Tag: Systemic nickel allergy syndrome

For those with nickel sensitivity, an average diet can supply a significant amount of the mineral, potentially triggering a reaction. Avoiding foods with high nickel content and choosing lower-nickel options is a primary way to manage this condition, although truly 'nickel-free' foods are nearly impossible to find due to its natural presence in soil.

According to a 2025 study from Eurofins, cashew nuts have one of the highest concentrations of nickel among all tested foods, measuring 5.4 mg/kg. This fact is critical for individuals asking, "do cashews have nickel?" as this ubiquitous trace metal is a common allergen that can cause systemic reactions.

For those with systemic nickel allergy syndrome (SNAS), studies have shown that a low-nickel diet can significantly improve chronic dermatitis symptoms. However, the exact duration of a low nickel diet depends on a patient's individual response, symptom severity, and medical supervision.

Approximately 8-19% of the population in Europe has a nickel allergy, and for some, ingesting foods high in nickel can cause a systemic reaction. For sensitive individuals, understanding what happens when your diet is high in nickel is crucial for managing symptoms that can range from skin rashes to gastrointestinal distress.

Trace amounts of nickel are found naturally in coffee, absorbed from the soil and water where coffee plants grow, as is common with many plants. For the vast majority of people, this is not a concern, but for individuals with a high sensitivity to nickel, the question, **"Does coffee have a lot of nickel?"** becomes a critical dietary consideration.

While cinnamon is widely celebrated for its health benefits, for individuals with Systemic Nickel Allergy Syndrome (SNAS), understanding its nickel content is vital to prevent adverse reactions. So, is cinnamon high in nickel, and how should it be managed in a low-nickel nutrition diet?

While traces of nickel are found in most natural foodstuffs, including soil, water, and the air, coffee can also contain detectable amounts. The key question for many is: **Is nickel in coffee?** The answer involves understanding both the plant's absorption from soil and how processing and brewing methods might affect the final cup.
