Stay away from spicy foods and chilli peppers if you are a victim of digestive problems. These hot foods can irritate and burn your oesophagus, resulting in heartburn pain.

Processed Foods

Acidic Fruits

If you are susceptible to heartburn, it’s better to stay away from coffee, as it stimulates acid production in your stomach. Caffeine also increases inflammation and acts as diuretic, which means it dehydrates you quicker, along with diarrhoea and cramping, if drank excessively.


If you suffer from gastrointestinal disorders, even alcohol in moderation can irritate your digestive tract. Alcohol is toxic for the stomach and relaxes the oesophageal sphincter. This leads to inflammation of the stomach lining and induces cramping as well as heartburn.
