Pesto
Parmesan in pesto is an aged cheese — one of the highest direct sources of histamine — making it the main concern here.
Traditional pesto gets its rich, savory depth from Parmesan, which is a long-aged cheese and a significant histamine source.
-
Aged cheese — the longer a cheese ages, the more histamine builds up; Parmesan is aged for months to years, putting it at the higher end of the spectrum
-
Dairy and clearance — beyond the histamine in the cheese itself, many people with histamine sensitivity also report difficulty with dairy in general, which may compound the effect
Pesto made with a younger cheese like ricotta, or a dairy-free version, tends to be easier for sensitive individuals to assess.
