Last night I was watching TV and one of those Smart Buy ads
popped up, advertising Quorn products. According to the commercials, this
product range provides a meat-free, soy-free solution to meatless meals. I have
never heard of this brand, so I decided to do some investigation on whether
this product is any good and what are the pros and cons, as I think its
important to understand a food before eating or recommending it to patients!
So what is the Quorn meat-free and soy-free solution? Quorn
uses a product called Mycoprotein – a microscopic fungus, Fusarium venenatum, which the company feeds with oxygenated water,
glucose, and other nutrients in giant fermentation tanks. Once harvested from
the tanks, the material is heat-treated in order to remove its excess RNA, and
then dewatered in a centrifuge. Combined with egg albumen and other
ingredients, it is then “texturized” into various meat-like shapes. mmmm, sounds tasty already!
Quorn prides itself on the fact that you will not be able to
taste the difference between meat and their products – the texture and taste
are almost identical to meat, without the saturated fat.
A little bit more about Mycoprotein. Heres the nutritional

As you an see, its low in sodium and is a good source of
complete protein, zinc and fibre. The phosphorus seems a little high – the Australian
recommended daily intake (rdi) is 1000mg, however it is stated that doses of
over 250mg at one time may cause stomach irritation in some individuals. Note
that this is also an amount per 100g – some people have more than 100g, some
have less, so your nutrient intake may differ.
So mycoprotein doesn’t seem too bad by itself. However,
Quorn processes their mycoprotein for their foods and it is NOT the only
ingredient in their products. Some products contained high amounts of mycoprotein
(up to 90%), but some ready-made Quorn meals only contained 11% mycoprotein. So
what makes up the rest? Here are some the ingredients I found that stood out:
- Rehydrated egg whites: This is powdered egg
white, but should be noted for anyone who has an egg allergy.
- Autolyzed yeast extract: Autolyzed yeast extract is a substance that results when
yeast is broken down into its constituent components. It contains some free
glutamic acid or monosodium glutamate (MSG) and is used as a less expensive
substitute for MSG, leading some health and consumer advocates to object to its
use in foods. As with MSG, the industry claims that yeast extract is a natural
substance with no harmful effects, and opponents claim it causes a variety of
health problems.
- Whey protein concentrate: Protein isolated from
cheese by-products. Contains lactose.
- Ferrous sulphate: a form of iron usually used in supplementation,
however this form is not easily absorbed and is known to cause constipation. It
also has warnings not to be used in cases of inflammatory intestinal disease
(ulcerative colitis, crohn’s disease) and with some medications.
- Thiamine mononitrate: a synthetic form of vitamin B1, known to
cause allergic reactions in some people as it can be more difficult to expel
from the body than natural forms of B1.
- Sodium acid pyrophosphate: this is additive E450, which is an
acidity stabiliser used to help emulsify products. This accounts for the relatively
high amount of phosphorus in Quorn. Long term intake of this can lead to mineral
imbalances in the body and effect bone mineral density.
- Sodium bicarbonate: used to lower stomach acid. Can cause
bloating, nausea and indigestion.
Not all products contained all these, but these were the
common culprits. Check the back label of ingredients to confirm what is in the
product.
So is it the real deal? I found many cases online in which
consumers experience vomiting, diarrhoea and even anaphylactic fits after
having these products. There were companies in the US who were trying to stop
the production of Quorn due to its side effects. However, the continent of
origin, Europe, only a fraction of their consumers suffered these side effects.
Are these side effects due to the mycoprotein, or is it the processing and the
other ingredients added to create the meal?
Also Quorn contains fungi, gluten, lactose and egg products
– so avoid Quorn if you suffer from any allergies to these.
So would I buy Quorn? No. There are other meat-free,
soy-free protein sources which I would use before trying Quorn. Beans, lentils,
quinoa, eggs can all be used as excellent sources of protein and taste so good
that they don’t need to be moulded into fake meat patties to encourage people
to eat them. If people are wanting to reduce their saturated fat content, opt
for lean pieces of meat over fatty steaks. The products seem highly processed
and just because something doesn’t contain meat, doesn’t mean its healthy!
