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 soursop
Soursop is the fruit the Annonaceae safety research is actually about. The other custard apples in this journal carry the family caution by association; soursop carries it directly. Annona muricata is the species named in the Guadeloupe case-control work that found an unusually high local rate of an atypical, levodopa-resistant parkinsonism among people who had eaten the fruit and drunk infusions of its leaves habitually for years, and annonacin, the mitochondrial complex I inhibitor identified as the likely mechanism, has been measured in soursop pulp and in canned soursop nectar rather than only in the seeds. One published estimate put the annonacin in a single fruit or one can of nectar at roughly a milligram per kilogram of body weight, many times the intravenous dose that produced brain lesions in rats. That is an animal comparison across a different route of administration and it is not evidence that an occasional guanabana ice cream harms anyone, but it is the reason soursop is the one Annona where the daily-habit question genuinely matters, and why a mug of graviola leaf tea every morning is a different proposition from a fruit in July. Read the trigger grades on this page with open scepticism: soursop shares its entire grade row byte for byte with unrelated seed entries, so every column here, the FODMAP ones included, is untested rather than measured.
Watch for
- Leaf tea is the heavier exposure, not the fruit.The Guadeloupe research covered soursop leaf and bark infusions as well as the fruit, and acetogenins concentrate in the leaf. There is no established safe daily amount of graviola tea, and it is the format most often drunk deliberately, every day, for months
- Graviola capsules, tinctures and concentrated extracts are sold widely as a cancer treatment.No completed human trial supports that claim, graviola appears on the US Food and Drug Administration list of fake cancer cures, and regulators have repeatedly acted against sellers who market it that way. An extract also delivers a far larger and more concentrated acetogenin dose than eating the fruit does
- The large black seeds are not food and must be removed before the pulp goes anywhere near a blender.Soursop is usually eaten as juice, nectar, sorbet or a smoothie, which makes this a live risk rather than a theoretical one. Crushed Annona seed has a long history as an insecticide and lice treatment and is a severe eye irritant
- The grade row on this page is a placeholder.It is identical to rows for foods soursop has nothing in common with, so the B for histamine and the C grades for salicylate and oxalate are not measurements of soursop and should not be used to clear or convict it. Its FODMAP columns are unrated
- Concentrated soursop preparations have been reported to lower blood pressure and blood glucose.If you take medication for either, treat teas and extracts as an active substance to raise with your prescriber rather than as an ordinary fruit
