I have isolated a sugar free syrup as giving me a blood sugar spike. There was no Maltitol, but the first ingredient is natural flavor. I tried another brand that didn’t have any natural flavor and there’s no spike. We all know we can’t trust labels so I was wondering if anyone had some insight on what is considered a natural flavor in a sugar free product and how that could have a negative effect on my blood sugar.
Any info on "Natural Flavors" spiking blood sugar?

Anything else in there known to cause that? What brand and product was it? What are you calling a spike?

Natural flavorings. WOW there is so much leeway on what is ‘in that description’ and allowed to be there. Just google what is in it and what could be in it and what it is all about and it opens your eyes to how 2 little words can bring a world of trouble to our bodies

@kyarn To answer this question, you would need to consult the governmental agency in your country that regulates food products. For example, in the U.S., the FDA insists that non-nutritive sweeteners cannot be sold or used in food products, unless the manufacturer can show proof that the product in question has no effect on serum glucose. I have no idea whether the same stipulation applies to “natural flavours.” I suspect not.
Be aware, furthermore, that the sugar industry tries to claim that sugar (sucrose) is a “natural” ingredient, sometimes trying to disguise its presence in foods by calling it such names as “cane juice,” “agave nectar,” and the like.
