🔬 **蛋白质粉铅含量普遍超标**：一项针对23种热门蛋白质粉和奶昔的研究显示，超过三分之二的产品每份含有的铅量高于专家建议的每日安全摄入量，部分产品甚至达到每日安全水平的1200%-1600%。

🌿 **植物基产品铅含量尤为突出**：研究指出，植物基蛋白质粉的铅含量平均是乳制品基蛋白质粉的九倍，其中两款产品（Naked Nutrition的"Vegan Mass Gainer"和Huel的"Black Edition"）因铅含量过高，被专家建议消费者完全避免食用。

⚠️ **日常食用存在健康风险**：即使是乳制品基的蛋白质产品，也有半数产品的铅含量不适合日常食用，这表明即使是看似更安全的选择也可能存在潜在的健康隐患。研究人员表示，对于许多人来说，食用这些产品弊大于利。

📜 **监管滞后与消费者担忧**：美国食品药品监督管理局（FDA）不对蛋白质粉进行上市前审查，这意味着消费者在购买时无法获得官方的安全性保障。此次研究结果比15年前的检测结果更差，凸显了现有监管的不足以及消费者对产品安全性的担忧。

📈 **高蛋白产品市场增长下的隐忧**：随着高蛋白产品因其支持肌肉修复、免疫功能和新陈代谢的益处而日益受欢迎，此次研究揭示了市场增长背后可能存在的食品安全问题，提醒消费者在追求健康益处的同时，也需关注产品成分的安全。

A new study shows some popular protein powders and shakes lining grocery store shelves contain unsafe amounts of lead, with several products far exceeding what experts say is safe to consume in a single day. 

Researchers recently tested 23 top-selling protein powders and ready-to-drink shakes and discovered more than two-thirds contained more lead per serving than experts consider safe for daily consumption, according to Consumer Reports.

"For many people, there’s more to lose than you’re gaining," Tunde Akinleye, the Consumer Reports food safety researcher who led the project, said.

Plant-based powders were among the worst offenders, containing nine times more lead on average than dairy-based options like whey.

Two protein powders, Naked Nutrition’s "Vegan Mass Gainer" and Huel’s "Black Edition," had so much lead that experts warned consumers to avoid using them entirely. 

A single serving reached between 1,200 and 1,600 percent of Consumer Reports’ level of concern for lead.

While the dairy-based powders that were tested typically had lower levels, half still contained enough lead to make daily use unsafe, according to Consumer Reports.

"It’s concerning that these results are even worse than the last time we tested," Akinleye said.

The new report comes 15 years after Consumer Reports’ previous test in 2010. At the time, more products had undetectable levels of lead, according to the nonprofit.

The Food and Drug Administration (FDA) does not review, approve or test protein powders before they hit store shelves.

Over the past year, high-protein grocery items have surged in popularity, with shoppers seeking products that support muscle repair, immune function and metabolism. Even Starbucks recently announced it was "going all-in on protein" with the arrival of its Protein Lattes and Protein Cold Foam.
