Various studies have shown contradictory results about coffee consumption.
Some studies suggest that moderate coffee consumption of one to two cups a day may reduce the risk of diabetes and dementia. The caffeine is also a "mood enhancer" and a temporary energy boost, at the expense of a drop in energy when the effects wear off, typically in an hour or two. Caffeine is also popular among weight lifters and athletes for it's performance enhancing potential, because it helps them exert a higher level energy level for peak performance.
Consider some of the potentially negative effects of coffee:
Since caffeine is habit forming, coffee drinkers often find it hard to drink only one to two cups per day. Too much caffeine may irritate the bladder, leading to urinary tract infections in men and women, and also prostate inflammation in men. Also excessive caffeine may cause the excretion of essential minerals in urine.
Commercially grown coffee has been found to be high in pesticides, so organic coffee is better. Also coffee may be contaminated with fungus and the mycotoxins produced by fungus. The best coffee to drink daily is coffee that is free from fungus. Coffee grown at high altitudes is more prone to have fungus, suggesting that organic coffee from lower altitudes is probably best.
Another concern is the creamers and sweeteners that are often added to coffee. Artificial creamers as sweeteners should not be regarded as healthy "foods", and may have long term toxicity. Stevia and Xylitol are generally considered healthy alternatives (see sweeteners) to sugar and artificial sweeteners. Organic cream or milk from grass-fed cows, that have not been given hormones and antibiotics is the safest for everyday consumption. This type of cream is becoming easier to obtain at regular grocery stores. Otherwise, it may be available from local health food stores.
Too much coffee may cause over consumption of caffeine. One 8 ounce cup of coffee contains about 100 milligrams of caffeine. Caffeine may cause side effects of nervous energy and increase blood pressure, although the effects are generally temporary, and it is not believed to cause chronic high blood pressure (also known as hypertension).
Considering all of the potential risks, it may be better to avoid coffee. If you want the potential health benefits without the potential risks, drinking one or two cups of a fungus-free organic coffee may be the ideal solution, with only the natural creams and sweeteners. Since coffee lovers usually have coffee every day, it may be well worth the effort and cost to choose the best kind of coffee, because the foods we consume every day have the greatest cumulative long term health benefits or risks.
