# IDDSI Level 0: Thin

Canonical: [https://followyourswallow.com/iddsi/level-0](https://followyourswallow.com/iddsi/level-0)

Flows like water.

## What it is

Fast-flowing liquids that flow freely through a straw, cup, or syringe. No thickening at all.

## What it looks like

Water, coffee, tea, juice, broth: anything that splashes.

## Official test

10 mL syringe flow test: 1 mL or less remains after 10 seconds.

## Foods that typically fit

- Water
- Black coffee & tea
- Clear juices
- Broth
- Most oral nutrition shakes (check the label)

## Common mistakes

- Assuming all supplement shakes are thin, many test at Level 1 or 2.
- Ice cream and gelatin melt to thin in the mouth, they count as Level 0 if thin liquids are restricted.




## Safety

Use only the food and drink levels prescribed by the person's qualified clinician. Test the actual serving before it is eaten or drunk.
