PHOSPHORUS

Phosphorus is the second most abundant mineral in the body. It plays an important role in the formation of bones and teeth, protein production and energy-producing activities in cells. Phosphorus is widely distributed in foods.1 Major food sources of phosphorus are foods containing protein such as meat and milk products.2

Around one in thirty people aged two years and over (1% of males and 4% of females) had a usual intake of phosphorus below their requirements. Children aged 9-18 years have the highest requirements for phosphorus at nearly double that of adults, and this age group had the highest proportions with inadequate intakes. Nearly one in three females aged 9-18 years had inadequate intakes of phosphorus (28% of those aged 9-13 years and 30% of those aged 14-18 years). Females aged 2-18 years were three times as likely as males of the same age to not meet their requirements (17% compared with 5%).

Less than 5% of the population exceeded the UL for phosphorus.
