It is a disease condition in which the amount or concentration of one or more mineral elements known to be essential to human health is found to be low and detrimental to health. Mineral deficiency diseases (MDD) are worth looking into as they could be very drastic, sometimes leading to death or permanent disabilities.

The mineral load of five essential major elements (Ca, Mg, P, K and Na), and nine trace elements (Cr, Co, Cu, Fe, Mn, Mo, Ni, Se and Zn) and three toxic trace elements (As, Cd, and Pb) were quantified in 4) types of Malaysian food dishes samples. The samples were oven dried, homogenised and wet ashed with nitric acid and hydrogen peroxide. The elements were determined using flame photometry, flame atomic absorption spectrometry and inductively coupled plasma mass spectrometry. All of the studied elements were present in the samples. They have good food quality ratios of Ca:P (0.1-2.5) and K:Na (0.9-2.9). When compared with the dietary allowance benchmarks, minimum 40% to maximum ) 80% of values as in K and Se can be met by the foods. Some of the studied foods have self-sufficient and self-supplementing tendency to be relevant in the maintenance of health and management of MDD. The foods are also within safe level. The essential elements were 0.5-63.0% of Upper Tolerable Limit (UL), while, the trace elements were 0.2-77.3% of Provisional Tolerable Daily Intake (PTD1).
