It never ceases to amaze me how difficult it is to assign cause and effect. I have eaten the same thing, exactly, days apart, same size portion and found that one day i get bad reflux and another, i dont.
This causes me to wonder about the previous meal, or when i took my meds, or was it the food plus the exercise that day, or so many other vriables...difficult to know.
I ve eaten garlic for years, cooked, and even raw on occasions and still got gerd. Maybe the harmful things i did counter weighted or overwhelmed the good the garlic did...or maybe just my body chemistry is different.
Untangling this problem is like walking thru a maze.
Here is an excellent article from a medical journal i found on the net about why and how the LED malfunctions
"Pathophysiology of GERD: Lower Esophageal Sphincter Defects"
