Although the urinary electrolytes of Melanesians approach the European pattern amongst those able to buy European foods, the salivary and sweat electrolyte ratios remain displaced in the direction of high potassium, low sodium concentrations. Arterial blood pressures show evidence of rising with European contact, and plasma aldosterone concentration falls. But renin activity is high in all Melanesian groups and not clearly related to aldosterone, sodium status, water turnover, or blood pressure.
