Been thinking about measurements made in Switch on your Nrf2 signaling pathway where a maximum beneficial dietary intake was 800 grams non-starchy plant foods, whereas my intake was 1,279.5 grams. That led to analysis of top non-starchy fiber constituents:

Informed by It’s the fiber, not the fat findings that dietary soluble fiber had large effects, it seems that I could remove ≈ 450 grams (1 lb.) of celery and summer squash that makes only a 1.6 gram contribution toward soluble fiber.

I’m not concerned about other contributions of celery and summer squash, because I get their nutrients elsewhere anyway. I may add celery seed to my twice-daily AGE-less Chicken Vegetable Soup meal for taste.

I plan to replace this 1.6 g soluble fiber / 450 g total fiber with prebiotic chicory root inulin of ~ 3 g soluble fiber / 10 g total fiber. Will update in two weeks. See Increasing soluble fiber intake with inulin.
