Question:: The British are investigating the possible connection
between curcumin and treatment for Alzheimerís disease. Anything to
this? Answer::
The Brits arenít alone in this effort. Researchers here in the United
States have been pursuing clues to the effects of curcumin, a
compound found in the spice turmeric that is responsible for the
yellow color of Indian curry and American mustard. Studies show that
elderly villagers in India appear to have the lowest rate of
Alzheimerís disease in the world. Researchers speculate that
curcumin, which has powerful antioxidant and anti-inflammatory
properties might play a role, because Indians eat turmeric with
almost every meal.
In a recent study at the University of California at Los Angeles,
scientists fed curcumin to rats prone to accumulate beta-amyloid
plaque in their brains ñ the abnormality associated with Alzheimerís
disease in humans. Curcumin blocked the accumulation of beta-amaloid
plaque and also appeared to reduce inflammation related to
Alzheimerís disease in neurologic tissue. The rats fed curcumin also
performed better on memory tests than rats on normal diets.
The UCLA study isnít the only one that suggests that curcumin might
prove helpful for treatment and prevention of Alzheimerís.
Researchers at the University of Illinois have also found that it
helps prevent plaque formation. And preliminary studies at Vanderbilt
University suggest that curcumin may block the progression of
multiple sclerosis. Mice with an MS-like illness showed little or no
signs of disease after being injected with curcumin, while their
untreated counter parts went on to severe paralysis. New research
from Japan also suggests that turmeric may help prevent colitis, an
inflammation of the colon.
My friend Paul Schulick of New Chapter, Inc., who brought me up to
speed on the latest curcumin research, tells me that only low dose
curcumin reduced plaque in the Alzheimerís disease studies. This is
good news since it suggests that curcumin is most effective at doses
well below pharmaceutical strength. Schulick also emphasizes that
turmeric contains many other compounds besides curcumin and points
out that people in India consume the whole spice not an isolated
element. Turmeric appears to have significant anti-inflammatory and
cancer-protective effects as well, so I think it is good to find ways
to include it in our diets.
