They don't listen bc it's all not true. Your junk diet is the cause of your problems. Your junk diet has fostered an incredibly wrong gut flora, and that is the cause of indigestion.
Quit sugar and other sources of fructose outside of whole foods. Things like HFCS, honey, nectar, juice, molasses, maple syrup and white flour products (most breads, crackers and pastas).
Unless you have celiac. you aren't intolerant of gluten. You cannot physically be allergic to fruit, so THAT is also BS.
Doctors know this (except the fructose part).
Your current diet is killing you. I know that you are addicted to fructose, but quitting isn't that hard. Addiction causes the brain to try to rationalize further use by not listening to logic.
That's why you are dismissing this message before trying it out for a month and seeing what happens.
More addiction experience than you'll ever have.
