Abstract

Bone embrittlement with aging, namely osteoporosis, is characterized by low bone mass and deterioration of bone tissue, and can lead to increased risk of fracture. The development of functional foods that can prevent geriatric diseases is in progress. Our focus was on brown rice because of its properties. An interventional study using of ultra-high hydrostatic pressurized brown rice (UHHPBR) for human has not yet been conducted. In this study, we investigated whether long-term dietary intake of UHHPBR prevents aging-related decline of bone mineral density in elderly Japanese individuals. Elderly participants (n=40; mean 73.1 y) in Iinan-cho, Shimane, Japan, were randomly divided into two groups. The UHHPBR-intake group (n=20) consumed 100 g of UHHPBR and 100 g of white rice (WR) per day for 12 mo, while the WR-intake group (n=20) consumed 200 g of WR per day. Pre- and 12-mo post-intervention, bone mineral density was evaluated by quantitative ultrasound. After 12 mo of intervention, the UHHPBR group’s bone mineral density was significantly higher than the WR group’s bone mineral density. Moreover, chronic intake of UHHPBR had no adverse side effects on participants. Long-term oral UHHPBR intake may have beneficial effects on bone mineral density decline and may attenuate osteoporosis in the elderly.
