Abstract

Selenium, an essential micronutrient known for its antioxidant and anti-inflammatory properties, has been extensively studied for its potential health benefits, especially in reducing oxidative stress and inflammation frequently observed in patients with noncommunicable diseases. The ongoing discussion about optimal selenium intake has led to two main approaches in scientific research: supplementation through selenium capsules and dietary intake via natural food sources such as Brazil nut (Bertholletia excelsa). Brazil nut is recognized as the richest known food source of selenium, with just one nut often fulfilling the Recommended Dietary Allowance of Selenium. However, while some studies support controlled selenium supplementation through capsules to ensure precise dosages, others emphasize the benefits of consuming whole foods like Brazil nuts, which also provide additional nutrients and health advantages. This narrative review investigates the ongoing discussion between these methods, highlighting the differences in bioavailability, potential health outcomes, and practical considerations for individuals. Capsule supplementation and dietary intake via Brazil nuts exhibit possible benefits; however, additional advantages connected to Brazil nut consumption have been noted. Further research is essential to determine the most suitable option for each specific noncommunicable disease and to address the complexities of dosage control, safety, and overall nutritional impact.

是不是巴西坚果？揭示慢性非传染性疾病硒的最佳来源

硒是一种以其抗氧化和抗炎特性而闻名的必需微量营养素，其潜在的健康益处已被广泛研究，特别是在减少非传染性疾病患者常见的氧化应激和炎症方面。关于最佳硒摄入量的持续讨论导致了科学研究中的两种主要方法：通过硒胶囊补充和通过天然食物来源如巴西坚果（Bertholletia excelsa）膳食摄入。巴西坚果被认为是最富含硒的食物来源，仅仅一颗坚果就能满足硒的推荐膳食摄入量。然而，虽然一些研究支持通过胶囊来控制硒的补充，以确保精确的剂量，但其他研究强调食用巴西坚果等天然食物的好处，这些食物还提供额外的营养和健康益处。这篇叙述性综述调查了这些方法之间正在进行的讨论，强调了生物利用度、潜在健康结果和个人实际考虑的差异。胶囊补充剂和通过巴西坚果摄入可能有好处；然而，人们注意到食用巴西坚果的其他好处。为确定每种特定非传染性疾病的最合适选择，并解决剂量控制、安全性和总体营养影响的复杂性，开展进一步研究至关重要。
