How much Phosphorus should I take daily?

Introduction

Phosphorus is a vital mineral found in the body, playing a key role in the formation of bones and teeth, as well as in the synthesis of essential molecules like ATP. Understanding the recommended daily intake of phosphorus is important for maintaining overall health.

Key Insights on Phosphorus Intake

The Recommended Dietary Allowance (RDA) for phosphorus in adults aged 19 years and older is 700 mg per day.
Despite the RDA, actual mean daily intakes of phosphorus exceed this recommendation, with reports indicating an average intake of over 1000 mg per day and even reaching 1400 mg per day in some cases.
The form of phosphorus consumed may affect its impact on the body, with certain forms potentially influencing calcium absorption differently.
Historical data from Britain shows average daily phosphorus intakes of 1310 mg per person in 1975 and 1223 mg per person in 1982, both above the US recommendations but below the maximum tolerable daily intakes.

Conclusion

The recommended daily intake of phosphorus for adults is 700 mg, but actual consumption often surpasses this, with average intakes commonly exceeding 1000 mg per day. It is also suggested that the form of phosphorus in the diet can have varying effects on nutrient absorption. Historical data indicates that average intakes have been consistently higher than the US recommendations, yet still within safe limits.

Inclusion of Phosphorus in the Nutrition Facts Label.

In a 2014-2015 NHANES survey, the mean daily intake of phosphorus for all age groups was over 1400 mg/d, indicating a need for phosphorus to be included on nutrition labels.

Contents of Sugar Phosphates in Major Foods and Estimated Daily Intake Level

The daily intake of sugar phosphates is 135mg, with varying levels depending on gender, age, and region.

Phosphorus in the British household food supply.

The average British household intake of phosphorus declined from 1310 mg per person per day in 1975 to 1223 mg per person per day in 1982, still above the US recommendation for adults but well below the maximum tolerable daily intake for phosphorus.

Adaptation of Young Men to High Phosphate Intake

Young men's phosphate intake may be higher than recommended, with a molar ratio of 1.25, and food tables underestimate intake.

Potential health concerns of dietary phosphorus: cancer, obesity, and hypertension

High dietary phosphorus intake may contribute to cell metabolic abnormalities and the development of chronic diseases like cancer, obesity, and hypertension.

High dietary phosphorus intake is associated with an increased risk of type 2 diabetes in the large prospective E3N cohort study.

High dietary phosphorus intake is associated with an increased risk of type 2 diabetes, potentially impacting dietary recommendations for prevention.

Scientific opinion on Dietary Reference Values for phosphorus.

The Panel on Dietetic Products, Nutrition, and Allergies (NDA) set Dietary Reference Values for phosphorus in line with those for calcium, considering the equimolar relationship between the two minerals and the potential for adaptive changes during pregnancy and lactation.

The role of phosphorus restriction in the prevention of secondary hyperparathyroidism in chronic renal disease.

Phosphorus restriction can help prevent secondary hyperparathyroidism in chronic kidney disease by regulating phosphate homeostasis and reducing the need for phosphate reabsorption.

Phosphorus nutrition and the treatment of osteoporosis.

A calcium phosphate supplement may be preferable to carbonate or citrate salts for osteoporosis treatment, as it spares food phosphorus for absorption and supports bone augmentation and maintenance.

Dietary Sources of Phosphorus among Adults in the United States: Results from NHANES 2001–2014

Dietary phosphorus intake and phosphorus density in the US increased between 2001 and 2014, with grains being the largest source and soft drinks accounting for just 3.3% of total phosphorus intake.
