The phrase "promotes good health" means that it improves health and lessens the risk of illness and disease. Moreover, there must be substantial scientific proof of any such benefits, but such effects should not fall into the category of medical treatment.
所謂的保健功效，是指能增進民眾健康、減少疾病危害風險，且具有實質科學證據的功效，但非屬於治療、矯正人類疾病的醫療效能。
