You should cut down on: Alcohol, caffeine, and coffee in all forms, tomato based and other acidic foods.
Heartburn caused by reflux can usually be controlled with a few lifestyle changes, starting with adopting a low fat diet that includes a balance of protein, starches, and fiber rich vegetables and fruits. Fatty foods takes longer to digest and thus slow down the rate of food emptying from the stomach. Coffee including decaffeinated brands, promotes high acid production; so does tea, cola drinks and other sources of caffeine. There is no evidence that spicy foods - except possibly, red and black pepper- cause indigestion, but people who find that a highly spiced meal is followed by discomfort would be better off shunning such seasonings.
Avoid large meals, especially late in the day and try not to eat in the two hours before bedtime. Sit up straight after meals; bending over, slouching or lying down increase pressure on the stomach and promote reflux. Stop cigarette smoking; nicotine relaxes the muscular sphincter between the esophagus and stomach. Limit alcohol intake to an occasional glass of wine or beer.
The use of nonprescription antacids to treat heartburn by neutralizing or suppressing stomach acid is questionable ; the problem is not too much acid but instead, acid in the wrong place. If you find they do help, how ever, follow the instructions and never take them for longer than recommended.
