Transcript: Broccoli: Sprouts vs. Supplements
Interest continues to grow about targeting cancer stem cells with a dietary component of broccoli, and especially broccoli sprout. Cancer stem cells are thought responsible for initiating and maintaining cancer, which I’ve talked about in the past.
There’s also been a number of randomized double-blind placebo-controlled clinical trials on the use of broccoli sprouts as a complementary treatment in diabetes, to reduce oxidative stress, reduce inflammation, and reduce insulin resistance and fasting blood sugars. In my video Biggest Nutrition Bang for Your Buck I describe how to grow your own simply and quickly in five days. New science suggests, though, that it’s even simpler and quicker than I described.
If you look at other sprouts, their antioxidant phytonutrients appear to peak around sprouting day five, up to 10-fold higher than day two, but the sulforaphane content in broccoli sprouts appears to peak at around 48 hours, so 2-day-old sprouts may be even better.
For consumers who do not enjoy eating broccoli, or broccoli sprouts, but still want the benefits of the broccoli phytonutrients, what about all of the different broccoli supplements on the market? Here they tested Broccomax, which boasts a half pound of broccoli’s worth in every capsule. They gave people six a day, compared to a cup of broccoli sprouts. Here’s the spike in broccoli phytonutrients in the bloodstream of those eating sprouts, which would cost about 25 cents a day, compared to six capsules of the supplement, which would cost about two dollars. They conclude that the bioavailability of broccoli phytonutrients is dramatically lower when subjects consume broccoli supplements compared to the whole food.
