Abstract

Nutritional products having improved cohesiveness of food boluses and methods of making and using same are provided. The nutritional products may include nutritional compositions and high molecular weight, water-soluble polymers such that the nutritional products have extensional viscosities that provide improved cohesiveness to the nutritional products and Trouton ratios of at least 6. Methods of administering such nutritional products to patients having impaired swallowing ability and/or dysphagia are also provided.

First claim

The invention is claimed as follows:

1. A method of treating an individual having a swallowing disorder, the method comprising:
administering an effective amount of a liquid nutritional product to the individual having the swallowing disorder, the liquid nutritional product comprising a nutritional composition and a plant-derived mucilage selected from the group consisting of mallow mucilage, ribwort mucilage, mullein mucilage, and mixtures thereof, the liquid nutritional product comprises an amount of the plant-derived mucilage such that the liquid nutritional product has an increased cohesiveness relative to the nutritional composition and has a Trouton ratio of 6 to 15.

2. The method of claim 1 , wherein the liquid nutritional product has an extensional viscosity greater than 100 mPa s.

3. The method of claim 1 , wherein the liquid nutritional product has a Trouton ratio of about 10.

4. The method of claim 1 , wherein the swallowing disorder is at least one of dysphagia or compromised saliva excretion.

5. The method of claim 1 , wherein the liquid nutritional product has a form selected from the group consisting of pharmaceutical formulations, nutritional formulations, dietary supplements, functional food and beverage products, and combinations thereof.

6. The method of claim 1 , wherein the liquid nutritional product does not contain any starch, does not contain any xanthan gum, and does not contain any carrageenan.

7. The method of claim 1 , wherein the liquid nutritional product further comprises an additional ingredient selected from the group consisting of a probiotic, a prebiotic, an amino acid, a fatty acid, a phytonutrient, an antioxidant, and mixtures thereof.
