Hi~ I Seem To Be Getting Heartburn Or Acid Reflex

Hi~ I seem to be getting heartburn or acid reflex late in the day and early evening. Is there a food I can consume to rid of it naturally. Also some burping. Feels acidy at the back of my throat. I thought consuming a teaspoon of apple cider vinegar would help. It isn't. Suggestions? Thanks Kate 67 yrs. old.
