Invert Sugar vs Soy Lecithin: which is worse?

What is Invert Sugar?

Invert sugar is a mixture of equal parts glucose and fructose produced by the acid or enzymatic hydrolysis of sucrose. It is sweeter than table sugar by about 25% and has enhanced moisture-retaining properties. Bees naturally produce invert sugar in honey through the enzyme invertase.

What is Soy Lecithin?

Soy lecithin is a phospholipid mixture extracted from soybeans during oil processing, primarily composed of phosphatidylcholine, phosphatidylethanolamine, and phosphatidylinositol. It is one of the most widely used food emulsifiers globally. Most commercial soy lecithin is derived from genetically modified soybeans, though organic varieties are available.

Documented risks

Invert Sugar: Invert sugar poses the same metabolic risks as other added sugars. The free fructose component is metabolized directly in the liver, and excessive fructose consumption has been linked to non-alcoholic fatty liver disease, increased triglycerides, and insulin resistance, as documented in multiple reviews including a 2013 paper in Current Opinion in Lipidology. At moderate consumption, it is not specifically more harmful than sucrose. Regulatory agencies worldwide permit its use without restriction.

Soy Lecithin: Generally recognized as safe. Soy lecithin is highly refined, and most soy proteins that trigger allergies are removed during processing; however, highly soy-allergic individuals may react. EFSA conducted a safety re-evaluation in 2017 and confirmed its safety at current use levels. The majority of commercial soy lecithin comes from GMO soybeans, which some consumers prefer to avoid. No major toxicological risks have been identified at normal dietary exposure levels.
