CategoryDefinitionsSimilaritiesDifferencesTypical applications
Healthy lipidsLipids promoting health and preventing disease (e.g., MUFAs, PUFAs, MCTs); often overlap with nutritional lipidsOverlap with functional/nutritional lipids; focus on disease prevention and health maintenanceDefined by perceived health effects; often public-oriented termHeart-healthy oils, weight management, anti-inflammatory diets
Nutritional lipidsLipids essential for human metabolism and health, including fatty acids, phospholipids, sterols, etc.Include health-supportive fatty acids and compounds; shared sources with functional/healthy lipidsDefined by essentiality and nutritional requirementInfant formula, dietary supplements, fortified oils, daily nutrition
Functional lipidsLipids providing physiological benefits beyond basic nutrition (e.g., ω-3s, structured lipids, FAHFAs)Can all be used in foods, supplements, and clinical settings; often overlap in composition and functionDefined by added physiological roles (anti-inflammatory, metabolic benefits)Functional foods, nutraceuticals, metabolic therapy (e.g., DAG, ω-3s, phytosterols)
Bioactive lipidsLipids with direct biological activity (e.g., DHA, tocopherols, FAHFAs, odd-chain fatty acids).Overlap with functional/medical lipids in therapeutic potential.Defined by specific signaling/metabolic roles (e.g., immunomodulation, inflammation resolution).Precision nutrition, metabolic disease therapy (e.g., obesity), neurological/ immune support.
Medical lipidsLipids specifically designed or applied for medical purposes (e.g., enteral/parenteral emulsions, immune-support lipids)Can include functional and nutritional lipids depending on formulation goal (e.g., energy, immune modulation)Defined by targeted clinical use and regulatory contextEnteral/parenteral nutrition, malnutrition treatment, metabolic disorders
