I have been asked that question regularly for more than 30 years. This may be a reflection of the general population's scientific illiteracy, but most people remain hazy about the composition of Quorn - even those who eat it regularly. However, many of us are prepared to accept this understanding gap because Quorn seems to be on the right side of the prevailing food paradigm, which holds that eating meat, fish, dairy and eggs is a redneck habit that has had its day, one that amounts to propagating cruelty and environmental ruin and will lead to dire consequences for human health.
