Early dietary experience shapes salt preference of infants and preschoolers
For decades, public health initiatives have encouraged people to put less salt in their foods and to check packaged foods for sodium content, but many people still consume too much salt. In this NIDCD-funded research, investigators at the Monell Chemical Senses Center report that babies exposed early to starchy, salty foods will develop a greater preference for salty taste, by as early as six months of age, than will infants who have not been given salty foods. The exposed babies consumed 55 percent more salt than their unexposed peers during a preference test. This preference is shown to last into the preschool years, where exposed children are more likely to consume plain salt. These findings indicate the significant role of early dietary experiences in shaping taste preferences that last into childhood and could potentially influence taste preferences in adults.
