It really does matter what you eat on an empty stomach, as it affects how you feel for the rest of the day. If there are recommendations on what to eat for breakfast, there are also lists of what not to eat.

Foods to avoid on an empty stomach

• Tomatoes: Although tomatoes are rich in vitamins and antioxidants, they also contain tannic acid, which can increase acidity and cause discomfort when eaten on an empty stomach. Tannic acid is a natural compound that, in larger amounts, can irritate the stomach lining.
  
  
• Coffee: Drinking coffee on an empty stomach can increase the production of stomach acid, which in some people leads to discomfort such as heartburn. Coffee can also relax the lower esophageal sphincter, allowing acid to flow back into the esophagus.
  
  
• Citrus fruits: Oranges, lemons and other acidic fruits can cause issues such as heartburn or esophageal inflammation when eaten on an empty stomach, especially for people with sensitive stomachs.
  
  
• Carbonated drinks: Carbonated drinks, whether sweetened or not, can damage the stomach lining and reduce blood flow to the stomach when drunk on an empty stomach, leading to discomfort.
  
  
• Sugary drinks: Consuming sugary drinks on an empty stomach can rapidly increase blood sugar levels, which in turn increases hunger and food cravings.
  
  
• Spicy spices: Spices such as ginger and pepper can strongly stimulate the secretion of stomach acid and damage the stomach lining when consumed on an empty stomach.
  
  
• Yogurt: If you eat yogurt on an empty stomach, stomach acid may destroy the probiotic lactobacilli, reducing its beneficial effects.

Foods suitable for consumption on an empty stomach

• Eggs: Eggs are an excellent source of protein and essential amino acids. Eating eggs for breakfast can prolong the feeling of satiety and help control hunger.
  
  
• Oatmeal: Oatmeal protects the stomach lining from harmful acids and lowers cholesterol levels. It also contains fiber, which keeps you fuller for longer.
  
  
• Nuts: Walnuts, hazelnuts, and almonds normalize the stomach’s pH level and reduce the risk of ulcers. Their healthy fats also keep you full longer.
  
  
• Buckwheat: Buckwheat is rich in protein and iron and aids digestion. It is an excellent choice for breakfast, as it improves digestion and is packed with vitamins.
  
  
• Blueberries: Blueberries are rich in antioxidants, fiber, and vitamins. Eating blueberries can be key to maintaining a healthy heart and blood vessels.
  
  
• Watermelon: Watermelon is made up of 92% water and is excellent for keeping your body hydrated. It also contains lycopene, which is beneficial for the heart, skin, and blood sugar levels.
  
  
• Honey: Honey helps intestines work better, supports digestion, is good for immunity, and has antiviral and antibacterial effects.

Choosing the right foods on an empty stomach is vital for maintaining your health and well-being. By following these recommendations, you can improve your digestion, boost your energy levels, and reduce the risk of stomach problems. Remember, every individual is unique, so listen to your body and adapt your diet to your personal needs.
