See earlier answer: Drink enough water daily so that your urine is mostly colorless. Take more fruit and may take fruit juice to ensure sufficient intake of potassium. Have a healthy diet, exercise 30 minutes/day, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine. Wish you good health!
