I've been experiencing heartburn lately, and think it's diet based. what foods should i avoid?

May vary: I would consider going to a doctor who may order tests that hopefully will indicate which foods to avoid. Everyone is different in their tolerance of certain foods. You could also keep a food diary and write down what you might have eaten, time and how much prior to getting the heartburn. Meds and supplements should be considered too.

Keep check of which: foods cause you sx's. Avoid smoking, alcohol, coffee, tea, caffeine & carbonated beverages. See if specific foods are triggers such as chocolate, corn, fried foods,dairy, fatty food, potato chips, creamy or oily dressings, marbled sirloin, high fat bakery items, raw onions, tomatoes, potatoes, spearmint, & peppermint. Orange, cranberry or grapefruit juice & lemons or lemonade can be problematic.
