Here's proof that a cleanse can taste fantastic. Blueberries provide antioxidants to neutralize cell-damaging free radicals and contain quercetin, a pigment that may increase the number of enzymes in the liver. The banana's vitamin B6 helps recharge detoxifying enzymes throughout the body, and ground flaxseed or chia seeds supply additional fiber for healthy elimination (as well as brain-nourishing omega-3s).
