"Fit for Life" is a diet that came out about 20 years ago and has sold many millions of copies. They have a website called fitforlifetime. They make no claims about gerd. The only evidence that it works is based on the one-off experience of my friend. I have other friends who use it who do not have gerd. They like it too. It is based on Tao. The book that describes the original philosophy is called, "The Tao of Health, Sex, and Longevity." Again, I am not recommending it, merely asking if anyone can add further evidence either way.
In the meantime, remember what your mother told you and chew every bite 50 times! It's not much advice but it does help a little!
