To complement Parts 1 and 2, an informative and detailed video:

My daily intake includes most of what’s mentioned in the video. For example, sulforaphane and other beneficial broccoli sprouts compounds, twice a day through 65.5 g of three-day-old broccoli / red cabbage / mustard sprouts microwaved to 60°C. And capers – a high source of quercetin (but see comparisons starting at 31:00, 80% vs. 4% bioavailability) – after soaking and rinsing them several times to reduce sodium content.

I arrived at this video via Dr. Houghton’s paper https://www.researchgate.net/publication/355201137_The_COVID_’Vaccine’_Dilemma_-_a_mechanistic_hypothesis “The COVID ‘Vaccine’ Dilemma – a mechanistic hypothesis” (registration required) posted yesterday.
