1. Increased Acidity: Coffee stimulates the production of stomach acid. Consuming it on an empty stomach can lead to increased acidity. This may cause discomfort, heartburn, or indigestion in some people. Over time, it might even irritate the stomach lining, increasing the risk of gastritis.

2. Cortisol Levels: Coffee can elevate cortisol, a stress hormone, especially when consumed in the morning. Drinking coffee without food may cause cortisol levels to spike further. This can lead to jitteriness and anxiety. It may even increase stress over time.

3. Blood Sugar Fluctuations: Coffee can sometimes cause blood sugar levels to fluctuate, particularly in sensitive individuals. Without food, this effect might be more pronounced, leading to energy crashes later in the day.

4. Impact on Digestion: Some studies suggest that coffee can speed up digestion, leading to bowel movements. On an empty stomach, this can happen more quickly, sometimes causing digestive discomfort or urgency.

5. Jitters and Anxiety: Without food to buffer its effects, caffeine can hit harder. It can lead to symptoms like shakiness, jitters, or increased heart rate. These effects occur especially in those sensitive to caffeine.

These effects may vary by individual. It’s often recommended to have a light meal or snack before drinking coffee. This can help reduce potential negative effects on the digestive system and overall well-being.

Whether it’s better to drink tea or coffee in the morning largely depends on individual preferences and health considerations, as both beverages offer unique benefits:

2. Antioxidants: Coffee is rich in antioxidants, which may help protect cells from damage and reduce inflammation .

3. Metabolism Boost: Some studies suggest that coffee can enhance metabolic rate, potentially aiding in weight management .

Benefits of Tea:

1. Lower Caffeine Levels: Tea generally has less caffeine. This can be easier on the stomach. It may lead to fewer jitters for those sensitive to caffeine.

2. Calming Effects: L-theanine in tea promotes relaxation. It enhances mental clarity, making it a good option for a more balanced energy boost without the crash.

3. Hydration: Tea, especially herbal varieties, can be more hydrating than coffee, which is beneficial for overall hydration .

Considerations:

• Individual Tolerance: People respond differently to caffeine; those who are sensitive may prefer tea to avoid jitters.

• Health Conditions: Individuals with certain health conditions might prefer tea for its gentler impact on the stomach. This is particularly true for those with acid reflux compared to coffee.
