By Dr. Mercola
Ifyou're like over half the adult population in the United States, you
drink coffee everyday. By the end of the year, you will have consumed
over 10 pounds of the stuff.
At over 400 billion cups consumed per year,
coffee is the most popular drink in the world. The U.S. imports over $4
billion in coffee each year, and Americans drink 400 million cups per
Why has a substance which places an enormous metabolic burden on
your body and offers no nutritional value at all -- no vitamins, no
minerals, no enzymes -- become so widely used throughout the world?
What’s so Great About Coffee, Anyway?
Many coffee drinkers enjoy the taste. And for those who don’t, there
are countless additives to mask the flavor -- like sweeteners, milk,
and chocolate syrup to name just a few. The list of coffee “enhancers”
is limited only by your imagination.
The other major reason people drink coffee is for a caffeine boost.
Many people swear they can’t get going in the morning without a cup of
coffee -- or several. They feel physically tired and mentally foggy
without their morning brew.
Most regular coffee drinkers argue their habit isn’t doing them any
harm. In fact, they’ll point to reports touting the health benefits of
coffee, citing studies that claim regular consumption reduces the risk
for heart disease and diabetes, for example.
The problem, though, is while coffee’s effect on humans has been
extensively researched for decades, there is still a great deal of
controversy about what it really does to your health. The results of
coffee studies often conflict, which is why you might read an article
this week which completely contradicts the advice given in a report you
read a month ago.
A study conducted in 2004,
for example, indicated drinking coffee may negatively affect your
short-term word recall. Not long after, a report was published which
pointed to evidence that a couple cups of coffee per day could improve your short-term memory.
This is but one example of many which points to the conflicting
information regularly published about the effects of coffee on your
Researchers can’t seem to pinpoint exactly how coffee acts to
allegedly reduce the risk of certain diseases, but they suspect it has
something to do with the anti-inflammatory properties of the
antioxidants in coffee.
The simple fact that remains however is that, coffee is not good for you and it’s not
a health food, as some published reports would have you believe. There
are much better, less risky ways to achieve any professed benefits of
coffee consumption. Don’t use pro-coffee reports or propaganda as an
excuse to hang onto your coffee habit!
The Truth: Coffee Can Wreck Your Health
Among the typical health claims about coffee is it decreases the risk of developing certain cancers and diabetes. However, it increases
your risk for stomach cancer and leukemia. Just like with most drugs,
there are perceived benefits -- and then there are the side effects
which often render the “cure” worse than the disease.
Coffee can also:
- Interfere with your body’s ability to use water, and promote fluid loss
- Raise your cholesterol
- Send your insulin levels out of control
- Contribute to rheumatoid arthritis and stroke
- Damage your blood vessels
- Increase your risk of heart disease
Coffee interferes with your body’s ability to use folate, and
vitamins B12 and B6. Your body needs these nutrients in order to keep
your homocysteine level in the healthy range. Elevated homocysteine
levels are associated with a wide range of serious, even
Chances are the coffee you drink is made from beans grown outside this country.
Coffee beans are known to be a heavily sprayed crop, and the U.S.
has limited input and control over the type and quantity of pesticides
used in the countries from which we import.
Aside from the damage coffee alone can do, pesticides are
contributors to a wide range of health problems, including prostate and
other cancers, Parkinson’s disease, and even miscarriages.
Coffee stimulates your adrenals -- the hormones that activate your
fight or flight response. If your adrenal hormones are stimulated too
often, which is bound to happen if you are a daily coffee drinker, your
adrenal glands may eventually burn out.
When your adrenals no longer function effectively, your body will go
in search of a replacement hormone -- which happens to be progesterone.
Progesterone has its own full-time job to do, part of which is to
keep your body’s estrogen in balance. As your progesterone is used up
compensating for your exhausted adrenals, you run the risk of becoming
Estrogen dominance can lead to osteoporosis.
Coffee also raises the acidity level of your blood, causing calcium
to be pulled from your bones and teeth for use as a buffering agent.
The combination of estrogen dominance and high blood acidity puts you
at an even greater risk for osteoporosis. In fact, research has
established an undeniable link between coffee consumption and hip
A Pick Me Up? Don’t Kid Yourself!
Fatigue is the number one daily complaint among Americans. Are you using coffee to combat feelings of tiredness and low energy?
Caffeine is a strong stimulant and will deliver a temporary jolt, which may feel like a burst of energy to you.
But the truth is, coffee only gives you the illusion of energy and
not the real thing. Over the long-term coffee actually depletes your B
vitamin supply, and lack of B vitamins depletes your energy.
If you struggle with fatigue and low energy on a daily basis, your
body is telling you it’s time to assess your health and lifestyle
choices. Drinking coffee is not the answer to chronic feelings of
weariness and lack of energy.
Caffeine -- Coffee’s Not so Hidden Menace
Caffeine is a psychoactive substance able to alter the way your
brain functions, bringing about temporary changes in your behavior and
The more sensitive you are to the drug, the more pronounced its
effects. Caffeine intoxication is not an uncommon condition --
especially with the high levels of caffeine found in today’s “energy
My firm position is that caffeine is a very powerful drug and should be avoided or strictly limited.
Symptoms and health hazards of caffeine use can include:
- A rise in blood pressure and stress hormone levels
- Heart palpitations
- A sensation of jitteriness and nervousness
- Symptoms of anxiety, especially if you already have a panic or anxiety disorder
- Depletion of iron and calcium levels in women
If you happen to be a protein Nutritional Type™, you are likely
extra sensitive to caffeine. I recommend you consume it only in small
quantities, if at all, and never in the late afternoon or evening, as
it may interfere with your ability to sleep.
A Special Message about Caffeine if You’re Pregnant or Planning a Family
Pregnant women should avoid caffeine entirely, and if you’re a
coffee drinker who is planning a pregnancy, you’ll want to quit the
habit before you conceive.
Studies indicate over 300 mg of caffeine a day, which is the
equivalent of two to three eight ounce cups of coffee, may also
increase your risk of:
- Miscarriage / spontaneous abortion
- Delivering a low birth weight baby
- Having a child with certain birth defects like cleft palate
Four or more cups of coffee a day may increase your baby’s risk of SIDS.
It’s important to realize that any caffeine you ingest passes easily
through the placenta to your unborn child. It is also transferred
through breast milk, and stays in your body -- and the body of your
unborn child or infant -- longer than average. Your unborn baby has no
ability to detoxify the caffeine he or she is exposed to.
A Much Healthier Alternative to Your Coffee Habit
As my regular readers know, my first recommendation for a healthy
beverage is always pure water. It is by far the best choice you can
But if you’re looking to kick your coffee habit to improve your
health, a cup of high-quality green tea can be a great alternative as
a warm, soothing morning beverage.
Green Tea vs. Black Tea
Most types of tea have some health benefits. However, black tea not only contains more caffeine than green tea -- it’s also high in fluoride.
Fluoride is a toxic substance (more toxic than lead) and can have a
profoundly negative effect on your health. It has been linked to
weakened bones, osteoporosis, and even cancer.
Consuming high levels of fluoride can result in a condition called skeletal fluorosis.
Symptoms may include bone pain, calcified ligaments, bone spurs, fused
vertebrae, and difficulty moving your joints. Since Americans are
exposed to fluoride in water, certain toothpastes, coated cookware,
some wines and brands of sparkling mineral water, and several other
sources, it’s important to avoid more of this poison in your tea.
Lesser brands of green tea can also contain fluoride and other
dangerous substances like lead and aluminum, so you must do your
research before settling on a particular brand of tea. I’ll discuss how
to select a high-quality tea a little later.
EGCG: Nature’s Miracle Compound
EGCG, or epigallocatechin-3-gallate, is what is known as a catechin:
- Fresh, unfermented green tea leaves contain polyphenols (naturally occurring antioxidants)
- Within the group of polyphenols are flavonoids
- Flavonoids contain catechins:
- EGCG is the most powerful catechin: found in green tea
Polyphenols are recognized for their disease prevention and
anti-aging properties, and can account for up to 30 percent of the dry
leaf weight of green tea.
EGCG, in particular, boasts an impressive list of illnesses and conditions it has the potential to positively impact.
Powerful Protection for Your Body
Catechins have been researched for hundreds of years for their health-promoting properties, including their ability to help:
- Improve digestion
- Inhibit bacterial and viral infections
- Neutralize the negative impact of harmful fats and oils on your body
- Protect against oxidation in your brain and liver
- Support healthy gums
The powerful antioxidant properties of EGCG can also help your body
fight a number of debilitating conditions like AIDS, Alzheimer’s,
autoimmune diseases, and cancer.
In fact, based on encouraging study results, scientists are hopeful
they will be able to conduct further research on green tea's
protective powers in relation to other autoimmune diseases, including
lupus and rheumatoid arthritis.
Research indicates the polyphenols found in green tea may help fight prostate cancer.
Green tea polyphenols act on molecular pathways to shut down the
production and spread of tumor cells. They also discourage the growth
of the blood vessels which feed the tumors.
These prostate cancer study results show potential for green tea to help fight breast, lung and colon cancer as well.
Promising study results also show EGCG health benefits in the
prevention of arteriosclerosis, cerebral thrombus, heart attack and
stroke. Greek researchers have discovered green tea may help prevent
heart disease, due to its ability to improve blood flow and promote
relaxation of your arteries.
A sizable body of research also suggests the polyphenols in green tea can help:
- Lower your cholesterol
- Lower your triglyceride levels
- Lower your blood pressure
- Ease painful symptoms of rheumatoid arthritis
Obesity and Diabetes Help
A number of studies show EGCG has a regulatory effect on fat
metabolism. It has been shown to improve exercise performance, increase
fat oxidation and prevent obesity.
There is also evidence EGCG may help neutralize toxins in your body
formed by high-fructose corn syrup (HFCS), which can help to reduce the
association between HFCS and diabetes.
EGCG may also protect fatty transplanted livers from ischemia (poor blood flow). Twenty percent of Americans have fatty livers as a result of the growing epidemic of obesity.
Randomized controlled trial results published last year show green
tea extract had a positive effect on glucose levels. Daily dosing with
a powder supplement improved the hemoglobin A1C levels in borderline
Green Tea and Your Brain
Researchers have also discovered green tea has the potential to enhance the function of your brain.
EGCG appears to decrease the production of the protein beta-amyloid,
which can over accumulate in your brain, resulting in nerve damage and
memory loss over time -- a condition related to Alzheimer’s disease.
When researchers injected pure EGCG into mice genetically programmed
to develop Alzheimer’s, results showed a decrease of as much as 54
percent in the plaque which clogs the brains of Alzheimer sufferers.
This is a promising finding that demonstrates the potential for EGCG as
a weapon against the growing scourge of Alzheimer’s disease.
Your Choice of Green Tea Makes All the Difference
Given the healthful properties of green tea, I’m comfortable this is
a drink you can consume in moderation -- especially as an alternative
Keep in mind, though, pure water is what your body was designed to
drink. You don’t want to get too far away from this basic health
principle. Stick to clean spring water and filtered water.
I do not recommend either tap or distilled water, and it’s important to avoid fluoridated water as well.
Next to pure water, I believe a high-quality green tea is a nutritious choice.
A cup of green tea supplies about 20-35 mcg of EGCG. Much of the
research done on the health benefits of green tea has been measured at
three cups per day, so that’s a good number to keep in mind.
If you enjoy green tea -- especially if you’re looking for a healthy
substitute for your coffee habit – add a few cups to your day. Make
sure not to counter the benefits derived from your tea by adding sugar,
milk, or other “embellishments.” Drink your green tea straight.
Make Sure Your Green Tea is Green
Many green teas have been oxidized, which takes away much of the health benefits derived from drinking them.
If your green tea is brown, it has likely been oxidized.
What you want is green tea that’s actually green in color. Ideally,
you want green tea which contains the entire ground tea leaf. Matcha tea is what I prefer. It is of such high quality it can contain over 100 times the EGCG found in regular brewed green tea!
Matcha tea is a vibrant bright green color. It is of much higher
quality than most other green teas, and you can be assured you’re not
consuming fluoride or other toxic substances found in lesser quality
Unlike other teas which you steep and strain, matcha tea is a powder
made from ground green tea leaves. You add the powder right into the
water. You are consuming the whole leaf, which makes matcha tea one of
the healthiest green teas available.
My personal choice, Royal Matcha Green Tea, comes from Japan, is USDA certified organic, and is a premium green tea of the very highest quality.
In general, you want to make sure your choice of green tea is:
- Free of fluoride, lead and aluminum
- Vibrant green in color
in nutrient-rich, clean soil (the majority of green tea is grown in
China, Pakistan and India, where soil conditions can be potentially
Tulsi Tea -- Another Healthy Alternative to Your Morning Coffee
The Tulsi herb is the principle herb of Ayurveda, the holistic system of health practiced in India.
Tulsi is full of antioxidants, which are nutrients that fight the
free radicals in your body and prevent oxidation damage. Cells damaged
through oxidation leave the door open for disease to invade your body.
Research shows antioxidants help your body resist heart disease, Alzheimer’s, Parkinson’s, cancer, and even the aging process.
also contains phytochemicals, compounds which have health promoting
properties. The combination of antioxidants and phytochemicals found
in tulsi can promote your overall health in a variety of ways,
- Support for your immune system
- Improving digestion
- Increasing your resistance to stress
- Promoting healthy metabolism
- Maintaining healthy blood sugar and cholesterol levels
- Providing you with skeletal and joins support
Tulsi tea has a naturally delicious taste -- slightly sweet and a bit spicy.
You can add a natural sweetener like raw honey or Stevia, and raw
milk as desired. You can also drink it iced with a touch of mint.
A Word about Caffeine in Tea
A study published in 2008 in the American Journal of Clinical Nutrition reports the caffeine in tea contains a natural protein, theanine, which actually counteracts unhealthy side effects.
If you are avoiding tea because of the caffeine, you should know
caffeine is much less dangerous to your health than fruit juice or
soda, and in small quantities -- especially the kind found in tea --
should not be reason for concern.
There is one exception: if you’re pregnant or breastfeeding you should avoid ALL caffeine, including in tea.
False Advertising Alert: Beware the “Benefits” of Tea Energy Drinks
The numerous and glowing reports of the health benefits of green tea
have unfortunately created a market for green tea “energy drinks,”
which are being promoted as “natural” weight loss products.
Don’t believe it!
The idea that a product created in a laboratory using a mixture of
chemicals, sweeteners, and caffeine is “natural” or healthy is simply
ridiculous. Tossing in some green tea doesn’t make it any less so.
If you want to drink green tea for its health benefits, stick to the real thing.
If you want to lose weight, do it safely by optimizing your diet, exercising regularly, and getting good quality sleep.
For a cool, refreshing, healthy green tea beverage, try the following:
Tips to Help You Quit Your Coffee Habit
Recipe for Healthy Green Tea Soda
(Prepare in advance, as it can steep in the fridge for about an hour before serving.)
- 2 green tea teabags
- 2 cups (1 pint) boiling water
- Pint-sized Pyrex measuring cup or heat-proof jar
- 1 teaspoon raw organic honey (optional)
- 2 cups total Natural Sparkling mineral water (1/2 glass per serving)
- Place teabags in Pyrex measuring cup or heat-proof jar
- Pour 2 cups boiling water over teabags
- Add 1 teaspoon raw, organic honey (if desired), and stir
- Place mixture in fridge for about 1 hour to cool
- After an hour, remove tea from fridge
- For each serving, pour a half glass of tea into tall ice tea glass
- Add a half glass of sparkling mineral water into each serving
Going “cold turkey” isn’t always a good idea, especially if you’re a
heavy coffee drinker or are especially sensitive to caffeine. As with
most drugs, eliminating caffeine from your system can cause
uncomfortable withdrawal symptoms.
Even one cup of coffee a day can create an addiction. Withdrawal symptoms can include:
- Drowsiness and fatigue
- Trouble concentrating
- Flu-like feelings of nausea and muscle pain
In order to alleviate withdrawal symptoms, you should consider
tapering off your coffee habit -- especially if you drink several cups
If you want to quit drinking coffee gradually, there are steps you
can take during the withdrawal process that will reduce the harmful
effects of the coffee you are still consuming:
- Buy organic to avoid exposure to pesticides
- Avoid coffee additives like sugar, artificial sweeteners and milk – they are worse for your health than the coffee
- Use unbleached coffee filters in your drip coffee maker to avoid chlorine contamination of bleached filters
you switch to decaf, make sure to drink only coffee that has been
non-chemically decaffeinated (for example, the “Swiss Water Process”)
Make sure to follow the nutrition plan for your particular type, get
adequate high-quality sleep and exercise to increase your energy level
Consider using the Meridian Tapping Technique (MTT) to help with your caffeine addiction and withdrawal symptoms.
Remember to substitute a high-quality green tea when you want a
warm, soothing drink. You might also try replacing your morning coffee
with vegetable juice for an energy boost.
Do not make the mistake of substituting fruit juice or soda for
coffee, as they are much worse for you. Remember -- pure water should
be your primary beverage of choice, followed by healthful drinks like
green tea and vegetable juice, in moderation.
There’s No Time Like Today ...
Keep this in mind -- coffee adds zero nutritional value,
and the risks it presents to your health make it a very bad choice
overall. This is especially true if you’re planning a family or are
already pregnant or breastfeeding.
If you use coffee as a crutch to get a quick burst of energy,
remember that cultivating a healthy body and mind supplies all the
power you need to get through your day. The jolt you receive from a cup
of coffee is not only temporary, it’s also depleting your energy stores
in the long term, and very likely wreaking havoc on your body in other
ways as well.
I hope I’ve given you plenty of incentive to quit your coffee
addiction once and for all, and replace it with beverages that can
improve your health and prevent disease. You’ll be pleasantly
surprised, once you make the change to healthier beverages, how much
better and genuinely energetic you feel.
