Hi.
Thanks for posting query at HCM. 
You maybe familiar with the common mechanism of 
gastroesophageal reflux disease (
GERD) ; however i will briefly explain:
Food enters in to stomach from 
esophagus via lower esophageal sphincter (LES) . If LES fails to close/contract effectively food content from stomach may reflux into the esphagus leading to GERD.
Certain food may lead to relaxation of LES and/or increase 
gastric acid production. :
1. chocolate 2. caffeine.   3 Alcohol.     4. fatty meal.    5. citrus fruit and tomato
If you have a history of GERD that has been treated successfully , then advise is:
1. avoid chocolates; carbonated drinks,
2. avoid tomato juice, decrease salt intake
3. minimum alcohol intake and try quit 
smoking ( if your a smoker)
4. eat your dinner at least 2 to 3 hours before going to bed
5. raise your head by placing two pillows under your head before sleeping
Hope to answer your concern 
Further questions are most welcome
Regards
Dr Tayyab Malik
