Food and drink thickeners refer to food products that are designed to thicken foods and liquids in order to ease swallowing by patients who suffer from dysphagia.
The use of food and beverage thickeners is very common in institutions such as hospitals, rehabilitation centres, and nursing homes, but they can also be used in homecare environments where patients consume fluids and other foods. Food and beverage thickeners may be mixed with drinks including water, tea, juices, and nutritional shakes.
Thickener powders may be beneficial to individuals with dysphagia or swallowing difficulties, as they may help reduce the risk of choking or aspiration and also keep them hydrated and nourished. These thickening agents help slow down liquids as they move through the mouth and throat, making swallowing safer and more manageable.
Those who have difficulty swallowing may find that consuming thin liquids poses certain risks. Liquids flow faster, and thin liquids may move too quickly through the throat, which can increase swallowing difficulties for some individuals.
Liquid thickeners, which change the consistency of beverages, may help some individuals swallow liquids more comfortably and safely.
When recommended by a healthcare professional, thickened liquids may help:
Speech-language pathologists often recommend thickened liquids after a swallowing evaluation.
Dysphagia can affect individuals differently depending on the underlying condition. Food thickener products are often recommended for individuals diagnosed with dysphagia. Common conditions associated with swallowing difficulties include:
Swallowing changes can become more common with aging, which is why some older adults may require texture-modified diets.
Food and drink thickeners are generally available in starch-based and gum-based formulations.
Starch-based thickeners are commonly used and widely available in clinical and homecare settings. They are often made from modified cornstarch.
Features:
Important consideration: Starch-based products may continue thickening over time after mixing.
Gum-based thickeners are typically made with xanthan gum.
Some caregivers and clinicians prefer gum-based products for their stable consistency.
A thickening agent for fluids can be added to various drinks and foods to assist in creating a safe consistency to swallow for those suffering from dysphagia. Some examples of fluids that can be thickened using a thickening agent include water, coffee, tea, juice, milk, and nutrition shakes. Other than drinks, there are some foods like soups, gravies, purees, and sauces that also employ the use of food thickeners. Different thickening agents work best with different foods and drink types depending on their formulations.
Many dysphagia care providers follow IDDSI (International Dysphagia Diet Standardization Initiative) guidelines to classify liquid thickness. These levels are based on the International Dysphagia Diet Standardization Initiative (IDDSI) framework.
| Level | Consistency |
| Slightly Thick | Thicker than water |
| Mildly Thick | Nectar-like |
| Moderately Thick | Honey-like |
| Extremely Thick | Pudding-like |
Using the correct consistency level is important for swallowing safety.
Most thickener powder products are easy to prepare.
Basic steps include:
Important: Always follow the manufacturer’s instructions and the recommendations of a healthcare professional.
