Activist Mike Adams’ recent investigation found that rice protein imported from China had as much as 20 times the recommended limit for arsenic. Soil naturally contains elements that plants might absorb as they grow. Depending on many factors, including geographic region, the level of elements in soil varies. Unfortunately, heavy metals like lead, cadmium, tungsten, arsenic, and aluminum can be hazardous in large amounts or when consumed over time.
The USDA and FDA currently do not regulate the levels of heavy metals permitted in food or supplements. Only in the state of California is there legislation (Prop 65) that requires companies to label and measure risks associated with heavy metals. With these recent developments, the FDA is now considering whether a safety level should be set for arsenic in rice.
