If i drink milk and eat yougourt and eat collard green speed up the recovery of a broken ankle and not way to eat i need it to heal in 6 to 8 weeks so month and two weeks i hope.?

No: It never hurts to eat healthy, but unfortunately the healing will take place in it's due time.

I don't believe: The healing in the bone will be substantially increased based on your diet. It is important that you are not deficient in say vitamin d and calcium but, once those levels are normal ...I don't feel "more is better". Bone takes 6-8 weeks. Things like smoking, steroids, even anti-inflammatories have all been reported to delay bone healing.
