Myth: Palm Oil is unhealthy oil full of saturated fats
that promotes heart disease.
Facts: Two
Oils Oil Palm fruit produces two types of oil. Palm Oil (PO) from the
flesh of the fruit and Palm Kernel Oil (PKO) from the seed kernel - in the ratio
of 4 to 1. PO is around 40-50% saturated, whilst PKO is around 75-80% saturated.
Saturated fat is defined as solid at room temperature and whose fatty acid chain
cannot incorporate additional hydrogen atom.

No all Saturated Fats are bad for Cholesterol The general
hypothesis that all forms of saturated fat are bad for health is simply wrong,
because many past studies concluding saturated fat promotes heart disease were
actually done using hydrogenated polyunsaturated fats (associated with
trans-fat). Studies have shown that there is no relation between
saturated fat intake and risk of coronary heart disease.
Saturated fats are needed for many bodily processes, such as the
following:
- They are needed to maintain cell membranes, which are at least 50% saturated
fat, giving them stiffness and integrity.
- They keep our bones strong and healthy by allowing calcium to be
incorporated into them. This requires >50% of dietary fat to be saturated.
- They enhance the immune system
- They aid in utilization of essential fatty acids, and help to retain omega
3's in the tissues Short & medium chain fatty acids have anti-microbial
properties and protect against harmful micro-organisms in the digestive tract
Studies have shown that not all saturated fats alleviate cholesterol, and not
all cholesterol promotes heart disease. It's the low-density-lipoprotein (bad
cholesterol) that poses health threats. High-density-lipoprotein (good
cholesterol) serves as transporter that removes cholesterol from vulnerable
areas, taking it back to the liver for recycling & disposal.
Palm oil's saturated fats have been shown to have neutral to favorable impact
on cholesterol. Palm Oil's unsaturated fats comprise of largely monounsaturated
fats that tend to lower bad cholesterol without also lowering the good
cholesterol (unlike polyunsaturated fats). To top that off, palm oil is rich
source of nutrients such as beta-carotene, alpha-carotene, vitamin E
tocotrienols, Iycopene and other carotenoids which acts as super-antioxidant
that helps reduce cancer risks and fight free radicals in the body. Palm oil
also contains linoleic acid, which is an essential fatty acid that the body
cannot produce.
The best part is that palm oil has similar functional properties of
hydrogenated oils without the associated health threats. Other liquid oils are
hydrogenated into solid fats to increase stability, shelf live, and melting
points for broader food industry use. The hydrogenation process alters the fat
molecules configuration from a state known as 'cis' form to a 'trans' form.
Similar molecular transformation also happens when deep-frying with oils that
has low heat stability. Trans-fat (named after its configuration) when consumed
takes around 3 times longer to metabolize in the body, increases bad
cholesterol, and reduces good cholesterol. Trans-fat is dangerous and more
harmful than saturated fats. Palm oil is trans-free, cholesterol-free, and has
high oxidative stability. |
