Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nutritional composition and a liquid diet suitable for supplementing zinc by an enteral nutritional supplementation method, and more particularly to a nutritional supplement containing a necessary amount of zinc for bedridden and weak elderly people. The present invention relates to a nutritional composition and a liquid diet suitable for enterally supplying various nutrients.

[0002]

2. Description of the Related Art Enteral nutrition is a nutritional supplementation method using an oral nutritional composition or a tube nutritional composition. A typical nutritional composition is a liquid diet. BACKGROUND ART Liquid foods are administered to patients who have difficulty swallowing foods, and recently, are widely used as a means for supplying necessary nutrition to elderly people such as bedridden elderly people. Especially for elderly people,
Nutrition by a liquid diet is important, as only 40% are said to be in PEM (protein and energy undernutrition).

However, since liquid foods are prepared artificially, there is a tendency that there is a shortage of essential trace elements that are harmless and can be absorbed from the digestive tract. Of the trace elements, especially zinc,
It plays an important role as a central active element of more than 200 kinds of enzymes in living organisms, and is a trace metal important for maintaining the function of cells.

[0004] Specifically, zinc plays an important role in wound healing, and has a function of accelerating the recovery of pressure sores, which are often found in bedridden elderly people. In addition, other zinc deficiencies are known, such as skin eruption, stomatitis, glossitis, hair loss, nail changes, intestinal extremity skin inflammation such as diarrhea, abnormal taste, dwarfism, and decreased immunity. I have. Incidentally, the recommended amount of zinc is 15 mg per day for adult boys and 12 mg per day for adult girls [fifth revised Japanese nutritional requirement (published by Daiichi Publisher)]. Therefore, various liquid foods containing zinc have been proposed. However, at present, inorganic salts such as zinc sulfate cannot be legally used, and natural food materials having a high zinc content must be added.

[0005]

[0006] Very few natural food materials have a high zinc content. In addition, liquid foods are usually thick liquids, and must not cause coagulation and sedimentation. In addition, flavor is also an important factor because it is a food. As a food material having a high zinc content, oyster meat extract, sunflower oligotin and the like are generally known. Japanese Patent Application Laid-Open No. 9-132531 discloses an oyster meat extract containing a high concentration of zinc as a liquid food. It has been proposed to add. However, when these food materials are added to a thick liquid food, problems such as aggregation of the liquid food and deterioration of flavor arise.

[0006] Saltia, which is a seaweed belonging to the genus Hibamata, is known as a food material having a high zinc content. However, Saltia has a large particle size and is poorly dispersible in a thick liquid food. There is a problem that precipitation occurs. Therefore, when a precipitation inhibitor such as crystalline cellulose is added to disperse the saltia in the thick liquid food, the viscosity of the thick liquid food increases, and the texture deteriorates. Further, if Saltia is finely pulverized in advance, the dispersibility in a thick liquid food is improved, but there is a problem that the color tone is deteriorated. An object of the present invention is to provide a nutritional composition and a liquid food that can supply zinc to an elderly person or the like in an amount sufficient to prevent zinc deficiency, and that are safe and do not impair the properties or flavor. It is.

[0007]

Means for Solving the Problems The present inventors have intensively studied various food materials as a zinc source that can be added to a liquid food, and as a result, zinc containing yeast is taken up in the cells and strongly binds. Therefore, it was found that there was no decrease in flavor due to zinc, and that it was highly safe and excellent in dispersibility in a thick liquid food. The nutritional composition of the present invention has been completed on the basis of such findings, and is characterized in that zinc-containing yeast is contained in a nutritional composition for enteral nutrition. The nutritional composition of the present invention containing the above-mentioned zinc-containing yeast can be suitably used as a liquid food, particularly a highly nutrient and high energy concentrated liquid food.

The nutritional composition of the present invention comprises calcium and magnesium in a weight ratio of 2: 1 to 1 in addition to zinc.
It is preferable to contain it at a ratio of 1: 1. As a result, it is possible to prevent ischemic heart disease, which is common in the elderly. The liquid food of the present invention has a protein of 0 to 100 g / L,
Carbohydrate 0-500 g / L, lipid 0-120 g / L, dietary fiber 0-50 g / L and zinc-containing yeast 0.05-50 g
/ L, energy is 90kc per 100mL
a1 or more. As a result, PEM and zinc deficiency, which are often present in bedridden frail elderly people, can be reliably avoided, and necessary nutrition and energy can be easily supplied by enteral nutrition.
