Regarding the results of bone parameters, the PTH obtained for vegans was at the cut-off level of hyperparathyroidism, which has been set at 65 pg/mL [40], and although there are no standardised cut-off values for BAP and NTx, the obtained BAP values are similar to those reported by Hansen et al. [35] in young vegan and vegetarians, and NTx levels are above [19] or similar to those found in previous studies on young women [34]. The gene discussed is PTH; the disease is hyperparathyroidism.
