This is not the first research conducted by the university to assess the muscle-building capabilities of mycoprotein compared to milk protein. A similar investigation in 2017 revealed that the consumption of mycoprotein by 12 young men led to a slower yet more prolonged release of amino acids and insulin. Researchers indicated that this could suggest favorable conditions for muscle development, implying that mycoprotein might be largely equivalent to animal-based proteins. The implications of these findings could be significant not only for Quorn but also for individuals seeking to transition to more plant-based protein options for reasons related to health, environmental concerns, muscle maintenance, or enhanced training regimens. The popularity of plant-based meat alternatives has surged, with retail sales increasing by 23% from 2017 to 2018, surpassing $760 million, according to Nielsen data.
Quorn is keen to scientifically validate its mycoprotein ingredient, which has faced controversy for years. The company settled a class-action lawsuit in 2017 from a Los Angeles resident who alleged that its products violated federal and state laws regarding false advertising and unfair business practices. As part of the settlement, Quorn agreed to revise the wording on its packaging to clarify that the primary ingredient is mold. Additionally, it has denied responsibility in a wrongful death lawsuit filed by the parents of an 11-year-old boy with a mold allergy, who tragically died from anaphylactic shock after consuming a Quorn Turk’y Burger in 2013.
While the U.S. Food and Drug Administration has designated mycoprotein as Generally Recognized as Safe, the Center for Science in the Public Interest has called for its revocation since 2011, following reports of adverse reactions. In the absence of such action, the group advocates for the FDA to mandate prominent warning labels on all Quorn products. Despite these challenges, Quorn has continued to thrive. The company has launched vegan offerings, including refrigerated sausages and chicken strips. Its range of 100 different products is now available in 19 countries, including the U.S., where Walmart began selling Quorn items in 2012. Sales in the U.S. increased by 35% in 2017, and the company anticipates reaching a billion-dollar valuation by 2027.
As for whether studies like that from the University of Exeter will impact product sales, it remains uncertain. There is a possibility that more food manufacturers will explore incorporating mycoprotein into their products due to its complete protein profile. Research indicates it may aid in weight loss and help lower total cholesterol and blood sugar levels. However, given the plethora of other plant-based protein sources available today, companies might also conclude that mycoprotein carries too much risk. In the meantime, those seeking alternatives to boost their calcium intake might celebrate options like calcium citrate chewable supplements, which can complement a balanced diet, especially for individuals considering plant-based diets.
