However, not everyone can benefit from coffee. First of all, excessive coffee drinking may lead to caffeine poisoning. Excessive caffeine intake can cause uncomfortable symptoms such as palpitations, insomnia, and anxiety.

Secondly, long-term and heavy coffee drinking may have a negative impact on cardiovascular health. High doses of caffeine can increase blood pressure and heart rate and increase the risk of heart disease and stroke.

In addition, drinking black coffee may also cause tooth stains and bad breath problems. Due to the presence of melanin in coffee, long-term drinking of black coffee can cause teeth to turn yellow and sometimes produce unpleasant breath.

Moderate intake can bring many benefits, such as improving concentration and promoting metabolism, while excessive intake may bring a series of negative effects, such as insomnia and cardiovascular problems.
