Vegetable oil. Friend or foe?
has been written about the benefits of replacing animal
fats in the diet with vegetable oil and vegetable-derived

or peanut oil are pressed from the seeds. Still others,
such as herb oils are usually extracted from the leaves
or roots, often using steam or another heat source to aid

vegetable oils, such as olive oil have been in use for
thousand of years, and their benefits as part of a balanced
diet are well understood. In fact, most vegetable oils
are probably alright as part of a balanced diet and would
certainly be unlikely to do any harm (except in excessive
amounts) if it were not for the fact that they are chemically
altered before they are used.
oils now form a massive proportion of all the vegetable
oils used worldwide, but particularly in the Western world
and more especially North America. Whilst many liquid oils,
such as sunflower oil are largely unadulterated, the solid
forms of vegetable oils, such as margerine, shortening
and some liquid oils are chemically altered forms of the
natural oils, commonly known as hydrogenated
(explained here) changes
these oils from their natural state to a dangerous, unnatural
one which has major detrimental effects on health. If you
are concerned in any way about the fat in your diet (and,
as you ar reading this, I suspect you are!) you MUST understand
the effects that hydrogenated
oils have on the human body.
