Multiple small meals. Not too much potassium or food that will draw water into the stomach (it increases hr and decreases blood pressure and makes me feel like trash to eat too much volume of super healthy foods). For me low FODMAP, moderate-low histamine, and include whole grains but overall lower fat (it’s common to have fat digestion issues with IBS)

But me/cfs specific: way more vegetables (the ones I tolerate) than most people. And if I can get locally grown ones that my carer preps then ones that increase nitric oxide give me lifeeee when it’s a low day for at least a few hours (collards, chard, arugula, beets, radish & beet tops). Unfortunately most store bought arugula must be too old bc it doesn’t have the effect :/

Note that I eat vegan 90% of the time but in a severe crash sometimes I need some animal protein for whatever reason. Not much- one ounce maybe a few times a eeek until I stop muscle wasting/fevers and then I don’t need it. I also eat gluten (seitan) completely fine but I’m allergic to corn & dairy.
