Health benefits of olive oil
Over and over again, hundreds of
researches all over the world have demonstrated that
the olive oil helps to reduce heart disease and
many other positive effects on your health.
Olive oil is known to
help reduce LDL (Low Density Lipoprotein), or bad
cholesterol. It has positive effects on risk factors
for diseases like diabetes, and on the gastrointestinal functions and is
rich in anti-oxidants.
Is olive oil truly good for your
diet?
Olive oil is a naturally good
food. It is the only edible oil that is
produced by simply squeezing the olive fruit without heat or
further processing. It has
positive effects on the level of cholesterol in the body. In fact, it is
one of the vegetable oils that help to conserve
“good cholesterol” (HDL) and to reduce the “bad cholesterol”
(LDL), preventing the risk of hearth diseases.
Has olive oil bad side effects?
With references to the most recent
dietetic recommendations olive oil has no bad side effectsr. Naturally, a balanced diet
all classes of foods would have to be
represented (all cereals, vegetables, fruit, legumes, milk and
dairy, fish, meats, and oils), in the right
proportions. Also in the effort
to lose weight we have to control the total caloric
contribution of each food we eat and not the fat intake.
What "free-radicals" are and is it
true that olive oil neutralizes them?
Free radicals are
chemical compounds that are electronically unbalanced which
are highly reactive molecules and are products of incomplete reaction in the metabolism of oxygen that, when
in excess, can be highly dangerous to our bodies. The
lipids (fats) contained in our bodies are subject to oxidation and
the production of free radicals which can then reach the
status of rancidness, bad smell and the loss of nutritional
valences. Olive oil has the
remarkable advantage of being composed mostly of oleic acid
which is less
vulnerable to these phenomena, and contains natural
anti-oxidants that can protect from
the attack of the free radicals.
Does olive oil makes you fatter?
No, There is the common misconception
that the fat you eat equals the fat in your body. This is very far from
true. Most of the fat in our bodies comes from sugars and
carbohydrates. This happens because sugar is
immediately absorbed into the blood stream. Since our bodies
have to limit the sugar level, the excess of sugar is stored
in the liver to be eventually used later. Since we
continue to eat ( we sure do not wait for starvation)
this sugar will not be used and our body starts the process
of long term storage that means transforming sugar into fat.
On
the other hand, fats are digested slowly so they are put in
use as soon as they are available. Fats are essential in our
diet. The lipids, or fats, have many functions:
constitutional, being part of the composition of biological
membranes and going to form some hormones, and energetic,
representing a reservoir of energy always on hand in the
body. The lipids represent the best source
of energy. For instance, each gram of proteins or
carbohydrates (starch or sugars) gives approximately 4 kcal
(kilocalorie); while one gram of lipids gives about 9 kcal.
There is a lot of talking about olive
oil and prevention of cardiovascular disease. Is this true?
and why?
The greater part of
studies for the prevention of chronic arterial
degeneration (arteriosclerosis) and the consequent damage to
our health has demonstrated that it is possible to
reduce the total cholesterol and LDL, avoiding the successive
chain of injurious events, when fat acids (monounsaturated
or polyunsaturated) replace saturate fat acids
.
The olive oil, for its elevated content in
monounsaturated fat acids, constitutes an ideal
substitute for the saturated fats that are in excess in
the diet of western world populations, Therefore, olive
oil is one of the healthiest fats in our diet.
I’ve heard that olive oil
is an anti-oxidant. Why is that important?
Free radicals, which are produced for oxidation of various
substances, can cause damage to cells and therefore promote
the cardiovascular chronic-degenerate diseases and
carcinogenesis. Anti-oxidant substances have a protective
function that is particularly effective against free
radicals. Types of anti-oxidants are: vitamins A, E, and
C, and bioflavonoid. Polyphenols are also capable of blocking
free radicals. Olive oil is a natural source of anti-oxidants
– it contains vitamin E, falconoid, phenols and pirrolici
pigments. As you may be aware, the Mediterranean diet, for
years the center of attention of students, assures a good
contribution of anti-oxidants. Olive oil is just one of the
hinges of this positive alimentary model.
Is olive oil good in pregnancy?
Certainly. In pregnancy the diet does not differ
much from one corrected feeding of the people
generally There are some specific recommendations tied to the presence of a new organism
in formation: therefore, reasonable increase of the calorie totals , increment of the contribution in proteins and
attention to one adequate assumption of minerals and
vitamins. Together with the advice of milk and other
foods with high biological value
(meats, eggs, fish), veggies and fresh fruits (rich of
vitamins, minerals and fiber) it comes suggested to flavor
the dishes with olive oil, to ensure a quota of good
fat acid monounsaturated (oleic) and essential
fat acid (linoleic), necessary for an optimal development of
the nervous system of the new born.
Is olive oil good for children? and at
what age?
Of course. Since the age of the weaning, the
baby foods made up of cereals and meat,
with adding of grain or parmesan, shall be completed with
small amounts of fat as extra virgin olive oil. The olive oil will continue then to being for all
infancy and the adolescence as preferred dressing, because a
good amount good oleic acid, of easy digestion, and very
good for energy production , and of fat acids like the linoleic fundamental for the
growing organisms.
Is olive oil good for athletic people?
Yes. In the diet of who it makes sport,
also to agonistic levels, the
use of a olive oil dressing offers, beyond
to the nutritional guarantees of a natural product, the
advantage of an optimal digestibility. Compare to other
fats, the olive oil induces
in fact an express emptying of the stomach., shortening the
times of digestion; it help contrasting the
excess of gastric acidity, thanks to the stimulus exercised
on the secretion of able substances to mitigate it; it
stimulates the activity of the gall bladder, favoring in
such a way the emulsion and the digestion of the fat in the small intestine.
Is it olive oil good for the elderly?
We have already seen as it is
opportune to adopt such dietetic to favor the
maintenance of low levels of cholesterol in the blood,
without moreover to favor the formation of free radicals,
potentially injurious for the health; this is worth to all
the ages, but it is particular importance in the
advanced ages of life. The olive oil satisfies these
requirements at the same time assures the assumption of good
amount of fat (in a position to supplying optimal
contributions of calories) and some vitamins
(A, D, E, K)
normally through fat substances, of which easy in
the old the deficiency can be established, with damage for
the health. Not to then forget the aspect about the optimal
taste: to confer taste to the dishes can
only contribute to the improvement of the aliment of
the older subjects in which, for various reasons of health
and associate-economic nature, not very rarely it is
assisted to rebelling of diseases due to
nutritional deficiencies. The olive oil, at last, is easy
digestible and has a slightly an laxative action,
good in age in which commonly manifest of constipation.
Is olive oil good for the skin and
hair?
The health of the cute and its annexed
ones, like hair, depends in considerable way from a
corrected contribution in nourishing substances, from the
moment that, for definition, these tissues are, in our
organism, those mainly subject to an express regeneration.
The olive oil, with its essential fat acid content, that the
organism is not in a position to producing and with its
favoring action the absorption of many vitamins, represents
an ideal food, from this point of view, especially if consumed
as raw, in combination to veggies. The olive oil
moreover is a source of natural, precious anti-oxidants
against the free radicals, more and more often pointed as
cause cellular aging.
