Can eating oysters while actively growing increase height?

This study suggests that this may be the case.

Taurine, a major amino acid of oyster, enhances linear bone growth in a mouse model of protein malnutrition.

“we evaluated the effects of Oys or Tau on linear bone growth in a mouse model of protein malnutrition{So there’s no guarantee that it will increase height in those who are not malnourished}. To make the protein malnutrition in a mouse, we used a low protein diet. Growth plate thickness was increased by Oys or Tau. Bone volume/tissue volume, trabecular thickness, trabecular number, connection density, and total porosity were also improved by Oys or Tau. Oys or Tau increased insulin-like growth factor-1 (IGF-1) levels in serum, liver, and tibia-growth plate. Phosphorylations of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 5 (STAT5) were increased by Oys and by Tau.  Oys or Tau may increase growth plate thickness by elevating IGF-1 levels and by promoting the phosphorylations of JAK2-STAT5, and suggest that Oys or Tau are growth-promoting substances of potential use in the food and pharmaceutical industries.”

“When a child is undernourished, circulating IGF-1, and thyroid hormone levels decline and in adolescents, undernutrition causes reductions in sex steroids, and these endocrine changes suppress bone growth “<-However this does not guarantee that overnutrition will stimulate bone growth.

“GH is required for linear growth, and its actions are initiated by its binding to GH receptor (GHR) on cell surfaces. This binding induces receptor homodimerization and activation of GHR-associated tyrosine kinase Janus kinase 2 (JAK2). JAK2 is then phosphorylated and, in turn, phosphorylates GHR and signal transducers and activators of transcription (STAT). Upon phosphorylation, STAT undergoes homo or heterodimerization, translocates to the nucleus, binds to appropriate DNA response elements, and stimulate the transcriptions of GH-regulated genes. IGF-1 is one such gene and acts as a mitogenic factor for various cells and plays an important role in cell growth and survival. The majority of plasma IGF-1 is biosynthesized in liver”

Unfortunately there was no group in this study that had adequate protein and had additional taurine supplementation.

“the mRNA expression of IGF-1 was dose-dependently increased. The effects of 100 µg/mL of Oys and 50 µg/mL of Tau were greatest, and thus, we evaluated the effects of these doses in our in vivo mouse model.”

” Mean lengths of proximal tibial growth plate in the CON and PEM groups were 115.64 ± 3.40 and 84.98 ± 2.70, respectively, whereas growth plate lengths in the Oys and Tau groups were 125.97 ± 8.07 and 123.05 ± 7.52, respectively. Oys or Tau significantly enhanced longitudinal bone growth”

Growth plate thickness was a little bit shorter in the oyster and taurine group versus the control group as were IGF-1 and GH levels.
