Coffee is a hot drink made from roasted coffee beans. It is a dark, bitter and slightly acidic beverage with a stimulating effect on the body mainly due to its caffeine content.
It is the second most popular hot beverage in the world behind tea. It is also a good source of vitamins and minerals.
Coffee, a fragrant brown liquid that contains caffeine, has a rich history that stretches back thousands of years. It is thought to have been first discovered in Ethiopia, but it has also been found in Yemen and other parts of the world.
According to one legend, an Ethiopian goat herder named Kaldi noticed that his goats had unusual energy after eating the berries of a particular shrub. He shared his discovery with an abbot, who made a drink out of the berries to keep his monks alert for their evening prayers.
Eventually, the shrub grew in popularity and the word spread about its stimulating effects; Sufi Muslims used it to aid concentration during prayer and to stay awake during long nights of meditation. In the 15th century, coffee was introduced to southern Arabia.
It spread rapidly throughout the Arab world and was also exported to Europe in the 16th century. It was initially banned by Islamic authorities, but it soon became the favored beverage of the rich and famous in Europe.
Caffeine is a chemical compound that is widely consumed around the world in the form of coffee, tea, cacao beans, kola nuts, the leaves of yerba mate and the seeds of guarana. It is also synthetically created and added to beverages such as sodas and energy drinks.
It has many benefits, including a boost in energy, focus and mood. It is also an anti-inflammatory and antioxidant agent, which helps protect against heart disease, cancer and liver disease.
However, too much caffeine can be harmful to the body. The level of caffeine that is too high can vary among people, and it may be hard to tell how much is too much for you.
In his practice, cardiology physician Michael Marcus tells patients who have trouble sleeping or experiencing abnormal heart rhythms to take a break from caffeine. He recommends that they try drinking less of it, or even decaffeinating their coffee to see if this makes a difference.
Coffee has been linked to a number of health benefits, including reduced risk of diabetes, heart disease and cancer. It also can help you maintain a healthy weight, and can enhance physical performance and endurance.
The primary reason for its health benefits is caffeine, which is a natural stimulant that helps to increase your alertness and energy levels. Caffeine can also boost your metabolism and help you burn fat.
In addition, coffee has been shown to reduce the risk of liver disease and cancer. The antioxidants in coffee can protect your liver cells from damage and decrease the breakage of DNA strands that lead to cancer.
Research has also found that drinking coffee can reduce the risk of Alzheimer’s disease and Parkinson’s disease. Moreover, it can also help improve your memory and thinking skills.
Coffee is a brewed beverage that is a popular choice for many people. It is made from roasted beans of the Coffea plant, which contains caffeine and chlorogenic acid.
Caffeine helps wake up your body and improve alertness, concentration, and mental acuity. Moderate intake can also help with weight loss, improved mood, and better energy levels.
However, too much caffeine can cause headaches, anxiety, irritability, trouble sleeping, chest pain, and frequent urination. Some people are more sensitive to caffeine and may experience these side effects even at lower doses.
Some studies have shown that drinking coffee may reduce your risk of certain cancers, including those of the lining of the esophagus (esophageal cancer). It also appears to lower your risk of heart disease and high blood pressure. But more research is needed to know for sure if coffee can reduce your risk of these diseases.
