These special supplements were continued for 35 weeks. In week 3, the rats were given an agent that causes tumors. There was a control group. Serum antioxidant capacity was measured in weeks 11 and 33. A strong preventive effect was observed in the group given spinach as it dietary supplement. Brussel sprout-fed rats had much more incidence of tumor, compared to the control group given what they called the basic Western diet. There are many similar studies.
