Dietary Elements = Dietary Minerals
Calcium, Iron, Magnesium, Zinc, Potassium, Sodium and so on
They appear on the periodic table of elements and have a lower and upper limit of consumption based on age and gender but do not change with activity level suggesting to me the guidelines are probably wrong
The official amounts for most except Sodium are found here and are not trustworthy but since I do not run human experiments I have nothing better
