This 2020 study used IPCC unscientific, politically-motivated, wild-ass guesses for year 2100 CO2 levels to find that broccoli sprouts – like most plants – benefit when CO2 is increased:
“Elevated CO2 (eCO2, 620 ppm, the expected IPCC-SRES B2-scenario prediction of eCO2 of the year 2100) was applied for 9 days to further improve nutritive and health-promoting values of three cultivars of broccoli sprouts.
- eCO2 improved sprouts growth and induced GLs [glucosinolates] accumulation.
- There were increases in myrosinase activity, which stimulated GLs hydrolysis to yield health-promoting sulforaphane.
- Low levels of sulforaphane nitrile were detected and positively correlated with reduced epithiospecifier protein after eCO2 treatment.
- High glucoraphanin and sulforaphane levels in eCO2 treated sprouts improved the anticarcinogenic and anti-inflammatory properties of their extracts.
In conclusion, eCO2 treatment enriches broccoli sprouts with health-promoting metabolites and bioactivities.”

This study was sponsored in Saudi Arabia. Would gathering such scientific evidence even be permitted in more “enlightened” countries?
Performing research on obvious lies and thinking for yourself isn’t allowed anymore in most “learning” institutions. You already knew that, didn’t you?
At the end of How much sulforaphane is suitable for healthy people? I applauded my high-school literature teachers for forcing their students to demonstrate that they could think for themselves. I didn’t mention that each monthly assignment to read two books, then compare-and-contrast them in a 3-page handwritten paper, was individualized so that students couldn’t undo the assignment’s purpose with parasitical collaboration.
This former practice remains a good measure of intentional dumbing-down of young people, the purpose of which has become clearer.
