Health and Human Development - Fats or lipids

Fats or lipids

Fats are a very concentrated source of energy and are the form in which
energy is stored in the body. Fats provide the essential fatty acids,
linoleic, an omega-6 fatty acid and linolenic, an omega-3 fatty acid.
Recent research has indicated a need for those in the Western world to
increase their intake of these to improve cardiovascular health, and they
appear to have some role in improving brain development in infants. These
essential fatty acids assist in the absorption and transport of the
fat-soluble vitamins A, D and E. Subcutaneous fat gives the body its soft
curves or shape and insulates the body, assisting in the maintenance of
body temperature.

Seen only in cases of starvation or extreme dieting for weight loss,
although low intakes of the essential fatty acids may prevent optimal
health from being achieved.

Found in non-trimmed meat, fried foods, cakes, biscuits, pastries and
chocolate.

Found only in animal fats.

Found in vegetable oils, fish oils and nuts.

The omega-3 fatty acids are found mainly in fish oils and some nut oils.
Omega-3 has been added to High Q bread and some eggs have been especially
produced to contain higher omega-3 content.
