Butter
is one of the most highly concentrated forms of fluid milk containing
protein, calcium and phosphorus
(about 12%) and fat-soluble vitamins A D & E.
MARGARINE
CHARACTERISTICS
When
margarine first appeared on the market it looked and tasted like lard.
The gurus rethought the process and using sophisticated techniques
developed a product that smelled and tasted like butter. Butter
producers, believe it or not, went back to the drawing board and today
most butter contains colour additives to compete with the yellowness of
margarine.
While
margarine is often advertised as being derived from polyunsaturated
oils, what you should know is that the oil is changed to margarine by a
method called hydrogenation – saturating with hydrogen.
Some
margarines do contain small amounts of liquid polyunsaturated oil added
to a hydrogenated base, but the bulk of the fat must of necessity be
saturated. Otherwise margarine would be liquid like any polyunsaturated
oil. Once a vegetable fat is hydrogenated, a new fat has been created.
Margarine
is a perfect example of a fabricated food, the earliest non-dairy
substitute. There
has been vast research into the production of margarines.

Here
are some explanations of terms that may help you when we discuss
cholesterol. It is very important to understand that there are 2
kinds of cholesterol.
Fats
and oils are mixtures of fatty acids. Each fat or oil is
designated ‘saturated’ ‘monounsaturated’ or
‘polyunsaturated’ depending on which oil predominates.
SATURATED
FATTY ACIDS
have all the hydrogen the carbon atoms can hold. Saturated fats
are usually solid at room temperature. They don’t combine easily with
oxygen and turn rancid. Saturated fatty acid raises cholesterol, which
in turn raises the risk of coronary heart diseases and strokes.
MONOUNSATURATED
FATTY ACIDS are
liquid at room temperature. They have only one unsaturated bond.
Salad dressing containing olive oil turns cloudy when refrigerated but
is clear at room temperature. MFA seem to lower total cholesterol
when substituted for saturated fat.
POLYUNSATURATED
FATTY ACIDS
have more than one unsaturated bond. Polyunsaturated oils help lower
cholesterol when substituted for saturated fats. In
addition dietary cholesterol found in animal fats raises total blood
cholesterol and LDL (Bad Cholesterol)
WHAT
ARE TRANS FATTY ACIDS?
A
fatty acid molecule is connected to hydrogen. People eat them in
the form of meat and dairy products.
HOW
DOES HYDROGENATION CREATE TRANS FATTY ACIDS?
To
help foods stay fresh on the shelf or to get a solid fat such as
margarine, food manufacturers hydrogenate polyunsaturated oils.
Hydrogenate means to add Hydrogen.
HOW
ARE TRANS FATTY ACIDS HARMFUL?
In
clinical studies, trans fatty acids or hydrogenated acids tend to raise
total blood cholesterol levels and LDL (bad cholesterol) and lower HDL
(good cholesterol).
BUTTER
The problem with
butter is that it contains two cholesterol raising agents, dietary
cholesterol and saturated fat.
Dietary
cholesterol is found only in animal products. There is none in
plant-based food.
Different
people have different cholesterol tolerances. A doctor should be
consulted and relevant tests undergone to determine personal cholesterol
levels and the amount of future intake.
It
is important to know that cholesterol is needed to maintain intestinal
health and is also needed for brain and nervous system development of
the young. Human breast milk is extremely high in saturated fat and
cholesterol.
Cholesterol
aside, butter’s biggest trouble is its saturated fat content.
These are solid at room temperature and are found largely in red meat
and ‘high dairy ‘products. In
excess it raises the LDL.
A healthy moderate range of saturated
fats is 10-15 grams.
Moderation
in everything!
BUTTER
is a rich source of easily absorbed vitamin A. It also contains
all the other fat-soluble vitamins E, K and D. It is rich in trace
minerals especially selenium, a powerful antioxidant. It supplies iodine
and vitamin A needed by the thyroid gland. Butter has appreciable
amounts of BUTYRIC ACID used by the colon as an energy source. It
is also a known anti-carcinogen.
MARGARINE
is by no means void of artery clogging fat. This may come as a big
surprise to some. Here the controversy lies with its levels of
trans fat – largely a man made fat. These are formed when
hydrogen is added to vegetable oil making it more solid and less likely
to spoil.
What
is more, trans fats may make our blood platelets stickier. A
blood platelet is a minute, colourless disc shaped corpuscle. Large
numbers are found in the blood of mammals and aid coagulation.
The
more solid the margarine is at room temperature, the more trans fat it
contains. As a
rule, the softer the margarine product, the fewer trans fatty acids it
contains.
The
anti margarine lobby attack the way it is made. All margarines are made
from assorted vegetable oils that have been heated to extremely high
temperatures. This causes the oils to become rancid. After that a
nickel catalyst is added, along with hydrogen atoms to solidify it.
Nickel is a toxic heavy metal. Finally deodorants and colouring
are added to remove the margarine's smell (from the rancid oils) and
greyness.
