Phosphorus
RDA from 400 to 775 mg
Phosphorus is a very abundant mineral in the body, is vital for energy production and enables the B vitamins to work properly.
Where do you get it?
It is found in meat, poultry, eggs and seeds. Colas and other fizzy drinks contain a lot of phosphorus as well.
Too much:
Too much phosphorus can contribute to calcium deficiency and osteoporosis. An imbalance between calcium and phosphorus increases the risk of high blood pressure and bowel cancer.
Too little:
Deficiency is very uncommon, but symptoms can include muscle weakness, appetite loss, anaemia and increased frequency of infections.
You may need more phosphorus if you regularly drink a large amount of alcohol or take antacid preparations.
Supplement:
Supplements are rarely needed but if they are, it's important to maintain a balance with calcium and magnesium.
Having large amounts of fizzy soft drinks will disturb this balance, and over a long time may be a factor in developing osteoporosis later in life.
