Well it can be trickier than you might think. The general advice is to get 30 grams a day. I tried that, and I ended up having to overeat by quite a bit to achieve that number. Then I realized that number was not meant for me, it was for men who are at least twice my size. I probably only need 15 grams a day, which I was probably already getting. But that "30 grams" recommendation is everywhere. There's also two different types of fiber, and you might need more of one than the other depending on your individual biome. I think most people would benefit from a more tailored recommendation or plan.

I also have a theory that fiber does not interact well with IBS, and that there may be some number of folks who don't know they have it. Personally, I can't digest leafy greens at all. I would eat them if I could, because it often feels like some personal failure and that I'm going to die early since I can't. But if the undigested bits get stuck in my intestinal pockets, I end up in the hospital. 🤷
