There is very little literature on possible
ways to strengthen the BBB. Recently an essay
on this subject was posted on a web site
(http://spider.lloyd.com/~tstout/articles)
by T. Stout. Much of the information in this
section is taken from this excellent contribution.
Experiments with animals have shown that
there are three related chemicals, anthocyanosides,
proanthocyanidins and procyanidolic oligomers,
which strengthen the BBB (Robert et al.,
1977; Detre et al., 1986). These chemicals
are found in blueberries, cherries, black
berries, grapes and the bark and needles
of certain pine trees. They are currently
available as encapsulated supplements called
bilberry, grape seed extract and pycnogenol.
These supplements and/or substantial quantities
of the above fruits should be ingested daily
to help strengthen the BBB.
The anthocyanosides and proanthocyanidins
act as very powerful anti-oxidants, block
enzyme actions and bind with the BBB and
it is these properties which likely result
in their beneficial effect on the BBB (see
Stout essay for details). Other supplements
which are anti-oxidants (much less powerful)
include vitamin A (cod liver oil), vitamin
C (with bioflavonoids) and vitamin E. These,
along with vitamin B complex and vitamin
D, should be taken daily. Calcium and magnesium
supplements are also essential and have been
shown to beneficially affect MS progression
(Goldberg et al., 1986).
As described earlier, micro-emboli,
formed
due to high saturated fat intake, also
damage
the BBB. As a complementary treatment
to
the reduced intake of saturated fats,
consumption
of polyunsaturated fats should be increased.
Such fats aid in the desegregation
of platelets
and are important for cell growth and
reducing
inflammation. These fats include unrefined
safflower, sunflower and flax oil as
well
as encapsulated evening primrose oil
and
borage oil. It was recently scientifically
shown that gamma-linolenic acid, the
key
ingredient of evening primrose oil
and borage
oil, greatly reduced arthritis attacks
(Zurier
et al., 1996). Fish also contain valuable
polyunsaturated fats (omega 3 EFA)
and should
be eaten at least two or three times
a week.
Fish oil (e.g. salmon oil) is also
available
in capsules. Notably fish oil has been
found
to be very beneficial in controlling
another
autoimmune disorder, Crohn's disease
(Belluzzi
et al., 1996). The interested reader
is referred
to the comprehensive book by Erasmus
(1993)
which provides detailed information
on the
harmful effects of some fats and the
beneficial
effects of others.
