What you eat first thing in the morning can affect your overall health. 

They say that breakfast is the most important meal of the day and some foods are ideal for kickstarting your metabolism. 

However, others can lead to discomfort and even long-term health issues.

Here are five foods you should avoid eating on an empty stomach and why.

Coffee

You might not like to hear this because many of us are guilty of having coffee first thing in the morning. 

Unfortunately, this can lead to increased acid production, which might cause stomach discomfort, acid reflux, or even worsen pre-existing gastritis. 

Additionally, coffee stimulates the production of cortisol, the stress hormone, which can disrupt your natural hormonal balance when consumed on an empty stomach.

Avoid drinking coffee in the morning.

Citrus fruits

Citrus fruits like oranges, lemons, and grapefruits are rich in vitamin C and antioxidants.

However, their high acidity can irritate an empty stomach, potentially causing heartburn or gastritis. 

Over time, excessive consumption in this state may harm your digestive lining.

Spicy foods

Spicy foods can irritate the stomach lining and increase acid production, potentially causing indigestion or a burning sensation. 

When eaten on an empty stomach, the effects are magnified, leading to greater discomfort.

Spicy foods can irritate the stomach lining.

Sugary foods or drinks

Sugary foods like pastries or sugary beverages can spike your blood sugar levels, providing a quick energy boost followed by a crash. 

This rollercoaster effect can lead to fatigue and cravings later in the day. 

Eating sugar on an empty stomach can also strain the pancreas, which must produce insulin to regulate blood sugar levels.

Carbonated drinks

Cool drinks or sparkling waters can irritate your stomach lining when consumed without food. 

The carbon dioxide in these drinks may cause bloating, gas, and discomfort, especially when your stomach is empty and more sensitive.
