Cis-fats and Type 2 Diabetes
Cis-fats may prove to be a vital part of finding a diabetes
cure for Type 2 through diet. When you read about fats you will
come across many different terms. You may find them very
baffling, and to understand them fully does actually need a
knowledge of biochemistry at degree level. You don't need that
depth of knowledge though to get a grasp is what is important
in your diabetes diet. You don't go into a shop and ask for
mono-unsaturated fatty acids, but you do need to know what
types of fats or oils contain them.
The biochemical name for fats is triglycerides. This is
because they are made up of three fatty acid molecules attached
to a glycerol molecule. Fatty acids are formed by long chains
of carbon atoms, together with carbon and hydrogen. Each carbon
atom has four possible links to other atoms. Two attach it to
the carbon atoms on each side in the chain and the other two
are usually attached to hydrogen atoms. Sometimes, instead of a
single link between carbon atoms there is a double link (double
bond), so there is only one link to a hydrogen atom.
Fats with only single bonds between the carbon atoms and the
maximum number of hydrogen atoms are called saturated fats. If
there is just one double bond the are called mono-unsaturated
fatty acids. If there is more than one double bond they are
called poly-unsaturated. The double bonds of fatty acids may
twist the chain in two different directions, making the carbon
chain straight or more curly. If a double bond tends to keep
the chain straight it is known as a trans bond. If it tends to
kink the chain, it is known as a cis bond.
It is possible to force extra hydrogen atoms into the double
bond links, making them single bonds and taking on extra
hydrogen atoms in the carbon chain. This process is called
hydrogenation. By and large, it is mono- or polyunsaturated
cis-fats that occur naturally in oils of various types.
Trans-fats are widely made and used in the processing of foods
because the addition of the hydrogen atoms in straighter
molecule chains makes the fats solid rather than liquid, and
because it was believed that these fats were less unhealthy
than saturated fats. In fact, the very opposite may be the
case, since trans-fats are now known to damage cell membranes.
Some people believe that the toxic effects of trans-fats may
actually be the cause of Type 2 diabetes, and that cis-fats in
a diabetic diet may offer the hope of a diabetes cure
There is increasing evidence of the importance of cis
mono-unsaturated fatty acids. Most studies have found that
these oils, as part of a diabetes diet in which fat provides up
to 30% of the calories helps control of blood glucose and
improves the cholesterol profile, providing protection against
coronary heart disease. This approach may improve blood
pressure and a number of other risk factors too.
The oils which contain the highest amounts of healthy fats
are flax (linseed) oil, hemp oil and fish oils. Olive oil is
also good. Margarines contain large quantities of trans-fats,
as do many "junk" foods", and these should be avoided whether
or not you have diabetes. Dr Tony Woolfson MB BS DM
