Coffee is one of the absolute worst drinks you can put into your body. Not only is intaking caffeine bad for you due to the chemical changes it has on your body, but the chemicals additives to most coffee. If you ingest one chemical it will offset the others in your body without maintaining a strong balance of what nature intended. If you drink decaf the chemicals used to extract the caffeine are often times worse than the effects of the caffeine itself. Here are the scientific facts of coffee:
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.
