Tapioca Syrup vs Sorbitol: which is worse?

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.

What is Sorbitol?

Sorbitol is a sugar alcohol (polyol) naturally found in some fruits, including apples, pears, and prunes. Commercially, it is produced by hydrogenation of glucose. It has approximately 60% of the sweetness of sucrose but provides fewer calories (2.6 kcal/g vs 4 kcal/g for sugar) and does not cause a significant immediate insulin response.

Documented risks

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.

Sorbitol: At doses above 20–50 g/day, sorbitol can cause osmotic diarrhea because it is incompletely absorbed in the small intestine and is fermented by colonic bacteria. EU regulations require products containing more than 10% added polyols to carry the label 'excessive consumption may produce laxative effects.' This is well-known and predictable. Sorbitol is not carcinogenic and does not raise blood glucose significantly, making it suitable for diabetics in controlled amounts.
