The definition of "natural flavor" under the Code of Federal Regulations is: “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 isflavoring rather than nutritional” (21CFR101.22).

What about the flavorings used in organic foods? Foods certified by the National Organic Program (NOP) must be grown and processed using organic farming methods without synthetic pesticides, bioengineered genes, petroleum-based fertilizers andsewage sludge-based fertilizers. Organic livestock cannot be fed antibiotics or growth hormones. The term "organic" is not synonymous with "natural."

The USDA’s Food Safety and Inspection Service (FSIS) defines “natural” as “a product containing no artificial ingredient or added color and is only minimally processed (a process which does not fundamentally alter the raw product) may be labeled natural.” Most foods labeled natural, including its flavorings, are not subject to government controls beyond the regulations and heath codes.

Remember, "natural flavors" are listed on the label because they have been added to the food. This means that it's not natural to whatever food product you are consuming. Most processed foods have flavors (either natural, artificial, or both) added to them during the production process because all of the "flavor" has been processed out.

Flavors are made by “flavorists” in a laboratory by blending natural or synthetic chemicals together to enhance taste. Blending chemicals derived from a natural source, such as a plant or animal product makes natural flavors.

Combining synthetic (human-made) chemicals, on the other hand, makes artificial flavors.

Therefore, the primary difference between natural and artificial flavorings is in the origin of the chemicals used to producetheir tastes.

"Natural" flavors are made in a lab by "flavorists" just like "artificial" ones.

Sure it's a "natural flavoring" , but does "being natural" mean that you want to eat it?

Many disgusting substances are considered "natural," yet you may not want to be eating them.

For example, , millions of people across the globe are eating "beaver butt" and don't even realize it.

It's called "castoreum," and it's emitted from the castor sacs within the animal's anus. For a beaver, this slimy brown substance is used to mark its territory, but for us humans, it's used as an additive that is often labeled as "natural flavoring" in the foods we eat - vanilla, strawberry and raspberry probably being the most common.

Why is castoreum used? The most notable characteristic (after being processed) has to be the smell of castoreum. Instead of smelling horrible, like most people would expect from an anally produced secretion, it has a pleasant scent, which supposedly makes it a perfect candidate for food flavoring and other products.

Another example? You might assume that the added “natural flavoring” in a citrus-based food comes from an orange or grapefruit but according to the FDA definition, it could be some food science miracle and actually come from chicken feet.

The bottom line is that you have to read labels. “Natural” might not be so natural, and even some organic foods might contain some of these “natural flavors.” There are still many grey areas for consumers and producers alike.

The bottom line questions are "are natural flavors harmful to my health and how do they effect weight loss?”

The answer is they are probably no more than anything else processed in a lab. haven’t researched the health aspect specifically yet, however my common sense tells me if I eat food that contains something manufactured in a lab, I am eating highly processed, and chemically processed ingredients without knowing their actual source. If you MUST keep eating processed foods with "natural flavors", you can always contact the company and ask the source of them.

As to how they effect weight loss, again, common sense would say that if my body is not sure what exactly it is and was not designed to process it, it will not burn those calories the same.
