Stew is a very important part of foods eaten in Nigerian cities. Here, it is used to eat special delicacies e.g. rice. Some also use it to eat amala, eba, fufu and even bread. Stew can be fried with a variety of oils; however, in Nigeria, the two kinds of oil mostly used are palm oil and groundnut or vegetable oil. Even though, traditionally, palm oil pre-dates groundnut oil, the latter seems to be used more than the former.
The Power Of Palm Oil
Palm oil is naturally reddish because it
contains a high amount of beta-carotene (though steaming palm oil may destroy the
beta-carotene, rendering the oil colourless), which helps the eye to fight
infections. Palm oil is one of the few vegetable oils relatively high
in saturated fats (just like palm kernel oil and coconut oil). It is thus
semi-solid at typical temperate climate room temperatures, though it will more
often appear as liquid in warmer countries.
The Nutritional Content Of Palm Oil
Palm oil contains several saturated
and unsaturated fats in the forms of lauric (0.1%, saturated), myristic
(0.1%, saturated), palmitic (44%, saturated), stearic (5%, saturated), oleic
(39%, monounsaturated), linoleic (10%, polyunsaturated), and linolenic (0.3%,
polyunsaturated) acids. Like any vegetable oils, palm oil is designated as
cholesterol-free, though saturated fat intake increases
cholesterol.
Palm oil is a very common cooking ingredient in southeast Asia and the tropical
belt of Africa. Its increasing use in the commercial food industry in other
parts of the world is buoyed by its cheaper pricing and the high oxidative
stability of the refined product.
The Health Benefits
Of Groundnut Oil
Groundnuts are rich in nutrients like
Protein, Fat, Vitamins and Minerals. Vitamin E present in Groundnuts acts
as antioxidants in the body and fight against free radicals providing various
anti-ageing benefits. Many other advantages of Groundnuts or
Groundnut oils are discussed in the following paragraphs.
Refined And Cold Pressed Groundnut Oil
However, before discussing the benefits of
Groundnut Oil, we must take into account the two major types of Groundnut oil
viz- Refined Groundnut Oil and Cold Pressed Groundnut Oil. All of us have heard
of these two types. So what are they and how exactly do the benefits differ
between the two of them?
Refined Groundnut Oil is extracted using very
high temperatures (up to 200 degrees Celsius) at machines in factories. Further
to extraction, the oil undergoes several processing methods including chemical
additives to refine, bleach and deodorize the oil. This results in an oil that
is devoid of any nutrients, flavours and aroma. The extreme processing can also
result in introduction of Trans Fats in the oil which are harmful to health.
Cold pressed groundnut oil, on the other hand, is extracted at temperatures below 60 degree
Celsius by applying mechanical pressure to the Groundnuts. This method helps in
preserving the natural aroma, flavours and nutrients of the oil.
So We Will Now Focus This Discussion On Cold Pressed Groundnut Oil
The nutrition composition of Cold Pressed
Groundnut Oil is as follows:
Besides its Macro-nutrients, Peanut oil is also
rich in micronutrients like Vitamin E, Phytosterols and Omega-6 Fatty
Acids,
Owing to Its nutritional composition, Groundnut Oil has the following
health benefits:
- Heart Health
Various scientific researches have shown that
using Groundnut oil for cooking purposes may improve heart health and reduce
chances of heart disorders. Groundnut Oil is rch in Vitamin E, Monounsaturated
Fatty Acids (MUFA) and Polyunsaturated Fatty Acids (PUFA) which lower the risk
of heart disease. Moreover, groundnut oil is cholesterol free. The unsaturated
fats available in it help in lowering LDL cholesterol and increase HDL
Cholesterol adding to the cardiovascular health.
- Antioxidant
Properties
Cold Pressed Groundnut oil is rich in
Phytophenols and Vitamin E which act as Antioxidants reducing the oxidative
stress in the body. The antioxidants have anti-ageing
properties and prevent the body from the risk degenerative diseases like
Alzheimer’s disease. Also, the anti-inflammatory properties of the antioxidants
supports joint health and provides relief in certain types of Arthritis like-
Rheumatoid arthritis.
- Diabetes Control
Groundnut oil is considered good for diabetics.
The unsaturated fats present in it improve Insulin sensitivity in the body.
Also, Oleic Acid present in Peanut oil promotes Insulin production and help
control type 2 Diabetes.
- Skin and Hair
Health
Groundnut oil has several benefits for
skin and hair as well. It helps in moisturization, reduces
the signs of ageing, helps in the treatment of Scalp Psoriasis and
strengthens hair. Topical massage with groundnut oil helps in blood circulation
in the body and improves the skin health.
