A recent study led by independent research company, Nutrition Research Australia (NRAUS), has shown that pink salts embody low levels of essential nutrients and a wide variation of harmful heavy metals. Results garnered from testing 31 samples of pink salts available for purchase in Australia revealed they are unpredictable and inconsistent in nature. Wide variations in the levels of nutrients found in pink salt were significant, with iron levels ranging between 0 and 17mg/100g and in the case of calcium levels ranged between 53mg and 574mg/100g. Pink salt samples with higher concentrations of essential nutrients also comprised higher levels of heavy metals. More alarmingly, some pink salt samples contained aluminum (up to 19mg/100g) and lead (up to 0.26mg/100g, with one sample exceeding national contaminant levels) - both heavy metals that are harmful if consumed long-term or in excess.
