Someone on an acid reflux diet can use olive oil, says U.S. News. An example of an oil that does trigger acid reflux is mint oil.
The only time that oils should be avoided on an acid reflux diet is if they are used to deep-fry foods, U.S. News states. The greasiness and high fat content of fried foods trigger acid reflux and heartburn. These foods are also a lot harder to digest and stick around longer. Those with acid reflux need to stay away from the herb mint or anything containing mint oil. Extra-virgin olive oil is a good oil to eat and a better alternative for those with heartburn than butter. Dairy products such as butter have high levels of fat that exacerbate acid reflux. Low- or non-fat dairy foods should replace regularly fat dairy.
There are very few foods that trigger acid reflux, according to U.S. News. Other than deep-fried foods and mint, they include chocolate, alcohol and coffee. While people believe that spicy foods and tomatoes are triggers as well, they are not. They can cause pain amidst an acid reflux attack, but they do not cause the attack. Instead, the esophagus is already irritated, so these acidic and spicy foods merely irritate it more.
