Nickel-Low Foods for Dyshidrotic Eczema
Lower-nickel choices for people whose pompholyx is diet-linked. A starting list of lower and higher nickel foods, plus the cookware, canned-food and tap-water points that often get missed.
Read this first
A low-nickel diet only makes sense for people with a confirmed nickel allergy whose pompholyx or hand eczema keeps flaring without a contact explanation. It is not a general eczema diet, and it cuts out several healthy foods, so it should be a short, supervised trial rather than a way of life. Nickel content varies with soil and processing, so treat any list, including this one, as approximate. Before you start, the nickel allergy should be confirmed, usually by patch testing arranged through your GP or a dermatologist.
This page is educational and is not medical advice. Dietary nickel is only ever part of the picture, and most people with a nickel allergy react mainly to contact rather than food, so professional guidance matters.
Foods that tend to be lower in nickel
As a starting list for a supervised trial, these tend to sit lower:
- Fresh meat, poultry and most fish
- Eggs and dairy
- Refined white grains and many breads made from them
- Certain vegetables, such as cucumber, carrot and most salad leaves
- Coffee and tea, in moderation
Refined grains are lower than wholegrains here, which is the opposite of the usual healthy-eating advice, and one reason a low-nickel phase should be short and supervised rather than permanent.
Foods that tend to be higher in nickel
These are the foods a low-nickel trial usually reduces:
- Legumes, including beans, lentils, peas, soya and soy products
- Oats and wholegrains
- Nuts and seeds
- Cocoa and chocolate
- Canned foods, since nickel can leach from the can
- Some shellfish
Many of these are otherwise nutritious, which is exactly why blanket, long-term avoidance is a poor idea and a dietitian’s input is worth having.
The points people miss
Nickel does not only come from food itself. Three things often get overlooked:
- Cookware: acidic foods cooked in old or cheap stainless steel can pick up nickel, so use good-quality or non-stainless pans for tomato-based dishes
- Water: running the tap for a few seconds before use can lower the first-draw metal content
- Cans: choose fresh, frozen or jarred foods over canned where you can, since canning can add to the nickel load
These small changes sometimes make more difference than swapping individual foods, because they affect a lot of meals at once.
How to run a trial safely
Rather than avoiding nickel forever, the sensible approach is a short, structured trial. Lower your dietary nickel for a limited period with a dietitian’s guidance, keep a food and skin diary alongside notes on contact exposures, then reintroduce foods gradually to find your threshold. Because pompholyx has several possible triggers, a diary that records both what you ate and what you touched helps separate a diet link from a contact one, which is often the real driver.
A note on getting it right
Because this diet removes legumes, wholegrains and nuts, get a dietitian’s help to keep it balanced, and reintroduce foods to find your threshold rather than restricting indefinitely. Confirm the nickel allergy with patch testing first, so you are not cutting out healthy foods for a trigger you do not actually have. If your hand eczema is severe or persistent, your GP or dermatologist can review treatment as well as the possible dietary angle.
Check products against your list
A free database like Open Food Facts lets you look up a product’s ingredients, and Fig is genuinely good for running a defined eating pattern such as a low-nickel trial. These give broad information rather than a check against your own skin. To check a product against the specific things that make your skin react, a personal-list app like ClearaScan lets you save your triggers once and scan any product, food, medication or cosmetic, against your ingredient guard list, flagging only yours. Its Reaction Journal lets you tie a flare back to the product that caused it, a shared Care Circle lets family scan for you, and a Trusted Products list keeps what you have cleared. It is currently in early access. (Disclosure: our editor co-founded ClearaScan, and we are not paid to mention the others.)

Common questions
Who is a low-nickel diet actually for?
It only makes sense for people with a confirmed nickel allergy whose pompholyx or hand eczema keeps flaring without a clear contact explanation. It is not a general eczema diet, and it should not be started without confirming the allergy, usually through patch testing.
Which foods tend to be lower in nickel?
Fresh meat, poultry and most fish, eggs and dairy, refined white grains and breads made from them, certain vegetables such as cucumber and carrot, and coffee and tea in moderation tend to sit lower in nickel.
Which foods are higher in nickel?
Legumes such as beans, lentils and soya, oats and wholegrains, nuts and seeds, cocoa and chocolate, canned foods, and some shellfish tend to be higher. Nickel content varies with soil and processing, so treat any list as approximate.
Do cookware and cans really matter?
Yes. Acidic foods cooked in old or cheap stainless steel can pick up nickel, canned foods can absorb nickel from the can, and the first water drawn from a tap can carry more metal. Choosing fresh or frozen over canned and running the tap briefly first can help.
Should I try this diet on my own?
No. Because it removes legumes, wholegrains and nuts, it should be a short, supervised trial with a dietitian to keep it balanced, and the nickel allergy should be confirmed by patch testing first. See your GP or dermatologist before starting.
