It is publicly recommended to intake less sodium if possible. However, it is inevitable to intake salt in daily life, especially in Korea, and there are various kinds of functional salts for replacing table salts. The objective of this study was to assess the effects of functional salt intake on levels of total cholesterol, triglyceride, high-density lipoprotein cholesterol, insulin, sodium, and chloride in the blood of rats using meta-analysis. Individual research materials were selected from academic databases such as MEDLINE, Science Direct, CINAHL, DBPIA, and KISS. Research articles published in peer-reviewed academic journals that compared purified salt and functional salts such as bamboo salts and mineral-rich salts and that experimented with a nonequivalent control group research design were selected. Two authors independently selected final articles, and only four articles were qualified for the meta-analysis. Hedges’ effect size was used to compare functional salts and purified salts. The results show that the effect size of total cholesterol, triglyceride, insulin, and chloride measures were significantly different from zero. The results imply that functional salts are possibly effective in decreasing total cholesterol, triglyceride, and chloride and increasing insulin in blood.
