Abstract

Background

Over the last decade, research has produced overwhelming evidence confirming the beneficial impact of vegan diet on health, as well as on implementation in the communicable disease prevention. Despite its various advantages, it may lead to nutritional deficiencies, which can have adverse effects on the human body.

Aim

The objective of this paper was to raise awareness of the potential risks associated with an imbalanced vegan diet during pregnancy and its impact on obstetric outcomes.

Methods

A comprehensive data analysis was conducted, focusing on the roles of nutrients that are often deficient in a vegan diet. The paper is based on a critical analysis of literature from databases such as PubMed, Google Scholar, Embase, Elsevier, and academic textbooks.

Findings

The analysis of scientific studies showed that during pregnancy, there is an increased demand for specific nutrients that are often deficient in a vegan diet (protein, individual amino acids, omega-3 polyunsaturated fatty acids, iron, calcium, iodine, zinc, vitamin D, and vitamin B12). Literature data confirmed that long-term cobalamin deficiency leads to serious health consequences such as: megaloblastic anemia, hyperhomocysteinemia and methylmalonic acidosis. Prevention of these disorders involves vitamin B12 supplementation.

Conclusion

A vegan diet can be safely followed during pregnancy if it is properly balanced and supplemented under the supervision of medical personnel. Nutritional deficiencies, particularly of vitamin B12, can negatively affect the course of pregnancy and obstetric outcomes.

素食对妊娠结局的影响

在过去的十年里，研究已经产生了压倒性的证据，证实了纯素饮食对健康的有益影响，以及在预防传染病方面的实施。尽管它有各种各样的优点，但它可能导致营养缺乏，这可能对人体产生不利影响。目的本文的目的是提高人们对怀孕期间不平衡素食饮食的潜在风险及其对产科结果的影响的认识。方法进行全面的数据分析，重点关注素食饮食中经常缺乏的营养素的作用。这篇论文是基于对PubMed、b谷歌Scholar、Embase、Elsevier和学术教科书等数据库文献的批判性分析。科学研究的分析表明，在怀孕期间，对纯素饮食中经常缺乏的特定营养素（蛋白质、单个氨基酸、omega-3多不饱和脂肪酸、铁、钙、碘、锌、维生素D和维生素B12）的需求增加。文献资料证实，长期钴胺素缺乏会导致严重的健康后果，如巨幼细胞性贫血、高同型半胱氨酸血症和甲基丙二酸中毒。预防这些疾病需要补充维生素B12。结论在医务人员的指导下，合理平衡和补充纯素饮食，是可以安全遵循妊娠期纯素饮食的。营养缺乏，特别是维生素B12缺乏，会对妊娠过程和产科结果产生负面影响。
