unique types of antioxidants, nutrients, and natural cancer fighters, so a wider variety exposes your body to a broader spectrum of protection.

of cardiovascular diseases (2) improved regulation
of blood sugar, with decreased risk
of type 2 diabetes, and (3) prevention
of certain cancer
types including breast, cervical, colon, and esophageal cancer.»
