Frequently asked questions

Which intolerances does nitre affect?

nitre is notable for Histamine.

Does nitre contain Histamine?

nitre contains moderate levels of Histamine. Nitrites and nitrates (E249-252) matter less for what they do than for where they are: they are the curing salts of ham, bacon, salami and chorizo — foods whose histamine is built by the curing itself. The additive is a marker of a high-histamine process more than an independent trigger. Sources: Comas-Basté et al., Biomolecules 2020; EFSA re-evaluation of nitrites and nitrates, 2017. Amounts vary by brand and recipe, so always check the label of the exact product.
