Aims:
- 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.
- To determine the influence of urinary calcium excretion on the predictability of changes in bone metabolism from acid and base precursors in the diet.
- 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.

Description:
Evaluation of data from this experiment will provide insight into the role of animal protein and potassium (and related factors) on bone loss during spaceflight. These data will lead to better defined nutritional requirements and will help guide food development for future missions.
This task contributes to N7.1 by identifying significant elements of diet or nutritional status that impact measures of musculoskeletal health.
This task contributes to N13 by evaluating dietary intake data in light of renal stone risk profiles.
