食物中的金属矿物质？——微量矿物质与合成维生素
摘要
许多商业食品，包括谷物麦片和婴儿食品，含有金属矿物质和合成维生素，而非天然植物来源的营养素。Berg 博士认为，plant-based minerals 与其金属形式或岩石来源的同类物质在健康价值方面存在显著差异。他通过一个简单的磁铁演示——将早餐麦片碾碎后靠近磁铁——直观地展示了常见”健康食品”中金属铁的存在。
核心要点
- 金属矿物质来源于岩石和地壳，与植物中所含的矿物质并不相同
- 植物能够从土壤中吸收金属矿物质，并将其转化为人体可利用的植物性形式
- 许多麦片、维生素补充剂和婴儿食品使用的是合成维生素和金属矿物质，而非植物来源的营养素
- 硫酸亚铁是加工食品中常用的一种金属铁形式
- 碳酸钙是补充剂和强化食品中使用的一种岩石来源矿物质的典型例子
- 强力磁铁能明显吸附从早餐麦片中碾出的金属铁颗粒，直观证明了其存在
- Berg 博士的观点是：植物性矿物质在人体健康方面优于金属矿物质
详细内容
矿物质本应如何发挥作用
据 Berg 博士介绍，自然过程是这样的：金属矿物质存在于土壤和岩石中，植物随后吸收这些矿物质，并将其转化为植物性形式，使人体更易消化和利用。这一转化步骤被认为至关重要——人类本应摄取经植物加工后的矿物质，而非原始的金属形态。
加工食品中实际含有什么
制造商——包括麦片品牌、维生素生产商和婴儿食品公司——正在绕过这一自然转化过程，直接在产品中添加：
- 金属铁（如硫酸亚铁）
- 岩石来源的钙（如碳酸钙）
- 合成维生素以及上述金属矿物质
这些成分常见于以营养丰富或有益健康为卖点的产品中。
磁铁演示实验
Berg 博士使用一块强力磁铁和从普通超市购买的早餐麦片进行了一项直观演示。碾碎的麦片明显被磁铁吸附，表明产品中存在真实的金属铁颗粒。这种铁与磁力产生响应，与普通金属铁无异——进一步印证了他的论点：添加到这些麦片中的铁是金属形态，而非植物来源的形式。
Berg 博士的立场
尽管以个人观点的形式表达，Berg 博士明确表示，他认为金属矿物质和岩石来源的矿物质并非人体健康的最佳选择，植物性矿物质更胜一筹。他对儿童常见食品（包括强化麦片和婴儿食品）中含有此类成分表示特别关切。

Metallic Nutrients In Food? – Trace Minerals and Synthetic Vitamins
Summary
Many commercial food products, including cereals and baby food, contain metallic minerals and synthetic vitamins rather than naturally occurring plant-based nutrients. Dr. Berg argues that there is a significant difference between plant-based minerals and their metallic or rock-derived counterparts in terms of health value. A simple magnet demonstration using crushed breakfast cereal visually illustrates the presence of metallic iron in commonly marketed “health foods.”
Key Takeaways
- Metallic minerals originate from rocks and the earth’s crust, and are not the same as the minerals found in plants
- Plants are designed to absorb metallic minerals from soil and convert them into bioavailable, plant-based forms for human consumption
- Many cereals, vitamin supplements, and baby foods use synthetic vitamins and metallic minerals instead of plant-derived nutrients
- Ferrous sulfate is a common form of metallic iron used in processed foods
- Calcium carbonate is an example of a rock-derived mineral used in supplements and fortified foods
- A strong magnet can visibly attract the metallic iron particles out of crushed breakfast cereal, demonstrating its presence
- Dr. Berg’s position is that plant-based minerals are superior to metallic minerals for human health
Details
How Minerals Are Supposed to Work
According to Dr. Berg, the natural process involves metallic minerals residing in soil and rock. Plants then absorb these minerals and convert them into plant-based forms that are easier for the human body to digest and utilize. This conversion step is considered critical — humans are meant to consume minerals in their plant-processed state, not in their raw metallic form.
What’s Actually in Processed Foods
Manufacturing companies — including cereal brands, vitamin producers, and baby food companies — are bypassing this natural conversion process. Instead, they are adding:
- Metallic iron (such as ferrous sulfate) directly into products
- Rock-derived calcium (such as calcium carbonate)
- Synthetic vitamins alongside these metallic minerals
These ingredients are frequently found in products marketed as nutritious or health-supporting.
The Magnet Demonstration
Dr. Berg performs a hands-on demonstration using a strong magnet and crushed breakfast cereal purchased from a standard grocery store. The cereal visibly clings to the magnet, showing that literal metallic iron particles are present in the product. This is the same type of iron that responds to magnetic force — reinforcing his argument that the iron added to these cereals is in a metallic, non-plant-based form.
Dr. Berg’s Position
While framed as his opinion, Dr. Berg clearly states his belief that metallic and rock-derived minerals are not the best option for human health compared to plant-based minerals. He expresses particular concern about these ingredients being present in foods commonly given to children, including fortified cereals and baby food.
