A new study has revealed how leafy greens like spinach absorb various toxic metals differently and offers strategies to reduce uptake, highlighting practical solutions for farmers, food processors, and consumers.
A recent, 8-year-long analysis of U.S. dark chocolate and cocoa products revealed a significant portion of samples to contain cadmium and lead levels exceeding California Proposition 65 maximum allowable limits, although concentrations of toxic heavy metals were seen to reduce over time.
Researchers from Tulane University assessed the levels and risks of
toxic metals in chocolates sold in the U.S., made from beans originating
from different global regions.
To protect the health of young children, the Baby Food Safety Act of 2024 has been introduced in U.S. Congress to give FDA the authority to enforce scientifically established limits on heavy metals in commercially produced infant and toddler food.
A recent study comparing the presence of chemical contaminants in conventionally and hydroponically grown produce found pesticide residues and toxic heavy metals in a larger number of conventional samples than in hydroponic samples. Phthalate levels were consistent between conventional and hydroponic samples.
Building upon a December 2022 report on the levels of toxic heavy metals in dark chocolate, Consumer Reports recently published new findings about the contaminants in other kinds of chocolates, suggesting that one-third of chocolate products contain high levels of heavy metals.
A U.S. Food and Drug Administration (FDA) study has estimated a toxicological reference value (TRV) for oral cadmium exposure. TRVs are useful in the development of action levels for contaminants in foods like toxic heavy metals.
The U.S. Department of Agriculture’s National Institute of Food and Agriculture (USDA’s NIFA) has granted a Michigan State University (MSU) research team $611,000 to explore the uptake of toxic heavy metals in food crops, with the goal of providing a guide containing mitigation strategies and decision-making resources for growers and policymakers.
In support of FDA's Closer to Zero initiative, researchers have conducted a risk assessment that estimates the U.S. population’s dietary exposure to cadmium. The study found children aged 6–24 months and 24–60 months to be the populations most highly exposed to cadmium, with concerning levels of exposure when compared to guidelines set by regulatory agencies.
A recent study published in Food and Chemical Toxicology suggests that lead, cadmium, and mercury have varying negative effects on human brain development and cognition.
