Many of the native foods tested in a study by the Rural Industries Research and Development Corporation, a division of the Australian government,  found that they possessed high levels of important minerals.  All of the native herbs, spices and fruits evaluated in this study comtained three microelements important for genome health:  magnesium, zinc and calcium.

Tasmanian pepperleaf and wattleseed were identified as good sources of all these microelements.   Lemon myrtle was exceptionally rich in Ca and Anise Myrtle rich in Mg.  Among the fruits Quandong was the richest source of Mg and Zn.

Among the herbs and spices, Bush Tomato, Tasmania Pepperleaf and Wattleseed were identified as the richest sources of iron.  Bush tomato and wattleseed were the only two sources that contained selenium which is deficient in many soils and therefore foods.

Australian native fruits, herbs and spices contain an exceptionally rich composition of phenolic compounds present at relatively high levels.  With the observed multiplicity of phytochemicals, native fruits, herbs and spices may contribute greatly to diversity and enhance the health-maintaining properties of the daily diet.
