Allulose vs Tapioca Syrup: which is worse?

What is Allulose?

Allulose (D-psicose) is a rare sugar monosaccharide naturally present in trace amounts in wheat, figs, raisins, and jackfruit. It has about 70% of sucrose's sweetness but provides only 0.4 kcal/g (about 10% of sucrose's calories) because it is absorbed but not metabolized. The FDA exempted allulose from the 'total sugars' declaration in 2019.

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

Allulose: Generally considered safe with a favorable glycemic profile. Human studies show that allulose does not raise blood glucose or insulin. GI effects (bloating, abdominal cramping, diarrhea) have been reported in dose-response studies above 0.4 g/kg body weight; a 2016 study in the journal Food & Chemical Toxicology established a no-observed-adverse-effect level (NOAEL) in humans. Compared to erythritol, no cardiovascular concerns have been raised in the literature.

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.
