Ibuprofen or Tart Cherries?
A collaborative research article by Dr. Jeff Tirsch,
D.C.
Despite the dangers of oral medications, many patients with painful
conditions such as Fibromyalgia, Arthritis and Gout still take drugs
such as aspirin and ibuprofen are called non-steroidal anti-inflammatory
drugs (NSAIDs) for their pain. As you may know, these medications work
by inhibiting two enzymes, cyclooxygenase I and II (popularly known as
COX 1 and COX 2), which are produced by the body as a response to pain.
NSAIDs prevent chemical messages from binding to cyclooxygenase. The
normal messages are not delivered, so the body does not feel the pain
and doesn't become inflamed (1). Unfortunately, many patients take pain
medication daily that can cause numerous side effects, including upset
stomachs, vomiting, kidney damage and, possibly, ulcers. This is because
NSAIDs inhibit both COX 1 and COX 2, but the COX 1 enzyme is also
important for maintaining normal cell function within several organs
(2).
Tart cherries contain flavonoid compounds that function in the same
manner as NSAIDs and can inhibit both COX enzymes. However, research
shows that flavonoids can also protect against stomach damage, unlike
their NSAID counterparts (3). It is suspected that the high levels of
antioxidants found in cherries, particularly melatonin, provide a
protective function and prevent unwanted symptoms. This makes
concentrated cherry products superior to over-the-counter pain relief
because cherries block pain in the same manner and reduce potential
side-effects (4).
But that is not all! New studies at Michigan State University (MSU),
which were recently published in Cancer Letters, suggest that tart
cherries may reduce the risk of colon cancer because of the anthocyanins
and cyanidin contained in the cherry. Dr. Mauraleedharan Nair and Dr.
Leslie Bourquin along with several graduate students worked on
experiments that are part of ongoing research on the components of tart
cherries.
"Based on previous observations that tart cherries can inhibit the Cox
enzymes, we conducted experiments to test the potential of tart cherry
anthocyanins to inhibit intestinal tumor development in mice," says Dr.
Bourquin, an associate professor in food science at MSU. The laboratory
mice can very quickly produce the same type of tumors as humans. Mice
consuming the tart cherry anthocyanins had significantly fewer and
smaller cecal adenomas (colon tumors) than the mice consuming the
control diet.
Pain is often a big factor in the quality of life and Dr. Nair thinks
that the pain relieving power of tart cherry anthocyanins may have
direct applications in cancer. While the research on tart cherry
anthocyanins at MSU is ongoing, Dr. Nair also has teamed up with
researchers at other universities to study the pain relief of tart
cherries (especially as related to cancer). A project at Johns Hopkins
University in which Dr. Nair collaborated with Dr. S. Raja studied tart
cherry anthocyanins in relation to chronic pain. The current interest in
the health benefits of whole foods, including cherries, will continue,
according to Dr. Bourquin. "It will eventually be possible to identify
the compounds in dietary ingredients that can reduce chronic disease. We
will continue to move in that direction.
"Recently published research conducted at Michigan State University (5)
investigated a range of fruits and berries for the level and activity of
anthocyanins found in each. Researchers analyzed the ability of the
fruits to inhibit cyclooxygenase and act as antioxidants to destroy free
radicals. Researchers discovered that the antioxidant activity of
anthocyanins from cherries was superior to vitamin E at a test
concentration of 125 g/ml. The COX inhibitory activities of anthocyanins
from cherries were comparable to those of ibuprofen and naproxen at 10 M
concentrations. Anthocyanins 1 and 2 are present in both cherries and
raspberries. The yields of pure anthocyanins 1 and 2 in 100 g in
cherries and raspberries were the highest of the fruits tested at 26.5
and 24 mg, respectively. Fresh blackberries and strawberries contained
only anthocyanin 2 at a total level of 22.5 and 18.2 mg/100 g,
respectively; whereas anthocyanins 1 and 2 were not found in bilberries,
blueberries, cranberries or elderberries. According to Dr. Muraleedharan
Nair, a professor in the Department of Horticulture at Michigan State
University and with the National Food Safety and Toxicology Center at
MSU in East Lansing, Michigan, twenty cherries provide 25 milligrams of
anthocyanins.
According to the article "Fresh Cherries May Help Arthritis Sufferers,”
published in put out by the USDA (6), Results of a preliminary study by
ARS scientists and their university colleagues suggest that some natural
compounds in plump, juicy Bing cherries may reduce painful arthritic
inflammation. Eating cherries may also help lessen the severity of other
inflammatory conditions, such as cardiovascular disease or cancer. 45
fresh, pitted Bing cherries for breakfast. Ten healthy women, aged 22 to
40, agreed to eat 45 fresh, pitted Bing Cherries.
While Bing Cherries were the focus of this study, research conducted at
Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts
University in Boston and Brunswick Laboratory in Wareham, Massachusetts
demonstrates that Montmorency dried tart cherries have a score of 6,800
ORAC (oxygen radical absorption capacity) as compared to only 670 for
sweet or black cherries (7). The ORAC test accurately quantifies the
antioxidant capacities of foods by taking into account the fact that
most natural products are a complex mix of phytochemicals of which many
are antioxidants.In addition, tart cherries were found to contain
significant levels of antioxidant activities against peroxyl radicals,
peroxylnitrite, hydroxyl radicals (known as NORAC and HORAC). Just like
the superoxide anions, these human-cell killing species are known to be
involved in the pathogenesis of aging and neurodegenerative diseases.
Brunswick Labs only recently developed assays to measure NORAC and
HORAC. Few food products have been measured for NORAC and HORAC. They
found that cherries contain a class of compounds that act like super
oxide dismutase (SOD), which is a powerful enzyme and cellular
antioxidant. Testing showed that one serving of canned tart cherries is
equivalent to 1.41 grams of aspirin, a higher value than one serving of
tart cherry juice, indicating that the cherry in its whole form may be
the most potent.
Tart cherries have shown great potential in treating pain and
inflammation, gout, fibromyalgia, heart disease, arthritis, and possibly
even cancer. A great example of a whole tart cherry supplement is
TheraCherry, made from whole Montmorency tart cherries. Each capsule of
TheraCherry contains the equivalent of about 20 tart cherries and you
can purchase TheraCherry here.
