Coffee is a well known bean that is used across many different cultures and countries. The reason why it is so well known is that it tastes great and is known to stimulate the nervous system. This creates alertness in the mind and body, allowing for better functioning throughout the day. While coffee is not addictive, too much dependence or sudden withdrawals can cause headaches and other unwanted symptoms. Green tea that has been decaffeinated can be effective as a weight loss tool. Coffee that is boiled or percolated has been known to have negative effects on the heart. It may also cause complications with circulation and can raise cholesterol levels. It is also best to avoid caffeine from coffee as it can exacerbate premenstrual symptoms, also commonly known as PMS. Please consult a medical professional if you experience any of these painful symptoms listed above.
