Coffee myths
1. Common Coffee Myths
While working in the coffee business i often come across a lot of questions about common
and some uncommon coffee myths.
As with any product used to excess, consumers often wonder about the health
consequences. And researchers readily oblige. Hardly a month goes by without a report
that hails coffee, tea or caffeine as healthful or damns them as potential killers.
Can all these often contradictory reports be right? Yes. Coffee and tea, after all, are complex
mixtures of chemicals, several of which may independently affect health.
Caffeine Myths
Through the years, the public has been buffeted by much misguided information about
caffeine and its most common source, coffee. In March the Center for Science in the Public
Interest published a comprehensive appraisal of scientific reports in its Nutrition Action
Healthletter. Its findings and those of other research reports follow.
Hydration. It was long thought that caffeinated beverages were diuretics, but studies
reviewed last year found that people who consumed drinks with up to 550 milligrams of
2. caffeine produced no more urine than when drinking fluids free of caffeine. Above 575
milligrams, the drug was a diuretic.
So even a Starbucks grande, with 330 milligrams of caffeine, will not send you to a
bathroom any sooner than if you drank 16 ounces of pure water. Drinks containing usual
doses of caffeine are hydrating and, like water, contribute to the body's daily water needs.

Coffee Leads To Heart Disease?
It has long been thought that "coffee", as a stimulant, would lead to various forms of heart
disease. The recent literature.however, suggests that coffee is safe in moderate doses.
Recently, one researcher, Warren G. Thompson, M.D., noted in a 1994 literature review on
this subject: "The largest and better studies suggest that coffee is not a major risk factor for
coronary disease."
Additionally, a major study conducted by Willet, et al., examined data collected from more
than 85,000 women over a 10-year period. Upon adjusting the data for known risk factors
such as smoking, they found no increased risk of CVD for women who drank six or more
cups of "coffee" per day.
A 1990 study by Diedrich, et al., looked at 45,000 men. It found no link between coffee,
caffeine and CVD in men who drank four or more cups of coffee per day.
3. Coffee Causes Ulcers
Often times, when people see me drinking a cup of "coffee" they give the warning "You
shouldn't drink coffee, it will give you ulcers." The thinking, until recently, was that excess
stomach acid caused ulcers and that "coffee" would contribute to the stomach acid. Recent
studies however show that most ulcers are caused by a particular bacteria, namely
Helicobacter pylori. Those ulcers can be cured easily with antibiotics. An important
distinction to make is that while coffee or spicy foods for that matter don't cause the ulcers,
they may serve to aggravate existing ulcers.
Coffee Is Bad For Reproductive Health
Miscarriage, low birth weight, infertility. These are all commonly associated with being
increased with coffee consumption. However, there has been little convincing evidence that
a moderate amount of caffeine during pregnancy will cause these conditions.
Scientists have had trouble linking consumption of coffee to miscarriage. There are many
confounders in this area. As an example, it has been found that women who don't
experience nausea during pregnancy are more likely to miscarry. This could be due to them
being less likely to stay away from foods and beverages that cause nausea. Therefore,
coffee could be lumped in together with many other things that are consumed that should
be avoided.
Furthermore, studies have also shown that women who drink more than three cups of
coffee daily are at no increase risk of infertility or delayed conception.
