Of all the treats available,
chocolate is one of the most craved foods in the world. The first solid
chocolate bar, made from cocoa butter, cocoa powder and sugar, was introduced
by the British chocolate company J.S. Fry & Sons in 1847, but the history
of chocolate goes back at least 4,000 years.1
Pre-Olmec cultures in Mexico
produced chocolate as early as 1900 B.C. Originally, it was consumed as a
bitter beverage. The cacao beans were fermented, roasted, and then ground into
a paste that was mixed with water and spices like chili peppers and vanilla,
sweetened with honey.
Throughout its history, chocolate —
"the food of the Gods" — has remained a symbol of luxury, wealth, and
power. During the 14th century, the Aztecs and Maya even used cacao beans as
currency. Research has also revealed chocolate has some rather impressive
health benefits, provided you're willing to give up the now-familiar sweetness
of modern day milk chocolate.
The Olmecs, Maya, and Aztecs valued
cacao for its mood enhancing and aphrodisiac properties, and it was typically
reserved for the ruling class. In the 17th century, cocoa and chocolate were
considered potential medicine, and historical documents in Europe reveal they
were used to treat angina and heart pain.2
Not All Chocolate Is Created Equal
Raw cacao is actually quite
bitter, not sweet, due to the nearly 400 polyphenols that are
present. When we're referring to the health benefits of chocolate, this is the chocolate we're referring to.
Americans consume an estimated 12 pounds of chocolate per capita each year.3
Unfortunately, the vast majority of
that is in the form of milk chocolate candy, which contains very minute amounts
of healthy cacao, and loads of sugar. The milk added to milk chocolate can also interfere with
your body's ability to absorb the beneficial antioxidants (polyphenols) in the
chocolate.
Chocolate Terminology
To get off on the right foot, it may
be helpful to understand the distinction between cacao, cocoa, and chocolate:4
·
Cacao: Refers to the plant, a small evergreen tree of the
species Theobroma cacao, and its dried seeds, also known as cacao beans or
cocoa beans, prior to processing.
If you're after health benefits, raw cacao nibs are what
you're looking for. Ideally, buy them whole and grind them yourself (a coffee
grinder can be used for this) when using it in recipes.
Alternatively, you can eat them whole, just like you'd eat
conventional chocolate chips. A healthy amount would probably be around ½ to 1
ounce per day. I personally grind 1 tablespoon of raw cacao nibs twice a day
and put them into my smoothies.
·
Cocoa: Refers to the roasted cacao, ground into a powder from which
most of the fat has been removed.
·
Cocoa
butter: The fat component of the cacao
seed.
·
Chocolate: The solid food or candy made from a preparation of
roasted cacao seeds; if the cacao seeds are not roasted, then you have
"raw chocolate."
When selecting chocolate, look for higher cacao and lower
sugar content. In general, the darker the chocolate, the higher the cacao
content.
However, since cacao is bitter, the higher the percentage
cacao, the more bitter it is (the polyphenols are what make the chocolate
bitter, so manufacturers often remove them. But, it's those polyphenols that
are responsible for many of chocolate's health benefits).
To counteract the bitterness, most chocolate is sweetened,
so it's a matter of balancing nutritional benefit with palatability. For health
benefits, choose chocolate with a cacao percentage of about 70 or higher.
·
"White
chocolate" contains no cocoa at all; it's
just a health-zapping mix of pasteurized milk and sugar.
Chocolate and Human Health
A 2013 paper12 in the Netherlands Journal of
Medicine also reviews the many health benefits of cacao, noting that many
consider it a "complete food," as it contains:
·
Healthy fats
·
Antioxidants
·
Nitrogenous compounds, including
proteins, methylxanthines theobromine, and caffeine (central nervous system
stimulants, diuretics, and smooth muscle relaxants. Theobromine is the
ingredient that can cause heartburn in some individuals; on the other hand, it
also inhibits persistent cough by reducing vagus nerve activity13)
·
Valeric acid (which acts as a stress
reducer despite the presence of stimulants)
The following table highlights the
wide range of positive health benefits science suggests are conferred by the
cocoa bean.14,15,16
