The efficacy, effects and contraindications of coffee

The efficacy and effects of coffee

Coffee is a common drink that not only has the effect of refreshing the mind, but also has many other benefits. First of all, coffee contains caffeine, which is a substance that can stimulate the central nervous system. Moderate intake of caffeine can increase human alertness and concentration, and improve work and study efficiency.

Secondly, studies have shown that drinking coffee in moderation can improve athletic performance. Because caffeine stimulates muscle contractions and reduces pain, drinking a cup of coffee during long or high-intensity exercise can delay fatigue and increase endurance levels.

In addition, moderate coffee intake is associated with a lower risk of certain diseases. For example, multiple studies have found that regular consumption of black coffee can reduce the risk of type 2 diabetes, Parkinson's syndrome, Alzheimer's disease and other neurodegenerative diseases.

Contraindications

However, coffee is not suitable for everyone. First, for some people, consuming too much caffeine may cause adverse reactions such as palpitations, insomnia, anxiety, etc. These people include pregnant women, breastfeeding women, heart patients and individuals prone to anxiety.

Secondly, long-term and heavy coffee drinking may also have negative health effects. High doses of caffeine intake have been linked to osteoporosis, stomach ulcers, and digestive problems. In addition, over-reliance on caffeine for alertness may also cause the body to develop tolerance to it and experience withdrawal symptoms.

How to drink properly

To properly enjoy the benefits of coffee and avoid its potential risks, here are some suggestions:

1. Control your intake: Drink moderately according to your individual situation and health status. It is generally recommended to consume about 300-400 mg (about 2-4 cups) per day.

2. Avoid drinking on an empty stomach: Drinking coffee on an empty stomach may cause excessive gastric acid secretion, causing stomach pain or indigestion. It is best to drink coffee 30 minutes after eating.

3. Pay attention to time control: avoid drinking coffee at night or before going to bed to avoid affecting sleep quality.

4. Diversify your choices: Try to choose pure black coffee instead of latte or cappuccino with too much sugar, creamer, etc. This can reduce the intake of extra sugar and fat.

in conclusion

In general, moderate coffee consumption is safe for most people and can provide some benefits. However, everyone has different tolerance to caffeine, and the amount of coffee consumed should be adjusted appropriately according to individual circumstances. If you have any health problems or special circumstances, please seek advice from your doctor before drinking.
