Omega -3 & Omega -6 acids and their

Health Effects

Omega-3 fatty acids are essential fatty acids, a class of

nutrients needed for our body to function normally.

These are the fats of life which help our cells to

function properly.

Omega-3 cannot be produced be our body and should

be supplied through the diet

Types of Omega-3 acids

There are 3 very important types of Omega 3 acids

1.Alpha-linolenic acid (ALA)

2.Eicosapentaenoic acid (EPA)

3.Docosahexaenoic acid (DHA)

which have amazing health benefits

Alpha-linolenic acid

α-Linolenic acid is an n−3 fatty acid. It is one of twoessential fatty acids, so called because they arenecessary for health and cannot be producedwithin the human body.

Eicosapentaenoic acid

Eicosapentaenoic acid is an omega-3 fatty acid. In

physiological literature, it is given the name 20:5. It

also has the trivial name timnodonic acid.

Docosahexaenoic acid

Docosahexaenoic acid is an omega-3 fatty acid that is aprimary structural component of the human brain,cerebral cortex, skin, sperm, testicles and retina.

Functions of Omega-3 fats

Omega 3 plays a major role in a number of functions in

our body. Here are they:-

Relaxation and contraction of muscles

Blood clotting

Digestion

density lipoproteins) in the blood. (LDL cholesterol is

the "bad" cholesterol.
