Why nickel food checker matters
Nickel is a metal found in many foods including chocolate, nuts, and leafy greens. People with nickel allergy (often showing as contact dermatitis) may also react to dietary nickel, causing skin and digestive symptoms.
- Avoid cooking acidic foods in stainless steel cookware
- Canned foods often have higher nickel content
- Chocolate, nuts, and legumes are common high-nickel foods
- First-draw water from taps may be higher in nickel - let it run
- Vitamin C may help reduce nickel absorption

What to know about avocado
Avocado is on almost every low-histamine avoid list, and unusually it earns the place twice: it grades high for histamine content and high as a histamine liberator, so it both delivers histamine and prompts your body to release its own. It is also high in salicylates and moderate in tyramine, which makes it one of the more amine-loaded fruits in an everyday diet. The FODMAP picture is narrower than the high grade suggests, because avocado is clean on fructans, GOS and excess fructose and clean for SIBO. Its entire FODMAP load is sorbitol, a polyol, which makes portion size the whole lever rather than an all-or-nothing decision. Two slices on toast and half a fruit in a bowl of guacamole are genuinely different exposures. Avocado oil is graded separately and carries none of this across.
Watch for
- High for histamine content and high as a liberator at the same time, a combination shared by only a handful of foods, which is why avocado shows up on low-histamine lists more consistently than most fruit
- Amine load climbs as the fruit over-ripens and after it has been cut and stored, so browning flesh and yesterday’s guacamole are the versions most likely to provoke a reaction
- The FODMAP problem is sorbitol alone.Fructans, GOS and excess fructose all grade clean and it rates well for SIBO, so tolerance tracks portion size closely and small amounts are often fine when a half fruit is not
- High in salicylates and moderate in tyramine, two separate triggers from the histamine story, which is worth knowing if avocado bothers you but other high-histamine foods do not
- Avocado cross-reacts with natural rubber latex, alongside banana, kiwi and chestnut, which is the usual explanation for itching or tingling in the mouth rather than anything histamine-related
- Moderate on nickel and only moderate for eosinophilic oesophagitis compatibility, so it is not automatically a safe fruit on either protocol
