Basic knowledge of fine coffee caffeine should not exceed 300mg every day

Some people are still restrained in the face of coffee, no matter how much they enjoy it, and there is a reason for this. Bobo, a senior dietitian who has long been engaged in beverage culture promotion and publishing, believes that busy urban people should adhere to the principle of moderation when enjoying coffee.

A digestive study at Stanford University School of Medicine in the United States has set a safety label for caffeine intake: no more than 300mg a day. A cup of coffee (the porcelain cup size of the hotel coffee shop) contains about 120mg caffeine, while a can of Coca-Cola contains about 55mg, and a cup of green tea contains about 15mg. Due to the irritation of caffeine, people with stomach problems or relatively fragile intestines and stomach should not drink more. People with hyperthyroidism or fast heartbeat drinking coffee will also cause discomfort such as rapid heartbeat and mental agitation, and pregnant women or mothers who are breastfeeding should also avoid caffeine. In addition, coffee beans are roasted, so drinking coffee is easy to catch fire, if they are hot and dry physique, easy to get angry, insomnia, dream friends should also be careful. People who know that they are not suitable for drinking coffee should try their best to avoid it, but if they are really uncomfortable, then of course they should choose a small cup and just taste it.
