Effect of formula type and preparation on International Dysphagia Diet Standardisation Initiative thickness level and milk flow rates from bottle teats
In this study we compared IDDSI thickness levels and flow rates between the powder and the ready-to-feed formulations of following infant formulas: Similac Advance, Similac for Spit-Up, Enfamil Infant, and Enfamil Anti-Reflux (A.R.). We found that Enfamil A.R. ready-to-feed formulation was IDDSI “slightly thick” while the other formula types and formulations were all IDDSI “thin” liquids. The standard infant formulas (Similac Advance and Enfamil Infant) had comparable flow rates regardless of whether they were the powder formulation or ready-to-feed formulation. The gastroesophageal reflux (GER) specific formulas (Similac for Spit-Up and Enfamil A.R.) had slower flow rates than the standard formulas. Within the GER-specific formulas, there were differences in flow rates between the powder and ready-to-feed formulations.
