1. Caffeine in coffee: pros and cons

Caffeine is the main ingredient of coffee. It has a certain diuretic effect and can promote metabolism, thereby helping the body detoxify. Caffeine is also a stimulant. Excessive intake may cause insomnia, palpitations, anxiety and other problems. Caffeine may also aggravate gastric ulcers, gastroesophageal reflux and other diseases in some people. For the pros and cons of caffeine, we need to weigh our personal constitution and intake.

2. Effects on the Cardiovascular System

Studies have shown that there is a certain association between moderate coffee drinking and a reduced risk of cardiovascular disease. This may be because some antioxidants in coffee help reduce inflammation and protect blood vessels. This does not mean that coffee is harmless. Excessive coffee drinking, especially high-concentration coffee, may have a negative impact on the cardiovascular system. People with cardiovascular disease should drink coffee with caution.

3. Impact on bone health

Long-term and excessive drinking of coffee may lead to calcium loss, thus affecting bone health.

These people should control their coffee intake and supplement calcium appropriately.

4. Affects sleep quality
