Good and bad food for a nickel allergy

Nickel is a hard, silvery-white metal whose salts are present in all soils. Extremely small quantities of this element are required in the human body for optimal health but according to the MELISA Foundation, nickel consumption or exposure triggers more allergic reactions than any other element, and approximately 15% of the human population suffers from a nickel allergy.

Individuals can be exposed to nickel in a variety of ways, but most human contact is attributed to jewelry and food. Food? I hear you cry. Food? If you have a nickel allergy you will know that jewellery, watch straps, coins and almost anything metal in the home and workplace probably contains some nickel. Because it’s so hard it’s very useful to use mixed with other metals to produce a very durable end product. Great! but not if you are allergic to nickel.

Individuals who suffer from a nickel allergy should avoid foods rich in this element. (Ref Livestrong) But how do you know which foods contain nickel and why? I have tried to understand here for you why some foods are high in nickel content and others not. However just because you have a nickel allergy doesn’t mean you will necessarily react to these foods. But if you are still having skin problems it could be worth investigating these foods in your diet and noticing whether they make you worse or have no effect at all.

High content nickel containing foods – the ones to avoid!

  1. Chocolate/Cocoa Powder

    According to the Agency of Toxic Substances and Disease Registry, chocolate is one of the foods with the highest nickel content. Bittersweet chocolate contains a nickel concentration of 2.6 ug/g, milk chocolate has a nickel concentration of 1.2 ug/g and pure cocoa powder has a nickel concentration of 9.8 ug/g according to “Principles of Food Chemistry” by John M. deMan. The nickel content of chocolate is high due to the extensive refining process and constant contact with stainless steel machinery.

  2. Cashews

    Cashews also contain a relatively high concentration of nickel. The nickel concentration of cashews is 5.1 ug/g according to “Principles of Food Chemistry.” The World’s Healthiest Foods website states that consumption of cashews can yield some health benefits, such as the prevention of gallstones, promotion of cardiovascular health and maintenance of healthy bones and muscles.

  3. Kidney beans

  4. Kidney Beans

    Red kidney beans are another dietary source rich in nickel content.

    The nickel concentration of red kidney beans is 0.45 ug/g according to “Principles of Food Chemistry.”

  5. Green leafy vegetables

    Spinach contains high levels of naturally occurring nickel, 0.39 ug/g according to “Principles of Food Chemistry.” Also avoid other green leafy vegetables e.g. kale, lettuce

  6. Legumes especially dried beans and lentils.
  7. Bean sprouts also have a high nickel content.
  8. Whole wheat and multigrain flours are high in nickel content. Avoid wheat and oat bran, oatmeal, brown rice, and flower seeds (such as sunflower and sesame).
  9. Nuts almonds, hazlenuts and peanuts
  10. Seeds
  11. Soya
  12. Canned meats and fish, such as tuna.

  • Foods that you CAN eat on a nickel free diet

    • Fruits including peaches, pears, raisins, rhubarb, bananas, blueberries, strawberries, blackberries and other berries. Any of these can be eaten fresh or cooked, but not canned.
    • Most vegetables are allowed on this diet. Recommended vegetables include: bell peppers, cucumbers, eggplant, and cruciferous greens (cabbage, cauliflower, brussels sprouts, bok choy). Vegetables may be fresh or cooked; canned items are discouraged.
    • All plain dairy products eg. milk, cream, cheese, butter, yogurt etc. are allowed.
    • Grains: Refined wheat and most corn products are permitted on this diet. Pasta, white rice, cornflakes, cornmeal, and white breads are all low-nickel foods.
    • Most kinds of animal protein are low in nickel content. Chicken, turkey, beef, and eggs are recommended. Do not eat canned meats and fish, such as tuna.
    • Alcoholic beverages, coffee, and tea (though not from urns or machines) are allowed, as are sodas, and juices from low-nickel fruits.

    Some other suggestions:

    You could take a vitamin C supplement with each meal to slow the bodies absorption of nickel from the food you eat. If you also eat food rich in iron this could help too.

    “Don’t drink or use in food preparation the first quart of water taken from the tap because your pipes may release nickel.”

    “Replace nickel-plated utensils. You may use stainless steel pots and pans but avoid using them to cook acidic foods, which may cause pots and pans to release nickel.”

    Scientific studies into nickel in food

    Vegetables usually contain more nickel than do other food items; high levels have been found in legumes, spinach, lettuce and nuts. Certain products, such as baking powder and cocoa powder, have been found to contain excessive amounts of nickel, perhaps related to nickel leaching during the manufacturing process.

      Thank you Ruth for your helpful article. My daughter has just been diagnosed with nickel allergy and I did not know it existed, we are changing the way she eats and the way the whole family eats. She is just 5 years old and has had severe stomach pains for the past year. She ate beans every day and this was making her sick, but we had no idea. Articles like this helps us understand better what she can and cannot eat.

    2. Thanks for this although looking at this list it would just be better if I didn’t eat anything! What’s left when you cut out all of these things and most of them are healthy, too! Very depressing.

    3. It looks like you are remving almost everything but fruit and meats. Dark green veggies are very much needed in the diet.

      • Michael, recommendations for a low nickel diet is unfortunately not about nutrition. Greens and almost everything else contain levels of nickel harmful to people who have an allergy and hypersensitivity to it. This list is correct in that regard.

    4. I am vegan and I have a severe nickel allergy. I eat a lot of legumes. I have noticed a constant rash over my stomach and thighs. I don’t really enjoy a lot of the foods mentioned on a ‘nickel free’ diet. Will antihistamines control the rash or will I just have to live with it? I have never enjoyed meat, eggs or cheese and I hate aubergines.

      • Hi there Sarah, well the rash could be caused by anything but antihistamines may help relieve the itch. I would however be inclined to see if you can find out what is causing the rash. Is it any skin care products, washing powder, clothing, does it flare up when you’ve done certain things, or eaten certain things? You could try just reducing your legume intake or avoiding them for a week to see if the rash is related but it could have nothing whatsoever to do with it. It’s a long learning curve. Have you been to a dermatologist of consulted your doctor about it? It could be that you have eczema or other skin condition and some topical treatments may help clear it up. Good luck!

      • Hi Andrea, Oh I feel your pain, but you CAN get nickel free jewellery, it’s just more expensive #sodslaw and don’t panic too much. You may find some of these foods are OK for you. Experiment with eliminating and then reintroduce them carefully one by one to see if you see a change or reaction. Good luck! Will look a link to that nickel free jewellery for you. Good luck!

        • Hi, Andrea~

          I was also diagnosed with a nickel allergy around this time last year and had to quit wearing some of my older jewelry. I just found a jewelry company and decided to work for them because I liked their concept. All of their jewelry is nickel free, lead free & hypoallergenic. I love that I’m able to wear it without breaking out. You can check out my link to my boutique where you can find some of my favorite picks or checkout the whole gallery~ Let me know if you have any questions! Hope this was helpful~ =)
