An object of the present invention is to provide a novel protein material useful for the prevention or treatment of various bone diseases such as osteoporosis, fracture, rheumatism, and arthritis by safe and daily intake. Another object of the present invention is to provide a food or drink or feed for strengthening bones useful for the prevention or treatment of various bone diseases such as osteoporosis, fracture, rheumatism, and arthritis by oral ingestion. The above subject contains 2 to 15 mg/100 mg of angiogenin and/or angiogenin decomposition product, and further contains lactoperoxidase and/or lactoperoxidase decomposition product, angiogenin and/or angiogenin decomposition product It is solved by the protein material contained in the range of 0.3-20 in mass ratio with respect to the decomposition product of genin. By ingesting these protein materials, it is possible to strengthen bones, in particular, prevent and treat various bone diseases such as osteoporosis, fractures, rheumatism, and arthritis. |
