What labeling keyword often signifies lower sodium options in products?

The keyword "reduced sodium" is significant in nutrition labeling as it indicates that a product contains less sodium compared to a standard reference product, usually the same or similar product without the reduction. When a product is labeled as "reduced sodium," it must contain at least 25% less sodium than the standard version, making it a suitable option for individuals who are monitoring their sodium intake for health reasons, such as high blood pressure or heart disease.

Other terms like "cholesterol-free," "low fat," and "no preservatives" refer to different aspects of nutrition and do not specifically indicate lower sodium content. "Cholesterol-free" indicates no cholesterol, "low fat" pertains to fat content rather than sodium, and "no preservatives" suggests the absence of artificial or synthetic additives, which doesn't directly relate to sodium levels. Therefore, "reduced sodium" is the correct choice for highlighting lower sodium options.
