I came across an article online about the correlation between coffee and heart disease. I would like to summarize and share some of the interesting points here. The article says that having coffee more frequently can lower the risk of suffering a heart disease by 50%. The goal is to have 3 cups of coffee per day. The other day, a research team in China conducted further investigation on about 180,000 British people registered on Bio Bank in England. The research result showed that those people who have three cups of coffee per day have a 48.1% reduced risk of suffering heart disease. The team discovered that the amount of coffee, tea and caffeine consumed is inversely proportional to the rate of heart disease occurring. Hence, the team claimed that caffeine can be helpful(beneficial) for good health contrary to common belief. Another research in 2022 showed that grabbing a few cups of decaf, regular and instant coffee once a day can drastically decrease death rate and rate of heart disease occurring. On the other hand, we need to watch the condition and health of our teeth. There is an increased risk of getting oral cavities when we drink more coffee. Because people, who smoke, drink alcohol and coffee very often, have a high risk of suffering gum disease. So, It is highly recommended that people in this category visit their dentist to get rid of their tartar every three to six months because leaving tartar can cause gum disease. According to this article guidelines, I'll try to have some coffee and watch my teeth and gum health in the future.
