What are the most negative effects of coffee use?!
I've been using coffee to keep my mind off of things and such!.Www@FoodAQ@Com
Answers:
What are the Cons!?
? Coffee is a central nervous system stimulator that gives the adrenals a
kick and causes production of the stress handling hormone adrenalin and
the production of more cortisol resulting in short term benefits of
heightened awareness / alertness and more energy, but long term may
result in a crash after each consumption to lower levels of energy than
previously thereby necessitating another cup and another cup, etc!. Thus,
it may be addictive and ultimately may result in adrenal exhaustion!.
? Even though coffee has never been conclusively linked to cancer, it does
contain acknowledged carcinogens such as caffeine and other chemicals
produced by the high heat of roasting such as creosote, pymdine, tars,
and polycyclic aromatic hydrocarbons!.
? Caffeine interferes with adenosine, a brain chemical that normally has a
calming effect!.
? Cortisol levels are raised which in turn results in constriction of the blood
vessels, harder pumping of the heart and higher blood pressure!.
(Constriction of blood vessels is also a benefit, see the next section!.)
? The liver in fetuses and newborns cannot metabolize caffeine, so it
remains in the body for up to four days stimulating the nervous system
resulting in irritability and sleeplessness!.
? Coffee has been associated with low birth weight, birth defects,
miscarriages, premature birth, inability to conceive, and sluggish sperm!.
? Many of the chemicals in coffee and decaf irritate the stomach lining
causing an increase of stomach acid leading to digestive disorders!.
? Coffee, including decaf, has high amounts of vitamin K, which affects
coagulability of the blood – bad for people at risk of heart attack, stroke
and blood clots!.
? Decreases quality of sleep!.
? Caffeine may cause problems with blood sugar control after meals for type
2 diabetics!.
? Coffee excites more rapid peristaltic movements of the intestines resulting
in shorted transit times and less absorption of nutrients!.
? Coffee hampers the absorption of essential minerals and vitamins such as
magnesium, zinc, iron, potassium, and B’s!.
? Coffee contributes to caries in the teeth!.
? Coffee stimulates more frequent urination and subsequent loss of various
vitamins and minerals such as B, C, calcium, iron and zinc!.
? Caffeine may aggravate osteoporosis by leaching calcium from the bones!.
? Caffeine may increase intraocular pressure in persons with glaucoma!.
? Coffee may interfere with proper levels of homocysteine and cholesterol
by inhibiting vitamins folate, B12 or B6!.
? Coffee is one of most heavily pesticide sprayed crops!.
? Caffeine aggravates stress in people who drink it every day!.Www@FoodAQ@Com

Some research suggests If you drink it excessively it can hurt the lining of your stomach, which may cause ulcers!. But this has not been proven!.Www@FoodAQ@Com
Anxiety, upset stomach, jitters, but caffeine is pretty harmless as long as you dont overdose!. You can overdose off of caffeine, i did off of nodoz one night working the graveyard!. I thought i was having a heart attack, and I kept puking for about two days!. It was probably one of the worst sickness i have ever felt!. But you probably wouldnt overdose as easy drinking coffee!.Www@FoodAQ@Com
If you drink decaf it is a little better for you!. Coffee makes me a nervous wreak!.Www@FoodAQ@Com
Caffeine is a drug that has been widely used for centuries!. Its main
effect is that it is a mild stimulant of the central nervous system (CNS), helping to reduce feelings of drowsiness and fatigue!. However, regular use may lead to "habituation"; that is, no net benefit from use but, rather, a negative effect if the drug is not taken!.
Besides the above-mentioned CNS stimulant effect, caffeine also temporarily increases heartbeat, increases the blood pressure, and stimulates the action of the lungs; increases basal metabolic rate (BMR), and promotes urine production; and it relaxes smooth muscles, notably the bronchial muscle!. Caffeine is used in treating migraine, either alone or in combination!. It enhances the action of the ergot alkaloids used for the treatment of this problem, and also increases the potency of analgesics such as aspirin!. It can somewhat relieve asthma attacks by dilating the bronchial airways!.
Too much caffeine can produce restlessness, nausea, headache, tense muscles, sleep disturbances, and cardiac arrhythmias (irregular heartbeats)!. Because caffeine increases the production of stomach acid it may worsen ulcer symptoms or cause acid reflux ("heartburn")!. Evening use of caffeine may disrupt sleep and cause insomnia!.
Caffeine should be used with caution by people with heart disease and high blood pressure (hypertension), and by those suffering from the eye disease glaucoma!. Caffeine medications should generally not be used in children!. Many children are already consuming significant amounts of caffeine in drinks and food!. In this connection, a nutritional concern is that children may choose fizzy drinks in preference to milk, thus getting "empty" calories at the expense of valuable nutrients!.
As already mentioned, some potentially harmful effects of coffee are recognized, particularly for people who should take few or no stimulants!. Beyond this however, scientific studies of the effects of caffeine have in general failed to prove negative effects, although some have produced contradictory conclusions!. An individual study may produce interesting results which may suggest fruitful directions for further research, but usually it is only when several independent studies confirm one another, and any contradictory results can be accounted for, that one can have reasonable confidence in the safety of a drug -- particularly an " optional" one like coffee!.
Although caffeine does not fall into the class of "addictive" drugs, it may be habit-forming!. Some people may experience headache, fatigue, irritability and nervousness when their daily intake of caffeine is quickly and substantially altered!.
Such "withdrawal effects" may be responsible for confusing results in some studies!. There are many complicating factors in long-term studies!. One is the familiar "convergence of risk-factors" (e!.g!. that coffee-drinkers may be more likely to be smokers)!. Another is that many of the study subjects may deliberately change (or have previously changed) their consumption habits or behaviour, e!.g!. in response to discovering that they suffer from hypertension!. There may also be significant differences in methods of coffee preparation between study populations, or over long periods of time!.
Moderate caffeine consumption during pregnancy is generally considered safe!. A study has not found any effect on low birth-weight or incidence of premature births!. However, although it has been suggested that caffeine may stimulate milk production, cautious mothers may prefer to avoid such beverages during pregnancy or while breastfeeding!.
Furthermore, a large study has not shown any connection of coffee or tea consumption with breast-cancer incidence!. Osteoporosis is another condition which particularly affects women!. Previous studies have suggested caffeine consumption as a risk-factor, but a recent analysis concludes that such an effect is probably not significant except in conditions of calcium-deficiency, which can be easily corrected!.
There is even some actual positive news!. The effect of caffeine on the risk of developing Parkinson's disease, which usually affects older people, has been found to be favourable for men!. For women, previous results have been confusing; but a recent study suggests that a crucial factor may be the effect of hormone levels!. Often caffeine may have a favourable effect against developing this disease; but when combined with hormone replacement therapy (HRT), it may have a negative one!.
One study has found (for women) a strong inverse association between coffee intake and risk of suicide!. However, even if confirmed, to determine whether this might be actual cause and effect is, as usual, a much more challenging problem!.Www@FoodAQ@Com
