I Am Often Bloated And Gassy, Especially After Eating. And,

I am often bloated and gassy, especially after eating. And, my stomach frequently makes weird noises, noisy and embarrassing. This has been going on for months. Sounds like my tummy is processing something. Could this be my diet? What should I eat and avoid. I watch what I eat, especially checking on the sat. fat, cholesterol, sodium, sugar and fiber. Would appreciate your input. Oh, I was on GERD meds for a few years but stopped a year ago. These symptoms do not feel like GERD. Thank you.
