Coffee: How Bad is it Really? http://www.mercola.com/2003/dec/10/coffee.htm By Dr. Joseph Mercola
with Rachael Droege Although coffee is one of the most heavily researched commodities and studies have spanned decades, there is still much controversy surrounding its ill effects, or lack thereof, on health. Study after study is performed--often with conflicting results--and it seems there is always a new study out to discount the last one. Still, the average American adult consumes over 10 pounds of coffee per year, which amounts to a total of 2.4 billion pounds a year in the United States alone.
It appears that drinking coffee may interfere with your body's ability to keep
homocysteine and
cholesterol levels in check, most likely by inhibiting the action of the vitamins folate, B12 or B6. Coffee has been previously associated with increased risk of
stroke and
rheumatoid arthritis. Studies have also shown that caffeine in coffee can raise blood pressure and levels of stress hormones, and if consumed in large quantities it can lead to heart palpitations, jitters and nervousness.
With that said, coffee is clearly not the healthiest liquid to drink--the best choice is pure water--but coffee and caffeine are far less dangerous than
fruit juice or
soda. While I do believe that eliminating, or at the very least limiting, coffee should be one of your goals, if you are in the midst of other dietary changes, such as those outlined in my
nutrition plan eliminating coffee can be put toward the bottom of the list, and you should strive to eliminate soda and fruit juice from your beverage list first.
There are, however, some important facets of coffee that you should know before you have your next morning cup.
Coffee and Pregnant Women
Pregnant women should NEVER drink coffee. Caffeine is a stimulant drug that easily passes through the placenta to the developing fetus and is also transferred through breast milk.
During pregnancy and in infants the half-life of caffeine is increased, which means that it will stay in your body, and your infant's body, longer. Moreover, fetuses have no ability to detoxify caffeine.
Research suggests that drinking more than 300 mg of coffee daily, or the equivalent of two to three 8-ounce cups, may increase the risk of miscarriage, birth defects such as cleft palate and low birth weight, although as I mentioned above I don't believe that ANY amount coffee is safe for pregnant women.
Even with moderate caffeine intake, when the woman experiences no effects, studies have found changes in both the mother's and the fetal heart rate and blood pressure. Preliminary studies also suggest that drinking four cups of coffee or more per day may put the infant at an increased risk of sudden infant death syndrome (SIDS). Caffeine may also make it more difficult for women to maintain necessary levels of iron and calcium, which are especially important during pregnancy.
It also appears that coffee consumption is associated with increased estrogen levels, which means an increased risk of breast and endometrial cancer.
Coffee also has the issue of pesticide contamination, which is
particularly harmful during pregnancy. You can read more about this issue below.
Coffee and Pesticides
Coffee is usually not grown in the United States and we therefore have no control over how many pesticides are sprayed on coffee crops. As such, coffee is a heavily sprayed crop, so drinking coffee is likely to expose you to a dose of pesticides with each cup.

How to Wean Yourself Off Coffee
If you try to stop drinking coffee "cold turkey" you will likely experience symptoms of withdrawal that can include severe headache, fatigue and depression. This can be avoided by cutting down the amount you drink gradually over a period of days or even weeks. It's also important to drink plenty of water during the process in order to keep your body well hydrated.
If you find that you miss your morning coffee-drinking ritual, replace it with a new tradition that will also boost your health and energy. Vegetable juice makes a great coffee replacement, and if you're in a hurry you can try
Living Fuel Rx Superfood. Both options will give you the energy boost that you're looking for in the morning without the negative effects of caffeine.
While you're in the process of weaning yourself off coffee, here are some tips to reduce the chance of harmful effects until you can completely eliminate it:
- Use organic coffee. As mentioned above, coffee is a heavily sprayed crop, so drinking organic coffee might reduce or eliminate your exposure to toxic herbicides, pesticides and fertilizers. It will also help the people working in the coffee fields, as they will be exposed to fewer pesticides as well.
- Try "Swiss Water Process" decaf. If you are going to drink decaffeinated coffee, be sure that it uses a non-chemical based method of decaffeination. The "Swiss Water Process" is a patented method and is the best choice. Most of the major brands are chemically decaffeinated, even if it says "naturally decaffeinated" right on the container. If you are unsure of the methods, contact the manufacturer.
- Avoid sugar and milk. These are actually much worse for you than the coffee itself. Don't compound the detrimental health effects by adding milk or sugar to your coffee.
- Only use unbleached filters. If you use a "drip" coffee maker, be sure to use non-bleached filters. The bright white ones, which most people use, are chlorine bleached and some of this chlorine will be extracted from the filter during the brewing process.

I think it's a bit inconclusive at this point...but I'm curious and may do some of my own research. Now, if people are loading creamer, sugar, whole milk, etc in their coffee, I can see that having an effect.
. The caffeine also helps with my migrains and allows me to take less prescription meds.
