Corn Syrup Solids vs Silicon Dioxide: which is worse?

What is Corn Syrup Solids?

Corn syrup solids are produced by drying corn syrup to a moisture content below 10%, yielding a free-flowing powder. They are composed of a mixture of glucose polymers (polysaccharides) and monosaccharides derived from corn starch hydrolysis. Unlike liquid corn syrup, they are used in powdered products such as non-dairy creamers, infant formula, and seasoning blends.

What is Silicon Dioxide?

Silicon dioxide (silica) is a naturally occurring mineral compound used as an anti-caking agent in powdered and granular foods. The food-grade form is amorphous (non-crystalline) synthetic silica, distinct from the crystalline quartz form associated with lung disease. It absorbs moisture and prevents clumping in powders.

Documented risks

Corn Syrup Solids: Corn syrup solids contribute to added sugar intake and share the metabolic risks of high-sugar diets, including increased risk of obesity, type 2 diabetes, and dental caries. Their presence in infant formula has raised particular concern among pediatric nutritionists, as they have a high glycemic index and provide no nutritional benefit beyond calories. The American Academy of Pediatrics recommends limiting added sugars for all age groups, including infants. Regulatory agencies have not specifically restricted corn syrup solids.

Silicon Dioxide: Food-grade amorphous silicon dioxide is generally recognized as safe. EFSA re-evaluated it in 2018 and concluded there was no safety concern at typical dietary exposure levels; however, the panel noted uncertainty about nanoparticle forms. The food form should not be confused with crystalline silica (quartz) dust, which is a recognized carcinogen when inhaled occupationally. Ingested amorphous silica passes through the body largely unabsorbed.
