A good diet for dementia is not the
same thing as a targeted one. This week there was much news about
green tea being good for Alzheimer's disease, unfortunately these
stories are more newspaper hype than reality. With the brain robbing
illnesses increasing worldwide many are seeking ways to fight back.
Researchers have shown that a targeted diet for dementia is better
than a good diet.
Green tea? Why this tea will not help Alzheimer's disease
Green tea is
consumed worldwide and particularly in Asian countries, the substance
in green tea called Egcg is widely studied and many believe that it
can help reverse Alzheimer's disease but there is a huge problem. The
egcg does not cross the blood brain barrier, in other words it cannot
reach the brain cells that are in need of help. Why do the green tea
studies work in a laboratory? Researchers isolate the Alzheimer's
cells and put it in a dish, they then add egcg isolated from green
tea. When they see a change(or reversal) in the Alzheimer's cells
they conclude that green tea can help fight the illness. This does
not work when it comes to the human brain, this may work in a dish
but the human brain has a barrier and it is very selective about what
it allows to cross that barrier. Green tea's egcg does not cross the
brain blood barrier. Green tea may be a part of a good menu but it
will not help in the diet for dementia
Researchers
in Italy showed that green tea does not pass into the brain cells,
the abstract from the study is below
Following acute ingestion of green tea
by six human subjects, HPLC-MS2 analysis revealed that flavan-3-ol
methyl, glucuronide and sulfate metabolites appeared in the
bloodstream but did not pass through the blood-cerebrospinal fluid
barrier.
The Italian study above showed that
green tea did not pass through the brain barrier but was in the
bloodstream, green tea may be good for the body but does not help the
brain directly. We have researched this illness in over 5 countries
and we can tell you that much can be done to reverse the illness but
the diet for dementia must be targeted and based on good science.
Green may be good for you but so far it does not help Alzheimer's
disease. What can help? Nutrients that pass the Brain Blood Barrier can reverse the illness
