Coffee (pictured) and tea are very popular among Hong Kong people. Many people even drink more coffee or tea than water every day. However, excessive consumption of caffeine may lead to addiction, palpitations or rising blood pressure. The best daily caffeine intake for adults is 200 mg or less, that is, about one cup of coffee.
In recent years, the Centre for Food Safety has collected 80 types of coffee and milk tea from various restaurants in Hong Kong. the results show that coffee prepared by soaking in tea restaurants contains the most caffeine, while Hot Tea, HK Style is not comparable to each other. the caffeine content is higher than that of ordinary Chinese green tea or oolong tea. In fact, there are many other types of drinks on the market that contain caffeine. Some raw materials contain natural caffeine, such as chocolate drinks, while others are added caffeine, such as cola sodas and energy drinks.
Caffeine is generally considered safe, but every caffeine intake of more than 300 mg is a large dose, which may lead to acute poisoning, including headache, nausea, hyperactivity, anxiety, palpitation and insomnia. However, different people have different metabolic rates and different responses to caffeine.
In addition, long-term intake of a small amount of caffeine, such as 100 mg a day (equivalent to a lighter cup of coffee), can lead to dependence on caffeine. If you do not drink tea or coffee for a day, there will be withdrawal symptoms (Withdrawal Symptoms), such as headache, fatigue, fatigue, inability to concentrate on work, depression and so on. In addition, caffeine can also interfere with calcium absorption and increase the risk of osteoporosis.
If you have heart palpitations or rising blood pressure after drinking coffee or tea, you should stop drinking immediately. If you have the habit of drinking coffee or tea every day, it is best to keep the daily dose at or below 200 mg. Parents should avoid caffeinated drinks such as sodas and energy drinks for their children.
