Lactic Acid vs Tapioca Syrup: which is worse?

What is Lactic Acid?

Lactic acid is an organic acid naturally produced during fermentation of carbohydrates by lactic acid bacteria. It gives fermented foods such as yogurt, cheese, and sauerkraut their characteristic tangy flavor. Commercial lactic acid used in food is produced by bacterial fermentation of glucose or lactose, or in some cases by chemical synthesis.

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

Lactic Acid: Lactic acid is a normal byproduct of human metabolism (produced during anaerobic exercise). It is generally recognized as safe at food additive levels. Excessive consumption of foods acidified with lactic acid could theoretically contribute to dental erosion, as with all acidulants. For individuals with rare inborn errors of lactate metabolism, dietary lactic acid may require monitoring.

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.
