I’m having stone-aged internet issues this week which is really impeding my responses and testing my patience! LOL You posed a really great question so I’m happy to see @athenalee pop in with answers because I was going to tag her into this conversation! She’s a guru when it comes to health and well-being of our bodies through foods in our diets!

A while back I discussed this with my transplant team. What can be done to avoid GvHD of the liver (and in general) The only GvHD I have right now is a slight indication of “potential” liver issues because of minor elevations in my liver function numbers, similar to yours.
A lot of our GvHD is simply hit and miss. It’s whatever our immune system decides needs fixing and starts these ‘little fires’ in our bodies that have to be stomped out with prednisone or other anti inflammatory meds. So whatever we can do to avoid inflammation is one proactive thing we can do to avoid getting those new cells all riled up…such as avoiding any illness, avoiding sun, toxins, etc.

There are some research discussions regarding Choline in the diet. It’s being studied for potential issues within the gut biome which can cause inflammation, which in turn may cause GvHD. But it’s not proven and most of these foods on the Choline list are more important to our overall health than any speculation.
They include eggs, fish, beef, soybeans, wheat germ, chicken, turkey, cruciferous veggies, almonds, dried beans, cottage cheese…you get the picture!

So, the talk with my team focused more on what foods are GOOD for the liver rather than avoiding the Choline rich foods. And because some of the good foods contain choline, it’s really a matter of keeping a healthy body through diet, exercise and water intake.

There are liver specific foods which help promote the health of the organ.
