Around one in 10 British adults mistakenly think coffee causes cancer,so says a survey carried out by the World Cancer Research Fund (see here). Nothing can be further from the truth – repeat, drinking coffee does not cause cancer. In fact, the benefits of coffee have been largely understated. Among the benefits include:
2.Reducing the incidence of Parkinson’s Disease and Alzheimer’s. Read “A Cup of Coffee a Day will Keep Alzheimer’s Away”.
3.Protecting against diabetes. Moderate consumption may lower the risk of type 2 diabetes in younger and middle aged women.
4.Preventing liver disease and the formation of liver and kidney stones.
5. Promoting alertness, attentiveness, and wakefulness.
But its not all good and no bad. Drinking excessive amounts (more than four cups a day) has been shown to accelerate osteoporosis as well as increase blood pressure, palpitations and even increase the risk of hardening of the arteries (a process called atherosclerosis). In some, coffee can cause heartburn, or GERD(gastro -esophageal reflux disease).
An important point to note is that there seems to be a health hazard in drinking unfiltered coffee (as in Turkish coffee and kahawa) as it raises blood cholesterol. Filtered coffee, as in instant coffee, does not do so, as diterpenes, responsible for raising cholesterol, are removed by filtration.
What about heart disease? The verdict’s not in just yet..on one hand, diterpenes cause a rise in cholesterol and homocysteine but this seems balanced by the beneficial anti-oxidant properties. As of now, there is no convincing evidence that coffee leads to heart disease.
Bear in mind that this discussion is based on just pure plain coffee. The scenario changes quite a bit with additives like milk, cream and sugar. For one thing, a cup of latte at Starbucks can contribute about 260 calories (as opposed to 0 calories in plain coffee). This is not to mention the health risks of added fats (and cholesterol) and sugar.
