🔹 Pro Tip: If you experience stomach irritation, consider switching to low-acid coffee or drinking coffee after breakfast instead of before.
6. Limit Your Daily Coffee Intake
While coffee has health benefits, excessive caffeine intake can lead to side effects like anxiety, insomnia, rapid heart rate, and digestive issues.
✅ Recommended Daily Coffee Intake:
- For most adults: Up to 400 mg of caffeine per day (about 3-4 cups of coffee).
- For pregnant women: No more than 200 mg per day (about 1-2 small cups).
- For caffeine-sensitive individuals: Reduce intake or switch to decaf coffee.
🚨 Signs You May Be Drinking Too Much Coffee:
- Jitters or nervousness
- Rapid heartbeat or palpitations
- Trouble sleeping
- Increased acid reflux or digestive discomfort
🔹 Pro Tip: If you rely heavily on coffee, try alternating between regular coffee and decaf to gradually reduce your caffeine dependence.
7. Choose the Healthiest Brewing Method
Different brewing methods can affect the health properties of coffee. Some methods retain more antioxidants, while others increase cholesterol levels due to coffee oils.
✅ Healthiest Coffee Brewing Methods:
- French Press or Espresso: Retains coffee oils, which provide antioxidants but may raise cholesterol levels.
- Drip Coffee (Filtered Coffee): Removes most of the coffee oils, making it the best choice for heart health.
- Cold Brew Coffee: Naturally lower in acid, making it gentler on the stomach.
🚨 Less Healthy Brewing Methods:
- Unfiltered Coffee (Turkish or Boiled Coffee): Contains cafestol, a compound that can raise LDL (bad cholesterol) levels.
🔹 Pro Tip: If you have high cholesterol, use a paper filter to reduce cafestol levels in your coffee.
