Chocolate: The Latest Antioxidant
Since well before its introduction to western consumers in the sixteenth
century, cocoa and its most popular derivative chocolate have long been
used as therapeutic and medicinal remedies. Whether it was Aztec shamans
using cocoa as a divine potion, or later aficionados praising its
heart-strengthening and restorative qualities, cocoa and chocolate have
always been regarded as considerably more than simple snacks or drinks.
Perhaps the world's first 'functional food' or nutraceutical, the
twentieth century has seen the development of some widespread myths and
misunderstandings surrounding both cocoa and chocolate. Chocolate is
said to trigger migraines or tension-type headaches. In fact it does
not. Recent research shows headaches and chocolate consumption to be
unrelated. Neither does chocolate cause tooth decay, it actually clears
the mouth relatively quickly and studies show that some of the compounds
in chocolate may help prevent bacterial attacks on tooth enamel. There
are those who claim that chocolate is addictive, either because of its
caffeine content, or because of a combination of some of the other
compounds it contains. This is incorrect. The levels of caffeine or
other pharmacologically active constituents of chocolate, such as
theobromine, are not sufficient to satisfy a chocolate craving. People
crave chocolate for a very simple reason — its taste. There is no link
between acne and chocolate. It does not raise cholesterol levels as part
of a balanced diet; on the contrary, dark chocolate is almost
cholesterol free and although some consider it a commonly allergenic
food, one recent study found that only one in 500 of those who
considered themselves allergic to chocolate actually were. It appears
that far from being the cause of any addiction, decay or dietary
deficiency, the only thing chocolate is guilty of is being a delicious
all round sensory experience.
Anti-oxidative Properties Of Chocolate
The
good news does not stop there. Research into the nutritional and chemical
properties of chocolate has intensified over the last two or three years
in the wake of several studies that suggest that as well as its sensory
impact, chocolate can actually have a positive impact on nutrition and
health. A report from Harvard University found that people who eat sweets,
including chocolate, appear to live almost a year longer, on average, than
those who do not.
Ongoing studies into heart disease, which linked the consumption of
certain teas, red wine and fruit and vegetables with a reduced risk of
cardiovascular problems, now associate this reduction with the
polyphenol content of those products. Polyphenols are an anti-oxidative
group of phytochemicals, that is, an antioxidant variety of the
naturally occurring chemicals found in all plants, including cocoa. The
presence of polyphenols in chocolate is well documented, but studies had
previously focused on the role they played in flavour and colour
development. With all the positive benefits being associated with
polyphenols in other foods, the chocolate industry re-examined these
compounds in order to investigate the possible health benefits that they
may present for cocoa and chocolate consumers. It has since been
confirmed that cocoa beans not only contain very impressive quantities
of natural polyphenolic antioxidants but, perhaps more importantly, the
preliminary findings indicate that such levels may carry with them real,
substantive health benefits for chocolate lovers.
The Health Benefits
Antioxidants like polyphenols combat free-radicals which are normally
produced in our bodies. In doing so they provide benefits to virtually
all the major systems of the body, in particular the cardiovascular
system, the immune system, neurons in the brain, protection against
cancers and the slowing of some steps in the aging process. While the
antioxidant properties of fruits and vegetables are well known, dark
chocolate, for example, has been found to contain twice the antioxidant
levels of prunes, which have one of the highest levels among fruits.
Studies from the University of California in the USA and the University
of Buenos Aires in Argentina indicate that the high levels of
polyphenols in cocoa and chocolate may have a favourable impact on the
risk factors associated with heart disease. They confirmed that the
amount of antioxidants in the blood stream increased within two hours of
chocolate consumption by healthy men and women and that the heart may
benefit due to a reduction in the reactivity of blood platelets. The
reactivity of blood platelets promotes the phenomenon of blood clotting
and many doctors recommend that patients at risk of heart disease take
aspirin to mildly inhibit this clotting. These latest findings suggest
that the antioxidant polyphenols in cocoa and chocolate can have a
similar beneficial effect and inhibit the capacity of blood clotting,
thereby reducing the risk of cardiovascular disease. The key elements of
oxidation in the blood are the so-called free radicals, which scientists
have linked to ageing, certain degenerative diseases of the eye and
nervous system and cardiovascular disease. One of the most effective
antioxidant varieties of polyphenols are flavonoids. Studies have
indicated that the flavonoids in cocoa have a significant inhibiting
effect on carcinogenesis, that is, the cancer forming process, through
their antioxidant and free radical combating properties. In Japan, there
are even two patents for cocoa extracts that claim to prevent the
development of cancer and that can be used as a nutritional supplement
or as an ingredient in a functional food. Also in Japan, a company
recently introduced a chocolate bar with an elevated flavonoid content,
the packaging of which states that it retards the development of cancer,
as well as cardiovascular disease and diabetes.
It has been known for some time that cocoa and polyphenol extracts of
cocoa can prevent dental caries. It is believed that the polyphenol
inactivates the enzyme responsible for catalysing the production of
poly-saccharoses from sugar — the binding agent that attaches the dental
plaque to the teeth.
Infectious And Auto-immune Diseases
The immune system protects against infection caused by invasion of
pathogenic cells, such as bacteria, moulds, viruses and parasites and is
also active in removing muted cells that can initiate cancer. The immune
system demands a well-balanced interaction between various types of
cells produced by the lymph glands. These cells possess a permeable cell
membrane, which contains a high content of poly-unsaturated fatty acids.
Consequently, it is very sensitive to lipid peroxidation. When the
immune system is out of balance it can react excessively, causing over
production of oxygen radicals and peroxides that can cause acute
inflammations leading to auto-immune diseases such as rheumatic
arthritis and stomach ulcers. It has been shown that antioxidants may
play an important regulating role in the functioning of the immune
system and preventing infection and auto-immune diseases.
Free radicals are generally believed to play an important role in the
ageing of cells. Over time, the anti-oxidative system in the cell
becomes less efficient, allowing the radicals more opportunity to do
their destructive work. Extensive research has found that it may be
possible to extend the life expectancy of a healthy human being by 5-10
years by adhering to an active life-style and a well balanced diet, high
in antioxidants such as the polyphenols found in chocolate.
Conclusion
Contrary to well entrenched beliefs, far from having negative health
implications, chocolate can actually be considered a beneficial element
of a well-balanced and nutritious diet, that is, one containing a wide
variety of foods and one where total caloric consumption is in balance
with caloric expenditure. And it doesn't taste too bad either.
