About 60 million Americans suffer from heartburn at least once a month. It happens when the lower esophageal sphincter muscle (LES) cannot prevent stomach acid from splashing into the esophagus. This may result in an acidic ashy feeling in the chest, a bitter taste in the throat, or a gassy sensation in the stomach. Several types of food contribute to indigestion and other symptoms of heartburn. Manage bad heartburn by avoiding the following foods:

Fried foods
Fried foods typically contain a high amount of unhealthy fats. This results in delayed digestion, which increases the pressure on the LES. Consuming large portions of fried foods may put you at risk of heartburn or acid reflux. You may want to stay away from fatty foods like French fries, cheese, ice cream, potato chips, donuts, and pastries. Replace the heavy or creamy dressings of your salad with a dash of olive oil and herbs. Limit the consumption of fried bacon, sausages, chicken, high-fat sour cream, dips, and high-fat meats like marbled sirloin or prime rib.

Spicy and acidic foods
According to some studies, eating spicy foods can lead to abdominal pain. It can also cause a burning sensation in the chest if you have a gastrointestinal disorder. A chemical compound called capsaicin that gives the food a spicy flavor can irritate the esophagus. Additionally, fruits and vegetables that have a high acidic content may also damage the esophagus. Limit the consumption of tomatoes and tomato-based sauces. Also, avoid lemons, pineapple, oranges, and grapefruit and instead opt for berries, melons, and strawberries to neutralize some of the acids.

Beverages
Drinks that contain gas force open the LES, resulting in a burp. This can promote symptoms of heartburn. The high sugar content in some drinks may result in bloating and cause a feeling of uneasiness. Avoid or limit the intake of carbonated beverages and sugary drinks. Even coffee and tea may trigger symptoms of gastroesophageal diseases (GERD). Consumption of alcoholic beverages can cause heartburn. According to a 2009 study, beer, red and white wine relax the LES and promote gastric acid secretion. Some individuals may experience symptoms after one drink, while others may be able to tolerate more quantity. Pay attention to your symptoms and avoid drinks that do not suit your body.

Other foods and supplements
There are various other foods, medicine, and supplements that cause heartburn. These include chocolates and chocolate-based drinks like hot cocoa and mocha, peppermint in teas or mouthwash, and processed foods such as burgers, breakfast cereals, bread, and cakes. Certain medicines and supplements may worsen heartburn, including aspirin, antibiotics, bisphosphonates, alpha-blockers, nitrates, calcium channel blockers, tricyclics, theophylline, and iron or potassium supplements. If you notice heartburn or acid reflux symptoms after taking a medicine, consult a doctor before stopping them.
