What happens to your body after you eat broccoli?

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.
