Polyphosphates (E452)
Caution
May cause symptoms in more sensitive people. Track your own reaction.
Although polyphosphates (E452) are not a direct source of histamine, they are not ideal for a histamine diet. The recognized SIGHI list places them in Category 1, which means that even in small amounts they can cause mild symptoms or be poorly tolerated by more sensitive individuals. It is therefore better to avoid them during a strict diet.
