Tapioca Syrup vs Guar Gum: 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 Guar Gum?

Guar gum is a galactomannan polysaccharide extracted from guar beans (Cyamopsis tetragonoloba), grown primarily in India and Pakistan. It is a highly effective thickener — approximately 8 times more powerful than cornstarch — and functions as a dietary fiber. It is used extensively in food, pharmaceutical, and industrial applications.

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.

Guar Gum: Generally recognized as safe. At high doses (e.g., dietary supplement doses of 10–20 g/day), guar gum can cause flatulence, bloating, and diarrhea. Historically, concentrated guar gum dietary supplements were associated with esophageal obstruction, prompting the FDA to ban such supplements in 1992. At typical food additive use levels, no significant safety concerns have been identified. EFSA confirmed its safety as a food additive in 2017.
