I don't think that's correct. Lower stomach acid pH makes the LES close more tightly, with a max around pH==3.
Having the right amount of stomach acid and low PH is crucial to keep the whole digestive system, gut motility and more running properly.
I am assuming the best thing I can do for it is lose weight, but that's easier said than done.
It sounds like there's this thing "PRAL" or "potential renal acid load" https://en.wikipedia.org/wiki/Potential_renal_acid_load where the affect on stomach acid can be different from a food's pH. But again, the wikipedia article links to some random people's blogs and a single research article from 2019. I'm not sure if this is well supported by research.
| The aim of this study was to investigate if a dietary supplementation containing: melatonin, l-tryptophan, vitamin B6, folic acid, vitamin B12, methionine and betaine would help patients with GERD,

1) Don't drink while eating or exercising, drink 30min before or 2 hours later.

4) Right before going to bed, don't drink and try using the bathroom.
In other words, good posture.
