The invention provides an application of health care drinking liquid containing deep seawater in the preparation of medicaments or health care products for preventing or treating hyperlipoidemia. The health care drinking liquid comprises A liquid and B liquid, wherein the A liquid is of fresh water, the B liquid is of high-concentration concentrated liquid which is obtained by performing decompression concentration on a concentrated water part which is separated from the deep sweater via a reverse osmosis device, and the hardness range is 200-1000ppm. The health care drinking liquid is given to a rat with the hyperlipoidemia, which is subjected to modeling by a high-fat emulsion, in a free drinking way, after the medicament is administrated for 28 days, the blood lipid level of the rat with the hyperlipoidemia can be significantly reduced, lipid peroxidation can be inhibited, the activity of lipoprotein metabolic enzymes, namely LCAT (lecithin-cholesterol acetyltransferase), LPL (lipoprotein lipase) and HL (hepatic lipase), can be significantly improved, and the state of lipid metabolism disorder in the rat with the hyperlipoidemia, as well as concurrent fatty liver and diabetes thereof, can be further improved. The health care drinking liquid is derived from the deep seawater, has the advantages of abundant resources, easiness in industrialization and the like, and further has broad market and application prospects in the aspect of preventing and treating the hyperlipoidemia.
