[0002]

2. Description of the Related Art In a recent aging society, there is no doubt that eating habits are an important factor in living a healthy elderly life. In other words, eating happily has a function of bringing about mental stability, and a well-balanced diet suitable for the metabolic function of the elderly can maintain immune function, which declines with age, diabetes, high It has functions such as prevention of lifestyle-related diseases such as lipemia. However, with aging, changes in taste due to a decline in sensory functions,
In some cases, it is difficult to take proper nutrition due to factors such as poor dietary intake due to deterioration of chewing and swallowing functions. Specifically, it has been reported that 10 to 15% of self-supporting elderly have protein deficiency, 5% have protein and energy deficiency, and 60 to 80% of hospitalized elderly have some kind of malnutrition. [Clinical Nutrition, No. 93
Vol. 4, No. 4, pp. 418-421, September 1998 (extra issue). Therefore, even for healthy elderly people,
Means for replenishing nutrients such as proteins, which are lacking in ordinary life, have been demanded, and a nutritional composition suitable for this means has been desired.

[0003] Under such circumstances, conventionally, as nutritional compositions, infant formula for infants and infants, and enteral nutrition for patients with illness [Kunio Yamauchi, Kenkichi Yokoyama, “Milk Encyclopedia”, No. 29
Pages 8 to 322, Asakura Shoten, January 20, 1992 (hereinafter referred to as Document 1). Japanese Clinical Clinic, Volume 49, 19
Special Issue 1991 (Vol. 629), "Intravenous and Enteral Nutrition", pp. 197 to 222, pp. 815 to 816,
Nippon Rinsho Co., Ltd., November 28, 1991 (hereinafter referred to as Reference 2). ] Were only known as typical ones. However, these prior arts have the following disadvantages.

[0004]

SUMMARY OF THE INVENTION As disclosed in the above prior art, a formula powder, which is a nutritional composition containing protein, lipid and lactose, has been developed. However, the protein content of the infant formula for infants is adjusted to be low, as described in the literature 1, pages 303 to 304, because the digestive absorption capacity of proteins of infants is low. However, since it is highly regulated for the purpose of supplying energy to infants, even if a child formula powder is ingested, as described above, it is necessary to improve the nutritional status of elderly people who are deficient in protein as a nutrient. There was a problem that it was insufficient.

[0005] Enteral nutrition, which is a nutritional composition containing protein, lipid, and lactose, has been developed. However, enteral nutritional supplements for patients have been developed for the purpose of tube administration as described on page 218 of Reference 2 and have been used for taste reasons such as containing a considerable amount of amino acids and the like. There was a problem that it was not suitable for oral ingestion with a normal meal in terms of smell and smell. In addition, enteral nutritional supplements have been developed mainly for the purpose of satisfying nutritional requirements by solely taking enteral nutritional supplements. Therefore, since the content of protein and lipid is adjusted to be high, such enteral nutritional supplements are used. When the composition was ingested orally, there was a problem that abdominal distension occurred, as is apparent from the test examples described later.

[0006] In view of the above prior art, the present inventors aimed at developing a nutritional composition suitable for nutritional supplementation of proteins and the like that are deficient in normal life of healthy elderly people and the like. Various nutrient compositions were tested, as indicated in part. As a result, the present inventors have found that a nutritional composition containing 18 to 22% of protein, 8 to 14% of lipid, and 28 to 38% of lactose in the total solid content is healthy. The present inventors have found that the present invention is excellent in replenishment of nutrients such as proteins, which are lacking in a normal life of an elderly person or the like, and completed the present invention. An object of the present invention is to provide a novel nutritional composition suitable for nutritional supplementation of healthy elderly people and the like.

[0007]

According to the present invention, there is provided a solid solution comprising 18 to 22% of protein, 7 to 14% of lipid and 28 to 38% of lactose in total solid content. The nutritional composition is characterized in that the weight ratio of calcium to phosphorus contained in the nutritional composition is at least 1.5 (hereinafter referred to as aspect 1), and that the nutritional composition is a powder (Hereinafter, described as mode 2) is also a desirable mode.

A panel of each corresponding test group was allowed to take 20
The number of defecations during the day was counted, the number of defecations per day was calculated, and the average value of the number of defecations in each test group was obtained.

(5) Method for Quantifying Phosphorus and Calcium in Nutrient Composition Raw Materials The content of phosphorus and calcium is determined by a conventional method (ICP emission spectrometry, edited by the Society for Analytical Chemistry, Instrumental Analysis Technique Series, page 225,
(Kyoritsu Publisher, 1988).

(6) Test Method of Calcium Absorption Rate The absorption rate of calcium from the gastrointestinal tract of the oral administration group of each sample was tested as follows, taking the absorption rate of the calcium intravenous group as 100%. Five male Sprangue-Dawley rats (body weight: 100 to 130 g, obtained from Charles River Japan) were used for each test group. Rats in each test group were allowed to freely ingest a commercially available rat breeding feed (MF; manufactured by Oriental Yeast Co., Ltd.) and water, were bred for 2 weeks, were allowed to ingest only water, and were fasted for 12 hours. Then
For the oral administration group, 1 g of each sample added with 0.4 μCi of calcium carbonate (manufactured by Amersham) labeled with ⁴⁵ Ca as an isotope was dissolved in 3 ml of distilled water (manufactured by Wako Pure Chemical Industries) in the fasted rats. Gavage was performed intragastrically by sonde.

In the control group, the intravenous administration group, fasted rats were given 0.4 μm of calcium carbonate (manufactured by Amersham) labeled with ⁴⁵ Ca as an isotope.
Ci was dissolved in 0.1 ml of physiological saline for injection (manufactured by Wako Pure Chemical Industries) and injected intravenously. The rats in each test group were allowed to freely ingest only water, fasted for 36 hours, suffocated under carbon dioxide, incised in the left thigh, and the left femur was taken out. The left femur was ashed, dissolved in 1 ml of 3 mol / l hydrochloric acid (manufactured by Wako Pure Chemical Industries, Ltd.), diluted with 14 ml of a liquid scintillation counter dilution cocktail (manufactured by Amersham), and the radioactivity of the diluted solution was measured by liquid scintillation. It was measured by a counter meter (manufactured by LKB), and the average value of 5 animals in each test group was calculated. Since calcium absorbed into blood vessels is usually used by 100% of the living body, the average value (A) of the radioactivity of the intravenous administration group, which is a control group, is taken as 100% of the calcium absorption rate, and the oral administration group of each sample is used. From the average value of the radioactivity (B), the calcium absorption rate (C) from the gastrointestinal tract of the orally administered group of each sample was calculated based on the following formula. C (%) = (B / A) × 100
