What ever you do, do not consult a regular doctor they know nothing about preventive health or nutrition, the best thing you can do is eat raw veggies, drink raw milk, eat lean meat such as chicken and fish, drink at least a gallon of water a day, take at least 8,000 mg of vitamin c and flax oil (dynamically mind you) find a nice clean whey protein isolate that is NON denatured and most importantly:
Workout and train like a beast every day!!!!!!
