The relationship between coffee and various diseases

For drinking coffee, many people have specifically raised criticism that it may pose a threat to cardiovascular and bone. In recent years, more and more studies believe that the so-called "threats" are mostly misunderstandings.

Coffee not linked to heart disease

American researchers have analyzed published data on coffee and heart disease over the past 30 years and found no relationship between coffee consumption levels and heart stroke. Previous reports of a positive correlation between coffee consumption and coronary heart disease in women were actually confused with smoking. The survey showed that 23 percent of women who drank one cup of coffee a day smoked, and 56 percent of those who drank more than six cups a day smoked. Therefore, people mistakenly think that the more coffee they drink, the higher the risk of heart disease. In fact, this is the harm of smoking.

Coffee raises blood pressure temporarily

In coffee never-drinkers, blood pressure increased significantly after drinking 2 to 4 cups of coffee for a week, but this was temporary. Researchers who studied 7506 men and 2095 women found that the increase in blood pressure after drinking coffee for the first time decreased after a week, and that drinking coffee every day thereafter had a lower average blood pressure than non-coffee drinkers. Thus, some people's conclusions about coffee raising blood pressure are confused by temporarily elevated blood pressure.

Coffee has no causal link to arrhythmia

American experts on cardiac arrhythmias have refuted the idea that drinking more than two cups of coffee may cause arrhythmias in sensitive people. Taking the most common premature ventricular contraction as an example, they studied 7311 men aged 35 to 37 and found that drinking seven to eight cups of coffee a day, or even more than nine cups, was not associated with premature contractions. Expert analysis, arrhythmia frequency and age are proportional, and age increase is often proportional to the amount of coffee drinking, so the so-called "drink more coffee, arrhythmia more" conclusion, in fact, the older the arrhythmia more error.

Coffee does not affect bone calcium levels

Some people have found that calcium is lost in the urine of menopausal women after drinking coffee, suggesting that bone calcium loss is also related to coffee. American osteoporosis experts, who measured the bone mineral density of 138 postmenopausal women who drank coffee, concluded there was no link. Experts explain that although a little more calcium appears to be excreted in the urine after one cup of coffee, calcium intake throughout the day is sufficient to compensate for the insignificant calcium loss caused by one cup of coffee. Therefore, drinking coffee does not pose a threat to bone strength.

Coffee is a good medicine, in moderation.

There have also been reports in recent years that coffee can cure diseases: adults who drink coffee regularly have a 30% lower incidence of asthma than non-coffee drinkers; those who are allergic to pollen drink 2 to 3 cups a day (200~250 ml per pregnant) coffee containing a total of 400 mg of caffeine, symptoms can be significantly reduced; coffee can give pleasure; the brain effect of coffee can make drinkers responsive, in the accident deaths, coffee drinkers than non-drinkers 40% less; coffee can alleviate mental depression symptoms, drinking coffee suicide than non-drinkers 70%.
