■素食主义的日益流行决定了需要全面研究这些饮食对健康,特别是骨骼代谢的影响。我们假设素食主义者之间的饮食差异很大,乳卵素食者,杂食动物也会导致其营养状况的显着差异,这可能会影响骨骼健康。
■该研究评估了腰椎和股骨颈的双能X射线吸收测量参数,平均营养素摄入量,血清营养素浓度,血清PTH水平,46名素食者的尿液pH值,38名乳卵素食者,和44个杂食动物。
■两组之间的骨矿物质密度(BMD)没有差异。然而,与杂食动物相比,纯素食者的甲状旁腺激素(PTH)水平仍然更高,尽管所有组甲状旁腺功能亢进的患病率相同。这些发现可能是因为每个小组都有自己的“优势和劣势”。\"因此,素食主义者和,在较小程度上,乳卵素食者消耗更多的钾,镁,铜,锰,和维生素B6,B9和C。杂食动物的饮食含有更多的蛋白质和维生素D和B12。所有受试者消耗的维生素D比推荐的少。超过一半的素食主义者和杂食动物血液中维生素D不足甚至缺乏。锰的低血清浓度及其足够的摄入量也值得注意:在57%的素食主义者中观察到锰的缺乏,79%的乳卵素食者,和63%的杂食动物。
■目前,不再可能得出乳卵素食者的BMD低于杂食动物的结论,我们的研究支持。我们研究中的素食者也没有表现出较低的BMD值,只有更高的PTH血液浓度,与杂食动物相比,然而,大量的研究,包括最近,显示相反的观点。在这方面,需要进一步的大规模研究。素食主义者和乳卵素食者现在有各种富含维生素D和B12以及钙的食物。道德来源的膳食补充剂也有很大的多样性。发现的低浓度锰需要进一步研究。
UNASSIGNED: The growing prevalence of vegetarianism determines the need for comprehensive study of the impact of these diets on health and particularly on bone metabolism. We hypothesized that significant dietary differences between vegans, lacto-ovo-vegetarians, and omnivores also cause significant differences in their nutrient status, which may affect bone health.
UNASSIGNED: The study assessed dual-energy X-ray absorptiometry parameters in lumbar spine and femoral neck, average nutrient intake, serum nutrient concentrations, serum PTH levels, and urinary pH among 46 vegans, 38 lacto-ovo-vegetarians, and 44 omnivores.
UNASSIGNED: There were no differences in bone mineral density (BMD) between the groups. However, the parathyroid hormone (PTH) levels were still higher in vegans compared to omnivores, despite the same prevalence of hyperparathyroidism in all groups. These findings may probably be explained by the fact that each group had its own \"strengths and weaknesses.\" Thus, vegans and, to a lesser extent, lacto-ovo-vegetarians consumed much more potassium, magnesium, copper, manganese, and vitamins B6, B9, and C. At the same time, the diet of omnivores contained more protein and vitamins D and B12. All the subjects consumed less vitamin D than recommended. More than half of vegans and omnivores had insufficiency or even deficiency of vitamin D in the blood. Low serum concentrations of manganese with its quite adequate intake are also noteworthy: its deficiency was observed in 57% of vegans, 79% of lacto-ovo-vegetarians, and 63% of omnivores.
UNASSIGNED: Currently, it is no longer possible to conclude that lacto-ovo-vegetarians have lower BMD than omnivores, as our research supported. Vegans in our study also did not demonstrate lower BMD values, only higher PTH blood concentrations, compared to omnivores, however, a large number of studies, including recent, show the opposite view. In this regard, further large-scale research is required. Vegans and lacto-ovo-vegetarians now have a variety of foods fortified with vitamins D and B12, as well as calcium. There is also a great diversity of ethically sourced dietary supplements. The found low concentrations of manganese require further investigation.
