Because salmon is considered to be a highly acidic food, it can aggravate acid reflux or heartburn in those who already have problems with it. Those who are prone to heartburn will probably want to avoid eating a lot of salmon because of the fact that it is so acidic.

Even though you may enjoy the taste, it will be important to limit how much you eat on a regular basis, especially if you know that you already have problems with acid reflux as it is. There are certain foods which are acidic and others which are more alkaline and salmon happens to be part of the former.
