概括
植物性蛋白质补充剂 (PS) 提供必需的营养素,但可能含有潜在的有毒元素 (PTEs). 虽然在推剂量下通常是安全的,但过量摄入这些素食补充剂可能会超过营养限制.
科学领域:
- 食品科学 食品科学 食品科学
- 营养生物化学 营养生物化学
- 环境健康 环境健康
背景情况:
- 越来越多的植物性饮食需求需要植物性蛋白质补充剂 (PS) 等营养补充剂.
- PS对于素食主义者和素食主义者来说至关重要,但可能含有潜在的有毒元素 (PTEs),造成健康风险.
- 评估PS的元素组成对于消费者安全和营养指导至关重要.
研究的目的:
- 在商用植物性蛋白质补充剂中量化基本元素和PTE.
- 评估与不同摄入水平消费这些补充剂相关的饮食暴露风险.
- 为了将估计的摄入量与已确定的参考值进行比较,并计算的暴露率 (MOE).
主要方法:
- 分析了来自欧洲的56个植物性PS样本.
- 使用诱导合等离子光学发射光谱法 (ICP-OES) 量化金属.
- 基于三个消费场景和确定的参考摄入值 (AI/TDI/TWI/UL) 的饮食暴露评估.
主要成果:
- PS富含,和等基本元素,但也含有包括,和在内的PTE.
- 在每天30g的建议摄入量下,对大多数元素的暴露不会超过安全限值,尽管摄入量达到AI的75%.
- 过度摄入 (100克/天) 导致女性的铜和,男性和绝经后妇女的和铁的充足摄入量 (AI) 水平超过.
结论:
- 植物性蛋白质补充剂是必需营养素和潜在的有毒元素的重要来源.
- 目前推的摄入量似乎是安全的,但过量摄入会导致营养需求的超出.
- 消费者应该意识到植物性蛋白质补充剂的双重营养和毒理特征.

636
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
