Avoid fried, spicy foods and high protien foods.
Especially if gallstones are present!
My oldest sister on Thanksgiving told me that she can't have anything that's fried because she has gallstones. I kindly suggested to her that should just go on and have the gallbladder removed.
She said that she's on medicine for it. I told her that she really should see about having surgery. Both Mom and Grandma had to have them removed.
Too much booze is also a no-no. It depleats the liver's ability to process the alcohol, and your liver's number count increases.
Over time, if excessive consumption of booze continues, it sets up the liver to be a prime candidate for sclerosis - an eventually deadly disease that is irreversible, and the only other hopeful thing is a liver transplant. Actors Larry Hagman and Jim Neighbors had to have theirs replaced.
And even then, because of the extremely heavy demand for liver transplant surgeries, you are then placed on a waiting list. First come, first served.
And who knows how long that'll be? You are then forced to hope and pray to God that a good liver is found for you soon!
When one of my brothers died, his liver couldn't even be re-used because it was already heavily damaged from him having had diabetes and and alcoholism.
