Coffee Pros & Cons

Posted by medliorator on December 20, 2007

For moderate coffee drinkers (3-4 cups/day providing 300-400 mg/day of caffeine), there is little evidence of health risks and some evidence of health benefits.

The “Pros”

1. Antioxidants
2. Regular coffee consumption reduces the risk of Parkinson’s disease.
3. Coffee consumption is potentially protective against the development of type 2 diabetes.
4. Coffee drinking may protect against liver cirrhosis, especially alcoholic cirrhosis.
5. protective against gallstone formation
6. lowers the risk of kidney stones formation.
7. Improved mental performance.
8. Regular coffee consumption seems to protect against Alzheimer’s disease.
9. Caffeine can open airways and improve asthma symptoms.

The “Cons”

1. caffeine can increase the risk of heart attack, especially among those people who carry the “slow” gene variant for the enzyme that metabolizes caffeine. diterpenes cafestol and kahweol present in unfiltered coffee and caffeine each appear to increase risk of coronary heart disease. High quality studies have confirmed the cholesterol-raising effect of diterpenes. Coffee consumption is also associated with an increase of plasma homocysteine, a risk factor for coronary heart disease.
2. Heavy consumption of boiled coffee elevates blood total and LDL cholesterol. Unfiltered coffee contains two cholesterol-raising compounds cafestol and kahweol.
3. Coffee negatively affects the blood vessel tone and function (increases arterial stiffness and wave reflections).
4. Coffee can cause …cardiac arrhythmias
5. Although coffee consumption is not a significant risk factor for hypertension, it produces unfavorable effects on blood pressure and people prone to hypertension may be more susceptible.
6. Coffee intake may induce an extra urinary excretion of calcium. Heavy coffee consumption (4 cups=600 ml or more) can modestly increase the risk of osteoporosis, especially in women with a low calcium intake.
7. A cup of coffee can trigger heartburn.
8. High amounts of caffeine taken before going to sleep, can cause restlessness and difficulty falling asleep, tendency to be awakened more readily by sudden noises, and a decreased quality of sleep. However, some people can drink coffee and fall right asleep.
9. Dehydration.
10. Dependence. You may get a few days of headache and irritability if you choose to quit
