Researchers at the University of Illinois conducted a study and found that adding horseradish or wasabi to broccoli as a seasoning during cooking activates its anti-cancer properties. They contain the enzyme myrosinase, which helps the beneficial substances of broccoli be absorbed into the upper part of the digestive tract. Scientists also noted: the spicier the seasoning, the healthier it will be. If you can't stand spicy food, then combine broccoli with radishes, cabbage and watercress - they can also activate the anti-cancer properties of the former. Seasoned broccoli should be consumed five times a week to minimize the occurrence of cancer.
