IDDSI Level 5 Minced and Moist: Complete Guide for Patients and Carers

IDDSI Level 5 — Minced and Moist — is prescribed for people who have some chewing ability but cannot safely manage regular-sized pieces of food. It sits between the more restrictive Level 4 (Pureed) and the less modified Level 6 (Soft and Bite-Sized), and is one of the most commonly prescribed solid food levels in Hong Kong’s Hospital Authority (HA) dysphagia diet system.

What Defines Level 5?

The International Dysphagia Diet Standardisation Initiative (IDDSI) defines Level 5 by two combined requirements: particle size and moisture.

Particle size. All food particles must be no larger than 4 mm in any dimension for adults (2 mm for children). The standard fork test uses the tines of a fork as a guide: particles should fit easily between the tines, not bridge across them.

Moisture. Food must be cohesive and moist throughout — not just on the surface. A particle that is moist outside but dry and crumbly inside may fragment into small hard pieces during chewing, posing an aspiration risk. The food should be soft enough to mash against the roof of the mouth with the tongue alone, without requiring teeth.

Fork test. Place a small amount of Level 5 food on a fork and tilt the fork. The food should hold together and not fall through the tines, but should slide off the fork as a cohesive soft mass. It should not be so liquid that it runs through, nor so firm that it holds a rigid shape.

Who Is Prescribed Level 5?

Level 5 is appropriate for people who:

• Have mild-to-moderate chewing impairment (reduced dentition, ill-fitting dentures, post-surgical jaw restriction)
• Have a mildly impaired swallowing mechanism where small, cohesive, moist boluses can be managed safely but larger or drier pieces cannot
• Are transitioning upward from Level 4 Pureed as swallowing function improves
• Have fatigue-related dysphagia where the cognitive and physical effort of chewing full-sized pieces is unsustainable across a complete meal

It is not appropriate for people who require pureed or liquidised food, or who cannot manage solid particles of any size safely.

HK Foods That Work Well at Level 5

Hong Kong cuisine offers many dishes that are naturally close to Level 5 or can be easily adapted:

Protein sources

• Minced pork (豬肉碎): the most versatile option. Steam with silken tofu, add to congee, or use as a topping for soft rice. Ensure it is moist throughout — dry pork mince is unsafe.
• Soft fish fillet (蒸魚): steamed garoupa or cod, skin and bones removed, flaked finely. The texture is naturally moist and cohesive.
• Silken tofu (嫩豆腐): naturally Level 4–5. Scrambled with egg or steamed with minced pork in a classic Hong Kong home preparation that meets Level 5 easily.
• Soft-steamed egg (蒸蛋): smooth and cohesive; adjust to Level 4 or 5 depending on consistency.
• Minced chicken in broth: softer than pork and easy to control for moisture.

Carbohydrates

• Congee (粥): base congee is Level 3–4; with minced additions and thicker consistency achieves Level 5.
• Well-cooked soft rice with sufficient sauce: plain dry rice is never Level 5 and is a common mistake. Rice must be very well cooked (soft, slightly sticky) and served with adequate sauce or gravy to maintain cohesion.
• Soft noodles cut into 2 cm pieces: thin rice noodles (米粉) cooked until very soft and cut short.

Vegetables

• Well-cooked Chinese broccoli stems (芥蘭), cut finely
• Soft-cooked carrot, mashed slightly but not fully pureed
• Soft-cooked pumpkin or sweet potato (南瓜 / 番薯)

Foods to avoid at Level 5

• Whole grains, seeds, nuts
• Stringy vegetables (celery, raw bean sprouts)
• Tough meat (beef tendon, pork knuckle, whole cuts)
• Dry bread, toast, crackers
• Whole rice grains in insufficient sauce
• Crispy or fried items

Meal Planning at Level 5

A practical Level 5 day in Hong Kong might look like:

• Breakfast: soft congee with minced pork and century egg (皮蛋瘦肉粥), or steamed egg with silken tofu
• Lunch: soft rice with steamed fish, mashed pumpkin, and a soft-cooked vegetable in sauce
• Dinner: minced chicken in broth over well-cooked soft noodles, with soft silken tofu
• Snack: smooth custard or soft-set pudding, soft ripe banana mashed to Level 5 consistency

Avoid relying on a single protein source. Rotate between fish, egg, tofu, and minced meat to maintain nutritional variety.

Transitioning from Hospital to Home

When a patient is discharged on a Level 5 diet, the hospital SLT should provide:

1. A written diet prescription specifying IDDSI Level 5 and any fluid thickness requirements
2. A demonstration of the fork test so the carer can verify food at home
3. Guidance on thickened fluids if these are also required

At home, carers and domestic helpers need to understand that the Level 5 requirement applies to every meal, every day — not just when the patient appears to be struggling. Aspiration can occur silently without obvious coughing.

When to Contact the SLT

Contact the speech-language therapy department if:

• The patient coughs or chokes consistently on Level 5 foods
• The patient loses weight — this may signal insufficient intake or inadequate moisture
• The patient refuses Level 5 meals for more than two consecutive days
• The patient’s medical condition changes (new stroke, chest infection, significant fatigue)

A repeat clinical swallowing assessment or instrumental study may be needed to reassess the prescription.
