Hidden Ingredients and the Food Rounding Rule

Description

Explains how food labeling can be misleading, allowing harmful ingredients to be hidden from consumers. It covers the "rounding rule," which lets manufacturers list under 500 mg of substances like trans fats or MSG as zero, effectively masking their presence. The discussion also highlights incidental additives, such as the neurotoxic solvent hexane, used in processing but often not disclosed on labels. Additionally, it addresses hidden sugars like maltodextrin and dextrose, which can spike blood sugar despite products being labeled “sugar-free.” A practical tip is also shared: using a simple iodine test to detect starches like maltodextrin in foods and supplements.
