The benefits 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 beneficial. Whether you drink tea or coffee, we want to tell you the good news: coffee and tea are good for heart health.

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

Some researchers think coffee is bad for the heart, but others (possibly coffee drinkers) keep refuting it. For non-habitual coffee drinkers, caffeine in two cups of coffee raises blood pressure by two or three mm Hg;, but it does no harm to habitual coffee drinkers. Coffee causes a short-term increase in heart rate, but does not cause heart rate abnormalities. Brewed or unfiltered coffee contains coffee oil (oils), which can raise total cholesterol and LDL cholesterol, but these chemicals do not exist if filtered, so most coffee has no effect on cholesterol levels. Other studies have suggested that coffee can cause arteriosclerosis, but other studies have found that two cups of coffee a day contribute to arterial relaxation.

In the study of coffee and health effects, cardiologists focused on high blood pressure. Coffee doesn't cause high blood pressure. If you have high blood pressure and like coffee, you can continue to drink coffee. A large number of studies have shown that there is no increased risk of coronary heart disease among coffee drinkers, regardless of whether they drink regular coffee (caffeinated coffee) or decaf coffee. The results of more than 10 years of monitoring studies have provided ample evidence that coffee does not cause heart disease, on the contrary, it can be used as part of a healthy diet.

In recent years, some researchers have focused on whether coffee is harmful to people who already have coronary heart disease, that is, whether drinking coffee can cause heart attacks in people with coronary heart disease. The answer is: yes, coffee can cause heart attacks, 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 attack, 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 cause coronary artery plaque disorders. Other studies have shown that the link between coffee and heart attacks is partly influenced by individuals' genes. A study in Costa Rica found that people who metabolize caffeine slowly may have an increased risk of heart attack after drinking coffee. But overall, the risk of a heart attack caused by coffee is so small that there is no need to worry at all.

So, what happens to tea? In fact, it is difficult to compare coffee with tea, because tea drinkers generally have healthier eating habits and lifestyles than coffee drinkers, so we really can't tell you which is better. Observational studies have shown that, like coffee, black and green tea can help reduce the risk of coronary heart disease, but it is generally necessary to drink 5 to 6 cups of tea a day to help reduce coronary heart disease. So what on earth should you drink? Data show that coffee and tea are not only harmless to the heart, but also beneficial. What you drink depends on your taste preference. Avoid brewed and unfiltered coffee as they increase cholesterol. If you have to add sugar to your coffee, please choose a variety that is low in calories and fat.
