Coffee has both advantages and disadvantages. Please drink it safely.

According to a report by Hong Kong's Ming Pao, laboratory tests show that there are 150 to 200 milligrams of caffeine in an ordinary cup of instant coffee on the market, of which Starbucks has the highest caffeine concentration. Office workers are refreshed by three cups in the morning, afternoon and evening, which has exceeded twice the recommended maximum intake of 300 mg for adults.

In addition to excessive coffee consumption can cause nervousness, irritability, anxiety, handshakes and insomnia, caffeine can also cause calcium loss, so try not to drink coffee for the elderly, children and people with osteoporosis.

Wen Shaojun, chief physician of the Department of Cardiology at Anzhen Hospital in Beijing, told reporters that caffeine helps speed up fat decomposition, but at the same time, it depends on muscle exercise to convert excess fatty acids into heat energy consumption. Without matching exercise, excess fatty acids flow back down the bloodstream and re-accumulate fat. So after drinking coffee, you need to be active at the same time in order to contribute to fat consumption.

Zhong Lirong, vice president of the China Coffee and Coffee Beverage Professional Committee, pointed out that caffeine is the most controversial ingredient in coffee, but there are still many low-caffeinated or non-caffeinated coffee on the market for people who are sensitive to caffeine.
