Sodium and potassium intakes in Ireland

There is considerable interest in the intakes of sodium and potassium, particularly in relation to the significance of these nutrients in the control of blood pressure. In the present review a number of aspects of Na and K are addressed. Methodology for assessment of intakes is described and findings for dietary intakes and dietary sources in Ireland are presented and compared with studies in the UK. The health significance of Na and K intakes is considered and the present status of dietary guidelines for Na and K is discussed in the light of recent large epidemiological studies on the relationship of dietary intakes of these elements to blood pressure.
