Eating broccoli appears to make DNA more resistant to damage.
DNA Protection from Broccoli, 5.0 out of 5 based on 2 ratings
The best way to study DNA repair is to study smokers, because they need a lot of it. A group of smokers, for a total of ten days were asked to eat 6 times more broccoli than the average American consumes. In other words… a single stalk.
Compared to smokers not eating broccoli, those who did suffered about 30% less DNA damage over those 10 days. Maybe it was because the broccoli boosted the detoxifying enzymes in their livers and so the carcinogens never made it to their DNA?
Well they tested for that. They actually took some DNA out of their bodies, put it into a test tube and exposed it to a known DNA-damaging chemical. The DNA of broccoli eaters suffered significantly less damage; the DNA of those eating broccoli appears intrinsically was more resistant at a subcellular level.
In conclusion, in the present study, the intake of broccoli seems protective, as far as DNA damage is concerned, in smokers who are exposed to oxidative stress.

This discovery may help explain the findings I presented in Repairing DNA Damage. What about giving smokers kale? See yesterday's video Smoking Versus Kale Juice. There are 19 other videos about DNA damage and hundreds of other videos on more than a thousand subjects.
