Cancer fighting cheap food that you can add to your salad

Watercress delivers a powerful punch of excellent nutrients you need in abundance every day: calcium, vitamin C, folate, iron, lutein, beta-carotene, potassium, and phenylethyl isothiocyante.
Um…phen what what?
Please don’t feed the tumors
We’ll call it PEITC for short. Cruciferous vegetables such as watercress are rich in this chemical compound that inhibits the activation of a protein known as HIF. Cancer cells use HIF to create small blood vessels that feed tumors. So if you block HIF effectively, cancer cells can’t invade normal tissue.
In new research from the University of Southampton, several breast cancer survivors were asked to fast, then eat 80 grams of watercress (about enough to fill a cereal bowl). Blood was drawn from each subject before, during, and after the intervention.
Results showed a significant boost in blood levels of PEITC after eating watercress. Most importantly, the HIF function was “measurably affected.”
Now–hold those good thoughts while we look at another watercress study conducted several years ago at Ireland’s University of Ulster.
Sixty healthy adults ate 85 grams of raw watercress along with their regular daily diets. Before and after the eight week trial, researchers measured several biomarkers related to cancer risk.
Results: Antioxidant levels were significantly boosted. Triglycerides dropped by 10 percent. And DNA damage to white blood cells dropped by more than 20 percent.
