Like Homo sapiens, coffee has its origins in East Africa. Coffee still grows wild in certain regions of Ethiopia. And the Ethiopians have a delightful story about the origin of coffee drinking.

Apparently, a shepherd was out with his goats one day and fell asleep. When the shepherd went to gather his goats, he noted that some of the goats were quite frisky and energetic. These same goats were eating a red cherry- like fruit. According to the legend, the shepherd decided to try the red fruit and also felt more alert and energetic, and so human’s love of coffee began.

Coffee made its way from East Africa across the Red Sea into the Mocha region of Yemen and from there into the Muslim world. Westerners who traveled to Istanbul and other Muslim areas provided the first reports of the new black drink to Europe.

( For those interested in reading more of the fascinatin­g history of coffee, I recommend two books: “Uncommon Grounds,” by Mark Pendergras­t, and “The Devil’s Cup,” by Stewart Lee Allen.)

Although coffee contains a myriad of beneficial bioactive chemical compounds, it is caffeine that we are most familiar with. It is a compound that stimulates the central nervous system and gives us that feeling of energy, alertness and concentrat­ion that we associate with coffee. However, caffeine can become toxic if we consume more than 300 to 400 mg per day.

People who ingest more than this amount may exhibit tremors, insomnia, nervousnes­s and anxiousnes­s. Withdrawal symptoms can also occur when heavy caffeine users abruptly stop using caffeine. The most common withdrawal symptom is headache. The website caffeine

informer. com has a list of the caffeine content of several popular caffeinate­d beverages and products. For example, a Venti Blonde Roast from Starbucks has about 475 mg of caffeine; three tablets of GNC amp ( pre- Post) supplement have 400 mg of caffeine; and an 8- ounce cup of Lipton Green Tea has 16.4 mg of caffeine.

In October, the British Medical Journal published a comprehens­ive review of many studies of health and coffee. The authors found that coffee was “more often associated with benefit rather than harm for a range of health outcomes.” There was noted to be a reduction in all- cause mortality, cardiovasc­ular mortality and cardiovasc­ular disease.

This review also found that coffee drinkers had a lower risk of prostate cancer, endometria­l cancer, melanoma, adult leukemia and liver cancer. There was also noted to be a reduced risk of gallstones, gout and Type II diabetes.

Harmful effects of coffee were noted in pregnancy. Coffee consumptio­n was associated with lower birth weights, increased pregnancy loss and possibly increased risk of childhood leukemia. There also was a slight associatio­n between high coffee consumptio­n and the risk of fractures in women.

So, what does this all mean for you?

Most of the benefits occurred in people who drank three to four cups of coffee per day as long as the caffeine amount did not exceed the 300 to 400 mg level described above. I recommend checking out caffeine informer.
