But coffee also contains diterpenes, which increase the risk of cardiovascular disease

In addition, coffee can also affect the body's absorption of some minerals
.
For example, after drinking a cup of coffee, the absorption of iron in breakfast will be reduced by 39%, even if drinking 1 hour after breakfast, iron absorption will still be affected
.
Also drinking coffee can cause calcium loss, so if you have symptoms of osteoporosis, the daily caffeine intake should not exceed 300 mg (equivalent to 2 to 3 cups of coffee)

Is caffeine safe?
In 2015, the European Food Safety Authority conducted a comprehensive assessment of caffeine and found that there is no safety concern for normal adults to consume 400 mg of caffeine per day (equivalent to 5 cups of coffee)
.
.
The average Chinese consumes only 4 to 5 cups of coffee per year, so at present, there is no need to worry too much about the adverse effects of caffeine on Chinese people
.
In addition, the European Food Safety Authority also reminded the public that daily intake of 100 mg (about 1 cup of coffee) caffeine may affect people's sleep
.
Therefore, if you are afraid of affecting your sleep, it is best not to drink coffee

Does coffee cause cancer or fight cancer?
In 1991, the International Center for Research on Cancer rated coffee as a Group 2B carcinogen (probably carcinogenic to humans)
.
More than 20 years later, scientists have not stopped researching coffee
.
In 2016, the World Health Organization convened scientists to reassess and found no firm evidence of a link between bladder cancer and coffee
.
Therefore, the World Health Organization has removed coffee from group 2B carcinogens and moved it to category 3 (no carcinogenic risk to humans)
