Quorn: A Fungus Among Us

In the event you store for meat substitutes, you’ll have seen one thing within the freezer part known as Quorn (pronounced “kworn”). It’s the model identify for meals merchandise made with mycoprotein, derived from the soil fungus Fusarium venenatum. The fungus is fermented in vats and the ensuing paste is combined with egg whites and flavorings and formed into varied meat-like types, similar to burgers, cutlets and chicken-like nuggets. In comparison with different meat substitutes, it has a extra meaty texture and style.

Quorn is excessive in protein and fiber and is an effective supply of selenium and zinc. Entrepreneurs say it helps management ldl cholesterol, blood sugar and weight. Seems like an ideal vegetarian choice—nevertheless it has been the topic of a lot controversy.

What’s in a reputation?

Quorn was initially promoted as “mushroom in origin,” which sounds extra interesting than calling it a fungus. However mycoprotein isn’t a mushroom (not all fungi are mushrooms), and the American Mushroom Institute, the Middle for Science within the Public Curiosity (CSPI) and even another meals corporations took problem with the labeling. It’s now described as an edible fungus, like mushrooms and truffles—which, as opponents say, remains to be considerably misleading. And it’s hardly all pure, because it’s typically touted, since it’s extremely processed.

A matter of security

The Meals and Drug Administration (FDA) categorizes mycoprotein as GRAS, or typically acknowledged as secure. Nonetheless, greater than 1,500 antagonistic reactions have been reported to CSPI, together with extreme belly ache, vomiting, diarrhea and hives. A number of individuals have suffered respiratory difficulties and even anaphylaxis (a life-threatening allergic response). Not surprisingly, a mycoprotein web site lists a really low estimated threat of antagonistic reactions and says the commonest facet impact is simply flatulence, because of the fiber. CSPI is urging the FDA to revoke Quorn’s GRAS standing, or at the very least to require warning labels.

What concerning the well being claims?

A number of research, most from the early 1990s, counsel that mycoprotein could have optimistic results on ldl cholesterol, blood sugar and satiety. However they had been small, brief and infrequently flawed. The one current examine, a small company-funded one in 2010, urged a hyperlink between mycoprotein and improved ldl cholesterol—however this examine had issues, too. The potential well being advantages could also be because of the particular varieties of fiber in mycoprotein (beta-glucans and chitin).

Backside line: There are different meat alternate options, together with these constituted of soy, that don’t carry the chance of significant antagonistic reactions which have been reported from Quorn, until, in fact, you’re allergic to soy or their different components. Remember the fact that all processed meat substitutes, together with Quorn, are usually excessive in sodium and typically saturated fats from added cheese and different components.
