According to the American Cancer Society, up to 35% of all cancer deaths may be prevented simply by following the suitable diet. For cancer prevention, cancer research institutes have recommended consuming at least five servings of fruits and vegetables per day, which should include any one of the cruciferous vegetables.
Generally, some of the above cruciferous vegetables, such as turnip, contain oxalic acid, which may crystallize as oxalate stones in the urinary tract. Hence, people with known oxalate urinary tract stones may have to avoid or minimize the intake.
