Thank you for your question Sad Esophagus, Sad Taste Buds.
A dozen foods or groups of foods are known to irritate the stomach and esophagus, causing inflammation, triggering acid reflux.
One group includes Alliums – onions, garlic, shallots, leeks and Brassicas – cabbage, broccoli, cauliflower, brussel sprouts, bok choy.
These vegetables are high in naturally occurring organosulfur compounds. Sulfur is part of hundreds of physiological processes and is an important element to our healthy.
Sulfur also causes stomach gas, bloating, thus promoting acid reflux in some people. The extent organosulfur compounds breakdown or degrade during cooking is unknown at this time.

Digestive problems are very different from person to person, and as you know, especially for those with acid reflux.
Many foods, even healthy ones, can be problematic and encourage acid reflux. The food that triggers your reaction (causes you to have acid reflux) may not cause a reaction for someone else.
This can make it difficult to know what you should avoid in order to control the symptoms and manage your condition.

With any medical condition, it’s very important to consult with a physician and in a case like this, you may also want to seek out the advice of a registered dietitian.
Both professionals can help you make the necessary adjustments to the way you shop and prepare food at home and how to make the best choices when eating away from home.

Hope this information is helpful to you and others.

Cutting out chocolate and reducing coffee are bad enough, please help me find a way to fit some onions back into my eating!
