentaenoic acid (EPA) and
docosahexaenoic acid (DHA). Salmon,
anchovies, herring, sardines, Pacific oysters,
trout, Atlantic mackerel, and Pacific mackerel
are high in EPA and DHA and lower in
mercury. A healthy diet includes 8 ounces or
more of these types of fish a week, averaging
250 mg a day of these omega-3 fatty acids.

10. Omega-6 fatty acids
 Omega-6 fatty acids are found
mostly in liquid vegetable oils like
soybean oil, corn oil, and
safflower oil.

11.  Omega-3 fatty acid caution
 Children and pregnant and nursing women usually
have very low CVD risk but may be at higher risk of
exposure to excessive mercury from fish. Avoiding
potentially contaminated fish is a higher priority for
these groups.
 For middle-aged and older men and for women after
menopause, the benefits of eating fish far outweigh the
risks when consumed according to the guidelines of
the US Food and Drug Administration and
Environmental Protection Agency.
 Eating a variety of fish will help minimize any
potentially adverse effects due to environmental
pollutants
