Certain foods can contribute to acid reflux, such as chocolate, drinks with caffeine, fried food, mint and peppermint flavored candy, spicy food, garlic, onions and of course citrus fruits like grapefruit, lemon and limes.

Title : Indigestion and What to Do About It (Dr. Morton Walker Health Book S)
Author : James F. Balch
Rating : 1 Stars out of 5.
Summary : The book is about alternative medicine rather than heartburn
This book is not about heartburn. The first part of the book is about all manner of digestive problems, and then even about disorders purportedly related to digestive disorders. The second part of the book suggests that good diet (especially yogurt), enemas, and something called probiotics will cure all diseases, and therefore incidentally also heartburn (which thus has served only as a marketing come-on to lure in buyers). I believe there is much to be learned from alternative medicine, but this book actually offers very little rigorous (supported) information. For entertainment, and in closing, let me quote a tidbit. "Make the coffee enema by boiling six heaping tablespoons of ground coffee (not instant) in two quarts of water for fifteen minutes, cooling to a comfortable temperature, and straining..." It is probably a very good idea to let that boiling coffee cool a little before the anal consumption, but why is instant coffee not good, and how does this fix heartburn?
Keep a food diary to track everything you eat and drink if you suffer from acid reflux as diet plays a part in generating stomach acid, and if the acid levels are managed and kept low then you are less likely to experience the reflux.
If your acid reflux and heartburn is worse at night, try raising the head of the bed. That way your esophagus is higher up than your stomach and less acid would trickle back up the wrong way. But before you start chopping off two legs of the bed, or put bricks under two others, adding another pillow or two could do the trick too.
