Short Title: Pro-K
Responsible HRP Element: Human Health Countermeasures
Collaborating Org(s):
Funding Status: Completed - Task completed and produced a deliverable
Procurement Mechanism(s):
  1. To determine if the ratio of acid (animal protein) to base (potassium) precursors in the diet is correlated with markers of bone formation and bone resorption during spaceflight.  Specifically, this aim will be addressed by controlling the ratio of animal protein to potassium intake during short-duration spaceflight.
  2. To determine the influence of urinary calcium excretion on the predictability of changes in bone metabolism from acid and base precursors in the diet.
  3. To determine if the ratio of acid to base precursors in the diet is related to length of time required for recovery from bone mineral loss after spaceflight.  This aim will be addressed during recovery from long-duration spaceflight. 

Integration/Unique Aspects: Informs multiple disciplines and future work in nutrition.
