The short answer
- The speech and language therapist sets the levelThey assessed how this person swallows. Only they should change the level, up or down, however well a meal seems to go.
- Every drink is made to the same thicknessUse the thickener in the plan and follow its tin for the level. Mixing methods differ between products, so do not swap one for another without advice.
- Some foods are riskier than othersIDDSI names textures that are a choking risk, such as bread, nuts, stringy vegetables and soup with pieces in it. Leave them out unless the plan says otherwise.
- Coughing, a wet voice or a chest infection means ring todayThe NHS says to ask for an urgent GP appointment or call 111. Struggling to breathe or choking and unable to speak is 999.

The eight levels
What each IDDSI level means, in plain words
IDDSI is the International Dysphagia Diet Standardisation Initiative. Its framework uses eight levels, numbered 0 to 7. Drinks run from 0 to 4 and food from 3 to 7, so levels 3 and 4 appear on both sides.
- 7
Food
Regular, or Easy to chew
Regular is everyday food of any texture and size. Easy to chew is everyday food that is soft and tender, without hard, tough, chewy, crunchy or crumbly bits, pips, seeds or bones.
- 6
Food
Soft and bite-sized
Soft, tender and moist all the way through, in pieces no bigger than 1.5cm for an adult. It needs chewing but not biting, and breaks apart when pressed with the side of a fork. No ordinary bread.
- 5
Food
Minced and moist
Soft and moist with no thin liquid running off it. Lumps are no wider than 4mm for an adult, about the gap between the prongs of a dinner fork, and easy to squash with the tongue.
- 4
Drink
Extremely thick
Too thick to drink from a cup or suck through a straw, so it is taken with a spoon.
Food
Pureed
Smooth, with no lumps, and not sticky. It holds its shape on a spoon and on a plate, and no liquid separates from it. No chewing is needed.
- 3
Drink
Moderately thick
Can be drunk from a cup, and takes some effort through a straw.
Food
Liquidised
Smooth with no bits, taken with a spoon. It drips slowly through the prongs of a fork and will not hold a shape on the plate.
- 2
Drink
Mildly thick
Can be sipped. It pours quickly off a spoon, but more slowly than an ordinary drink.
- 1
Drink
Slightly thick
A little thicker than water and a little more effort to drink. It still flows through a straw.
- 0
Drink
Thin
Flows like water, and can be drunk from any cup or straw.
A stroke can damage the part of the brain that coordinates the muscles of the mouth and throat, and the Stroke Association explains that swallowing problems, called dysphagia, are very common after a stroke. The danger is food, drink or saliva going into the airway instead of the food pipe. That is called aspiration, and it can lead to a chest infection. Changing the texture of food and the thickness of drinks gives the mouth and throat more time and more control.
Where your relative sits on the ladder was decided by a speech and language therapist who watched them swallow. IDDSI itself says that the clinician is responsible for recommending foods and drinks for a particular patient after a full assessment. So the level on the discharge letter is an instruction for this person, and only the therapist should move it. The Stroke Association points out that someone may feel they can swallow safely without that being certain. If you think things have improved, ask for the swallow to be looked at again. The same applies if they seem worse.
The ladder is the same whatever caused the swallowing problem, so the levels here also apply to swallowing and speech in Parkinson's and to eating and swallowing in later dementia. The Stroke Association also says that many people's swallowing improves in the first few weeks after a stroke, which is one more reason the level is reviewed rather than fixed. The first weeks home after a stroke covers the rest of what changes in that period.
Thickened drinks
Making thickened drinks to the level, every time
Thin drinks move fast through the mouth and throat. A thickened drink slows down, which gives a weakened swallow time to close off the airway. The thickness only helps if it is the same in every cup.
- 1
Check the plan for the level and the product
Before the first cupThe plan should name the IDDSI level for drinks and the thickener to use. Guidance from one NHS formulary says thickeners should only be prescribed on the recommendation of a speech and language therapist, so ask them or the GP how to get more. - 2
Follow the instructions on the tin for that level
Every drinkEach product has its own number of scoops per amount of liquid for each level, and some are added to the cup before the drink. The formulary guidance warns that mixing methods vary between products. Use the scoop that came in the tin. - 3
Stir, then wait before serving
As the tin saysStir until the powder has fully dissolved. Some thickeners need to stand for a short time before the drink reaches its final thickness, and the tin says how long. - 4
Check it looks right, and ask if it does not
Each timeThe therapist can show you what the level should look like on a spoon. If a drink seems too runny or too thick, make it again rather than adding more powder or water to the cup.
Every drink counts, including tea, soup, milk on cereal and the water taken with tablets. A Cambridge University Hospitals leaflet on mildly thick drinks at level 2 says plainly that all drinks should be at that level. It also says thickening nutritional supplement drinks is not recommended, so if your relative has been prescribed build-up drinks, ask the dietitian or therapist how they should be taken.
IDDSI publishes a flow test that uses a 10ml syringe to check which level a drink has reached. Leave it to the therapist unless they show you how to do it, because it needs the right syringe and careful timing. The IDDSI detailed definitions set out the test for anybody who wants to read how it works.
The Stroke Association suggests thickened drinks are more pleasant chilled, flavoured or made fresh. Drinking enough still matters, and keeping an older person hydrated explains the signs of not drinking enough and what helps. If thickened drinks are being left, tell the therapist.
Cooking to the level
Cooking at the right texture, and the foods to leave out
Everyday meals such as cottage pie or fish in sauce can be brought to a level with a fork, a masher, a blender and a good sauce. What catches families out is the food that looks soft and is not, and the plate that mixes two textures in one mouthful.
| Examples IDDSI and the NHS give | Why it is a risk | |
|---|---|---|
| Hard, dry, crunchy or crispy | Nuts, raw carrot, raw apple, crackling, crisp bacon, toast, dry biscuits, popcorn | It takes strong, sustained chewing and plenty of saliva to break these down safely. |
| Tough, stringy or fibrous | Steak, pineapple, celery, rhubarb, runner beans | Pieces can stay joined by a string, with part in the mouth and part in the throat. |
| Chewy or sticky | Sweets, cheese chunks, marshmallows, nut butter, sticky mashed potato, overcooked porridge | They can stick to the roof of the mouth or the cheeks and then fall into the airway. |
| Crumbly | Dry cake, crumble, pastry, bread crusts, scones | Crumbs need good tongue control to gather into one mouthful. |
| Mixed thin and thick | Soup with pieces, cereal in milk it has not soaked up, mince in thin gravy, watermelon | The mouth has to hold the solid while the liquid is swallowed, which is a very complex task. |
| Skins, pips, bones, round or floppy | Peas, sweetcorn, grapes, sausages, fish bones, lettuce, thin cucumber | Round foods can block the airway if swallowed whole, and floppy leaves can cover it. |

Drawn from IDDSI's list of food textures that pose a choking risk and an East Kent Hospitals NHS leaflet for a level 5 diet. Some of these are fine at level 7 easy to chew or regular; the therapist will say which apply to your relative.
Bread needs a special mention. IDDSI says there should be no regular dry bread, sandwiches or toast at level 5 or level 6. Its framework pages have instructions for a softened sandwich if the therapist agrees.
The practical work is in the cooking. An NHS leaflet on minced and moist food and IDDSI's own definitions both describe the same habits:
- Cook meat and vegetables until they are very soft, then mash, mince or blend them to the size the level allows. For level 5 that is lumps no wider than the gap between the prongs of a fork.
- Moisten with a thick, smooth sauce or gravy, and drain off any thin liquid so none separates on the plate.
- If meat cannot be minced finely enough, IDDSI says it should be pureed instead.
- Scrape off any crust that forms in the oven, such as a cheese topping.
- Mash each food separately, so a plate keeps its colours and flavours. The Stroke Association suggests food moulds for making pureed food look appetising.
An East Kent Hospitals leaflet on the level 5 diet says some supermarket ready meals such as cottage pie can be mashed to level 5, and it lists companies that deliver texture-modified meals. Check any ready-made meal against the level before serving it.
At the table
Mealtimes, mouth care and tablets
The level on the plate is half of it. How someone sits, how fast the spoon comes, and how clean their mouth is afterwards also affect whether food and drink go the right way.
What helps a meal go safely
- Sit them upright in a chair, feet flat on the floor, with a pillow at the side if they lean
- Turn the television off so they can concentrate on eating
- Offer small mouthfuls and small sips, and let each one be finished before the next
- Show or describe what is on the spoon, and ask before moving to another food
- Allow as long as the meal takes, and give some privacy if they feel self-conscious
What to avoid
- Feeding someone who is drowsy or very tired, or who is lying down
- Talking to them while they are swallowing
- Straws or spouted cups, unless the therapist has said they are safe
- Rushing, or offering too much at once
- Treating them like a child
These points come from the Stroke Association's advice for family members helping someone eat. The therapist may add strategies for your relative, such as a particular head position, because NICE asks for people with dysphagia after a stroke to be supported using methods advised by a dysphagia-trained professional. Write those down with the plan. An NHS leaflet adds that the mouth should be fully cleared at the end of a meal. If eating tires them, the Stroke Association suggests smaller meals through the day.
Mouth care matters more when the swallow is unsafeSection titled Mouth%20care%20matters%20more%20when%20the%20swallow%20is%20unsafe
The mouth holds a lot of bacteria, and if saliva carrying them is breathed in, it can cause pneumonia. NICE says people with dysphagia after a stroke should be supported with an effective mouth care routine because this decreases the risk of aspiration pneumonia. NICE asks for teeth and gums to be brushed at least twice a day. Where somebody cannot do it themselves, NICE says a trained professional, family member or carer should do or supervise it. An Oxford Health NHS leaflet on mouth care for people with swallowing problems suggests a soft, small-headed toothbrush. It also says to check the weaker side of the mouth is clear of food after every meal, and to ask the therapist before using mouthwash, because mouthwash is a thin liquid. The Stroke Association adds that non-foaming toothpaste can reduce the risk of aspiration. Ask the ward or the therapist to show you how before discharge, and daily mouth care, dentures and when to call a dentist covers the routine at home.
Tablets are a swallowing question tooSection titled Tablets%20are%20a%20swallowing%20question%20too
A tablet with a glass of water is a thin drink with a solid in it. Do not crush tablets, open capsules or mix medicines into food without advice. The NHS says a pharmacist can advise on other forms of a medicine, such as a liquid or a dissolvable tablet, and that crushing or opening should only be done on their advice. NICE asks for medicines to be reviewed where somebody with dysphagia cannot take tablets. Ring the community pharmacist or the GP, and what carers can and cannot do with medication covers the carer's side of it.
When the swallow changes
Signs the swallow is getting worse, and who to ring
The Stroke Association says swallowing problems are not always obvious, so it helps to know the quieter signs as well as a cough or a choke. Each of them is something a person at the table can see or hear.
| What you might see | What to do | |
|---|---|---|
| 999, now | Struggling to breathe, choking, gasping and unable to speak. Pale, blue or blotchy skin, lips or tongue. Sudden confusion. | Call 999. The NHS lists these as reasons to call 999 or go to A&E. |
| The same day | Coughing or choking at meals. A wet, gurgly voice after eating or drinking. Short of breath after meals. A temperature, a new cough or breathlessness. | Ask for an urgent GP appointment or call 111, as the NHS advises. Tell the speech and language therapist as well. |
| This week | Meals taking much longer. Food left in the mouth after swallowing. Clothes getting looser. Drinks being refused. | Ring the speech and language therapist, the dietitian or the stroke nurse. If you have no therapist, the Stroke Association says to contact the GP. |

Signs from the NHS pages on dysphagia and pneumonia and the Stroke Association's page on swallowing problems. If you are unsure which row applies, call 111.
The NHS lists coughing or choking when eating or drinking, a wet, gurgly voice and repeated chest infections as signs of dysphagia, and says that over time it can cause weight loss and dehydration. The NHS page on pneumonia notes that confusion is a common symptom in older people, so new muddle can be the first sign rather than a cough. NICE also asks that families and carers are given information on how to help someone who is coughing or choking while eating or drinking. Ask the therapist for that before discharge, and consider a first aid course for whoever does the meals.
Keeping weight and fluids upSection titled Keeping%20weight%20and%20fluids%20up
A modified diet can make it harder to eat enough. The Stroke Association says that if someone weighs less than usual or their clothes are getting looser, speak to the dietitian, the therapist or the stroke nurse. The East Kent leaflet suggests weighing once a week, eating little and often, and making food more nourishing with whole milk, cheese, butter and cream. What happens when an older person does not eat enough sets out why weight loss matters. If swallowing stays unsafe and weight keeps falling, the stroke team may raise tube feeding, and PEG feeding at home explains what that involves.
What a carer does
What a paid carer can do, and what stays with the therapist
A carer who comes at mealtimes can take on much of the daily work of a modified diet. The decisions about the level stay with the speech and language therapist.

Carers on PrimeCarers are self-employed and set their own rates, and you choose them yourself. Before a carer appears, we check their identity and right to work and an enhanced DBS check (or PVG in Scotland, Access NI in Northern Ireland) issued within the last 18 months, and we interview them online. We do not check qualifications, training or references, so anything a carer says about dysphagia or texture-modified food is their own account on their profile, and it is for you to ask them about it. Every visit booked through PrimeCarers is insured, by the carer's own policy or by cover PrimeCarers arranges where they do not hold one. How we check every carer sets this out.
Ask the therapist to show the carer, as well as you, how the drinks are made and how a meal is given, then write it into a care plan you draw up together. Under the agreement between client and carer, the carer keeps discretion over how they work and should not take on work they feel unqualified to do, so ask whether they are comfortable before the first visit. Tube feeding is different: it is a healthcare task that a carer may do only after a professional has trained and signed them off for that person, which delegated healthcare tasks explains.
If you would like help at mealtimes, you can search for carers near you and compare their rates. An hour at lunch and an hour at teatime every day is 14 hours a week, which costs £252 to £350 on PrimeCarers with our fee included. An agency charges £28 to £35 an hour for the same visit. How many visits a week your parent needs helps you build the rest of the week, and rehab at home after a stroke covers how the carer fits around the therapists.
Questions
Questions families ask about dysphagia diets
Level 5 is minced and moist food. It is soft and moist with no thin liquid running off it, and for an adult the lumps are no wider than 4mm, about the gap between the prongs of a dinner fork. It needs very little chewing. Meat that cannot be minced that finely should be pureed instead, and ordinary bread, sandwiches and toast are left out.
Not on your own. The speech and language therapist chose the level after assessing her swallow, and only they should change it. The Stroke Association says someone can feel they are swallowing safely without that being certain. If you think she has improved, ring the therapist and ask for a review.
Yes, if the plan says drinks are thickened, every drink is made to that level, including tea, coffee, soup and the water taken with tablets. Supplement drinks are different, and one NHS leaflet advises against thickening them, so ask the therapist or dietitian how those should be taken.
Only if a pharmacist or the GP says that particular medicine can be crushed. The NHS says crushing tablets or opening capsules should only be done on a pharmacist's advice, because it can stop some medicines working properly. Some medicines come as a liquid or a dissolvable tablet, so ask the pharmacist.
A carer can cook and serve food at the level in the plan, make up thickened drinks, help at the table and tell you about any change they notice. We do not check training or qualifications, so ask a carer about their experience with dysphagia, and ask the therapist to show them how your relative's food and drinks are made.
