Much attention has been focused on the need to limit dietary intake.
Nevertheless, the body does need fats – but the right fats and in
appropriate quantities. Specifically, it needs essential fatty acids,
which perform a variety of vital bodily functions.
Fatty acids in foods occur mainly in the form of esters with the alcohol
glycerol. The predominant esters are tricayglycerols accompanied by
minor amounts of mono- and diacylglycerols and free fatty acids.
Essential fatty acids profoundly influence the health of the human body,
including brain and immune system function. Essential fatty acids carry
the fat soluble vitamins. They are essential for growth and
development, and for the maintenance of healthy skin, hair and nails.
And they provide the body with energy. A variety of problems can occur
if the body fails to receive adequate amounts of essential fatty acids.
Signs of deficiency may include retarded growth; skin hair and nail
disorders; and an impaired metabolism of fats and fat soluble vitamins.
Two fatty acids that cannot be synthesized by the body and must be
provided by the diet: the essential fatty acids Linoleic acid and alpha
linolenic acid are polyunsaturated fatty acids. If the diet lacks
adequate amounts of either linoleic or alpha linolenic acid, deficiency
symptoms will develop that include scaly skin, hair loss, and slow wound
healing.
The importance of essential fatty acids in food
What does the term "diet" mean? The definition of a diet as the complete oral consumption of nutrients and non-nutritive substances is comprehensive yet lacks specificity. It is defined by the typical composition and allocation of nutrients and foods ingested by an individual or a specified group.
