Broccoli is a super food, not only is it nutritious it is a rich source of phytochemicals that increase your natural defenses against oxidative stress, and DNA damage.
Not surprisingly broccoli and other brassica vegetables have been shown to protect against a number of chronic diseases including some cancers.
So what happens when you eat broccoli. To find out a group of smokers (who already have high levels of oxidative stress and DNA damage) ate 250 g of steamed broccoli and were tested over the next 24 hours.
This is what the researchers found.
After 3 hours their:
Blood level of vitamin C increased by 35%
Blood level of folate increased by 70%
After 6 hours their:
Blood levels of β-carotene levels increased by 8%
Bodies antioxidant defense system (glutathione S-transferase) became activated.
And after 24 hours:
A significant reduction of the levels of oxidative stress (H2 O2) -induced DNA damage (-18%) occurred in a genetic subgroup of “broccoli responders.”
Something to think about next time you enjoy some broccoli; not only is it nutritious but activating your bodies defenses against DNA damage and disease for over 24 hours afterwards.
