The purpose of this study was to identify food sources of major minerals such as calcium (Ca), phosphorus (P), sodium (Na) and potassium (K), and to evaluate the relationship between dietary intake of these minerals and serum lipids in healthy Korean adults. A total of 132 healthy men and women completed physical examination, diet records and blood draw for analysis of lipid profiles. Results showed that the daily average mineral intake was 373.4 mg for calcium, 806.0 mg for phosphorous, 3685.8 mg for sodium, and 1938.3 mg for potassium while the calcium‐to‐phosphorus and sodium‐to‐potassium ratio was 0.5 and 2.0, respectively. The major sources for minerals were vegetables (24.9%)/fishes (19.0%) for calcium, grains (31.4%) for phosphorous, seasonings (41.6%)/vegetables (27.0%) for sodium, and vegetables (30.6%)/grains (18.5%) for potassium. The correlation analysis adjusted for age, sex, food consumption, and energy intake showed significantly positive correlation between Ca/P and the level of serum HDL cholesterol, between Na and the level of total serum cholesterol, and between Na/K and the level of serum cholesterol and LDL‐cholesterol. These data indicate that the level of mineral consumption partially contribute to serum lipid status and particularly a diet low in Ca/P ratio and high in Na/K ratio could have a negative impact on lipid metabolism.
