The Gross Truth About Natural Flavors

Natural Flavors…

The name sounds innocent enough, but these mild-sounding words are used by the food industry as an umbrella term for some pretty horrible stuff, including certain ingredients that come from extreme animal abuse.

The exact definition of natural flavors from the Code of Federal Regulations is as follows:

“The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional.”

When the phrase ‘natural flavors’ appears on a package, the best move is to call the company and find out what the flavors are actually made from. Of course, I say this assuming that we’re all the kind of people who would be horrified to find out that we might have come close to ingesting fluid from the sex glands of beavers.

Think that sounds absurd? Then you must not have heard of castoreum, which is “used extensively in perfumery and has been added to food as a flavor ingredient for at least 80 years.”

Castoreum is a bitter, orange-brown, odoriferous, oily secretion, found in two sacs between the anus and the external genitals of beavers. The discharge of the castor sac is combined with the beaver’s urine, and used during scent marking of territory. Both male and female beavers possess a pair of castor sacs and a pair of anal glands located in two cavities under the skin between the pelvis and the base of the tail.

Castoreum is a product of the trapping industry. When beavers are skinned for their fur, these glands are taken out, and are sold after being smoked or sun-dried to prevent putrefaction…

Well, that’s a relief.

The European Beaver was hunted to near extinction, both for fur and for castoreum, which was also believed to have medicinal properties. The North American beaver population was once more than 60 million, but as of 1988 was 6–12 million, largely due to extensive hunting and trapping. Although sources report that beaver populations have now recovered to a stable level, some experts say that today’s American beaver population is only 5 percent of what it was when Europeans first settled in North America.

Castoreum is used in “high class” perfumery for “refined leathery nuances.” It is also reportedly used in some incense, and to contribute to the flavor and odor of cigarettes. In food, castoreum is used to flavor candies, drinks, and desserts such as puddings.

Grossed out? Horrified that humans think nothing of killing innocent beings so we can dress ourselves in their fur and flavor our candies with their secretions? I have a solution for you: Go vegan – really vegan. Don’t use cosmetics that are made using animal products, read the ingredients on food packages, call customer support when you see those scary words, ‘natural flavors’, and guess what? You’ll never eat anyone’s anal fluid again.

Natural Flavors usually contain free glutamic acid (MSG). Since it is created from some natural compound and then chemically modified to release the free glutamic acid (MSG), they don't have to label it as such. MSG is a significant migraine trigger

Really wondering if the author or readers actually read the CFR?

Nice try with the fear based writing - the sensationalistic yet completely obscure example of sex gland ingredients?

It's fine to talk about the horrors of castoreum but unlike the cosmetic industry, food labeling laws and regulations are very specific. I'd be more worried about artificial colors and dyes like that neon green frosting your kid just ate.

Eating and dieting based on the latest crunchy fad often has more to do with marketing and even politics than it does with actual health.

If your readers want to actually look into the facts, I'd say be sure to read the labels and actually understand or be curious enough to do a little research beyond the shakey science of sites with a bias.

You people need to get back to reality. Going vegan and starting online chats does not fix anything. Vegan is not the way our bodies are designed to eat. We are designed to consume meat and others foods as well. Not just veggies or whatever else you people eat. Apparently you would all rather consume chemicals and artificial flavors. I hunt and fish and always will, respectfully. I do not condone killing for only animal parts, but people do eat beavers. I will always choose something natural over artificial anytime. Sometimes i consume items with artificial ingredients, but i like those items enough to overlook it. I am healthy! Take a look at your overall vegan health in ten years. You will look like a bag of skin and bones. I know plenty and i would say that they do not seem to be as healthy as people with regular diets. I only signed up to post this comment after looking up what natural flavoring means. Get off your high horses and come back to earth with the rest of us!
