IDDSI Framework: Standardised Texture-Modified Food and Thickened Drink Levels
International Dysphagia Diet Standardisation Initiative (IDDSI)
The international standard describing texture-modified foods and thickened drinks on one eight-level scale. Free detailed descriptors, fork-drip and syringe flow testing methods and evidence statements let a caregiver prepare and objectively verify a consistency that is safe to swallow. Swallowing difficulty is one of the main reasons older adults stop eating enough, and this is the only source that turns 'soft diet' into measurable, testable levels.
