For years, health-conscious folks have debated the fors and againsts of synthetic and pure flavors.

In most of those tête-à-têtes, “nourishing” pure flavors beat out “noxious” synthetic ones.

Not too long ago, nevertheless, pure flavors have copped flak from the identical individuals who as soon as championed them, primarily as a result of many now imagine pure flavors aren’t practically pure sufficient.

What Are “Pure Flavors?”

Based on the FDA, “pure taste” or “pure flavoring” means:

“ . . . the important oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which incorporates the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or related plant materials, meat, seafood, poultry, eggs, dairy merchandise, or fermentation merchandise thereof, whose important operate in meals is flavoring fairly than dietary.”

In different phrases, a pure taste is any meals flavoring derived from a plant or animal.

Why, then, accomplish that many well being and food regimen “gurus” marketing campaign towards pure flavors, claiming they’re really wholly unnatural and laced with “poisonous chemical compounds?”

Primarily as a result of they misunderstand meals chemistry.

How Pure Are Pure Flavors?

For a taste to qualify as pure, it should have come from a pure supply. Nonetheless, it may be a supply you wouldn’t count on, and it may be processed in an unnatural approach (that features using synthetic chemical compounds).

Take vanilla, for instance. You would possibly assume a pure vanilla flavoring comes from vanilla seeds scraped from vanilla pods, however this would be far too costly and unsustainable due to the labor concerned. 

Scientists found a while in the past, nevertheless, that the principle taste element of vanilla seeds (vanillin) can be obtained from different sources, together with celery seeds, tobacco leaves, orange leaves, and lemon peels. Pure sufficient. 

However the vanillin extraction course of? 

That often entails artificial chemical compounds like natural solvents and acids or particular enzymes. In accordance to the FDA, such substances are permissible within the creation of a “pure” taste even after they’re current within the closing product (albeit at insignificant ranges).

Consequently, you’ll be able to have FDA-sanctioned “pure” vanilla flavoring that didn’t come from a vanilla plant and that incorporates hint quantities of unnatural compounds.

When some individuals see how this sausage is made, they really feel hoodwinked as a result of they’d at all times assumed pure flavoring was “100% pure in each approach.” Therefore the outraged bloggers fuming over the “harmful chemical compounds” lurking in purportedly healthful dietary supplements, meals, and drinks.

The issue with this line of condemnation, nevertheless, is it ignores the abundance of scientific proof displaying that pure (and synthetic, for that matter) flavors aren’t dangerous except they’re eaten to excessive extra. 

Within the case of vanillin, as an illustration, analysis exhibits the LD50 (the acute dose that causes 50% of check animals to die) in rats is 1,580-to-3,300 milligrams per kilogram of physique weight. 

Translate that to a 155-pound human, and also you get an LD50 dose of between 111 and 231 grams, and relate that to, say, a cake recipe that requires a drop or two of vanilla extract (containing 0.5-to-1 gram of vanillin), and also you attain the belief that you just’d must eat between 200 and 500 desserts in a single sitting to ingest sufficient vanillin to have a 50/50 probability of dying.

A skeptic would possibly acknowledge that it basically requires suicide by flavoring to die from it but additionally level out that there are numerous unwelcome results that would happen in need of dying, starting from one thing delicate like a abdomen ache to one thing extreme like a illness, and that a lot smaller quantities of flavoring, if eaten usually sufficient, may produce such reactions.

They’re not totally fallacious—when you eat sufficient flavoring usually sufficient, you’ll hurt your well being—however there’s no proof to recommend you’ll be able to virtually come near this higher restrict, particularly when you largely eat comparatively unprocessed and nutritious meals and eat small quantities of flavoring in dietary supplements, treats, and drinks (as many health folks do). 

What’s extra, some pure flavors are produced with out chemical components (together with all natural flavors) and include no artificial substances in any respect. (And in case you’re questioning, my sports activities diet firm Legion makes use of these extra “mildly” processed sorts of pure flavoring.)
