Level 4 — Puréed

Smooth Yogurt

Plain smooth yogurt without fruit pieces or granola — a convenient, protein-rich IDDSI Level 4 (Puréed) food requiring no preparation.

Natural IDDSI Level

Smooth plain yogurt is uniformly cohesive, holds its shape on a spoon, falls as a mass when tilted, and contains no particles — meeting Level 4 criteria without any modification. Greek yogurt is thicker and more reliably Level 4; standard yogurt may approach Level 3 when thinned by mixing.

Safe Preparation

Choose full-fat plain yogurt (Greek-style preferred). Serve directly from the container without stirring vigorously — stirring can thin the gel. For flavour, mix in smooth fruit purée (banana, mango) at no more than 10% by volume. Avoid flavoured yogurts with fruit pieces, seeds, or granola.

  • Greek yogurt (strained) is thicker and more reliably Level 4 than standard yogurt.
  • Full-fat yogurt provides more calories, important for malnourished patients.
  • Keep refrigerated until service — warm yogurt thins and may shift to Level 3.
  • Fortify with protein powder for patients with high protein requirements.

Important Warnings

  • Avoid yogurts with fruit pieces, seeds, or crunchy toppings — these are choking hazards.

Frequently Asked Questions

Can smooth yogurt meet protein requirements for dysphagia patients?

Greek yogurt provides approximately 10 g of protein per 100 g, making it one of the highest-protein natural Level 4 foods. Standard yogurt provides approximately 4–5 g per 100 g. For patients with elevated protein needs (post-surgery, pressure injury healing), Greek yogurt is an efficient protein source that requires no preparation and is palatable cold.
