Coffee and Tea and Cocoa…Oh My!
Elizabeth Pavka, PhD, LD/N, sorts through
the research about coffee and tea so you can feel even cozier
with the beverage of your choice in hand. |
Ah, a cold night, a warm fire, and a hot
cup of coffee or tea: the definition of coziness. But, how do
you choose what to drink? Taste? Price? Health? Research is beginning
to document that coffee, tea and even cocoa have health benefits,
although there is some conflicting information due to the newness
of the research. That said, let’s explore some of the upsides
and downsides of each choice, so you can settle by the fire with
the perfect cup for you.
TEA FACTS:
The botanical name for tea is Camellia sinensis.
People have been drinking hot tea beverages for over 4,700 years.
Tea contains over 4,000 chemical compounds, encompassing a large
class of antioxidants known as catechins, which includes a smaller
group called polyphenols, and—at least until new research
comes in—the active ingredient currently being studied is
epigallocatechin gallate (EGCG).
A cup of green tea contains between 15 and 50 milligrams of caffeine,
depending on the length of time the bag steeps.
IS THERE AN UPSIDE TO
TEA CONSUMPTION?
In Traditional Chinese Medicine, green tea is classified as a
leading health-giving substance. Active ingredients include catechin
and L-theanine. Catechin acts as an antioxidant molecule that
scavenges and destroys free radicals, illness-producing molecules
in the blood and brain. This essential process helps explain how
green tea can function in so many ways in our body, i.e. fight
cancer, decrease high blood pressure, and diminish inflammatory
bowel disease, diabetes, liver disease, and neurodegenerative
diseases like Alzheimer’s and Parkinson’s. All of
these health conditions are caused, in part, by excessive free-radical
production in the body (1).
The amino acid L-theanine, found almost exclusively in the tea
plant, actively alters the attention networks of the brain. According
to results of human trials announced in September 2007, John Foxe,
Ph.D., professor of neuroscience, biology and psychology at City
College of the City University of New York, found that theanine
is absorbed by the small intestine, enters the blood stream and
crosses the blood-brain barrier where it affects the brain’s
neurotransmitters and increases alpha brain-wave activity. The
result is a calmer, yet more alert, state of mind (2).
IS THERE A DOWNSIDE TO TEA CONSUMPTION?
All tea leaves contain fluoride, and more mature leaves contain
as much as 10-20 times the levels of fluoride as in the young
leaves of the same plant (3). According to the Canadian organization
Parents of Fluoride Poisoned Children, the fluoride content in
mature green tea leaves is much higher than the maximum contaminant
level allowed (4).
COFFEE FACTS:
Coffee, botanical name Coffea arabica, has been consumed as far
back as the tenth century, when Ethiopian highlanders first cultivated
the coffee bean.
Coffee contains hundreds of compounds, including substantial amounts
of magnesium, potassium, vitamin B-3, lignans, and a class of
antioxidants called polyphenols.
One eight-ounce cup of coffee contains approximately 85 milligrams
of caffeine, depending on how much coffee is used per cup of water.
In the past two decades, there have been more than 19,000 studies
conducted on coffee.
According to the U.S. Department of Agriculture, Americans, on
average, drink 1.64 cups of coffee a day.
WHAT IS THE UPSIDE TO COFFEE CONSUMPTION?
According to Dr. Andrew Weil, the most clear-cut findings about
the benefits of coffee come from a 20-year study that followed
approximately 84,000 women and 44,000 men. Published in the May
2, 2006, issue of Circulation, the study concluded that drinking
coffee isn’t harmful to cardiovascular health and may even
be somewhat beneficial (5). Dr. James Coughlin, a toxicology and
safety consultant, says that some scientific evidence suggests
that one cup of coffee can decrease the risk of Parkinson’s
and Alzheimer’s diseases, kidney stones, gallstones, depression
and even suicide by 50 percent. This may result from the antioxidant
properties of the polyphenols, although firm, repeatable research
has not yet borne that out (6).
It’s also reported that coffee may reduce the risk of type
2 diabetes. This finding is based on a review of nine studies
published in the July 6, 2005, issue of the Journal of the American
Medical Association, but it conflicts with earlier evidence suggesting
that coffee can reduce insulin sensitivity, which would increase
the risk of diabetes. To confuse matters further, a study published
in the February, 2006, issue of Diabetes Care found that decaf
lowers the risk of diabetes, suggesting that something other than
caffeine may be responsible for any protection coffee provides.
WHAT IS THE DOWNSIDE TO COFFEE CONSUMPTION?
Certainly there is a downside to drinking coffee: well-documented
side effects include increased anxiety, insomnia, tremor and irregular
heartbeat. Coffee can also irritate the digestive system, bladder
and prostate.
In my work as a nutritionist, I’ve heard quite a few older
women tell me they only had hot flashes on days when they drank
coffee. One client couldn’t believe me when I suggested
that connection. Several months later, I met her downtown, where
she came up to me and confirmed that her hot flashes disappeared
when she stopped drinking coffee.
THE VERDICT - WHAT DO YOU THINK?
Whether you decide to drink coffee or green tea, cocoa or herbal
teas, drink the best quality, preferably organically harvested
and Fair Trade Certified, you can afford. By purchasing quality
beverages, we can improve the health of our bodies, our soil,
our water, our air, and our future. And, tune in to your own body.
You know your body better than anyone else. The way coffee or
tea affects you is your best guide to whether or not you should
be drinking it and, if so, how much. After you’re tuned
in, when you curl up by the fire with a warm cup of whatever,
you can truly enjoy the the warmth, closeness and the coziness
of it all!

Bean Basics
If coffee’s your thing, Kevin
Price has you covered with these great java tips.
What should I look for when purchasing coffee?
When purchasing coffee, you want to purchase the freshest coffee
available to ensure the richest flavor. Generally, you can tell
if the beans are freshly roasted just by looking at them. Darker
roasted coffee beans should have an oily sheen if they are fresh.
Lighter roasted coffee beans will only have some of the oils on
their surface. If the beans don’t have any oil on their
surface, then they are likely not fresh-roasted.
If you enjoy flavored coffee, flavor the coffee yourself after
brewing with one of the available natural and organic coffee flavors
you can purchase at many natural food stores. Generally, beans
that are already flavored before you purchase them are lower grade
coffee beans, since producers know the flavor added after roasting
will cover up the lower grade taste of the coffee.
What does “shade grown”
mean?
Coffee grows naturally in the shade; however, 70 percent of the
world’s coffee is now grown in full sun. The coffee industry
has created hybrid coffee plants that can tolerate full sun and
produce more coffee beans, which has led to the clear cutting
of rain forests in order to grow more cheap coffee. Purchasing
shade grown coffee ensures the coffee you are purchasing is grown
in its natural environment, under the canopy of trees. An additional
benefit is the flavor of shade grown coffee: since coffee varieties
present in shade coffee farms are the older plants, they produce
fewer beans more slowly, and consequently offer a richer tasting
coffee.
Also look for organic coffee, since coffee is treated with chemical
fertilizers and pesticides, and Fair Trade Certified™ coffee,
to ensure that the farmers growing and harvesting your coffee
are treated ethically and paid a fair wage for their crop.
What region produces the best tasting
coffee?
Even though coffee is believed to have originated in the Ethiopian
region and that region still produces wonderful coffee, all coffee
growing regions produce great tasting, high quality coffee, and
all regions also produce low quality coffee. Low quality coffee
is the stuff you generally get at a low price and is usually grown
on huge coffee plantations and is not shade grown, organic, or
fair trade. High quality coffee is typically grown on small family
plots (usually less than an acre). Single origin coffee selections
will have distinct flavors, whereas a coffee blend will contain
several origins to give that blend a unique flavor.
Kevin is the owner of Blue Smoke Coffee
Roasting Co., an area carbon neutral, craft coffee roastery providing
fresh roasted-to-order coffee using only organic, fair trade and
shade grown beans. Visit www.bluesmokecoffee.com,
or look for the coffee at New Bridge Market and Sprig in Asheville,
The Happy Hiker and Whole Earth Grocery in Gatlinburg, TN, and
the Chattanooga, TN, Greenlife Grocery.
Chocolate for Me,
Please!
Theresa Green helps you love hot chocolate
even more by sharing its health benefits and new ways to enjoy
the winter staple.
Traditional hot chocolate is a sugary concoction that may appeal
to a sweet lover’s taste buds, but what about those of us
who want to receive the health benefits of chocolate without the
negative side effects of milk and sugar?
The Mayans and Aztecs loved cacao, the bean chocolate is made
from, and used to crush it and mix it with chili peppers to create
a spicy, bitter drink they believed gave them sacred wisdom and
knowledge. Only in the past couple of years has chocolate mixed
with chili peppers become available in the United States.
Adding a pinch of cayenne and a dash of cinnamon to your hot chocolate
is a great after meal drink because it helps with digestion and
circulation.
Another delicious combination with your hot chocolate is a little
ginger, cardamom and just a pinch of clove. This gives your hot
chocolate a chai flavor and also is great for your digestive process.
And, of course, there’s the all-time favorite, peppermint
with chocolate. Just half a drop of peppermint essential oil to
your hot chocolate gives a nice minty flavor and also the added
health benefit of peppermint essential oil, another herb that
is good for digestion.
If you have trouble relaxing and unwinding after work, try a cozy
cup of cocoa with Kava Kava and a pinch of nutmeg. Kava Kava is
an herb the Polynesian islanders drink to open up and relax. They
say it helps to overcome shyness and relaxes the muscles.
Theresa Green is the
owner of Primitive Chocolate. You can find Primitive’s UliMana
line of raw chocolate ready-to-be-heated-up-with-a-bit-of-milk
mixes in the raw section at Greenlife Grocery and in the local
honey section in Earth Fare (both regional natural foods markets).
The mixes are made with raw honey, agave, organic raw cacao powder,
organic cinnamon, organic vanilla bean and various spices.
