Soda pop can be a "bone robber." When I broke my ankle and had to have a plate and screws put in they told me at my age it would take 12 weeks or longer to mend, but the bone healed in 4. When they saw the X-Ray I went home in a walking cast instead of another plaster cast they said I would need. I attribute that to low-carb, high-fat, exercise and the herb Ginkgo Biloba to improve circulation.
