The role of drinking coffee coffee and tea are good for heart health

When it comes to heart health, coffee has a bad reputation, while tea is considered good. Whether you drink tea or coffee, we want to tell you the good news: coffee and tea are good for heart health.

The link between coffee and health is not a new topic. In 17th century Europe thought that coffee was good for digestion and painful wind but could lead to impotence and paralysis-drinking coffee was considered not a good thing at that time, although this was not true. Nowadays, people pay more attention to coffee and heart health questions.

Some researchers think coffee is bad for the heart, but others (perhaps coffee drinkers) keep refuting it. For non-habitual coffee drinkers, caffeine in two cups of coffee increases blood pressure by two or three mm Hg;, but not for habitual coffee drinkers. Coffee causes the heart rate to increase for a short time, but does not cause the heart rate to be abnormal. Brewed coffee or unfiltered coffee is rich in coffee oil (oils), which can increase total cholesterol and LDL cholesterol, but if filtered, these chemicals will not exist, so most coffee has no effect on cholesterol levels. Some studies have suggested that coffee can cause hardening of the arteries, but others have found that two cups of coffee a day can help relax the arteries.

In the study of coffee and health effects, cardiologists pay attention to high blood pressure. Coffee does not cause high blood pressure. If you have high blood pressure and like coffee, you can continue to drink coffee. Many studies have shown that there is no increased risk of coronary heart disease among coffee drinkers, regardless of whether they drink conventional coffee (caffeinated coffee) or decaf coffee. The results of more than 10 years of monitoring studies provide sufficient evidence for us to conclude that coffee does not cause heart disease, on the contrary, coffee can be used as a part of a healthy diet.

Over the years, some researchers have paid attention to whether coffee is harmful to people who already have coronary heart disease, that is, whether drinking coffee can cause heart disease in people with coronary heart disease. The answer is: yes, coffee can cause heart disease, but the risk is very small. And it doesn't apply to all coffee drinkers. For sedentary people, if they are not used to drinking coffee and they have heart disease risk factors, a cup of coffee in the morning may increase their risk of heart disease, but the risk is very small; people with these characteristics may exaggerate changes in blood pressure and nervous system activity after drinking a cup of coffee, which can lead to coronary artery plaque disorders. Other studies have shown that the link between coffee and heart disease is partly influenced by genes. A study in Costa Rica found that people who have a slow metabolism of caffeine may have an increased risk of heart attack after drinking coffee. On the whole, however, the risk of heart disease caused by coffee is so small that there is no need to worry.

So, how was the tea party? Originally, it is very difficult to compare coffee with tea, because tea drinkers usually have healthier eating habits and lifestyles than coffee drinkers, so we really can't tell you which is very good after all. Observational studies have shown that, like coffee, both black and green tea help to reduce the risk of coronary heart disease, but it usually takes 5 to 6 cups of tea a day to help. So what on earth should you drink? Materials show that coffee and tea are not only harmless to the heart, but also good for you. What you drink depends on your taste preference. Avoid drinking brewed and unfiltered coffee because they add cholesterol. If you need to add sugar to your coffee, please choose a low-calorie, low-fat one.
