Foods and Factors That Can Trigger Acid Reflux

Scribbled Underline

Tomatoes and tomato-based products:

Tomatoes are naturally acidic, and foods like tomato sauce, ketchup, and salsa can contribute to acidity.

Spicy foods

Spices like chilli, pepper, and curry can relax the lower oesophagal sphincter (LES) and lead to acid reflux.

Fried and fatty foods:

High-fat foods, such as fried foods, butter, and fatty cuts of meat, can slow digestion and promote acid reflux.


Chocolate contains both caffeine and theobromine, which can relax the LES and increase acid production.

Carbonated beverages:

Soda and carbonated drinks can expand the stomach and increase pressure on the LES, causing acid reflux.

Coffee and caffeinated beverages:

Caffeine can relax the LES and stimulate acid production, leading to heartburn.


Alcohol can relax the LES and irritate the oesophagus, making it more prone to acid reflux.

Citrus or fruit juices:

While most fruit juices are acidic, citrus juices like orange and grapefruit are particularly problematic for some individuals.

Stress and anxiety:

Emotional stress can sometimes exacerbate acid reflux symptoms.
