Coffee is one of the daily necessities for many people, but how many cups of coffee should be drunk every day to avoid excess coffee has always been the focus of public attention. in this regard, dietitian Lin Shihang recently pointed out in the Food and Drug Administration's Drug Food Safety News that as long as the total daily caffeine intake does not exceed 300 mg, that is, a maximum of 1-3 cups of coffee a day, and then adjust according to their own physique and feelings. You don't have to worry.

Many people love and hate coffee, mostly from the wrong understanding of coffee. In this regard, Lin Shihang sorted out three major coffee myths for the public: first of all, many people think that drinking coffee can cheer you up, in fact, it is not refreshing, but "can't sleep." caffeine does affect hormones related to the physiological clock, but everyone has different sensitivity to caffeine, and some people can't sleep after drinking coffee. But there are also people who sleep, and everyone should drink the right amount of coffee according to their own physique.

Caffeine metabolism time is about 8 hours, and varies from person to person. If you are worried that you can't sleep at night, stop drinking caffeinated foods and drinks after noon, or choose coffee with lower caffeine content.

In addition, with regard to coffee addiction, Lin Shihang mentioned that heavy coffee drinkers are prone to withdrawal symptoms of headache and hand shaking once they stop drinking coffee, but they can be greatly relieved in only two weeks, and it is recommended that the total daily caffeine intake should not exceed 300 mg.

In addition, there are also different opinions on whether pregnant women can drink coffee. Lin Shihang cited empirical evidence that according to data, if pregnant women drink too much coffee when early embryos are unstable, caffeine intake is proportional to the increase in abortion rate. as for the idea that coffee may lead to fetal malformations, according to the current research data, caffeine is not directly related to fetal malformations.

Lin Shihang also suggested that everyone's physique is different, whether pregnant women can drink coffee, and how much coffee they drink during pregnancy, it is more safe to consult a doctor first and follow the doctor's advice.
