Targeting cancer stem cells, protecting DNA doesn’t even scratch the surface of what broccoli sprouts appear capable of. Here’s a sampling published just in one random month: anti-carcinogenic, anti-inflammatory, another anti-inflammatory, may protect against colorectal cancer, help fight cervical cancer. may protect against sunburn for goodness sake, and protect cartilage. And that’s just one month in the medical journals.
What’s the catch? There has to be a downside.
Well, in Turkey, recently, a report of liver toxicity thought due to juiced broccoli. 56 year old woman drinking about 3 and half cups of broccoli juice a day for a month.
A commentator balked at the assumption that that the broccoli juice per se was responsible for liver toxicity, suggesting that a more likely possibility is that the pesticide residue levels in such a large daily quantity of the vegetable were such that they adversely affected her liver cells. Three and a half cups of juice is like the equivalent of eating 18 cups of broccoli a day. 18 cups times 4 weeks. That’s 500 cups of broccoli. Even if it were organic broccoli, 500 cups a month is a lot of broccoli.
This was just a case report. Thankfully formal human toxicity studies have been done. Here for example they gave some volunteers a week of broccoli sprout extract equaling the sulforaphane content of about two dozen cups of broccoli a day and, no problems were found.

There is also the issue of the goitrogenic compounds in raw cruciferous. See my video Overdosing on Greens. We can also drink too much tea (seeOverdosing on Tea), eat too much of the spice turmeric (see Oxalates in Cinnamon), too much of the seaweed kelp (see Too Much Iodine Can Be As Bad As Too Little), and overdo coffee when pregnant (see Caffeine During Pregnancy). And that's just a smattering of the hundreds of other videos on more than a thousand subjects.
