Most of the Vegetarian/vegan (including myself) i know tend to be at greater risk of mineral/Vitamin deficiency due to lack of nutritional knowledge. To minimize/eliminate the unnecessary risk , you should eat a wide variety of whole food diet ( that means no more refined carbohydrate like white rice ( take brown rice instead), white flour, noodle, pasta, soda, sugar and etc ). All of these refined food would only fill your body with mainly carbohydrate but little minerals and vitamin to help the actual metabolism and reproduction of body cell. Learning from those who have succeeded (like Erin and Steve) is also important before you get started . In addition, i would also suggest a vitamix/super blender as Steve talked about in another thread so you could make yourself a nutritious and delicious ice blend with various raw fruits and vege in it ( no sugar plz ). Finally, do not underestimate the importance of Methycobalamin B12 vitamin . Take my post as a grain of salt as i'm moving a little backward on the vegan thing ..
Additional note : Do not drink or cook you vege food with
RO, distilled water
