                                According to studies, plant-based foods, particularly legumes and nuts, are often among the highest in nickel content due to the metal being absorbed from the soil during growth. This can be a significant concern for individuals with a nickel allergy or systemic nickel sensitivity, where ingesting foods with high levels of this metal can trigger adverse reactions.
