Polydextrose vs Tapioca Syrup: which is worse?

What is Polydextrose?

Polydextrose is a synthetic polymer of glucose (with some sorbitol and citric acid) created under heat and vacuum conditions. It functions as a soluble dietary fiber, providing only 1 kcal/g. It is used to add bulk to reduced-calorie foods while also contributing fiber content. The FDA approved it as GRAS in 1981.

What is Tapioca Syrup?

Tapioca syrup is produced by enzymatically or acid-hydrolyzing tapioca starch (derived from cassava root). It is often marketed as a 'clean label' alternative to corn syrup, particularly in organic and natural food products. Chemically, it is similar to corn syrup, consisting primarily of glucose polymers.

Documented risks

Polydextrose: At doses above ~90 g/day, polydextrose can cause flatulence, bloating, and loose stools. At normal food use levels it is well tolerated. EFSA confirmed its safety in 2012. It functions as a soluble prebiotic fiber, feeding beneficial gut bacteria. No genotoxicity, carcinogenicity, or reproductive toxicity has been identified.

Tapioca Syrup: Tapioca syrup contributes added sugar to the diet and has a high glycemic index comparable to corn syrup. A 2019 investigation by the Clean Label Project found that many 'organic' snack bars sweetened with tapioca syrup had sugar contents equivalent to candy, despite their 'natural' branding. The FDA has noted that tapioca syrup, when listed on ingredient labels without quantification, may obscure the total sugar content of a product. Health impacts are equivalent to those of other refined sugars.
