3 Reasons To Avoid Drinking Your Morning Coffee On An Empty Stomach

3 Reasons Why Coffee on an Empty Stomach Can Hurt You

Drinking coffee on an empty stomach is a daily ritual for many, but it may come with hidden costs that can affect your health. Whether you're looking for an energy boost or the familiar comforting aroma, there are compelling reasons to reconsider this habit. Below, we explore three key reasons that highlight why your morning cup might be best enjoyed with some food in your stomach.

1. Increases Stomach Acidity

Coffee is naturally acidic, and when consumed on an empty stomach, it can significantly increase the acidity levels in your stomach. This is particularly troublesome for individuals who may already be prone to digestive issues. When you drink coffee without any food, the acid can irritate the stomach lining, leading to discomfort, heartburn, or even gastritis over time. Here are some of the effects this increased acidity can cause:
  • Stomach discomfort and pain
  • Increased risk of acid reflux
  • Potential long-term damage to the stomach lining
If you simply can’t imagine going without your morning brew, consider pairing your coffee with a light breakfast or at least having a glass of water beforehand to buffer its acidity.

2. Affects Mental Clarity and Energy Levels

Many people believe that coffee enhances their focus and energy, especially in the morning. While caffeine does provide a temporary boost, consuming coffee on an empty stomach can actually have the opposite effect in the long run. When your body is deprived of nourishment, coffee can increase the production of cortisol, the hormone associated with stress. Elevated cortisol levels can lead to feelings of anxiety and fatigue, rather than the alertness you may be hoping for. The impacts can include:
  • Increased anxiety and stress levels
  • Fatigue or energy crashes post-caffeine
  • Difficulty maintaining focus due to fluctuating blood sugar levels
To optimise your mental clarity and energy, consider integrating balanced meals into your morning routine. Pairing your coffee with protein or healthy fats can help stabilise your blood sugar and keep those unwelcome side effects at bay.

3. Disrupts Nutrient Absorption

Consuming coffee on an empty stomach can interfere with your body’s ability to absorb essential nutrients. Certain compounds in coffee, including tannins, can bind to minerals and hinder their absorption, making it more challenging for your body to benefit from the vitamins and nutrients you consume. This disruption can contribute to deficiencies over time. Here are some specific nutrients that could be negatively impacted:
  • Iron absorption may decrease, leading to fatigue or anaemia
  • Calcium absorption may be hindered, affecting bone health
  • Magnesium absorption issues could lead to muscle cramps and other problems
To maximise nutrient absorption, try to consume coffee after a balanced meal rather than on an empty stomach. This approach allows your body to more effectively utilise the nutrients from your food while still enjoying your morning cup.


In summary, while coffee can be a beloved part of your daily routine, consuming it on an empty stomach may not be the healthiest choice. By thinking critically about your coffee habits, you can protect your stomach health, improve your energy levels, and enhance your body's nutrient absorption. Transitioning to a more balanced morning approach may not only elevate your mood but also promote better overall wellness. Consider adjusting your morning coffee ritual by ensuring that your stomach is not in a fasting state. This small change could pave the way for a more pleasant and health-conscious start to your day. Embrace the power of food alongside your coffee and enjoy the benefits that come with it!
