Using of Cooking Oil
There are many different types of oils used in cooking. What are the various
types of oils best used for, and which are most healthy for you?
Many oil types give a distinctive flavor to their dishes, so a lot of this has
to do with what flavors you enjoy in your foods. Try getting a combination of
the various healthy oils and experiment with them to bring diversity to your
menu! Also note that most people get WAY too many Omega-6 oils in their diet and
not enough Omega-3s. The proper ratio should be 3:1 of 6 oils to 3 oils, instead
of the current average ratio of 10:1. So decrease the amounts of Omega-6s you
eat, and kick up the Omega-3 levels!
Be sure to follow the temperature guidelines. If you heat an oil too hot, it can
start to smoke, ruining your food and smoking out your home. Also, overheating
an oil can destroy its health benefits and even turn the healthy oils into trans
fatty acids. Omega-3s should be served cold. Omega-6s should be used under 212F.
Store oils in a dark cool place, and use within a year.

The healthiest oil to cook
with is one that is composed primarily of monounsaturated fat. Oils containing a
high degree saturated fats are considered the least healthy by most doctors,
though most doctors now feel that the naturally occurring saturated fats in
products like butter are better than the saturated fats in products like
margarine.
Contrary to popular belief, fat is actually a valuable part of one’s diet,
allowing people to absorb nutrients that require fat in order to metabolize in
the body. Healthy fat, mainly mono or polyunsaturated fat is a far better choice
than saturated fat
(Saturated fat
is one of the two main categories of fats that appear in foods. It is
distinguished from unsaturated
fat in that there are no double bonds between carbon
atoms in its chemical makeup, so that the fatty
acids are saturated with hydrogen.
Naturally occurring saturated
fat, such as the fat found in animal-based foods, congeals when cool, while
naturally occurring unsaturated fat, such as olive oil, remains fluid. Saturated
fat is less likely to spoil than unsaturated fat and more stable during cooking.
Saturated
fats are unhealthy in excess, but the consumption of small amounts of these oils
is essential.).
Most experts now agree that the healthiest oil to use is canola
oil. One drawback of canola oil is that it may not respond well to high
temperatures (Canola oil may be the
healthiest oil and best choice for baked, sweet goods because it has minimal
flavor) . Another good choice, and actually a frequent one is peanut
oil, which is also high in monounsaturated fat.
Olive
oil is considered by some to be the healthiest oil because it provides a mix
of monounsaturated and polyunsaturated fats. It can also be obtained in very
pure form, which most health experts recommend. Olive oil has a fairly high cooking
temperature, and is also a great flavor additive to savory dishes.
Most experts recommend using peanut oil for high temperature cooking, canola
oil or olive oil for medium temperature cooking, and a variety of
polyunsaturated oils for baked goods. In a way there is no “healthiest oil”
since each oil can offer different benefits and one may be a better choice than
another in a cooking process.
Is reusing cooking oil safe?
Reusing cooking oil has been done for ages. There really isn't a problem, if
done properly. The greatest hazard is allowing the fat to become rancid
(spoiled) and deteriorated to the point it produces undesirable flavors and
odors. Besides ruining what would have been a perfectly good meal, rancid oils
also contain free radicals that are potentially carcinogenic.
To understand how to best re-use oil, it is important to know about smoke
points — the temperatures at which oil begins to decompose. If you heat oil to
a temperature that is too high, it produces smoke fumes. Acreolin, a substance
that makes your eyes burn, is given off as well.
