Is coffee good for the heart? Two recent studies have come up with completely opposite answers, leaving coffee lovers at a loss as to what to do.

A study presented at a meeting of the British Cardiology Association found that drinking five cups of coffee a day was no worse for the heart than drinking one less cup of coffee. The study suggests that even if you drink 25 cups of coffee a day, it's still harmless to your heart health.

But another study found that drinking too much coffee, such as more than six cups of coffee a day, increases the risk of cardiovascular disease. Elina, co-author of the study and director of the South Australian Cancer Research Centre, said: "from a nutritional point of view, we all want to know how much coffee is excessive, and that's our answer.]

The study found that people who drank one or two cups of coffee a day were 11 per cent more likely to develop cardiovascular disease than those who did not drink coffee and 7 per cent higher than those who drank decaf. "Coffee contains caffeine and is a stimulant, which increases the activity of the nervous system and increases blood pressure, and too much coffee makes the heart work harder," Elina said. Therefore, if you drink too much coffee, it will keep your heart working under high pressure and for a long time, which is bad for your heart.]

In addition, Professor Elina also pointed out that some coffee is not filtered in the manufacturing process, coffee contains caffeine alcohol, caffeine can increase blood LDL cholesterol, but also cause the risk of cardiovascular disease.

To sum up, scientists' views on coffee have been debated for a long time. Some studies think that coffee is good for health, while others think that coffee is bad for health. For example, there have been studies in the past that moderate coffee is good for health. In addition, a study published last year at the American Cardiology Association found that drinking coffee could lead to heart failure and stroke. Because 7% of heart failure and 8% of strokes are associated with people drinking more than one cup of coffee a week.

As a result, an expert from the American Cardiology Association said that although a lot of research has been done on the effects of coffee on the human body, scientists are still unable to come to a complete and well-documented conclusion that people should not drink coffee. Therefore, according to your body's ability, as long as you don't drink too much coffee, it's harmless to your body.
