Top 10 Food Containing Nickel
Nickel is a mineral required in trace amounts in our body, as it is an integral part of many vital biological processes, and contributes to the production of hormones, lipids, and cell membranes. Dietary supplements to meet our minimal demands are unnecessary; intake of food containing nickel would suffice. Too much nickel intake can be toxic and can cause gastrointestinal distress, increased red blood cells, kidney stress, chronic bronchitis, reduced lung function, and lung cancer. Currently, no recommended daily intake for nickel is available, but the tolerable upper intake level of nickel is 1 mg among adults.
