Transcript: Carcinogenic Putrescine
I’ve talked in the past about the biogenic amines like spermine and cadaverine that can be formed in decomposing tissues, but a new review on the human toxicological effects of these substances in our diet suggests that putrescine may have carcinogenic-cancer causing effects.
Putrescine is a chemical compound of decay that contributes to the smell of putrefying flesh and the fishy odor of certain vaginal infections. But it’s found even in non-spoiled fish, meat, cheese, and fermented foods. You can’t stay away from it, though, unless you know which foods have the most.
Here’s a dozen commonly eaten foods they tested: beer, blue cheese, feta cheese, canned tuna, sardines, sauerkraut, sausage, soy sauce, kimchi, miso, tempe, and wine. Which do you think has the most? Sardines were the runner-up, but the highest levels are found in tuna.
To stay away from putrescine, we should stay away from canned fish.
There’s a recommendation that we should try to stick under 40 mg in a meal. So just a couple bites, a quarter of a serving of tuna and we’re over the limit, but it would take two servings of sausages or like ten beers to approach the limit otherwise.
