#2 Broccoli & Broccoli Sprouts
Broccoli is a powerhouse food that contains many important phytochemicals. When you cook, chop, chew, and digest broccoli, it releases sulphorophanes called D-glucarate and indole-3-carbinol. These two substances are both known for their detoxification effects. Try adding broccoli sprouts to salads or sandwiches. The sprouts actually contain about 20 times as much sulfurophane as regular broccoli.
