Just three meals a month eating raw cabbage or broccoli can reduce the risk of bladder cancer by up to 40%. Dark berries also have a proven role in the fight against malignancies.

The isothiocyanates contained in cabbage, cauliflower, broccoli, especially in non-smokers, have an incredible effect on the health of each of us. Researchers in New York have shown that non-smokers who eat more raw vegetables have a 73% lower risk of developing bladder cancer.

A similar study was performed in laboratory rats. When eating broccoli, the level of anti-carcinogens in the urine increases and this protects against malignant pathology.

A similar effect was found in Barrett's esophagus (presence of steel lining in the esophagus), which is considered precancerous, and the consumption of berries. The latter alter the excretion of substances that serve as markers of neoplastic degeneration.
